JunkbotAnother game by the talented gameLab crew, Junkbot offers Lemmings-like gameplay in a Shockwave action puzzler that is both simple and fun to play. From Lego.

A character that fondly reminds me of the unbelievably creative and addictive ChipWits game for the original 128K Macintosh, Junkbot is always on the move, walking and looking for garbage to eat. Its movement is governed by strict rules of play: it will only step up or down the height of one Lego block at a time, and it won't step over gaps wider than one Lego unit. There are also obstacles to avoid, such as water, heat, and other moving bots. By building with the available Lego blocks, the object is to reassemble the level and guide Junkbot to all of the garbage cans so he can eat. For an additional challenge, each level has associated with it a maximum number of moves that can be made to earn a Gold card. Collect Gold cards to gain access to more buildings with even more levels.

The game features primary colored Lego blocks, appealing environments made up of pixel graphics, and a unique techno soundtrack containing lots of robotic sounds and effects. Together these elements evoke a consistent theme and give the game an engaging quality that is both playful and fun. Additionally, all of the Lego blocks in each level may be stacked together and reassembled by the player, which creates a compelling and rewarding sense of agency in the game. These qualities are elements of good game design.

Play Junkbot

And when you're finished with the original Junkbot, there's Undercover Junkbot that offers new hazards and secrets to uncover, and over 60 more levels to play.

(Please allow page to fully load for spoiler tags to be functional.)

Junkbot Tips.

1. Don't waste moves blocking rain drops.

2. Every level that has eyebots has a perfect time to move junkbot to trap/evade them.

3. Moving stacks of bricks does NOT always give you the least number of moves for a level.

4. If you try to solve a level backwards, you will probably find a way to do it in less moves.


Wow, so much fun! That site is full of neat games, actually. I really like Inventor Saves the Day... kind of an Incredible Machine sort of thing.

Jackson May 8, 2005 2:53 PM

Junkbot is a really cool and fun game and i really love it! This awesome and fun game has levels that really fill the bill on their building numbers: 1,2,3 and 4. My favorite ones are: 2 to 4, but, without building 1, I myself would not be able to go to the others, so I can count on 1.


I love Junkbot and have two questions for any other Junkbot fanatics out there: 1) does anyone know if Lego has plans to do a third incarnation (I've played Junkbot and Junkbot Undercover both through several times already); and 2) there are a couple of levels in Undercover that I find absolutely impossible to solve, even using the hints. If anyone else has had similar problems, I'd love to trade notes.




on the original junkbot, i have every gold medal except for the "Trapped in the Freezer" level. i can only finish it in 27 moves, rather than 20.


nevermind, i have all gold medals now. if you need help on a level for getting gold you can email me.


I, too, love Junkbot. I have been able to get through every level but one.

Junkbot Undercover, Lower Building 4, Level 13 - System Administration.

I cannot keep the top button laser from going back on. Has anyone gotten it at all????

Please... someone....HELP!!!!

... purplecat

purpledog March 5, 2006 4:45 PM

purplecat, I've been looking for the answer for some time now too, though, I believe, not as long as you. I've finally found the answer. If you place a tower of blocks just past the switch, so that junkbot doesn't get off the switch before he turns around. The best I can do on that level so far is 38, but I'm working at it. That was the last level I had out of all of them. My total is a dismal 690 moves. Good luck.

- purpledog


I can not get the gold cards on these 3 levels playing the original Junkbot:

Building 2, Level 9- Trapped in the Freezer

Building 3, Level 5 Thermostat and Level 11 Junkbot's Lucky Number

Any help would be greatly appreciated.


Yay!! 100%on Junkbot 1 and 2!!

Ann-Sofie August 24, 2006 3:29 PM

Hi! Anyone who knows what to do in Junkbot 2, building 3 level 13? I have been trying for a while and I am stuck!! The hint is not a very good help for me =(


Junkbot 2 Building 3 Level 13

Move the left stack of bricks right up against the Laser to block it, once Junkbot is on the grate lift the right stack. this will get Junkbot moving in the correct direction.


Can anyone help me with Junkbot Undercover, Level 2, #15 (Titled "under the rainbow"? I'm having a terrible time of it. Can't do it in any moves, let alone the gold key number. Heeeelp! Thx!


im stuck on the trapped in a freezer lvl in building 2. can some one tell me how to do this lvl



Building 3, lvl 5:

blocking the left hand side of the switch so that junkbot has to turn on the switch...


junkbot, building 2, Pardon Me. I can't get past it.


I cant get past buildin 2

trapped July 16, 2007 8:31 PM

How do you do trapped in the freezer!!!??

wilden12 July 19, 2007 11:12 AM

I can't get past the top switch in system adminstration (building 4). I blocked the two lower ones as suggested above, but you can't get a stack of bricks behind the top one. Help!!


I've beaten this whole game, so ask

jaradtke July 24, 2007 2:45 PM

For the top switch in bldg 4: System Adminstration - block in front of the top switch right after Junkbot passes. He comes back, hits the switch a second time, and turns around on it - now remove the block. Then his second return trip leaves the switch off.


Level 14.
Building one.
'Nuff said.


I really like both, Junkbot and Undercover Junkbot. But, could anyone tell me if there is a way to save your game? So you dpn't have to start over at level 1 every time?



OK, poopy or NotTelling, how do you get gold medal on trapped in the freezer? Never been able to pull that off.

brainsucker February 1, 2008 4:10 PM

Blar gar, laundry room isn't too tough.
Use the existing stair sets on the pile of bricks. Using some other bricks, jam up the crates at the top right on both sides so Junkbot can walk over them. When he's walking back, get him to push the crate off.. or something like that. The key in laundry room is to use the staircases that are already there.
Dewed, the game automatically saves if you have a lego account. That is, Junkbot undercover. I'm not sure about Junkbot, but i think it is similar.


how do you finish the last level?! The hint makes no sense!!!

Dan8543 May 12, 2008 1:52 PM

I play Junkbot (the original) now, but I can't past this level:
Building 2 Level 4
Maybe I am the stupid, but I played this game once in the past, and I can't remember how to do it.
Can you help me?

Steveyboy May 13, 2008 10:42 AM

This game is great. But I can't get gold medals in these 4 levels in the original Junkbot
(all from building 2):
- Level 7 : Internal Combustion
- Level 9 : Trapped in the Freezer
- Level 10: The Think Tank
- Level 12: The Garage
Please help me, I want to do this in gold time!

in the original Junkbot
I need help on Building 3, level 6- Windy Bridge
I can't seem to complete it.

Anonymous July 2, 2008 7:12 PM

I beat the windy bridge level, so disregard my previous message

sonic6335 July 6, 2008 12:24 AM

i cant get past pardon me in junkbot 1


This is how to beat Pardon Me:

Make a flat surface that the gearbot will go on and over to the other platform. Then, trap the gearbot on that platform. Now Junkbot is safe, and he can climb up to the platform containing the trash can without any trouble.

klutzedufus September 12, 2008 5:37 PM

I can't get past junkbot's lucky number building 3 in the original game.


what is project x?

dorkbot May 3, 2009 1:45 AM

I love how much replay value Junkbot has. It's really surprising how many moves you can sometimes shave off of what you used to think was an optimal solution.

I haven't made it into the hall of fame yet, so I'm curious about the minimum number of moves for each level.

Fortunately there's an easy way to compare notes on this subject. If you're logged into the LEGO account you played Junkbot with, just visit this link:


Copy and paste the middle part into your reply. Mine currently looks like this (my rank is 291):

1 1,2 1,3 3,4 1,5 4,6 2,7 5,8 3,9 4,10 2,11 3,12 3,13 3,14 4,15 11,16 1,17 2,18 1,19 5,20 3,21 5,22 10,23 6,24 14,25 7,26 1,27 7,28 13,29 4,30 4,31 5,32 7,33 6,34 11,35 3,36 6,37 1,38 19,39 1,40 4,41 21,42 6,43 12,44 10,45 9,46 9,47 6,48 8,49 7,50 2,51 2,52 8,53 5,54 15,55 3,56 9,57 5,58 5,59 8,60 1

(If it's not obvious, the first number in each pair is the level number, and the second is the number of moves for that level. It might be a little confusing because you expect the commas and spaces to be reversed.)


OMG i can not get through that level 13 #1 building in junkbot one i cant get a gold card..... HELP?!?!?!?!

ALFERALFER March 23, 2010 3:20 PM

I was wondering if anyone is still trying to get on the Junkbot Hall of fame.

ser_ser_i March 24, 2010 11:58 PM

i was one of them till i get 18th rank, i also posted you on a forum to share number of moves but i dont remember if you got the message or not, it was too long ago. Congratulations, really loved what you did in jb, :) peace

ALFERALFER March 25, 2010 7:05 PM

It only took me 6 or 7 years to pass TheSkyRacer.
I posted some spoilers on youtube if anyone wants to look at them.
If you need help on any other levels leave a comment here.

ser_ser_i March 28, 2010 12:40 PM

i dont understand, is skyracer another game?
anyway i just want to know how any moves for sys administaration, i am sure mine is too much. "18"
alfer i have 8 levels done with 10 moves or more, and u?
Thanks , peace

ser_ser_i March 28, 2010 12:54 PM

btw alfer, i just checked youtube and dont believe u shared almost all levels on tube :)

ALFERALFER March 28, 2010 4:41 PM

Junkbot 3 levels of 10 and 2 more than 10 moves.
(qualifer junkbot 1, building 3, level 8 working in the rain can take only 10 moves if you miss all the drips, I still have 11 moves on this one and it's the only level I am currently playing in both games.

Junkbot Undercover 1 level of 10 and 1 more than 10 moves.

Look at the hall of fame for THESKYRACER.

And NO I did not share all of the levels........

ser_ser_i March 29, 2010 6:58 PM

thanks for the info
And thanks for not sharing all of the levels, cos we all suffered much to be in hall of fame :)

this will be a new beginning for me, i was away from junkbot for a while and now i am happy to have the information you gave and will try to use that key to make it better.

btw is SKYRACER is your other account or what? i didnt get the point.

hope to meet you in top 3 of hall of fame master :)

peace be with you

ALFERALFER March 29, 2010 7:48 PM

I was chasing THESKYRACER's score now you get to chase mine.............................

ser_ser_i March 29, 2010 9:05 PM

i see... i guess it will be long and pleasurable chase

ALFERALFER April 1, 2010 5:09 PM

Here is the best hints I can give anyone trying to get into the hall of fame.
Drips? don't worry about them.
Eyebots are your friend. (they will change direction after a certain number of moves, use that fact to your advantage).
Get cpukiller to slow your computer down (some moves are nearly impossible without it).
Try everyway of moving the pieces you can think of(every if they don't seem to be helpful at time.
If you find 6 or 7 different ways to get (10) or whatever on a level (there is a way to get one move).

ser_ser_i April 11, 2010 7:59 AM

is there anyone who did rise and shine less than 7 moves?

ALFERALFER April 11, 2010 1:01 PM

I can't find a way for 6

ser_ser_i April 12, 2010 9:18 AM

i have just recognized that igotoofar is also here and you wrote credits for theskyracer or igotoofarlego on utube, are you all friends or is this fellowship of junkbot :)

ALFERALFER April 12, 2010 8:23 PM

I don't know the skyracer, I never was able to find any info for him on the internet.

igotoofar, mmillere and schmiede are all people i know now.

BenAlbert August 12, 2010 6:33 PM


Thanks for the hints. Very helpful.

We are still trying to improve on Junkbot.

Did you manage to do The Heist in three moves?
(Junkbot 2 Building 2 Room 10)

Thanks for the reply.

PadowanDan200 October 20, 2010 1:23 PM

Hey! Alferalfer are you still reading this?

I managed to cut down my Junkbot Undercover score by 19 moves after finding your videos on youtube. They all helped apart from Rock Climbing Gym - which I had already done in 9 moves.

Thanks to you I'm now 83rd in the Hall of Fame!

I'm after some tips about which levels I should work on next - in other words where can I get the biggest improvement?

For the 1st level underground my scores are:
1 - 4
2 - 2
3 - 3
4 - 2
5 - 3
6 - 4
7 - 9
8 - 5
9 - 1
10 - 7
11 - 3
12 - 5
13 - 8
14 - 6
15 - 10
where can I do better?

What did you do system administration in? I'm too embarassed to say my 20+ moves!

All the best


BenAlbert December 8, 2010 6:45 PM

Hey, er, PadowanDan,
I have Level 6 Elementary in 3, and Level 10 Surveillance System in 6, but I think that's it for the first room.
Oh, and System Administration (this is by no means the best, I just haven't gotten around to doing it properly yet) I've done in 18. There's a few tricks that you've got to take advantage of, like the trapping of the eyebot that can also become a bridge.
I'll tell you when I've come to a final conclusion about it, but I'd really wait for Alferalfer's verdict on them all. This is just for until he replies.
P.S. Although 15th on the leader board, there's still a lot more for me to do. So have a good look around.

ALFERALFER January 21, 2011 12:49 PM

Did you manage to do The Heist in three moves?
(Junkbot 2 Building 2 Room 10)

Yes, the rain ones can all be done without blocking the rain.

ALFERALFER January 21, 2011 12:54 PM

I think 18 is almost the best score for system administration .

I have 18, BUT it is a level that has many ways to get 18.

I have found that if a level has a lot ways to get some score (like 8), there is a way to do it in one less (like 7).

ALFERALFER January 21, 2011 12:56 PM

Are you guys even trying?

Level 10 Surveillance System in 6 or 7?

Play until you get it done in 5.

PadowanDan200 February 23, 2011 2:34 PM

AlferAlfer and BenAlbert,

Thanks for your comments and hints. I'm now at #67! (374 moves)

I've now done Elementary (1-6) in 3.
Still stuck on Surveillance System (1-10) in 7- just can't get the timing right!
System Admin - I've come down a bit, but still over 20! (but I'm working on it!)
The Heist (2-10) - I can see how it can be done in 3 - but the timing seems impossible - I empty the trash can - but the rain gets me before the level finishes!

Any hints which levels in Room 2 I should look at - these are my scores:
1 - 10
2 - 8
3 - 2
4 - 8
5 - 8
6 - 7
7 - 8
8 - 7
9 - 10
10 - 5
11 - 5
12 - 12
13 - 3
14 - 6
15 - 11

All the best,



Dan, Dan, Dan.......
Your scores on level 2 are 20 over mine.

PadowanDan200 March 1, 2011 2:03 PM


I know......but where can I get the most?

Please give me some motivation here!

All the best,


ALFERALFER March 1, 2011 5:34 PM


The most moves for any level in level 2 of junkbot undercover is 10.

Only level 2-12 is 10 everything else is less than 10.

That should give you at least 6 moves to find.

Get to work.

PadowanDan200 March 3, 2011 6:39 PM


Now done Laser Wire in 9, and that was with blocking both flybots...

The work continues.

PadowanDan200 March 3, 2011 7:12 PM

...and Crawling Through Vents also down to 9 - but suspect there is at least one move it is still possible to take out...

PadowanDan200 March 9, 2011 4:40 PM

...Laser Lab in 9 and Return to Laser Lab in 10...done.

So I've got the six moves - will continue to look for the next 14...

Thanks for the support.


ALFERALFER March 13, 2011 9:22 PM

Just to make you feel bad,

You are not done with 4 you listed.

2 of them can go lower.


Beartown March 23, 2011 3:26 PM

Hello everyone!

I just discovered Junkbot for the first time in about nine years, and it's so cool to find a place where some of the top scorers are together.

I've been playing for about a week now and I'm down to 303 moves in Junkbot 1. I don't have the time to really give it my all, but maybe I'll whittle it down in the future.

Just one piece of advice to other players out there: have fun! It should be less of a competition against others than it should be a challenge to yourself, to see if you can think outside the box.


in_dubio April 19, 2011 3:05 AM

Hmm... what plugin do I need to play this? All the browser tells me is that the plugin is missing, but there's no way to find out how to fix the problem..

[There is a "Platform" indicator in the review header of every review that tells what platform technology is required for the game. In this case, it's Shockwave, and there's a link "plug-in info" provided where you can download the latest version. -Jay]

SonicMiddleAge April 19, 2011 9:56 AM

Had a bit of trouble getting this one working - got into a 'Shockwave is installing' endless loop. Found that the 'Allow backward compatability' box on the Shockwave properties needed to be unchecked.

I'm on Windows 7 & Firefox 4 with the latest version of Shockwave (11.5.9r620) and the instructions below worked for me:

- Go to the Adboe Shockwave test page: http://www.adobe.com/shockwave/welcome/

- Right click on the 'Installation Complete' animation and select the 'Properties..' option.

- In the popup window titled 'Shockwave Settings' uncheck the box for 'Allow backward compatability' and click OK.

Go back and refresh the game window and it works.

Hope this helps.

ALFERALFER August 15, 2011 3:25 PM

Even I am not done yet.

I just posted a new video on youtube.

Junkbot Undercover level 3 building 8
Rock Climbing Gym

8 moves, it is intended to show peeps that moving stacks of bricks is not always the best way to solve a level.

ALFERALFER August 26, 2011 2:57 PM

Junkbot is 10 years old. (sorry junkbot, I was 2 weeks late).

Date: Fri, 10 Aug 2001 21:28:38 GMT

This morning, we also launched Junkbot, the Build section's first game. In
Junkbot, you have to help a garbage-loving robot get around a big, dangerous
factory by building stairs, bridges, and walls out of LEGO bricks. It's our
attempt to make an online game built around the basic connection principles
of LEGO studs.

ALFERALFER August 31, 2011 5:39 PM

Junkbot Tips.

1. Don't waste moves blocking rain drops.

2. Every level that has eyebots has a perfect time to move junkbot to trap/evade them.

3. Moving stacks of bricks does NOT always give you the least number of moves for a level.

4. If you try to solve a level backwards, you will probably find a way to do it in less moves.


In Junkbot Undercover there is 1 level that takes 10 moves and 1 that takes 18.

Every other one is less than 10 moves.

In Junkbot there are 3 levels that take 10 moves and 1 that takes 13 and 1 that takes 15.

Every other one is less than 10 moves.

That info should be of some great help to those who are trying to find out which levels to look for moves in.


I am going to post a new youtube video.

Junkbot Undercover
Level 3
Building 2 Changing the Lightbulbs

7 moves.

Nastassja October 20, 2011 3:18 PM

I absolutely LOVE Junkbot and I've played it since I was in Kindergarten- it's really familiar with me- so the thing is, some levels, just... are so frustrating! I can never seem to get it in the right number of moves! It's like- it seems like the number of moves they give you is impossible for anybody! They give you 2 and it feels like you need to take up 13 moves every time. Anyone with similar problems... please tell me! I'd love to discuss it with you!
Sincerly Yours,

ser_ser_i November 7, 2011 6:43 PM

hey guys,
i hava a new record!!!
i can do "under the rainbow" (jb 2 level 2 , 15) in ten moves in more than hundred different ways :))


i still have 17 moves in working in the rain.
i gonna cry :))))
i hate long and drip counting levels.
anyway, life has a meaning with junkbot. and with gearbot, flybot, and with bricks bricks bricks.
i believe i will have a house soon if i keep moving those bricks.
longlive junkbot..
aaalll haaaiiiillllll, king of da looossseeeerrrssssss:))
dont get me wrong alfer, i love junkbot like you but i hate him too, i have very complex feelings in the last few days. i'll make a decision and i'll let all junkbot lovers know. :)

ALFERALFER November 17, 2011 4:13 PM

Rainbow = 9
Working in the Rain = 11 (I have a 10 setup but the last drip hits me).

ALFERALFER November 17, 2011 4:16 PM

Rainbow hint.

The first move of the yellow stack is the key.

You have to put in the one and only perfect spot. Then you get it in 9 moves.


thank you so much alfer, for the tips.
it is so nice to hear from you, i hope everything goes well for you, we have to take care each other cos there are too few junkbot lovers out there.
all hail Frank Lantz, Eric Zimmerman, Nick Fortugno.


I have been chasing skyracer and alfer for years and here they are. I once corresponded with locmotiveguy once or twice to talk about the game.

One of the most satisfying moments in my gaming was solving project x using no blockers.

The Junkbot games are amazing.

ALFERALFER January 11, 2013 2:38 PM

Now that LEGO stopped hosting junkbot & undercover, has anyone found a place that allows you to play the game AND also saves your current progress.

[I don't think you will find a site that is able to save progress other than the original Lego site. It's a (relatively) old Shockwave game, a technology that has not been as well-supported as Flash has been over the years. It's a miracle if you can get them to run at all anymore. -Jay]

ALFERALFER February 20, 2013 1:42 PM

Thanks for the update Jay.

The SQL backend was https so it was not backed up. But both games play perfectly.


Found the game on the old Lego site through The Wayback Machine! However, it doesn't save, so I'm sorry, guys :(


whyis it when I leave the game it makes me start all over again im sick of this help


I don't understand why I have to start every game all over again if I leave and com back why cant I resume where I left off I hate playing this game


so cool to see the maestro alferalfer here, I cracked the top 10 in 2004 or so alo was in touch with another top ten locomotive guy- I never slowed my PC but could see how that could help.

Best feeling was figuring out Proect X and doing it RIGHT!

Junkbotted November 15, 2016 2:11 AM

For those who don't know, you can now play Junkbot *and* save your progress, provided you run a local webserver when you want to play. The process is detailed in this StackExchange answer.

I've been having a lot of fun revisiting this game 10+ years on. Does anyone know the lowest hall of fame scores when the game was active on the LEGO site? It'd be nice to have a benchmark to compete against.
