The tic-tac-toe/on&off light puzzle was a real pain in the *ss, I had to go through dozens of comments here until I figured the actual solution... there were like four or five different plausible ways to interprete the code and what's more, the infamous

spiral had nothing to do with this puzzle so far, a red herring or what???

Moving on...

@ genx sorry, my walkthrough is unhelpful there. what I should have said for step 20 is

note place to INPUT 3 digit roman numeral code (on door of cupboard)

@ Paul

sorry the walkthrough is not to your liking. Oftentimes it is just an achievement to get to an escape the room game without someone having already posted the walkthrough before I even play!!! On the rare occasions I'm one of the first to see it I'm so keen to complete asap and get my walkthrough up there first I probably am not super-clear. I do do my best to be as clear and concise as possible! It's hard to write instructions everyone can interpret in exactly the same way - we don't even all speak the same version of English, remember!

@ chipmunk

so it is! Was in too much of a hurry to notice!

@ Dave and Otto

so glad you fixed the problem, although I agree that that is a flaw in the game.

@ Alex

Probably. I only did it the once and assumed the bell ringing was to distract the dog long enough to drop the ball. (I'd already worked out that the dog would drop the ball as it has the ball in the picture on the desk and you can see the ball in the diagram on the folded paper behind the vase

@ ST

9800 isn't the code you need... look again at the handheld game...

I have a problem.

I have opened the locked door and revealed the secret panel behind the penguin picture. The problem is that i have not noted the codes for the 3 puzzles there. I have done them by printscreening the tips. Now i can solve the tictactoe puzzle and the duck puzzle again. But i don't have the ruler and the note paper to solve the other puzzle (the one with ABCD and diamond,star, heart symbols).

So do i have to start the game over or what ?

*I added slow and easy mode in little game in the room. If you have difficulty with normal mode, try "Easy Start" button.*

Thanks for this. My one stumbling block was the duck video game. Three tries and I still could not get high score.

(I did, eventually, but only after getting frustrated and walking away for a while!)

I liked Lights a lot... but I don't think it can surpass Vision in my heart for "greatest escape game ever." :)

** Ovyvindyr -- ** you have a piece of paper in your position which will help you and, no, you do not need the ruler. If you are stuck, just remember...

the ABDC/diamond, heart, star are places on a grid. So, for example, if you have a "C" heart in your ending code, then you push that button on the grid behind the penquin pic.

** Olga -- ** it's embarassing for me to admit, but my 14-year-old son had to explain the solar code-machine formula to me (and he solved it for me).

You can scroll up and use the link to abfdrumz's code generator -or- if you're like me and want to figure it out yourself, I'll try to explain as best I can how to solve the code...

Whatever number is on your screen is going to increase by 7. So part of the puzzle is determing when to press the middle button, shifting the digits to the left by one. All the codes will expect you to do that; knowing Neutral as a very logical puzzle maker, no code would be impossibly random.

Figuring out how to get your first two digits should be easy...once you get them, you just need to determine what third digit you'll need to have before pushing the middle button and shifting the digits left for the last time.

If you are repeatedly ending up with a number that is just a few digits off from what you need, then just divide 7 into it...

The rest, I don't think I understand well enough to explain, but you should see that whatever the remainder is should be the number you'll want to have in the that fourth digit box before you hit the middle button.

Bah, I'm not sure why I've explained all this... if abfdrumz made a code-generator, they probably understand the math of it better than me and have explained it already. ;-)

@elle, just to give credit where credit is due, OverZealous was the first to post the algorithm I ended up using.

The slightly sneaky part is that you start by "building" the code's rightmost digit and work left, then reverse the order as a final step. This prevents you from messing up the leftmost digits in the result due to carrying tens from the ones to their right.

Here's the Perl code I used, if anyone's curious:

@mult = (0,3,6,9,2,5,8,1,4,7);

$d4 = $mult[substr($R::code,3,1)];

$R::code -= 7*$d4;

$d3 = $mult[substr($R::code,2,1)];

$R::code -= 70*$d3;

$d2 = $mult[substr($R::code,1,1)];

$R::code -= 700*$d2;

$d1 = ($R::code > 0 ? $mult[substr($R::code,0,1)] : $mult[10-substr($R::code,1,1)]);

print "right x$d1, left, right x$d2, left, right x$d3, left, right x$d4";

(In case it's not clear, the @mult array is simply a list of the number of times you need to hit the right button to generate 0-9, e.g. 3x7=21 gives you a 1.)

If people are having trouble with the second ending solar box codes, I've published a google docs spreadsheet that will calculate the correct button presses. 3795 was more than I could figure out in my head. :)

PS - In the time it took me to post this link, two or three others were posted - wow. Apparently JIG people like programming challenges :)

*[Comment updated to point to a copy of the document since the original version was no longer available. -Jay]*

@Trun: this is a Neutral game. There are no bugs. :) Hard puzzles, maybe, and perhaps an arguable decision[*], but no bugs that prevent you from finishing. So if you're entering a code and it's not accepting it, it's almost certain that you're the one who is missing something.

[*]

Since you can see the tic-tac-toe sequence without actually zooming in on the doggy door, the fact that the game requires you to zoom in can be interpreted as a flaw. But a flaw is not a bug, nor is it an error: it is simply a disagreement about 'best design practices'.

Dee:

Regarding getting the screwdriver -

You hit the button THEN pull the rope from where you're sitting by the couch

Regarding the tictactoe code -

You need to actually get a closer look at the code in the hatch.

The code tells you how to transcribe the tictactoe sketch

into the proper on/off sequences at the lamp.

The spiral has nothing to do with the tictactoe puzzle.

Great game. I'll admit to having to lean heavily on the walkthrough, but it was still fun! Thanks to Neutral for adding the 'easy' mode on the handheld.

A mild hint on the solar-powered device:

For those who don't want to have to use the code-solver pages posted, here's one thing to keep in mind - as you shift the numbers left, the leftmost digits drop off - for example, say you need 37 at the start of your code. Make the box say 637 and continue with the other digits. As you shift to the left, the 6 drops out and and you have 37 where you need it.

Solar box easy math to decipher:

Getting the first two digits of your number on the solar box is easy. Then all you need to do is find a two- or three- digit number that divides by 7 into a whole number, subtract that number from your original number*, get your first two digits onto the solar box as such: XX00 (where XX are the number that you calculated at *), then add that number that divides by 7 into a whole number!

Okay, it's easier to follow an example:

Example uses number: 3676

Look at your last two digits. Can you divide by 7 and get a whole number? (76/7=10.85...) No. Add 100: Try 176/7. No. Try 276. No. Try 376. No. Try 476. Yes, it's a whole number (you don't need it, but it's 68 here). So 3676 (my number in this case) minus 476 equals 3200. Press button on right until you get the numbers 32 in a row (the screen will read 0532), then press the middle button until you have 3200. Press right button until you have added 476 and you will have exactly 3676. (And guess what? You had to push the button 68 times!)

Remember you need to change my numbers to the random number you got:)

Mario,

have you found the slotted screwdriver yet? Have you used it? Have you opened the green wall safe? Did you use the item you found there? (If you use it successfully, it disappears from your inventory.) If you've done all of those things, then it's time to use one of the first things you found which is still in your inventory - something that will let you examine faraway things a little more effectively.

The slotted screwdriver is in the green box with the ducky head. Use the screwdriver to remove the panel from the door.

There's a reason the panel ends up in your inventory!

The key for the wall safe is in at the bottom of the "chute". The code for it is in the hallway.

Use the binoculars!

The bone

... so I noted the bone. The dog is small enough to go in and out through the bars. The bone... perhaps not! Which means the dog will return to his doggy bed because that's where he keeps the bone.

At least, I like to think that's the story.

Izzy: Just tested it out. The high score remains the same. Someone using your computer beat the game with that high score...

Guys... the high score you're shooting for is 6000. It will never not be 6000, unless someone else played the game before you, in which case it's still 6000.

Where are you getting these high scores? If it's a bug, I've been playing and replaying, and never getting anything else.

It's quite possible that you haven't checked everywhere in the room yet.

Have you looked under the couch?

Did you put what you found under the couch in its place?

Have you finished the duck game and examined the screen *carefully*?

I cannot get the grid behind the picture to work!

Here's what I've done... I've lined up the ruler with the only five letters that fit in the orange shape toy.

Then, I used the scrap of paper and determined which shapes corresponded to the letters in the grid and marked them on a piece of paper.

When I punch in these results in the grid behind the picture nothing happens. I tried restarting a new game and I got the new shapes and letters, and still nothing!

What the heck am I doing wrong?

Well...

I thought I figured out how to solve the tic-tac-toe puzzle, but the idea didn't seem to work. Finally I had to use the walkthru, and - tadaaaa - it had the very idea I tried. When I "enter" the right sequence of 0's and X's nothing seems to happen.

I don't want to read through the comments because whenever I do so I unintentionally get a lot of unwanted hints.

Am I doing something wrong?

For anyone having trouble with the solar puzzle(s):

The codes in this game are random, I believe, so if you're having trouble inputting a code try writing the code you need to input on a piece of paper. Then subtract 7 from the code until you get a number ending in 0. Next, divide that number by 10. Take that number and start subtracting 7 until you get another number ending with 0. Divide that number by 10 again. Keep repeating these steps (subtracting 7 and dividing by 10) until you get a single digit number. Then go back to the game's solar calculator and reverse the process (adding 7 and multiplying by 10) until you get the code you need.

I got 6823 as one of the codes, and here's what I did:

6823-7(9 times)=6760

6760/10=676

676-7(8 times)=620

620/10=62

62-7(6 times)=20

20/10=2

Then I reversed the process and used the solar calculator, pressing the buttons until I got 2 as the last number in the row:

2x10=20

20+7(6 times)=62

62x10=620

620+7(8 times)=676

676x10=6760

6760+7(9 times)=6823

Just replace my code with yours and see if this method works. I know it may take a while to do, but it worked for me. Hope this helps!

**Tic Tac Toe puzzle**

View the code for it in close up, looking through the little door. I know, I know, you can see it from afar, but the developer wants to make sure you know to loo through the door.

@Jascha

Take the ruler and place it against the letters until there's a letter fitting *perfectly* in each shape. There's your code.

Here is the algorithm for solving the solar puzzle for any number N (even those not with four digits).

Let D represent the number of digits of N. Compute R = N (mod 7). If R = 0, then the digits of N/7 read from left to right gives the number of times you must press the right button between presses of the left button.

If R is not 0, then compute successive values of k*10^D (mod 7), for k = 1, 2, 3, ..., 6. This is easy because all you need to do is compute a = 10^D (mod 7) then k*10^D == k*a (mod 7). Then choose the value of k for which k*10^D + R == 0 (mod 7).

Compute (k*10^D + N)/7. This again gives the required sequence of right-button presses between left-button presses.

Here is an example. Let N = 9927. Then D = 4 and R = 9927 (mod 7) = 1. Since 10^D = 10^4 = 10000, we compute 10000 (mod 7) = 4. Therefore 20000 (mod 7) = 2*4 = 8 (mod 7) = 1. We continue until we find 50000 == 6 (mod 7), so k = 5. Therefore 59927 is divisible by 7, and the quotient is 8561.

This tells us that we need to press Right x 8, Left, Right x 5, Left, Right x 6, Left, Right x 1. If the quotient contains 0 as a digit, we simply press the left button twice in a row.

Try it. It sounds a lot more complicated than it actually is. The key is to find the unique digit from 0-6 that, when inserted to the left of the number, gives a number divisible by 7. You will never have to test more than 6 possibilities. There are a lot of ways of doing this--trial and error is one way but it's not the fastest. The fastest method (by hand) is the one I described, since it saves you from having to do more than 1-2 long divisions.

Someone please help!

I have been stuck on how to USE the solar box for a good half hour! (and it's very hot in my room)

What do I do? I went near the window if it needed light. I pushed all the buttons.

I have the number underneath the key.

What do i do next? I assume from all the comments something with the solar box, but I can't get it to work!

For the green grid:

You have to use the letters you got in that order, in the same shape they were, in my case, it was D diamond, A diamond, A star, B heart, C heart; otherwise DAABC. So I would click:

First Row, 4th button, 1st button

Third Row, 1st button

Second Row, 2nd button, 3rd button **in that exact order.**

Then you get the key from the lower slot. Hope this makes sense.

redrahede, it's already given you the hint! you only need to beat 6000. pay attention to the line of chicks after the game ends, then turn the chick in the box accordingly!

can someone please tell me how to use this code?

right x5, left, right x1, left, right x0, left, right x3

I'm stuck until. Thanks.

Shudog, I guess I should have been more specific. The solar box is bugged for me, none of the buttons work so I typed in my four digit number into the box at the link that was given on page 1 (specifically made for the bug). In return they gave me the code.

Which I have no idea what to do with. Multiply? How do I multiply 'right' and '5'?

Forgive me if the answer is stupidly obvious and I just can't seem to see it.

Enjoyable read, Mike. Yes, the intro is a little long winded - but to be dead honest, almost every escape game falls into one of these 4 categories now these days (if I can add one more, it would be that the game requires too much computer resources, and lags to the point where I want a walkthrough).

I guess we should be thankful that there are a lot more escapes that are in the last category than any other.

Looks like my own code generator was failing for some of the longer sequences (including 3593), plus it was hella inefficient. I've rewritten it based on OverZealous's algorithm, so now it runs instantly and should always get the right answer (fingers crossed). So between my program and paullus's, nobody should need to be stuck on those codes. Please shoot me an email if you have any trouble with it.
