This just dropped in the submission box (Thanks, Jeff!) and I scrambled to get it up just as fast as I could.
I/O is a brain-teaser of a puzzle game along the lines of the fabulous Click Drag Type series that comes with no instructions. In fact, this puzzle was also designed by Simple Andy, the creative force behind Click Drag Type.
Use your skills of discovery, intuition and creative problem solving to figure out what must be done to arrive at a solution. You will have to click-drag the puzzle around since it will not all fit within the game window.
Hints and tips may be necessary, but please use spoiler tags when posting spoilers in the comments. Play I/O.

Was fun, but a bit easy once you got it. I did it in 11 minutes, would have been much faster, but I accidentally misclicked on the last number and had to do it over again.
Posted by: BoneMan | February 7, 2008 5:35 PM
Wow! Did it. Took me 15 minutes but I did it! Fairly easy once you figure it out
Posted by: Lee | February 7, 2008 5:36 PM
Basically, this game is awesome.
If you're having trouble figuring it out, just click on more things.

Fun, but not hard once you figure it out. I completed it on my first try in 9 minutes.

Solved in 9 minutes.
The dragging served no purpose other than player annoyance, as everything could have easily fit in the visible area with a more compact layout.

Awesome cool game! Figured it out and solved it in 20 minutes.

Quite nice, once you figure out what the buttons do it's very straightforward. But I must admit I liked better the ClickDragType series. Numbers aren't my thing :)
I found an easy way to complete the game:

I liked that one.
It took me quite a while to realize that you had to drag the board to get to all parts of it though.

Oh man.
I've been trying this one for some minutes now and the only thing I can clearly see that it's either gonna be a five-star rating or a one-star one :DDDD

I was actually a little disappointed once I figured it out. Maybe it would be more interesting if the high scores were based on the number of moves, rather than on time.

Cute little puzzle. Was rather simple after cracking the code, which was somewhat disappointing, but it never claimed to be some impossible or mind-blowing experience. Props for being a decent coffee-break time waster!
8 minutes for me, by the way. =P

I liked that a lot! Took me 12 mins, and was a great deal of fun once I knew what to do. Caya, it requires basic addition, but it's a great little diversion.

Caya if this math is not to high for you, the games math level is not too complicated for you.
1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
4 + 1 = 5
5 + 1 = 6
6 + 1 = 7
7 + 1 = 8
8 + 1 = 9
9 + 1 = 10
and so on.
cando?

i'm not even kidding you, i seriously had a dream last night where there was a computer with "click drag type 4.0" on it... i knew it had to be some sort of bizarre omen...
cheers to andy! while it was a really short puzzle, it fulfilled something i was obviously subconsciously craving! thank you andy! (cough! make cdt4! cough! pleeease!)

February 7, 2008 7:03 PM
great game. I love simple andy's games. I think this one could have been a bit better with randomly generated numbers though. or at least a few different sets, for higher replay value.

Hey everyone! I am glad to see it made it on JayIsGames.com! Smart-kit asked me a while back if I had any puzzles that I should let them know so I did some brainstorming here and there. I had a couple of great ideas written down, but some of them are going to take a lot of time (maybe future cdt4), but I knew this one I could do in a night... so i did, published it, and here it is on the net a month later! WooHoo! Thanks to everyone who plays it! And thanks to Smart-kit for sponsorship and Jay because his website is magical!! Seriously, I wouldn't be nearly as successful without this place! I went from CDT2 and 3, to the game competition on this site, which got me offers to make games for NFL Rush Zone and Urbaniacs, which filled up my resume, now I am working on the South Dakota State University (where i am at now) EE/CSC department website and just today got a internship at IBM for the summer! Jay and everyone who works/plays/comments on this site is amazing! THANKS everyone!!!

This game was a cool little puzzle, however, once I played around with it, I found it very familiar:

7 minutes. Kind of simple. Could've been spiced up by changing the nature of the numbers (so players had to figure out what symbol meant what number).

Now that I've beat it (9 minutes), I wonder what the optimal solution would be.
What are the LEAST number of moves needed to solve this puzzle?
Posted by: Phoenix | February 7, 2008 8:45 PM
Nice little game, simple once you've got it started, as well as short, but still a nice brainteaser to occupy you for a bit.

Very nice. 11 minutes for me. I kept getting the buttons mixed up on the memory registers.

February 7, 2008 9:33 PM
Don't worry about it Hand-E-Food, I did as well. I figured out the basics fairly fast, but I messed up many times by clicking the wrong button. The game is neither long nor difficult, so it wasn't too much of an annoyance, but I imagine many had this problem.

That was pretty cool. Solved it in 18 minutes. Kept messing up on which button did what until I got the labels straight in my mind.
I kind of took the easy way out on one or two of the numbers:

I kept getting the buttons mixed up, and had to restart a few times. Eventually, I just looked at the boxes on the bottom right (the colored ones) to figure out what was what.
I must agree with Kero on the fact that it should have randomly generated numbers, however, I didn't think to use the methods others have pointed out.
Still though, I figured I would waste a half hour, but 6 minutes? Seems like just one of the Click-Drag-Type puzzles (rather than the whole set of puzzles).

pretty easy, didn't have to use the one button with 5 on it lol
Posted by: anon | February 7, 2008 10:55 PM
That's a very good question, and it made me curious.
I can't claim that I found the minimal solution, but I found a very minimal one, and interestingly it doesn't use 1 at all. It takes 23 IOs.
It's written as one letter for the method and the rest to signify the block. BL meaning the left orange block, BR the right orange block, R, Y, G, B meaning the coloured blocks, and the numbered ones simply the blocks that contain that number at the current time.
I'm gonna try to see if I can make a more minimal sequence.

Oops, the question I mentioned is the one Phoenix asked, IF anybody should be in doubt.

February 7, 2008 11:29 PM
Jay, sorry for triple-posting.
But I just tried a solution using the 1, and it takes one less steps to make a 9 in one of the orange blocks. So my solution is down to 22 steps, by replacing the first 4 steps in my above solution with:

It is very hard to find a nice balance of puzzle difficulty. One player might take 10 times longer than another, but I don't want those players to give up due to difficulty. I played with the numbers and 'registers' or 'nodes' for a while to make sure that the player would most likely make a mistake the first time through, like overwriting a necessary number. I did want to, and should have, implemented a move-counter to promote a challenge of 'who can get the lease amount of moves'. I learned about the basic components of a processor in Digital Systems, which is what the puzzle is based around. Maybe next time around I'll take what I know from Compiler Construction and Lexical Analyzers to make your brain hurt! :)

Excellent puzzle. I'd like to see more of these.

Bit too easy for my liking, and I guess I would have preferred an intuitive interface... but I suppose that figuring it out is the main part of the puzzle.

It seems like a bit of waste of such a nice, clean interface. Perhaps a tweak should be made where the number cruncher had limited "crunches"? Because otherwise I see no other incentive to do things the hard way, when the easy way is so obvious and, well, easy.

I finished in three minutes, first try, with no help at all!
Does anyone know the fastest time?

I'm the guy who finished in three minutes. I wanted to know what is the least number of mouse clicks needed to solve the puzzle. I did it with 25 clicks.

Personal opinion: I hate it. Even after reading through all the above comments, including spoilers, clicking pointlessly for what seemed like around half an hour, I completely fail to understand how this works. It must just be my learning ability, seeing as how everyone else seems to greatly enjoy it after they figure it out. Well, I can't figure it out, nor do I even want to try anymore. This should have been called "How To Completely Frustrate Someone With A Simple Task That Everyone But You Can Comprehend." I hate to sound so bitter, but I just don't get it.

...One player might take 10 times longer than another...I'm a slow one. For me the best games are ones that you can take your time at and in which the play is the point, not finishing.
I also hate going all the way back to the beginning if I mess up. Can you imagine Life, if whenever you made a mistake you had to be a baby again?
