A simple iOS puzzle game that is devilishly fun to play. Just add positive and negative numbered blocks to one another to make all zeros.

• Lots to do: 120 levels and counting…
• Never the same: new levels bring new kinds of blocks

Player Experience Highlights
Community Insight:
We love this game. After having finished it-Im left wanting to play more. Maybe one day well get an update with more levels.
Just completed the 120 levels. 101 was the most difficult for us. It was a game we looked forward to playing when we had a few minutes of down time.
What a wonderful game–clever design, takes one easily through the basics, then gets progressively more difficult. We found ourselves infuriated to get down to a -1 that was totally unable to Zero" the remaing 1. Sometimes we had to quit & return later in a better frame of mind. It is immensely satisfying to finally complete a puzzle and move on to the next. More, please! PaulB.
You know a game is truly great when a player completes the game, resets it, then plays it all over again. Well we've done this twice now and we're about to do it a third. And it's challenging enough that we find ourselves struggling with the higher levels each time we play. Beyond that, we can't really describe why we enjoy it so much, we just do.
We just finished all the puzzles, and it was a lot of fun! We like that there are no hints or anything, so you have to actually solve the puzzles. The hardest one for us was 101. It is very satisfying to see The End when you finish them all. Definitely recommended if you want to exercise your brain muscle :-).
Very entertaining and sometimes very challenging.
We never review any app. Pretty clever. Beat all of them pretty quickly, with the exception of 74 or 76 or one of those. Clever. How about a few more levels.
Just completed the game and we were satisfied.
That was fun, but finished too soon. Like a chess problem, we can simply look at the board, and think through the possibilities before attacking a possible solution. Please make more AND solicit user challenges.
Best $1 ever spent. Couldnt put it down. Waiting for the developer to do another one.
Too bad this game no longer supported by dev.
We like games that take a bit of thought, and some careful planning. Good job.
This game drew us in with its deceptively simple concept iterated on and gradually expanded over many levels. We didnt realize that negative tiles can pass through each other provided you didnt create an unwinnable situation, which comes in handy sometimes.
One of the most addictive games out here,kindly update the interface to make it more appealing.
Okay, so after being asked to write a review after trying the game, must say that we love it. We really like puzzlers, and this one makes you think before you act, much like chess. Gotta think a few steps ahead.
Thought it was fun and we enjoyed the aspect of having to think a few moves ahead.
What a lovely experience! No ads, simple rules, visually relaxing interface, and just when we started to worry we were getting addicted / spending too much time on it, its over! Left us very satisfied.
Im so disappointed theres only 120 levels!! We want more please. Theres strategy and logic in this.
Its challenging and its a great game.
Our only complaint is IT NEEDS MORE LEVELS!!!! We finished it and now we feel an emptiness inside. Whatever will we do with our time now??? Something productive.
Need more levels! Thought there were some glitches but turns out it just took more maneuvering. Every once in awhile the game freezes up for a few seconds if you undo several moves too quickly – but still really neat game.
Yes we are definitely gaining it 5 stars because it is the only game ever that we have stuck with. Addicting? Yes. Frustrating? Yes. Now after reading all of the reviews we know we MUST figure out the 3 that have our number. After hours of failing we had to move on. But now we must figure them out. Yes, more please.
This is a great puzzle format, we would love to see more at a greater difficulty.
Finished all 120 games. #114 was the toughest. Enjoyed all the time we spent playing/solving.
We want the revise our rating back to five stars! As it turned out, the few things we complained about were not a big deal. Yes, in more than one game the total of the negative squares were not equal to the number of positive squares. But what we didn't realize was that once you completely clear the board of, say the negative squares, you get the "winner" screen even though one or more of the blue positive squares remain. The other complaint we had was that the game often "grayed out" which prevented us from going any further. But we discovered this only happens when we hit the "back arrow" to try again but don't give the game adequate time to reset. Instead, we would IMMEDIATELY try making a new move which turned out to be the problem. This has to be one of the most fun games we've ever played and the hope to see additional levels real soon. We're not a big game player so coming from us that's really good.
We really enjoy this, at our own pace, game. Graphics are great, puzzles are great. The only thing we wish this game had was hints for whenever we get stuck.
This is an awesome game and was quite challenging at times which we really enjoyed. There are only 120 puzzles – we need more puzzles and would be willing to pay for additional puzzles!!! This game is for folks that like mental challenge games.
120 levels of challenge – some tutorial; some very challenging! Compliments to the designers/programmers – a welcome, unique, entertaining game.
We finished all the levels & hope you add more in the future. Thanks for the fun.
Just challenging enough. We enjoyed the puzzles.
We love this game, it's challenging and slowly adds to the challenges without overwhelming you. We just can't get past level 58!!! Is there a glitch in the Matrix? Programmers, players, anyone…please help so we don't start going into withdrawals.
Great exercise for your brain. Loved it. Hope they add more levels. Recommend.
More levels please! Excellent concept.
We found it addicting and pretty challenging.
This game is a logic numbers puzzle that will keep you engaged and wanting more. Great app.
Great game but should have more boards.
This is what a game app should be: clean design, easy to use, challenging.
From easy to extremely difficult. These puzzles will keep you coming back for more. Excellent.
This is a wonderfully engaging game. The interface and mechanics are simple and easy to figure out, leaving the puzzles free to become challenging and engaging. We like the lack of detracting distractions like scoreboards, social media, and timers.
We really liked this game. Simple but addictive. Had One level that took us a while to figure out. This was definitely worth it.
We enjoyed getting through 120 levels in a few days time. Some of these levels took almost an hour of replays to get through. We highly recommend this game. We think we gained an IQ point.
We highly recommend this addictive puzzle game. Hope they come out with more levels.
Simple mechanics, minimalistic design and smooth gameplay. Reminds us of one of our other favorite puzzlers, "10 The Game" by IOJoe. Looking forward to new levels.
Our family is hooked on this puzzling strategy game.
Well thought out, and well designed. Fun puzzle game.
Challenging puzzles. But we're hooked.
It was a good game, we wish there were more stages.
This game is challenging & fun! But needs more levels.
Only negative is the puzzles stop after 120.
We liked the variability of the solutions.
