Community Insight:
If you're pretty good at math, this is a game that's beautifully challenging and beautiful to look at as well. Perfection.
Challenging fun. One of our favorites.
Small game but a nice time pass…not as tough as a sudoku.
Great for all ages. Our kids can beat us!! Games are quick so fills up waiting times nicely.
Good app, works for many age groups.
Great game to pick up and play that doesn't take long and is fun! Keeps your mind working and sharp.
We enjoy this game just to play for fun, yet it is a challenge. Thanks for the game.
If you like math, then you should by this game.
Puzzle itself is Amazing!!! Design and Interface is Super Cool and Amazing!!! In short this is worth spending $0.99 on this cool Math Puzzle Game.
Smooth, bug free, and a great way to kill time.
Us and our boys both enjoy this challenging game. Great skill builder too.
Fun little app, great for wasting time while waiting in line or in an office. We appreciate it because we hate the mindless time-wasters. This at least challenges us, and by giving us different levels, everyone in our family can use it – even our 7y/o.
Holy cow great game worth every penny.
One of our favorite games that we've bought on our iPhone. Use it whenever we want a bit of a mental challenge. Nice job.
Very nice implementation and aesthetics! Keep up the good work.
This is a great game! It is very good at keeping your mind sharp. Doing simple math as fast as you can has never been more fun.
This is amazing! Fun and educational too! And each game is short and sweet! So it's a perfect game for waiting in line, waiting for family, at the Dr's office or something to play before you are ready to fall asleep! Thanks.
We love it. Simple and challenging.
Great way to get your brain warmed up.
We really love puzzle games and this one has multiple levels to satisfy your challenge level. Worth the $1, you'll keep coming back to this game.
Both math and problem-solving skills with different skill levels. Highly recommended.
Great game! Keeps the basic math skills sharp while staying fun. It's our go-to game any time we have a few minutes to kill. The added levels are a plus as it gives you more times to beat.
We like it a lot. It is easy to catch onto.
Great game. Beautiful interface.
Wonderful idea and executed perfectly. Best game when you just want a quick couple minutes of fun.
Great game for all levels! We love the new update because we can really push ourselves, or just play a less intense round. We're not a math fan, but really enjoy logic needed to solve the puzzle.
We really enjoy this game. It can become addictive.
We usually hate anything to do with numbers or math of any sorts, but we can't stop playing this game! Addictive and just a great game to get the brain going. Highly reccomended.
This is a great game, not really the type you'll spend hours to play. It is great when like you're bored on the bus or just waiting for something, great for quick bursts. Nice game.
We appreciate the newest version upgrades the game is awesome and continues to entertain us when we need to kill a few minutes.
We like sudoku, so we love this game. Our kids like it too. Definately worth the price.
When we first purchased it we thought "this is cool" it is much more than cool!!! We love it and it's really helped to keep math skills alive. Quick and easy to play and many levels to challenge even the best math teacher.
We like this game we play it on the bus when we go to our volleyball games. But sometimes when we get stuck we would like a hint button to help us get through our brain fart. But otherwise its a great game.
We love the simple and clean graphics, and it's a fun way to work on math skills.
We love this game. We have never sumbmitted a review before this and that says something.
This is a super one to three minute game, and every new board is tricky in a different way. We pick it up again and again as we stand in line at the movies, wait for the bus or just have a few idle minutes. It wakes up our brain and brightens our day. The graphics are attractive, gameplay smooth and the puzzles challenging enough to keep you coming back. Thanks for a fresh new idea.
This is an awesome game if you need to just brush up on your math skills or just looking for brain burning puzzle on master mode. Great job Quadion.
Really cool style, nice+simple, has all the basics (simple high scores etc), quick to get into.
It is impossible to hate what you have not loved and we hate this game with a passion… Because we love it! We're apparently a math junkie, who knew.
Excellent little game. Simple and elegant. Good for keeping you occupied for short periods of time (e.g. Waiting in line, waiting for the wife to get ready, etc.). Keeps the mind sharp! Graphics/art could be better but it's a good start.
Good game. Gets your brain warmed up.
A very fun puzzle that has been keeping us going for hours. The brilliance of this game is that thete is only one right answer for each puzzle. Challenging and a joy to play!!! Get this one before the price rises.
Okay, so it's not the most difficult game to play. It's still a lot of fun, perfect for children and challenging enough to satisfy most adults.
Grat game good to keep the brain active during summer but if its possible we are color blind so we cant really tell if the number is red or green so if you came make the colors brighter or find a may yo make it more obvious that would be awesome.
This is a great quick play game to keep on hand. Challenging yet simple. A bargain and a blast.
This is really a great time. Very simple, but yet also very challenging. The easy level will help you get used to the game, but you will find yourself updating the difficulty for more challenge. Of all our games on our iphone, this one is our favorite by far.
Very fun and addicting, sharpens math skills.. Only one complaint, it does not use order of operations. In other words anytime u have more than one type of evaluation, multiplication and division should be first then addition an subtraction. That throws you off occasionally but still a fun app.
Great game!!!!! Just one thing, please put a save option on.
So simple, so addictive. So awsome. Only played for 10 min so far and this has to be one of the best games we have played to date.
It's an easy puzzle game to pick up and is well worth the $1. You can always tell when an app had a good amount of work put in to it. The graphics are simple yet look very polished.
