Great concept. I must admit I was a little but skeptical about it, being a non math lover, however it takes the Sudoku puzzle to the next level. Great graphics, great job. Might want to play on mute though, that trumpet noise gets annoying everytime you get something wrong. : )

I love the concept and game. Has some clean looking graphics and interface!

Like the concept. Worth the price.

This is such a fun game. Clean graphics and interface, and takes sudoku to the next level. Great game :)

Fun, challenging logic problems with a great clean look - and you dont have to be a "math person" to solve the puzzles!

Awesome for people who love doing Math in their head.

Keeps you entertained for a while! Makes you think

Fun and original, but replay value becomes limited after a while. Still good buy for a buck.

There is a problem in the mathematical calculation of the game that needs to be fixed. On hard level I was presented with a row which contained [ ] - [ ] x [ ] = 17 which is unsolvable.

Good difficulty level, visually appealing and well designed. A great value for the price!

Inventive, yet very straighforward. Challenge runs out after a while, but was worth the dollar.

Great brain teaser and easy to use as a short time killing app

Wonderful idea and executed perfectly. Best game when you just want a quick couple minutes of fun.

this game is worth the price. it would be great to either create a user name to store your time, or a way to challenge friends via wifi to see who can solve it the fastest.

I like it a lot. It is easy to catch onto.

Great game! Keeps the basic math skills sharp while staying fun. Its my go-to game any time I have a few minutes to kill. The added levels are a plus as it gives you more times to beat.

In this game, you have to place numbers in the correct position to make the equations mathematically correct. These puzzles range from quite difficult, to quite easy. The art style of this game is quite nice, and for the math-inclined, it is a nice puzzle game. I recommend this if you like to solve math-based puzzles.

Both math and problem-solving skills with different skill levels. Highly recommended!

I really love puzzle games and this one has multiple levels to satisfy your challenge level. Worth the $1, youll keep coming back to this game.
