Wow, this game feels a LOT like sudoku :D (I like sudoku, and this is even better!) Basically a 1/3 turn "uneven" sudoku. No, seriously (think about it - subtraction isn't the opposite of addition, but a 1/3 turn since the same number can be revealed in both)
OMG, I got all stars and was messing around, and then a puzzle with letters popped out of nowhere! Like, all the tiles were 1s, then I scrolled it, and all of the other numbers were letters! I chose the N, and then there was this "FAIL" message showing I got 0 of 3 stars, then the game reset! WTF?
The CPU is WAAAAY too easy to beat... I mean, like, I get that it's hard to program a robot of that type... Online Multiplayer please! (http://bit.ly/1XiGPzJ and http://bit.ly/24HYWkA)
