Number puzzles for the iPhone and iPod touch.
The goal is to turn all the numbers in a 5×5 grid to zeros in as few moves as you can.
There are two kinds of moves: rotation moves and math moves.
Rotation moves allow you to rotate a row left/right or a column up/down while math moves allow you to add one to a row/column or subtract one from a row/column.
Your score for a given puzzle is determined from the number of moves you used to solve it. Specifically, the score is calculated by dividing the world record move count by your personal best move count for that puzzle. If you tie or beat the world record, a perfect score of 100% will be given for that puzzle.
Numbrosia comes with 1000 puzzles that you can redo over and over again to improve your scores.
