★ TouchArcade is in READ ONLY mode this weekend while we upgrade. Please support us on Patreon.
App description: Clear the board by changing numbers to the target. Drag an add, subtract, multiply, or divide over a number tile to change it. Bombs clear tiles and spinners change tile numbers.

Three increasingly challenging modes of play are included: Easy, Normal, and Tricky.

Tip! Functions only work on whole numbers!
