How to play

Tap tiles anywhere on the board, one after another, in the order you would write the equation: a number, a sign, a number, the equals sign, the answer (9 + 9 = 18). You can also drag across them, resting a moment on each tile you want. When the tiles read as a true equation they crunch, the tiles above fall, and new ones drop in. Tap a picked tile to take it back. A negative number brings its own sign, so 11 −10 = 1 works as written. Longer equations, like 4 + 5 + 3 − 1 = 11, pay up to four times the points. Reach the target score before your moves run out: one star passes a level, three is perfect.

Stuck?

Tap Hint and the game shows you an equation on the board. Every board always has plenty of equations, and a plus, a minus and an equals sign are always close at hand.

Bigger and smaller numbers

Every level starts with small numbers. Five equations in a row without the hint, using numbers of your current size, bring bigger numbers: Small, then Medium (like 23 + 17), then Big (like 53 + 44). Two misses in a row (an equation that is not true, or a move made after the hint) bring smaller ones. Bigger numbers pay more points.

Your progress

Progress saves on your device after every move. If you leave a level, the map shows Continue. Deleting the app deletes the progress.
