How to Play

You have 6 numbers and a target. Combine any of your numbers using +, −, ×, and ÷ to reach the target.

Tap a number, then an operator, then another number — they combine into a new number you can keep using.

You don't need to use all six, but each number can only be used once.

The "Undo" button steps back one move at a time and works even if you accidentally start a new game.

Large vs Small

Large numbers are 25, 50, 75, and 100. Small numbers are 1 through 10, with duplicates possible.

You always get 6 numbers total. More large numbers give you bigger building blocks, but fewer small ones to fine-tune with — it's a trade-off.

The classic mix is 2 large, 4 small. All large (4) is a serious challenge. All small (0) can be surprisingly tricky too.
