How to play
- Read the target at the top of the board.
- Select one or more number tiles. The running total updates immediately.
- Submit when the running total equals the target. Clear the selection if you go over.
What this game practices
Best for learners who already know basic addition but need practice decomposing a larger total. It is less useful for introducing addition from scratch because it does not model objects or a number line.
