How to play
- Drag an operator (+, −, ×, ÷) between two connected number tiles to merge them together.
- Merge number tiles until you reach 100 with one tile remaining.
Operators can be reused. Subtraction and division always place the larger number first. Division must be exact.
Useful pairs
These number pairs can help you reach 100. Look for opportunities to make them as you play.
