How to play Sum Ten
Tap a connected chain of tiles whose values add to exactly 10. Those tiles clear, new numbers fall in, and you score. A chain over 10 starts over. There are no lives—only a climbing total.
Controls
Tap a starting tile, then tap a touching neighbor to grow the chain. A sum of 10 clears the chain. A sum over 10 starts a new chain from the last tap. Tapping a selected tile trims the chain back to that tile.
Scoring and lives
Each clear is worth 10. There are no lives. Shuffle whenever the board looks stuck. New numbers fall into cleared holes, so a clear can set up the next 10.
Habits that raise the ceiling
Look for 9+1 and 6+4 before you start a long snake. Keep the chain on one region so a trim is cheap. If the sum is 8, hunt a 2 instead of adding a 5.
Common mistakes
- Adding a large tile when you only needed one or two more
- Starting a chain in the middle of a useful 9
- Ignoring two tiles that already make 10 in favor of a five-step path
A two-minute drill
Clear five tens using only two-tile pairs. If you need a third tile, skip that chain. The drill trains the easy 10s.
