Tenfold Puzzle

Swipe to slide the whole board, add numbers together, and make 10. Lock in green 10s, then double them into golden chains: 10 → 20 → 40 → 80… Build massive combos while avoiding blocked (red) tiles created by sums over 10. Easy to learn, surprisingly deep.

How to Play

Active tiles (1–9) merge; if the sum = 10, it becomes a locked green 10.

If the sum > 10, it becomes a blocked red tile that never merges.

Chains only merge with equal values: 10+10=20, 20+20=40, etc.

A new 1–3 spawns after each valid swipe.

Scoring

+10 for each new 10.

+value for each chain merge (20/40/80…).

Streak x1–x5 on scoring moves.

+5 Clean Move bonus when you score without creating a blocked tile.
