Think fast, add to ten, and watch the board light up. Tenchain is a number puzzle game where every move can trigger a cascade of matches - drop tiles into a 5-column grid, line up numbers that sum to 10, and let chain reactions do the rest.

The rules are simple: place numbered tiles (1–9) on the board. When two or more consecutive tiles in a row or column add up to exactly 10, they clear. Cleared tiles cause the remaining pieces to fall, which can create new matches - and each chain step doubles your score multiplier. A modest 2-tile match is worth 10 points, but a 4-step cascade can earn hundreds. The deeper you think, the bigger the payoff.

Tenchain offers several ways to play. Classic Mode is an endless session where you build your score at your own pace - pause and resume whenever you like. Time-Limited Mode gives you 1 to 5 minutes to score as high as you can, adding real pressure to every decision. Speed Mode drops a 2-second timer on each move; hesitate, and the piece falls automatically. Daily Challenge presents the same puzzle to every player each day, complete with three unique goals to chase - reach a target score, survive a set number of drops, or pull off a long chain. Complete daily challenges on consecutive days to build your streak.

The game features a full progression system with six ranks from Bronze to Master, 24 achievements across skill, survival, daily, and mastery categories, and unlockable visual themes and tile skins that reward your progress. A built-in tutorial walks new players through matching, cascading, and surviving near the danger zone - you will be setting off chains within minutes.
