Chain7

Chain7 is a number puzzle game where strategy is rewarded with explosive chain reactions.

Drop 7×7 numbered discs onto the game grid. Each disc clears when it touches exactly as many neighbors as its number: a 3 clears when touching 3 discs, a 7 needs all 7. Cleared discs shift the board, cracking open hidden discs and triggering cascading chains that multiply your score.

As levels progress, the pressure builds: fewer turns per level and rows of discs pushing up from below. One wrong drop could end the game. One brilliant drop can set off a massive chain combo worth thousands of points.
