Connect the numbers. Hit the target. Build your next great chain. Chain Math is a number puzzle game where quick thinking meets strategy. Connect neighboring tiles horizontally, vertically, or diagonally to match the target. Mix in minus tiles, multipliers, and wildcards to make every board your own. PLAY YOUR WAY Take your time in Classic or race the clock in four Timed games: 30 seconds, 1 minute, 2 minutes, or 5 minutes. Build consecutive matches into a combo and chase your personal best. A FRESH DAILY CHALLENGE Clear the daily board in Daily Clear. Race through five targets in Gauntlet. Find efficient chains and use fewer tiles in Par. Wind down with Nightcap on a calm, dark board, with no clock and no rush. STRATEGIC POWERUPS Freeze or slow the timer, connect non-adjacent tiles with Number Hop, reshuffle the board, or add minus tiles and wildcards. Clock powerups are for Timed games; tactical tools work in Classic and Timed. Earn them through play, claim daily rewards, or choose a pack in the shop. See your owned powerups in the shop before starting a game. ACHIEVEMENTS AND COMPETITION Work toward clear goals with visible progress and tier rewards. Compare Daily Clear, Gauntlet, and Par results on leaderboards and create private competition groups with friends. Game Center and iCloud are required for supported online competition features. FREE TO PLAY, WITH AN AD-FREE OPTION Occasional ads appear between completed Classic and Timed games. There are no automatic ads during a game or in Daily Clear, Gauntlet, Par, Nightcap, or Duels.

Existing Chain Math Supporters receive these benefits automatically and keep their existing perks. Optional powerup packs are sold separately. All game modes remain free to play.
