Chain Reactions
Every tile counts its neighbors. Make the count match the number, and the tile blooms — setting off chain reactions that can clear the whole board from a single swap.
wave 1 → wave 2 → wave 3 — one swap, seven tiles
Every tile on the hex board shows a target. When the number of tiles touching it equals that target, it blooms and clears — and the board never stops reacting.
Tap any two cells — even an empty one — to swap their contents. Adjacency doesn't matter. One swap is one move.
A tile whose occupied-neighbor count equals its target clears instantly. Watch for the numbers that are one neighbor away.
Each bloom changes its neighbors' counts, which can set them off too — wave after wave, until the board falls quiet. Or falls empty.
No timers, no lives, no losing. Just you, the board, and the question of how few moves it can take.
Handcrafted levels grouped into collections of twelve, each introducing new wrinkles. Finish in fewer moves to earn up to three stars ★★★ per level.
One fresh daily board, the same for everyone. Solve it, build your streak, and share your result without spoiling the solution.
Anchored tiles are locked in place but still bloom — plan around them. Voids aren't cells at all: nothing swaps in, and nothing counts them as a neighbor.
Clearing the board is the only outcome. Take as many moves as you need, restart freely, and grab a hint when a board has you cornered.
