Two-cell colored pieces fall. Connect four of the same color to clear them — and trigger explosive chain reactions.
A 2-cell colored piece falls from the top of a 6×12 grid. Drag horizontally to slide it left or right, tap the grid to rotate, and swipe down to drop faster.
When the piece lands, the game looks for any group of 4+ connected cells of the same color (up/down/left/right). All those cells clear, the cells above fall down by gravity, and if the new arrangement creates another group of 4+, that's a chain — every step of the chain multiplies the points (size² × chain depth²).
The game ends when the spawn position at the top is blocked.
Don't clear at the first opportunity — set up a chain. Every cleared 4-group on its own scores 16, but a 2-chain scores 4× that, a 3-chain 9×, and so on. The trick is to stack a couple of layers of one color with a slot you intentionally leave open, dropping the key piece last so that when that group clears, the cells above fall into another waiting group, and so on. A single well-stacked chain at the end of a minute beats spamming small clears by an order of magnitude.
Gravity is your ally — only the cells directly above a cleared group fall, and they fall straight down (no horizontal movement). So plan your chains vertically: build a stack of three blues in a column with a fourth blue that will arrive once the reds underneath get cleared. The colour underneath is your timer, and the column above is your reservoir.
Keep the centre clear and stack toward the walls. The centre columns refill quickly from gravity after every clear, while a stack hugging a wall gives you a stable base to layer chains against. If you let the centre tower up, the next random piece often spawns into a half-blocked top row and ends the run with all your chain potential still unfired.
