Choose a column. The incoming disc falls to the first open space. There’s no time limit in any mode.
Each number clears when it equals its complete unbroken row or column run. Gaps break rows; diagonals don’t count. Clearing discs can start a chain.

Clears next to a covered disc crack it, then reveal its number. Two neighboring clears can reveal it at once.
A covered row rises when the countdown reaches zero. If any disc is pushed above the board, the game ends. You also lose if the board remains completely full after a chain.
Longer chains earn more per disc: 7, 39, 109, 224… Survive a rising row for 7,000 points in Classic and Sequence, or 17,000 in Blitz. Empty the board for 70,000 extra points.
Sequence repeats the same board and discs every game: 7s Sequence v1. Your game stays in this tab; reloading starts fresh.
