Minitris is NOT a Tetris clone. There are no tetrominoes, no rotations, and no clearing by filling rows.

A single coloured cell falls into a compact 4×12 well. When it lands, forming a line of 3 or more same-coloured cells — horizontally, vertically, or diagonally — clears them from the board. Remaining bricks compact downward under column gravity, potentially triggering chain reactions (cascades) that multiply your score.

The game ends on exactly one condition: when every cell in the top row is occupied. As long as even one space remains open, play continues.
