How to play
- Touch one of the three pieces under the board and drag it up onto the grid.
- Release when the shadow shows the spot you want — pieces cannot be rotated.
- Fill a whole row or column to clear it and score points.
- Clear on consecutive moves to raise your combo multiplier.
- The game ends when none of the remaining pieces fits on the board.
About Cube Lines: Block Puzzle
Three pieces wait under the board. Pick one up, slide it onto the 8×8 grid and let go — a soft shadow shows exactly where it will land, and every row or column it would complete lights up in its color before you drop it. Fill a line and it bursts into confetti.
