Lumines II uses the same core gameplay of its predecessor Lumines: Puzzle Fusion with new features included.[2] The objective is to move, rotate, and drop blocks to form 2×2 squares or larger of the same color (referred to as a colored square). A vertical line known as the Time Line sweeps across the field from left to right and erases the colored squares; awarding points to the player's overall score. Erasing four or more squares will add a bonus multiplier to the player's overall score. Players lose when the blocks reach the top of the board.[3]
