A falling block game similar to Columns , the objective is to create a horizontal or vertical line of three or more blocks of the same color, which will then disappear. The remaining blocks will fall down, but won't disappear if they form another line. Every 10,000 points a special block will appear, known as the Acid Drop , which removes three columns of blocks and marks the beginning of the next level.
Gameplay involves tilting the control stick to rotate the falling blocks into position, with the goal of clearing lines without letting them reach the bottom of the screen. The game requires strategy and timing, as players must anticipate the movement of the blocks to maximize their score.
