This is an arcade puzzle game, where the player moves pieces horizontally within their current row. After each move, the whole board shifts upward, and a new row of random blocks appears from the bottom, with its layout shown in advance as a preview. When a row becomes completely filled, it is cleared and the player earns points. Gravity also affects the pieces: if there is empty space below a piece, it falls down. The goal is to move pieces strategically, complete lines, and prevent the board from overflowing.
