Players rotate falling pieces in a grid-like layout to clear as many lines as possible before they reach the top. The pieces are made up of various shapes, each composed of four blocks.
The core mechanic involves rearranging the falling pieces by rotating and moving them left or right. As the player adjusts the shape, they must clear entire lines in order to progress and avoid letting the pieces accumulate and pile up at the top. The player must solve these puzzles efficiently to manage the pace of the falling pieces.
The objective remains to clear as many lines as possible without the pieces reaching the top of the grid. The game takes place entirely within a web browser, requiring no download or registration to play.
