Pieces descend into a vertical well, and the player positions and rotates them to build complete horizontal lines. Completed lines disappear, creating room for additional pieces and increasing the score.

The objective is to continue clearing lines without allowing the stack to reach the top of the playfield. Progression is based on sustained survival and scoring; no distinct characters or narrative campaign are documented.

Keep the stack low and avoid creating unnecessary gaps. A nearly level surface gives more options for future pieces and makes recovery easier after an awkward drop.

Reserve narrow spaces for pieces that fit them naturally, and rotate pieces before they reach the lower part of the well. When the stack becomes high, prioritize immediate line clears over building a valuable but risky setup.
