Quadrafall — how to play
Simple rules — the game also teaches you as you play.
- Four-cell pieces fall from the top. Move them left and right and rotate them.
- Complete a full row — it clears and scores points. Clear several rows at once for more.
- Pieces fall faster and faster. The game ends when the stack reaches the top.
- The ghost shows where a piece will land. You can hold one piece in reserve.
- Modes: Marathon for a high score, Sprint — 40 lines against the clock, Zen — no rush and no game over.
