How to play
- Move and rotate the active shape while it falls, using the next-piece preview to prepare the landing.
- Fill every cell across a row to clear it. Clearing multiple rows with one lock awards much more action score than a single row.
- Every five total lines raises the level and shortens the automatic drop interval, down to a 180-millisecond minimum.
- The run ends when the next piece cannot enter the board; the final screen combines action, line, time, and endurance bonuses.
