Cylindris

Complete the ring

Fill a whole ring around the cylinder to clear it. Keep stacking below the top. The board wraps all the way around, with no side walls.

Move, turn, drop

Move left or right to travel around the cylinder. Turn a piece to fit, then drop it onto its faint landing guide. Hold saves a piece for later, once per turn.

Use the bottom panel: arrows move, curved arrows turn, Down lowers a piece, and Drop places it instantly.

Find your rhythm

Classic has 10 columns; Colosseum has 16. Clear consecutive rings for combos, or four at once for a Cylindris. Every ten rings raises the level.
