In classic game you should move falling cube with stylet or motion to connect right side to left. You can downgrade once a selected cube with down or B key. Make combo (multiplicate points) with followed lines.

In puzzle game move cubes vertically with stylet (no motion supported). Downgrade a selected cube by down or B and add a new line with L or R key.

The ten best scores are saved for each game and each level/time.
