In Marble++ the object is to collect the balls off the table. To do this, you select a ball, then hit it towards another of the same colour. A glowing sensation will overcome the balls which touched and they will be removed from play. The game records your fastest clearance speeds.

Initially a very simple game, the easy mode allows you to collect balls in a random fashion. The second mode introduces spikes - one touch means instant disqualification. Hard mode gives more spikes and less manoeuvring room. Successfully beating out all three modes gives you an editor.

The editor really makes the game shine. The ability to select how many balls, how many spikes and how many coloured different balls are on the screen in an exceptionally nice touch. Coupled with the minimalist graphics and sound design, this is a very accessible puzzle game.
