A sokoban game - you must move a cosmic sphere around a game board in outer space moving star blocks. It's trickier than it sounds and with 375 other bizarrely shaped levels, it gets trickier still. You'll need to be at least one step ahead of yourself throughout the game, as one wrong move and you'll find yourself stuck. Great 3D graphics run fast even on weak machines. Like all great puzzle games, it's easy to learn but difficult to master.
