Nothing, repeat nothing has frustrated me more than the famous \'Rubik\'s Cube\', rotating each of the layers in the classic 3 x 3 x 3 coloured cube. At one point I\'d worked out how to do it - in 10 minutes, only to find videos of people solving the cube in 20 seconds. xCube threatens to bring the same gameplay - and frustrations - to your iPhone. Whether this is good or bad is, of course, dependent on your point of view and state of mind!

Before going any further, it should be noted that the classic 3 x 3 x 3 cube is NOT included here, for legal reasons, a great shame. However, any existing spatial skills from the real cube are still useful, since much the same general techniques are needed here, solving 2 x 2 x 2, 4 x 4 x 4, 5 x 5 x 5 and 6 x 6 x 6 cubes. Oddly, each cube starts fully solved by default, leaving it to you to 'mess up' and then solve. This oddity becomes a little clearer when you flick the 'Timed' switch on and watch the cube become far more scrambled than if you'd been left to switch it around yourself.

Then it's into cube solving, with each layer easily draggable using the touchscreen. You can even rotate the whole cube using the iPhone's multi-touch by using two fingers to drag - it's a very intuitive 3D system. Using 'Settings', you can customise the game to suit your preferences, with replacement cube face 'stickers' and replacement background themes.

xCube continues its mature interface with unlimited undo and redo of moves (using the arrow icons at the top of the screen) and with full saving of each game state when your game session gets interrupted. The lack of the classic 3 x 3 x 3 cube is very disappointing, but perhaps enough people will buy xCube to enable to developers to pay Mr Rubik and his lawyers the appropriate license fee? I do hope so, this is otherwise a beautifully put together little game.
