Makes your brain tired, this one. It's pure puzzling - there's no need to avoid nasties, just sort out the piles of coloured bricks rolling speedily towards you - it's vaguely reminiscent of a runaway roller coaster at Blackpool Pleasure Beach. Except without the screaming kids sticking ice cream up their noses.

The blocks zoom along a conveyor belt to fall into a deep well at the end. Pile the blocks up so the colours match up in a row of three or more to make them implode on the spot and whack up your score at the same time. Totally enjoyable, completely addictive and so fast your eyes might pop. Buy this fab coloured-tile-pile-'em-up before the axial tilt of the world shifts and the resulting magnetic turbulence wipes the data off every cassette in existence.
