Zenerchi

If you like the match 3 sort of games, and want something a little different, then this is a blast.

Its based on spinning wheels, to  match the 3 or more coloured tiles, and then dump them out through a central reserve for points. There are blocking tiles, and holding tiles, and energy balls that link two wheels together. If you match 5 you get a powertile, which can be saved for extra points at the tally up, or you can double click it to take out its surrounding tiles. Useful for ridding yourself of troublesome blockers.

It has a fairly slow intro tutorial to get you into the swing of it, and it runs two modes a timed mission/level based one, and a zen mode which just lets you continue until you attain the victory condition. It seems overly simple to begin with and you wonder whether its almost too simple and perhaps dull.. but when you start to understand the tricks and lining up strategies it soon becomes addictive and you'll find your 60 minutes of trial time sucked away..
