The rules are really basic : click on the left, right, upper, or lower part of the screen (or press the direction pad) to have all the blocks who can move in that direction... If you form groups of 3 or more blocks, they'll disappear, etc...

To get huge scores, trying doing combos, not leaving a single round before exploding another group, etc... Easier said than done !

Decent, fun game. Not very complex, gameplay is very, very simple, and difficult to grasp at first, but once you get the hang of it you can rack up some serious points. The only thing I didn't like was the scoring system, which is cryptic. Sometimes I get more points for making less blocks disappear, and less for making more disappear. I'm sure there's a system behind this but I don't see it. Overall a good download, something fun to pass the time.

Awesome game that works both with hardware buttons or touch screen. Great for the bus, hard to put down tho.
