Zi is tetris-like game, which is actually closer to meteos…

You can move the blocks around like in meteos. Once you have a set of 3 or more blocks, you can remove them by clicking on the set, kind of like in a JawBreaker game…

That’s the first thing… but there’s more : it has a sort of double-gravity : first 6 block series fall down, last 6 fall… up ^^

Original game from Alan Gordon
