Tetris is widely regarded as *the* addictive computer game. It's available on almost every popular format imaginable, and it keeps thousands of people engrossed for hours on end. Not bad for something that originally came from Russia!
So it was only a matter of time before someone came up with a game along similar lines. Finnish software house Avesoft have produced Coloris, which differs from Tetris in one important aspect. For, instead of linking shapes together to form unbroken lines, the idea is to match colours to keep those blocks at bay and rack up the points. If the blocks reach the top of the playing area, then you lose and the game ends.
And, if you feel as though you're really soopa at linking those hues, you can try your hand at the time trial game which gives you a limited amount of time in which to score as much as possible.
Where Tetris is immediately playable, Coloris isn't as blantantly obvious and you need to read the manual before even attempting to get anywhere.
The colour-matching gives the game some originality (even though it is, in all other respects, a Tetris "clone") and, like that multi-format classic, is very addictive. Not quite as enjoyable as Tetris, but the ideal game for the 0.02%
of the population who want a puzzle game which is a bit more complex.
