I love Tetris but as regular readers of my reviews will know, I'm always moaning about the lack of originality when it comes to developers who clone the formula to make block-building mobile games.
Finally, I've come across a puzzler that extends the format of the game beyond the realms of the original. Quick's SameGame takes a more mathematical approach, and scoring is based around the formula n^2 - 3n+4, so you need to be a bit sharper than you do in those games where you just match up the colours of blocks.
In fact, as the developer points out, you never actually 'win' in this game, merely try to beat your best score and head to the top of the leaderboard. Getting those big scores isn't easy and is made more difficult by the fact that every time you remove a group of chips, the gap is filled in, hampering the formation of new groups.
In terms of its graphics and presentation, SameGame is as basic as they come, but then, if you're the kind of intellectual type who would enjoy this game, then this is probably immaterial to you.
It doesn't look great but this one will certainly test your brain power.
