Sega Master System / Mark III / Game Gear
Oh no! Funny-coloured jewels are falling into a box! Okay, so it's not the most exicting scenario ever, but this is a game of the "classic simplicity" type, such as Tetris and Klax.
The jewels descend in assorted blocks of three, the order of which can be changed as they fall down. When a minimum of three jewels of the same colour are placed together, horizontally, vertically, or diagonally, they disappear - and the jewels above fall down to fill the gaps.
It sounds rather dull, but Columns is the sort of game that you keep on coming back to time and time again because it's simple, playable and very addictive indeed. It starts off easy, but when you gel to high levels the jewels fall at very high speed, and your hand-to-eye co-ordination is given a really good work-out. A special mention must go to the sound, which is one of the best tunes heard on the Sega.
Columns might not be the most exciting game in the world, but it's a great way to unwind after you've just dispatched some big baddie with your lasers, or have kicked the heads of endless street gangs in the latest beat em up! Try if out - you'll be surprised at just how much fun it is!
