Some people are really puzzled by puzzle games. "What's the point?" they say: "with all that technology at my disposal, I want fast, colourful, all-action gameplay, not something that would work just as well on the ZX80!" To an extent, those people (Mr. & Mrs. Richards of Solihull, John Townsend of Fife, you know who you are!) are right. A lot of puzzlers on home computers are just games that are available in paper and plastic from your local toy shop, re-arranged so that a computer opponent can take the place of a brother or school chum.
On the other hand, there are some puzzle games that were designed specifically for computers. Games that could quite comfortably spend the night with words like 'fast', 'colourful', and 'all-action'. Tetris is one, and this baby Klax is another.
Chances are you know what this game is about anyway. For those that don't, here's a minimalist explanation: coloured blocks - bat - collect blocks on bat - move bat - drop blocks - blocks match blocks disappear - points - enough matches next level - blocks reach top lose life.
It's a hectic game, which many people rate higher than (the more tactical) Tetris, and there's far worse things you could do with your time (washing up).
