Have you ever sat with a blank mind before a game of Solitaire, simply clicking away while the brain idles? Some folk need concentration to play - I found it a good way to clear the head!

BUT, having said that - there is one game I love online, which takes concentration, quick thinking and (preferably) a good internet speed. InkLink at Shockwave - online pictionary! With a good vocabulary, mouse-drawing skills and decent typing speed, you can come out tops. Once you start, expect to spend a few hours at it too.

At the same site is Bejeweled2, which is fun in a mindless sort of way - and hilarious when the Big Voice kicks in at the start of levels. My son and I got on it (on seperate computers) last night - but couldn't get beyond Level 8.

Bored? Go give them a try.
