Despite the strange name which makes it sound like some kind of anti-laxative, Ring Pass Not is another of these strangely addictive games. Once it's loaded you can, if you wish, click on "Options" and untick the "Music" checkbox to stop the annoying pseudo-medieval background tune.
The game is a puzzle which involves creating a ring by matching paired segments by their colour or shape. As you progress, constraints are applied which make this more difficult, although these can be offset by bonus tools which you accumulate for special arrangements or combinations of colours or shapes.
Yet another game. I don't go searching for these games, they come to me, honest! Anyway, this one is called Shuffle, and the object is to knock your (computer) opponents' (yellow) balls off the board before he removes your (red) balls. Sounds boring, but it is strangely addictive, and very easy to pick up.
This sort of thing fascinates me. It's a flash-based graphical presentation of the more recent theories on how the world was populated by humans. Starting from Africa 160,000 years ago, the various routes taken, successes, and setbacks are displayed.
These games are a horrendous waste of time, but intriguing and quite satisfying to play. I didn't realise that there were so many variants of this game. I personally have only played Desktop Tower Defence and Flash Element TD. It was Flash Element TD that got me started on these types of games.
