Take on the role of Inspector Parker and tackle a murder mystery in an old English castle. Betrapped has a lot in common with Minesweeper, the idea being to uncover traps in each of the tiled rooms.

Another color matcher that is familiar to millions of Net gamers. If traditional Collapse is too slow for you, this game can be set to push bricks from both the top and bottom of the screen. When the frantic clicking starts to cramp your wrist, switch to strategy mode for a pleasant change of pace.
Color matching with a 3 dimensional twist. Cubis Gold 2 has 4 game modes but there isn't much difference between them, and the shooting dynamic is a little difficult to get used to. An editor is included so you can arrange your own puzzles.
