If you guys are looking for an addicting game that will keep you busy for a while, may I suggest N+ for the Nintendo DS. This is a game where you are a Ninja and you must navigate through a maze of obstacles such as mines, lasers, homing missiles and other traps. The game is only $20 and it is available for the DS and PSP.....and even available for the 360 as Xbox Live Download (800 points)
This game will test you, you need to make precise jumps in order to complete your missions, and many of the boards have you navigate all the way to one side of the board to flip a switch for a door that is back where you started from. The first few puzzles will leave you with the impression this is a piece of cake, but be warned that the boards get increasingly hard to the point of you wishing you hadnt gotten addicted to this game. I believe there are 45 boards and each board has 4-5 levels.....so more then enough to keep you busy.
Oh and this game originally started out as a flash game on the internet, so if you want to give it a try.....go to the link below
