Computer games.

I used to play this game called Fire Boy and Water Girl with my sister. It is only a 2 player game. It is set in a temple. You have to get past these little traps and to your door at the end. If you are fire you aim is to get to the end and go through the red door to pass the level. If you are water you have to get to the blue door at he end. You can only pass the level when both characters go through the door. The things that will kills you are..... There are little pits of fire or water that you have to jump across. If Fire Boy jumps in the water pit he will die and the level will have to start over.  It is the same with Water Girl.
There is about 3 different games with different levels.
I really liked this game because it is challenging and really fun!
