Playing Instructions: Remove as many marbles as possible from the board. The only legal moves are horizontal or vertical jumps of one marble over another to an empty hole on the other side. The marble that is jumped is removed from the board. To move, just drag a marble in some legal direction.

Playing Instructions: The objective of the game is to turn all 25 "lights" on. Clicking a square will toggle its light (as well as the lights of all horizontally and vertically adjacent squares) on and off.

Try to solve the rolling cubes puzzle! You start with eight cubes around a center hole. Each cube is black on the top and white on the bottom. The object is to roll the cubes around until the cubes are in the start position but with the white faces on top. Click on a cube to roll it.

It is possible to win in 36 moves. Good luck! Solving the puzzle is harder than it looks.
