Sudoku
Sudoku is a simple numbers game that has become very popular with newspapers lately.

Leap Frog
This is a slight variation to the well-known Leap Frog game. Click on each "Felix the Cat" to
move. The aim is for the cats to switch positions. Each cat can only move in the direction that
it's facing and cannot jump more than one other cat at a time.
