The Linux Memory Game is an X11 game using GTK+ library for children ages 3 and up. It is a lot more than the card game "Memory". It has five skill levels, the higher ones are challenging to adults as well. Additionally, one can choose from the menu to match 2 cards or 3 cards, or match different cards. This last "different card" mode can be a very good teaching tool for teaching languages, concepts, or association.
