Picture of MemAxe - 8Bit sound effects memory game
This is Instructable contains all the information and source code you need to build a fully functional MemAxe.

What is MemAxe?
MemAxe is an electronic game that tests your memory by making you copy a sequence of sounds using switches. The sounds emulate those of old 8-bit game consoles.

If you want to buy a kit with all the parts needed for this project including pre-programmed Picaxe, check this link out -> http://www.gadgetgangster.com/135

What does MemAxe do?
In the first round it plays one of 4 different sounds at random. Each sound represents a different switch on the device. After the sound is played you get a turn to copy the original sound by pressing a switch. If you get the sound right, MemAxe will play two sounds in the next round and so on. The limit is about 80 rounds.
