This is a memory game kit, similar to the Simon games. It starts out slow and speeds up as you reach each level. The first level is completed at 5 in the sequence, the 2nd at 12 and the third at 21. When each level is completed, it rewards you with a different sound effect. The Led's are the same color as the original Simon game: red, yellow, green and blue. When you lose, the game flashes out your score, indicating how far you got in the sequence. Easy to assemble if you are familiar with soldering. 3 AAA batteries are required to complete the kit.  Flat rate shipping if you buy more than one.
