BrainBox is a fast and fun memory game that does not require any pens, pencils, paper, playing board or even a table! Each round takes 10 seconds so all players are involved. A game lasts as long as you want it to, 10 minutes is the norm, but playing for 5 minutes is great fun also. BrainBox is educational and is perfect for families and groups of friends to play, wherever they are, on a level-playing field.
