One player is blindfolded, making sure they can"t peek down their nose. Then a number of buttons and coins (or similar objects) are spread over the floor of the play area. The blindfolded players is then spun around and has a minute to find as many of the buttons/coins/etc as they can. The number of the items they picked up are counted and then they are returned to the floor. Once eveyone has had a go, the player with the most collected items is the winner.
