One player stands blindfolded in the centre of the room. The other players stand in a circle or a line. The players then switch places in the circle and one leaves the room. The blindfolded player should then be spun around and then have their blindfold removed. They now have one minute to name the missing player. If the player guesses right the person who left is blindfolded otherwise the blindfolded player is blindfolded again and has another go.
