(Materials:Playing board with 2 large intersecting circlesSet of instrument cardsAttribute cardsAttribute listObject:To guess what attribute the circles representPlay: Leader selects 2 attributes from the cards and imagines the 2circles as the corresponding attributes.Each of the players in turn picks up an instrument card and handsit to the leader who places it in the appropriate area on the playingboard. There are 4 areas that an instrument can be placed: inthe space shared by both circles, in the part of each circle notsILared by tILe other, or outside the circles.Example of play if A is "large"and B is "$tring"Player 1 selects guitar soit is placed within "string"Player 2 selects tuba, andit's placed in "large"(Player 3 picks clarinet,which is neither attribute,so it's placed outside.Player 4 picks cello withboth attributes, so it'splaced in their intersection.Play continues until there are enough instruments in place fOr oneof the players to guess at the two attributes. One can guess onlyafter his instrument card has been put down and he must give bothcircles correctly. If the guess is correct, he receives as manypoints as there are instrument cards left on the table. If theguess is not correct, he subtracts 5 points from his score. A timelimit or point limit can end the play. The winner after that limitcan be the next leader.282Extensions:1. Add more instrument cards2. Add another circle (andtherefore another attribute)3. Add negation of attributesto deck of attribute cards,ex: not brass, not large(
