Print a card stacks. Some stacks have 28 cards, some 56 cards. Cut each page into 4 individual card. Distribute all card to the class or group. Each students may be given one card, two cards or several cards, but all cards must be distributed in order for the game to work properly.  This will mean that some students will have one more card than others.

Each card contains an answer followed by an unrelated question. One student begins by reading the question on his/her card. The student with the correct answer on a card replies, and then asks the question on that card. Another student replies etc. The card with the first question will end up having the last answer, and the game will come to a natural ending. 

Mix up and redistribute the cards. Time your students to see how quickly they can get through the stack, then challenge them to do it faster.
