A fun game which requires no equipment and is v popular with my kids is 21. So basically you count around the table or room starting at 1. Each person can say 1,2 or 3 numbers. The person who says 21 is out.
So I might say 1,2 then R 4,5 then V 6 then MrS 7,8,9 and so on. Usually we conspire to get V out because the always tries to cheat at games
