One Cub is the Queen (or King) of Hearts.

The other Cubs give instructions that the other Cubs must follow.  E.g. Do a cartwheel, jump 3 times.  The Cub must start instruction with "Queen of Hearts says..." .  If they don't, the Cubs must not follow the instruction.  Those that do is identified by the Queen by saying "Off with his/her head"

Winner gets to be Queen for next round.

Alternative:  queen can simply give instructions and if they shout "off with their heads", everyone has to run and the Cub that is on tries to catch someone who is then "on"
