Mosquito is a game played in groups of four players. At least one of them has to move a lot during the game!
You don't need any equipment for this game.
One player is selected to be the mosquito. The other three players are standing in a circle, facing each other. They hold each other's hands. One of them is defined to be the target, that the mosquito has to try and bite. The group of three has to prevent this. They may not use brute force, but can only try and turn away. So, in fact, the two players that are not the target have to try and get in the way of the mosquito, to prevent the target from being bitten.
