This is a relatively simple game. At least 3 players are needed, although the more, the merrier. First, select the "it" or the defender. Next, find a can, or something that can be knocked over easily from a distance. Position this can in the center of the game area (this will be it's home plate or base). The game is played as follows.
The "it" will defend the can from being knocked down. While it is in the upright position, the "it" can chase anyone and tag him/her. When a player is tagged, and the can is still in the upright position, that player becomes the new "it".
The rest of the players must then see to it that the can is always knocked down. The "it" of course can always put it back in the upright position. The rest of the players usually use their slippers to knock the can from a distance. Or if one gets close enough to the can without getting tagged, he can kick it and pick-up the rest of the "weapons" or slippers used. Of course, it is usually up to the other players to get their own "weapons" or slippers. For fairness, it would be nice if the players had only two slippers to knock down the can, no more than that. Once all the players are out of slippers, this would be a major opportunity for the "it" to chase everyone before the can is kicked. The can has to be positioned in a particular area of responsibility.
