<P> One person is "it" and a can is placed in an open space . The other players run off and hide, then it tries to find and tag each of them . Tagged players are sent to jail . Any player who has not been caught can kick the can, setting the other players free from jail . </P> <P> Laser tag is similar to flashlight tag, but using special equipment to avoid the inevitable arguments that arise about whether one was actually tagged . Players carry guns that emit beams of light and wear electronic equipment that can detect the beams and register being hit . The equipment often has built - in scoring systems and various penalties for taking hits . Pay - per - game laser tag facilities are common in North America . </P> <P> An aquatic American variant of blind man's bluff, most commonly played in a swimming pool, although it may also be played while swimming in shallow natural bodies of water (typically the areas near the shores of oceans, seas, and lakes). The players may be swimming, treading water, or walking on the bottom of the pool or body of water . The person designated "it" is required to close their eyes, and shouts "Marco!" at regular intervals; the other players must shout "Polo!" in response . "It" must use sound localization to find one of the other players and tag them . The tagged player then generally becomes "it," and the process repeats . </P> <P> Muckle (sometimes called "muckle the man with the ball", "kill - the - guy - with - the - ball", "kill the carrier", among other names) is the reverse of regular tag; all of the other players chase "it". This player is denoted by carrying a ball (usually a football). When they are caught, they are tackled, or "muckled". Whoever retrieves the ball first or whoever attacks the one who is it then becomes it . Sometimes the last player arriving to tackle the former ball carrier is the next person to be it; in other variations the player with the ball throws the ball up in the air, where it is caught by another player who becomes it . </P>
