Menko Rules

Ohtani-san says...

Menko cards are primarily for a game in which kids throw their cards to flip their opponent's one which is placed on the ground; if they succeed, they can get it.( It is very similar to POGs)  And "Gu-Choki-Pa" marks are for a sort of optional game, played as rock-scissors-paper.  Kids take out one of their menko to compare with their opponent's simultaneously by signal; and if they win, they can get his or her menko.  Playing with "Fighting Numbers" is the same; trying to outnumber the opponent's menko.
