Each player receives: 1 framework, 1 board and 18 pins. According to which side of the board one plays, (one side features numbers while the other side features pictures) either numbers or pictures are called.

Alternately each player calls a picture. One player marks the picture, which another player said out loud, with a pin.
Players cannot put a pin in a picture that has already been pinned by another player. You have to remember which pictures have been pinned.
Whoever calls a previously marked picture from a fellow player, loses.
