You must have at least 12 players in the game of blind bats trying to get out of a cave. The players are divided into two groups, one group representing the bats and the other group representing the cave of the bats.
The bats are gathered together and blindfolded. The other players form a circle around the bats; this circle is the cave. The players forming the cave should not stand too close to each other; there should be enough space between two people standing next to each other for a bat to pass through easily. When the game starts, the bats try to get out of the cave. Blind bats use sounds for this purpose. Each of the players in the cave rubs their hands together to show their position. If the bats can leave the cave without touching the walls of the cave, i.e. the other players, they are free; if not, they return to the cave. The game ends when all bats are free.
