Two teams of two players each start at the corners of a square play area with cardboard boxes scattered throughout it.
Each player starts in a different corner, armed with a flashlight. Turns alternate between players, from one team to the other. On a player’s turn, they may take one step in any direction, and may also choose to turn on their flashlight. Once they turn on their flashlight, they cannot move it at all, and it is turned off on their next turn. Players cannot move at all if it is not their turn, but teammates can try to position their bodies to cast their own shadows too!
To win the game, catch both members of the opposing team standing in the light. Players are only “safe” if both of their feet are standing within the shadows.
