In this nocturnal game of chase, a flashing light is the clue to catching an elusive quarry.
Have the firefly alternate flashing the light with chirping. To find her, the other players will have to listen as well as watch.
Once it's dark, give a chosen player (the firefly) a flashlight and have her head away from the group with the light off, silently counting to 60 as she goes.
When the firefly reaches 60, she must flash the light once.
The rest of the players then count to 100 before setting out in pursuit of the firefly, who tries to avoid capture by hiding and changing directions.
But here's the catch: she must continuously count to 60, flashing the light each time she reaches the end of her count.
The first person to tag the firefly takes her place for the next round.
