Pick one player plays Simon and give directions for other players to follow, such as:
“Simon says jump”
“Simon says leap into the water”
“Simon says swim in front crawl”
“Simon says get an inflatable and swim around a minute”
If a direction is given without “Simon Says.” and the player follows this direction, the player doing so is out. If someone does not obey a Simon Says Direction, they are also out.
The player that remains the longest becomes the next one to be Simon.
