Shark tag was my fav game to play when I was younger Best with 4+ people How to play if you are a human: You try not to get tagged and you can stay on the ship (The playset) or you can go into the water (The ground) and you try not to get tagged. when you get tagged you have to let the former shark get on the playset.
How to play if you are a shark: you have to stay in the water (The ground) and your main goal is to tag someone else to make them the shark, way you can do that is going under and tagging their shoes or if they are in the water you tag them and you get a few sec to get onto the playset before the game starts again.
