I have tried killing all of my friends with a butter knife when i was the seeker and that was fun, but the mess that you have to clean up afterwards is just too hard. (Since i'm a lazy scum) So, what is the best game?
Well I found a guy who's amazing at it because he managed to stay hidden for two hours after the 2nd to last person was found, and that was because he revealed himself.
If possible set up traps involving water. Everywhere. If not then sneak a few water balloons before going. See how many people end up wet during the hide and seek game.
If you wish to prank everyone in forest hide and seek I recommend you research the most dangerous animal around you and get some recordings of it to play and play them loud and scream and see how many people either run away or run to try and help you.
