-Treasure hunting (A person goes hide somewhere in a zone, the first 3 to find him get respective treasures)
-Rat Races (Get from point A to B to C as fast as possible)
-Noggenfogger Roullete (Jump from a high place with 1 noggenfogger in inventory, the survivor wins a price)
-Mountain Climbing (Self-explicatory)
-Tag (Group A hunts Group B with the thing you can thrown so they catch it)
-Rare hunting (Start from central point, the first to kill a rare spawn wins)
-Deadmines race (Get in seperate groups, first one out the other side wins)
