Slide down the longest waterslide in the world in the 3D multiplayer dot io game AquaPark.io! The slide is surprisingly crowded. Your objective is to reach the bottom of the slide first. Grab the speed boosters and avoid the walls. Watch out, because if you slip over the edge, you'll fall into the abyss. You can overtake other players, but you can shove them over the edges as well, which is more fun.
