The goal of the game is to tap when your square is inside of the ring. You have 3 hops (represented by the stacked numbered rectangles in the center) to try to get to and tap while inside the ring.
As well as getting a point, you also get 1/27th of a crate, and you can open crates for gems which you can use to buy more gradients!
Overall a very simple and relaxing game to play when you are bored :)
Good Luck and Have Fun!
