The player is tasked with keeping a white ball (called "The Vessel") on the road for as long as possible without falling off. The road has procedurally generated twists, turns and dives and is endless. The player controls the ball by tapping (with two fingers)[4] left or right on the screen.

Each time the player passes a numbered checkpoint line, the player gains a point (several if they missed some checkpoints in between). The player can "cheat" and fall off the road and land on a road section further on the road.

When the player dies (after several seconds of free fall), the player is presented with the option to play again. The player can see how many checkpoint lines they crossed and how many they skipped.
