Cart Surfer is a minigame that can be played in the Mine. The main objective of the game is the performance of various tricks and stunts to earn points (similar to Catchin' Waves) while riding a mine cart on a track. When players finish the game, they return to the Mine.
On January 24, 2018, the game was given a redesign with a new hardcore mode and a leaderboard added to the game.
The goal of Cart Surfer is to earn as many points as possible in a certain amount of time by doing tricks in a mine cart. All of the different tricks give a varying amount of points, ranging from 10 points from turning and 100 points from performing a sick flip. Doing the same trick twice will halve the points earned and the points received from doing the same trick will stay as that amount unless a different trick is performed.
The player has 3 lives and the game ends when all lives are lost or when the light of the tunnel is reached. They can also bring a black puffle along, which may help you recover from a wobble.
