Cart Surfer was a Club Penguinminigame that could be played in the Mine. The main objective of the game was the performance of various tricks and stunts to earn points (similar to Catchin' Waves) while riding a Mine Cart on a track. When players finished the game, they were brought to the Mine Shack.
This was one of the most popular games in Club Penguin, as it was a quick and consistent way to earn a decent amount of coins by using the most optimal moves (see table below). In Club Penguin: Elite Penguin Force, an adaption of this game for the DS appears, which can be played with either the D-pad and buttons or touch screen. It has more obstacles than the online version, and features an extreme mode as well.
The most efficient way to get coins on Cart Surfer was to alternate the Flip and Spin, Handstand or Run on Tracks: a 100 scoring stunt and any of the 80 scoring ones. Cart Grind was the highest scoring stunt for the turns. It also helped to crash a few times near the end, which gave the player more time to do tricks.
When a player lost a life, they got the chance to perform about 2–3 moves before the next turn so they had to use their lives wisely and could get an extra 540–840 points. Note that if a trick was performed twice or more in a row, the points it would yield normally were halved, until a different trick was performed.
An efficient player could earn approximately 450 coins per game. If a player had all the stamps for the game, their coins would be doubled, giving them 900 coins.
The prototype version of it was called Cave Runner.
Sometimes a Black Puffle would briefly appear even if you did not have one with you, along with your penguin turning to yellow (however, it did not happen if your penguin was yellow). This glitch was never fixed.
At one time, you were able to earn more than the maximum amount of stamps available on Cart Surfer, presumably due to a removed stamp. When you completed a game, it would display as "13/12" stamps. This glitch was never fixed.
When grinding around corners, you could extend a grind for much longer than usual. If you kept grinding after the initial "tipping" animation began playing, the cart would right itself again, allowing you to continue grinding. This only worked on or just after corners, and required careful timing, but allowed you to get upwards of 90 points on a single grind. This was a very efficient method of earning coins.
