Ends of the Earth Station

In Spirit Tracks, Ends of the Earth Station is located in the northeast corner of the Fire Realm.

Location
It can only be accessed after Link brings five Cuccos to Rael in the Sand Sanctuary. As a sign of gratitude, he will reward the young hero with a Force Gem that reveals the Spirit Tracks to the Ends of the Earth Station.

Features and Rules
In this station are three levels of intricate block puzzles, similar to ones seen in the Sand Temple, that require aid of the Sand Wand. The levels are Brainteaser, Braintwister, and Brainmasher Block Puzzles, with their names being a sort of "beginner, intermediate, and expert" indication, as each is more difficult than the last. Each level also contains three parts. After completing a level, Link will be rewarded with a treasure (with the second level yielding a Heart Container as a reward), and Princess Zelda will compliment his puzzle-solving skills. Moreover, the young hero can also obtain 100 Rupees after the completion of each level.

Trivia
In the European version, a small reference to A Link to the Past is made here: Brainteaser, Braintwister and Brainmasher puzzles each have a small inscription referencing to different swords of A Link to the Past. Brainteaser is said to be for Master Puzzlers (Master Sword), Braintwister for Tempered Puzzlers (Tempered Sword) and Brainmasher for Golden Puzzlers (Golden Sword).
