Parkour. A portal in the middle of the plaza takes you to a lobby with three courses behind three doors: easy, hard and hardcore. Reach the finish and you are paid in wheel spins.

Every course is a different shape, not the same one made tighter. The easy one runs straight, the hard one breaks into sharp turns you have to take mid-jump, and the hardcore one spirals back on itself for forty five obstacles.

Falling off a course puts you back at its start, not on your farm.

A wheel of fortune. Spend a spin, win a boost. Every slice is the size of its own chance, so the wheel you look at is the odds table.

Three kinds of boost, each with three strengths: mining speed, coins you pick up, and how fast the exchange gets through your hashes.

Boosts do not replace each other. A 1.25 and a 1.5 of the same kind both run, each on its own five minute timer, and their bonuses add up to 1.75. Winning the same one again extends that timer instead.

Each course rests after a run: ten minutes for easy, twenty for hard, thirty five for hardcore. The other two stay open while one rests.

Easy pays 1 spin, hard pays 3, hardcore pays 5.
