Coal Cart: Checkpoint Run
Ride a minecart down through a coal mine, an ironworks, and a cotton mill. Every few seconds a checkpoint question appears at the top of the screen and a gate of three answer banners rises over the rails, switch onto the track with the right answer. Right answers earn power-ups; wrong ones cost a strike and show you the real answer.
Switch tracks← →hop one track per press (A/D, or swipe/tap on touch). SPACEstart, or pause during a run. The cart rolls itself and picks up speed the longer you last.
Pick your trackRead the question, then be on the left, middle, or right track as you pass the gate.
Dodge & collectSwitch around rockfalls, powder kegs, and parked ore carts, and the odd cart rolling ahead of you; grab trails of gold as they hop tracks. Pickups: shield, ×2, coin magnet, and the uncommon steam jump (10s blasted up over the rails: no hazards, no gates). Correct answers also earn a power-up; three in a row = a guaranteed shield.
3 strikes · 2 bumpsA wrong gate costs a strike (−1 ♥); lose all three and your shift is over. Hitting something slows you down and leaves the cart damaged for 10s, hit another while damaged and you derail.
Tip: click the game first so the arrow keys switch tracks instead of scrolling the page.
