A golden-hour railway dice roguelike. Your locomotive hauls a stack of cargo crates, every crate holds a die, and those dice are both your health and your attack — lose a crate, lose a die. Haul-offs against rival engines resolve in tumbling dice rolls where the sum is your damage, holding dice to reroll the rest is the push-your-luck dial, and rolling exactly 13 wakes the Rail Jinx, a soot-sprite who takes his cut out of your hull. Thirteen stops up the line — seven duels, six depot drafts of lanterns, plating, and crew — to the Baron at the summit, whose own 13s hit you for 13 instead. Roguelite runs of 10-16 minutes, three unlockable engines, and a seeded Daily Haul where everyone rides the same line, with a leaderboard and streaks.
