COURSES
Every course here has been beaten by the solver before it was allowed to exist: a player’s
course is published only with a winning run, and our server replays that run before anyone else sees it.
Nothing unbeatable ever reaches you.
PIECES0 / 14
Pick a piece, then tap the course to drop it in. Drag a piece to move it, tap it to get its knob,
and ↶ takes back any change.
The solver re-runs after every change and will not let you publish something nobody can beat.
RESEARCH
Research costs bolts, which are only ever earned by playing. The wait is the
other half: clearing courses and finishing jobs takes time off for free, and cores finish a research at once.
CRATES & SKINS
Hazard Crate
One piece you don’t own yet
ODDS: EVERY PIECE YOU DON’T OWN YET IS EQUALLY LIKELY
RUNNER SKINSYOUR RUNNER
Your runner wears its skin in every run you play. Skins change how your runner looks,
never how it plays.
UPGRADE BENCH: SPEND CORES, NOT BOLTS
A piece’s level caps how far its knob goes. At level 1 you reach 40% of the
range; at level 5, all of it, and the Fine Tuning research adds one more step to every
piece. Everyone attempting your course meets the same trap,
so a stronger saw makes your courses nastier without ever making your runner better
than theirs.
