Time trials in Dumb Ways to Build

Every Job has a time trial Certification: one lap, as fast as your build skill allows.

Last verified: 2026-10-21 · build 1.2.70 · Requirements from platform data; reward from a launch stream. Best times are not officially listed anywhere.

Note: Express Check Out links to its Job's guide page for now (Hotel Hapless); a per-trial page was skipped over in favor of this hub — three thin pages would repeat each other.

How time trials work

  • A time trial is a replay prescription of a Job you already finished — the platform requirements tie each to its base Job.
  • The Mogging emote is publicly attached to the Hotel Hapless time trial as a launch-stream cosmetic read-out — the only named reward we can cite.
  • Leaderboard style timing, medal thresholds and cut-off builds are not published; we do not print invented target times.

Community-level route notes

Fast laps revolve around the finished-build knowledge: knowing the piece inventory in advance lets servers pre-build some path segments. Crews run time trials in co-op because extra Beans mean extra hands on the nail gun, but the session mode is your choice. Solo pacing differs per Job; no published meta exists.
