Job Type 3: Master Builder Mode

Master Builder Mode is the high-difficulty replay of each job, confirmed by the trophy list: Hotel Hapless, Drain Strain and Crane Climb each have a Master Builder clear worth a trophy. It is the closest thing Dumb Ways to Build has to an endgame — the ultra-rare completion rates (5.4%, 2.6%, 0.8%) tell you how far past the story this layer sits. Post-release updates also stage their new Certification tasks here — see Remodel the Break Room below.

All three Master Builder trophies are required for the platinum, alongside their sibling challenges on each job. Clear the standard job first, learn its hazard rhythm, then take on the mode.
