Dumb Ways to Build 100% Completion Guide
What “100%” means in Dumb Ways to Build, kept honest: a verified checklist plus a separate Still Unverified block.
Verified completion checklist
- Complete every Crisis Job — including Hotel Hapless, Drain Strain and Crane Climb.
- Earn the Master Builder Certification — see the guide.
- Clear all Jobs in Master Builder — the challenge variants.
- Unlock all 25 Steam achievements — achievement hub.
- Find all seven secret achievements — the secrets list.
- Collect certifications and cosmetics — official materials tie Certifications to cosmetic unlocks.
Still unverified
A few things are not yet confirmed by official sources or direct verification, so they stay on a watch list instead of the checklist:
- Whether every cosmetic/certification combination is guaranteed to be obtainable in one playthrough.
- Hidden Jobs or extra challenge modes beyond Master Builder variants — none are announced.
- Platform differences in trophy/achievement sets between Steam, PS5 and Xbox beyond the Steam 25-count baseline.
Suggested order
- Finish all Jobs at normal difficulty.
- Go for secret achievements while filling the achievement list.
- Replay Jobs in Master Builder for the certification and remaining cosmetics.
