Building Tips Guide - Stability

The three rules of stable building in Dumb Ways to Build: (1) Build wide — two-plank-wide bridges are dramatically more stable than single planks. (2) Double-nail critical joints — especially in Crisis and Master Builder where hazard pressure can break single nails. (3) Use triangular supports — triangles distribute force better than rectangles and resist collapse longer.

• Wider is more stable. In a physics sandbox, a narrow tightrope path is the first thing to fail.
• Fasten load-bearing points properly — the Nailed It and Screw Loose trophies (100 nailed, 100 unnailed) confirm revising structures is normal play.
• Test before committing — walk your structure before sending the whole crew across.
• Build from your side outward — never leap-frog across gaps.
• If a structure creaks, sags or shakes, treat it as feedback and reinforce or widen it.

The most frequent mistakes new players make: building narrow paths (they fail under any real weight), forgetting to fasten joints (loose pieces slide), and over-building — more material means more weight, and weight causes sag. The sweet spot is the minimum viable structure, properly fastened.

• Single-plank paths — always build at least two planks wide for stability
• Missing nails — an un-nailed joint is a falling joint; nail every connection
• Over-building — more planks ≠ more stability; extra weight causes sag
• Ignoring physics feedback — if a structure creaks or shakes, it needs reinforcement
• Not testing before committing — walk your structure before crossing it fully

Time Trials reward speed over elegance. The minimum viable path is always the fastest: build exactly what you need to reach the objective, nothing more. Skip decorative supports, use the Nail Gun exclusively (no tool swaps), and memorize the optimal path through repeated attempts.

The two confirmed tools divide co-op labor naturally: a Nail Gun builder pushes construction forward while a Sledgehammer partner handles demolition. Proximity Chat — an official feature — is how you coordinate, "or just listen to the ensuing carnage". Roles are not officially prescribed; this split just covers both halves of the build loop.

The confirmed challenge layers reward different habits. First clears reward careful, well-fastened building. Time Trials reward the minimum viable path. Master Builder Mode — the rarest clears at 5.4%, 2.6% and 0.8% — demands everything at once. Zero-death runs reward patience above all: scout, build slow, test everything.
