How to Join Friends (Room Codes)

Dumb Ways to Build is online co-op for up to 4 players across Steam, PS5 and Xbox with cross-platform support. Room codes are real: PlaySide's official v1.3 patch notes call out "improvements to Room Code generation" — so lobbies are joined via room codes, exactly as players report. What PlaySide has not documented is the exact menu flow; the reliable route on every platform: add your friends on the platform itself (Steam / PSN / Xbox network), launch the game, and use the in-game multiplayer or friends flow from there.

• Be friends on the platform first — Steam, PSN or Xbox network
• Everyone updates to the same game version before connecting
• Use the in-game multiplayer menu — PlaySide hasn't documented the exact screens
• Cross-platform friends work too (official Cross-Platform Multiplayer tag)
• If a session fails, re-check versions first — patch timing differs per store

Searches for "Dumb Ways to Build room codes" usually land here, so here's the evidence-based answer: room codes exist and are the way you join friends — PlaySide's official v1.3 patch notes (dumbwaystodie.com) list "improvements to Room Code generation to eliminate region-specific character issues" among the fixes. The mechanism is officially real. What remains undocumented is the exact menu flow to create and enter a code, so this page won't fabricate screen-by-screen steps.

• Official: v1.3 patch notes mention "Room Code generation" improvements
• Room codes are how friends join each other's lobbies (per official patch notes + player reports)
• One practical tip from the patch: keep game versions in sync — patches have fixed code-related connection issues
• Platform friends lists and invites remain the reliable fallback route
• Exact menu steps will be added here once PlaySide documents them or the community verifies the flow

• Divide the two classic tools: one Nail Gun builder, one Sledgehammer for demolition — or add Update 2.0 tools (Caulk Launcher for foam platforms, Blow-Vac for relocating crew).
• Use the expanded ping system — Update 2.0 added 6 new ping options for coordinating structures and warning buddies.
• Watch each other: Restroom Rescue needs 3 revives with one Portaloo, so someone must stay down-able.
• Living Legend needs you to be the ONLY survivor — co-op trophies make great deliberate challenges.
• The co-op trophies (Restroom Rescue, Living Legend) need planning — they conflict with zero-death runs.
