Day route board
Pick the next safe action before the raft drifts too far
Treat each stop as a short route decision: hook what is close, stabilize the raft, feed the bonfire, cook food, then leave only for island supplies the raft can bring home.
Use a Crab Trap only if the current build menu shows it; otherwise keep the food route short
Use raft route when island timing gets risky
Use a Pump Jack only if the current menu shows it, then follow the live prompt; otherwise shorten the route
Wiki
The useful loop is supply gathering, harpoon pulls, raft building, island exploration, weapon finding, bonfire progress, cooking, and day survival milestones.
SurvivalSurvive by turning the starter beach into a working raft route first. Feed loose scrap into the grinder, craft the raft, use the old sack for return trips, secure food, then expand only when fuel and storage are under control.
Crab TrapCrab Trap visibility was observed in the build menu, but recipes and collection behavior can change. Read the current menu and collect only when the live game shows an interaction prompt.
Pump JackCheck the current build menu for Pump Jack, follow only the current in-game prompt, and collect only when a current prompt appears. If the menu, prompt, or output is absent, return to the normal fuel route instead of waiting on an assumed timer. No exact unlock requirement or production timer is published here.
CompanionsOpen the current Companion panel and read the live shop text before using Pearls. Compare only the roles shown there, then decide whether the current run needs a Class or Companion choice.
Boat UpgradesUpgrade the raft around the pressure ending the run: structure and storage first, then check the current build menu before relying on Sawmill, Crab Trap, Map Radar, defenses, or later support.
Raft RouteRoute your run in bands: grind and craft the raft early, stabilize storage and food by day 10, make day 20 trips solve one problem, make day 50 trips protect supplies, and treat day 100 as a rescue push.
CodesNo working code is listed here right now. Open the in-game menu once before a long run, then return to gathering, cooking, fuel, and raft upgrades.
