100 Days at Sea Survival Strategy

This strategy page is for players who understand the basics and want a safer decision model for longer runs.

HomeGuide hub

Control risk first

Longer survival comes from reducing surprise. Before each route, decide what can go wrong and what you will do if supplies run low.

  • Prefer repeatable routes until a new area is scouted.
  • Keep a fallback plan for low supplies or unexpected hazards.
  • Use the calculator when you need a quick risk-level check.

Upgrade around your failure point

The best upgrade is not always the rarest. It is the one that fixes why your run ended.

  • Choose safety if early runs fail before reaching your target.
  • Choose route efficiency when you can survive but progress slowly.
  • Delay luxury choices until your survival loop is stable.

Use updates as strategy checkpoints

When an update changes regions, rewards, or code demand, old strategy can become stale.

  • Check the update hub before following old routes.
  • Treat new named regions as scouting content until details are verified.
  • Refresh internal links from the guide hub after major changes.
