Quick answers
How to Fish map FAQ
How many main progression stages are in How to Fish?
Current guide consensus describes five main stages. This page tracks them in order and uses the first stage you have not marked complete as your current stage.
What are the five islands in order?
The working route is Lighthouse → Forest → Island 3 — Desert → Island 4 — Rocks → Volcano. Palm Trees and Casino Barn remain visible only as single-source guide aliases under verification; none is claimed as the official in-game name.
Why does this map not show exact directions or coordinates?
Direction reports vary and could depend on route context. The SVG is an original progression diagram, not a geographic copy of the game world.
Where is the Radar X marker?
Official patch 1.0.10 information says the confusing X marker was removed. This guide does not instruct players to search for it.
Does route progress sync between devices?
No. Completed stages and Stuck Resolver checks are saved only in this browser using localStorage. There is no account, backend or cloud sync.
Evidence policy
What “confirmed” and “reported” mean
Confirmed facts are supported by an official Steam or first-party source. Reported route details require agreement from at least two independent domains.
Fields marked needs-check are hidden from deterministic guidance or explicitly labelled as unresolved. Desert and Rocks are common guide descriptions; Palm Trees and Casino Barn remain single-source aliases under verification.
