How to Fish Islands Guide
How to Fish is built around a linear chain of islands: five main stops, each unlocked by defeating that island's boss fish and each noticeably more dangerous — and more rewarding — than the last.
How Island Progression Works
You don't choose where to go next in How to Fish — progression is gated. Each island has its own quest line and a boss fish waiting at the end of it. Complete the quests, beat the boss, and the route to the next island opens up. This is the main reason "how do I unlock the next island" is one of the most common questions new players have: if you're stuck, the answer is almost always "go finish this island's boss fight," not "explore somewhere else."
| Stop | What Unlocks It | What's New |
|---|---|---|
| 1 — Starting Island | Where your boat crashes at the start of the game | Basic fish, your first shop board, first quests, entry-level weapons like the Knife and Brass Knuckles |
| 2 — Second Island | Defeat Island 1's boss | First ranged weapons (Pistol), tougher common fish |
| 3 — Third Island | Defeat Island 2's boss | Shotgun and mid-tier gear, more dangerous creatures |
| 4 — Fourth Island | Defeat Island 3's boss | SMG/Sniper-tier gear, harder boss encounters |
| 5 — Military / Final Area | Defeat Island 4's boss | Endgame gear including the Assault Rifle, the game's toughest fights, and the path back home |
Tips for Moving Between Islands
- Don't rush the boss before you're geared up. Islands scale in difficulty, and going in with last-island's weapon is the most common reason a boss fight drags on or wipes the group.
- Clear quests before you leave, not after. It's easy to miss an island's side content once you've moved on to tougher water elsewhere.
- Bring a ranged weapon to every boss fight. Melee alone gets significantly harder to rely on from the second island onward. See the weapons guide for what's available at each stage.
- Islands are fully physics-driven playgrounds. You can climb trees, rocks, and structures, which occasionally opens up shortcuts or better fishing spots than the obvious path.
- Play with friends to move faster. Island and quest progress is shared in co-op, so a full 1-4 player group can farm money and clear bosses noticeably faster than solo. See the multiplayer guide.
What's at the Final Island?
The fifth and final stop introduces a military/volcano-style area with the game's toughest boss encounters and its best gear, including the endgame Assault Rifle. It's also where the story wraps up — your route home after the opening boat crash. Because official proper names for islands 2 through 5 haven't been consistently published yet, this wiki refers to them by position; we'll update this page with confirmed names as soon as they're documented.
Exploration & Physics Traversal
Because How to Fish runs on a physics engine rather than pre-scripted movement, islands are more explorable than a typical fishing game's map. Trees can be climbed (as shown in the palm tree screenshot above), rocks and structures can be scaled or knocked around, and thrown items like dynamite interact with the environment realistically rather than following a fixed animation. Practically, this means it's often worth poking at the edges of an island — a climbable tree or an out-of-the-way ledge can hide a better fishing spot, a shortcut, or just a good view before your next boss fight.
Common Mistakes When Progressing
- Fighting a boss with last-island's gear. Each island's boss is tuned around that island's available weapons — if you're struggling, the fix is almost always "grind money on the current island" rather than "get better at dodging."
- Leaving quests unfinished. Side quests are easy to forget once you've moved past an island, and some rewards are easiest to grab before you advance.
- Exploring solo when co-op is available. A group covers water and clears bosses faster since island progress is shared — see the multiplayer guide for how to set that up.
Solo vs. Co-op Island Progression
Whether you're pushing through How to Fish's islands solo or with a full four-player group, the unlock rule stays the same: finish the current island's boss to open the next one. The difference is speed — a group can fish more spots simultaneously, pool damage output against a boss faster, and generally reach each new island sooner than a solo player grinding the same content alone. Neither approach locks you out of anything permanently; a solo save can always add friends later, and vice versa.
Quick answer: How to Fish has 5 islands total. You unlock each one in order by finishing the current island's quests and defeating its boss fish — there's no way to skip ahead.
