In How to Fish by Dazed Games on Steam, the secret developer island is the red-blip island with a roofed casino. The sailing route once used to reach it no longer works in current builds.
How to Fish, the physics-based co-op fishing-and-shooting game from Dazed Games on Steam, hides an offshore island that appears as a red blip once you reach the late game. The island contains a roofed casino, but the old volcano-run trick for sailing across no longer gets you there. Progress through the five islands, finish the game, enter free roam, and skip the removed crossing while farming the volcano and its final boss.
The red-blip island is the only real lead
The “secret” or developer island refers to the island marked by a red blip offshore during the back half of the game. It appears while you’re working through the fifth island — the volcano — and routing the lava whale final boss.
Key The island contains a roofed casino. The game provides no location, quest, or navigation marker leading to it beyond the offshore red blip.

What players know about the island clue
| Clue | What it means |
|---|---|
| Red blip offshore | An island marker that shows up out at sea during late-game runs |
| Roofed casino | The building located on the island |
| Late-game context | Seen while farming the volcano island and routing the final boss |
| Patched shortcut | A separate trick for reaching the final island early was removed as unintended |
The red blip is a map marker rather than a signposted destination. It becomes relevant during endgame farming, when you’re already dragging the final boss around the volcano island. Look for a red marker at sea and the covered casino on its island.

Can you still sail out to it?
No. The old approach involved sailing toward the red-blip island with the mutated whale following close behind. In current builds, the boat will not complete the crossing even with the boss pressed against it. The game no longer provides a working route to the island.
This route is separate from the shortcut that allowed players to reach the final island early. Dazed Games patched that shortcut because it was unintended. The red-blip crossing was a separate community route that stopped working, not the specifically patched shortcut to the final island.
If you’re mid-run, don’t burn final-boss attempts trying to drag the mutated whale out to the red-blip island — fight it right on the volcano island, using the army tent as cover.
What to do about it right now
Progress through all five islands normally
Complete each island’s quests and bosses until you reach the volcano. The removed shortcut will not support a current run.
Finish the game to open free roam
Watch for the red blip offshore
While roaming, watch the map for the red island marker out at sea.
Skip the removed sailing route
Don’t build a current run around the old crossing. Use it only when deliberately testing an older version.
