Three islands, three tiers

Starter Island (free), Shipwreck Cove (1.0M-1.1M Gold), and Sphinx Sands (~25M Gold, 4x Luck). Each island brings denser spawn tables and higher-tier gear.

How to travel

Talk to the pirate NPC at the far end of the Starter Island dig area. Pay the unlock fee once per island — you can hop back and forth freely.

Shipwreck Cove cost (verified range)

The travel cost for Shipwreck Cove sits in a verified range: 3 sources say 1.0M, 3 sources say 1.1M. The Travel ROI tool lets you choose between both.

Sphinx Sands 4x Luck

Sphinx Sands grants 4x Luck to all players present. The community-reported travel cost is 25M (single YouTube source). Treat as soft until verified in-game.

Why travel matters

Better islands generate more Gold per hour. Use the Travel ROI tool to decide if the unlock cost breaks even in your remaining play time.
