The game is viewed from a side-on perspective as the diver moves through underwater areas. The main objective is to explore each section, locate pirate treasure, and survive environmental hazards and hostile sea life while managing movement through the water.

Progression is based on reaching or completing successive areas rather than on a character-building system. The available documentation does not reliably establish the complete stage count, scoring rules, or every item and hazard, so those details should not be assumed.

Explore methodically instead of rushing through unfamiliar areas. Check the surrounding space before committing to narrow passages or approaching hazards, and keep a safe route back through the level in mind.

Because reliable documentation of the game's complete mechanics is limited, use the on-screen presentation and level behavior as the primary guide rather than relying on undocumented passwords or control charts.
