How to Play Ocean Treasure: Controls and Beginner Tips
This guide helps you begin Ocean Treasure with a clear plan. Open the original game page using the link below, read the current start-screen instructions, and make your first attempt about learning how the game responds. The control notes below follow the game's published instructions.

Your first objective
Pilot a cheerful yellow submarine, collect golden pearls, dodge sea hazards, and unlock treasure chests in 1,000 progressively challenging HTML5 levels. Your goal is simple: find every golden pearl in the level, then steer toward the locked treasure chest.
Controls and starting the game
Play instantly for free on mobile or desktop—no download required.
How to Play On a computer, use the arrow keys or W, A, S, and D to move the submarine in all four directions.
On a phone or tablet, hold the large on-screen arrow buttons or drag directly across the ocean playfield to steer.
Press P to pause, R to restart, or M to toggle the optional sound effects.
Clear the pearls before approaching the chest
Search the level in a simple pattern and watch which pearls remain. The treasure chest becomes available after the final pearl, so reaching it early does not complete the stage. Make small steering adjustments near hazards and leave room to turn away. Learn the submarine's movement in the gentle opening level before the later challenges.
A useful first-session routine
Start with one manageable section and test each action separately. Once movement feels comfortable, combine it with the main objective rather than adding every action at once. After a failed attempt, change one decision and try again; this makes it easier to understand which timing or route helped. On a phone, use the visible touch controls. On a computer, click inside the game before using its keyboard commands. Fullscreen may require a direct tap and depends on your browser.
