Play Treasure Cove! Online

Game Overview

Treasure Cove! is one of those weirdly charming edutainment games from the MS-DOS era where you play as the Super Seeker, basically an underwater janitor trying to clean up an oil spill. The Master of Mischief (classic villain name) has been dumping experimental gunk into the ocean, and now you're stuck chasing down pufferfish to plug leaky pipes while dodging these annoying "goobie" blobs that drain your light meter.

At first it feels simple—swim around, grab starfish that give you word clues like "three" or "eels," then shine your flashlight on the right group of sea creatures to uncover gems or the pufferfish you need. But the starfish riddles get trickier fast, and the higher your rank, the more aggressive the light-stealing fish become. I remember getting stuck for ages on one level because I kept misreading the clues and shining my light on the wrong coral formations.

The real hook is rebuilding the Rainbow Bridge gem by gem—every few rounds, you surface to see your progress, and there's something satisfying about watching it slowly extend toward the polluted island. Just don't expect it to stay easy; by the time you hit three stars, you'll be sweating over cryptic clues while fish zip at you like torpedoes. It's oddly tense for a game about marine cleanup.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
