The Lost Crystal

Crystal-clear ocean depths, shimmering seashells, colorful starfish, and rare pearls fill the underwater landscape, where ancient, legendary treasures lie hidden. In “The Lost Crystal,” you’ll join a charming mermaid on a journey to explore the mysterious ocean floor and unravel ancient secrets. Ahead of you lie more than 55 unique levels with constantly changing objectives and tricky underwater puzzles. Successfully completing tasks helps you progress through the story map, unlock new challenging locations, and collect valuable crystals safely hidden among the coral reefs.

How to Play?

Swap adjacent seashells, bubbles, or fish to form straight lines of three, four, or five identical elements. Keep in mind the strict swap rule: you can only move underwater objects vertically or horizontally; any diagonal moves will immediately be blocked by the game board. Keep an eye on the precise lists of current objectives in the top-left corner of the screen, which specify particular types of fish and the number of items needed to complete the round. Try to form the longest possible chains of seashells to instantly create powerful boosters and clear large areas of the board in a single move. Activate special water boosters in challenging situations to easily break through tough obstacles and stay within the round’s time limit. Earn the maximum number of bonus points for beautiful combinations, collect all the target figures, solve all the mermaid’s puzzles, and find the main magic crystal at the bottom.
