Sea Treasure Match 3
Shells and sea stars on a clock — each level sets a task and the time to finish it.

Sea Treasure sends the board underwater and fills it with shells, sea stars and the rest of the shoreline. Lines of three or more identical elements clear, and each level carries its own task to accomplish rather than a general score to beat.
Time is limited, and that single constraint changes what a good move is. A large match found slowly is worth less than two ordinary ones taken quickly, because the clock spends while you look. The players who finish these levels comfortably are the ones who clear steadily near the task target and stop hunting for something better.
The seabed art keeps pieces distinct, which matters here more than on an untimed board: at speed you are recognising shapes rather than reading them, and this one is drawn clearly enough to allow it.
Controls
Click or tap two adjacent pieces to swap them.
How to Play
- Read the task the level sets before your first move.
- Swap two neighbouring pieces to create a line of three or more identical elements.
- Work near the task target rather than wherever the board looks busiest.
- Keep the pace up — time is limited on every level.
Tips & Tricks
Learn the pieces by silhouette rather than colour. Shells and sea stars share a palette here, and under a clock the outline is what your eye can actually use.
