Explore a peaceful underwater puzzle map, one short dive at a time. Find matching treasures and trace a clear path between them through a changing reef.

PLAN EACH ROUTE
Drag from one revealed treasure to its matching pair. Paths follow neighboring grid cells, bend up to three times, and must avoid other treasures and reef rock. Every successful pair uses one move, so open cells become valuable routes of their own.

DISCOVER THE REEF
Begin with a compact board, then explore larger layouts with color gates, shifting lift zones, buried treasures, and layered reef rock. Matching treasures can pass through their own color gate. Nearby matches thin the sand, while lift zones exchange their contents after every two pairs.

THREE DISTINCT TOOLS
Use a rearrange to redistribute remaining treasures, a cross clear to remove a layer of sand or reef rock across one row and column, or a position swap to exchange two revealed treasures. Each tool is available once per dive and never clears a target pair for you.

A COMPLETE SHORT CHALLENGE
Clear the target pairs within 24 moves and 90 seconds. Earn up to three stars based on your remaining moves, replay dives to improve your score, and follow the reef map as fresh routes open. A daily tide presents a local board and stores your personal record on your device.
