Minesweeper meets match-3, at the bottom of the sea.
You pilot a small submarine down to sunken wrecks. First you sweep the wreck grid to work out where the mines are. Then you extract the treasure you found in a match-3 board with a limited number of moves. The gold you bring back is spent at the Dock on upgrades for your next dive.
There is no final level. Depth increases without limit, and boards get wider, denser and more valuable the deeper you go. Every dive generates a new board.
Step one
Sweep the wreck
The wreck grid plays by Minesweeper rules. Revealed tiles count the mines around them, flags mark what you are sure of, and one wrong tap costs a heart. Sonar scans a patch of the board and pings any chest inside it.
Clean Mode generates boards that can always be solved by logic alone, with no forced guessing. If you prefer the classic random rules, you can turn it off in the settings.
Step two
Extract it, then spend it
Everything you uncovered goes into a match-3 board with a fixed number of moves. Match the gems to bank the loot. Run out of moves and you leave the rest behind.
Back at the Dock, gold buys hull plating, wider sonar, extra moves and a better salvage rig. New hull colors unlock as you reach greater depths, including holographic finishes.
