About
Dive into Underwater Kingdom, a match-3 adventure through six oceans.
Swap shells, fish, starfish, coral, bubbles and crystals to line up three or more. Match four to forge a Rip Current, cross two runs for a Pearl Burst, match five for a Rainbow Tide, then set them off to sweep the board. Every round of a cascade pays more than the last.
SIX OCEANS, OVER 2,000 LEVELS
Sunny Reef, Pirate's Cove, Jellyfish Bay, Lost Atlantis, Volcano Depths and The Abyss, each with its own painting, its own obstacles and its own boss. Twelve chapters deep.
BOSSES THAT FIGHT BACK
The Crab King, the Ghost Captain, the Jelly Queen, the Stone Guardian, the Lava Eel and the Deep Angler ink the board with seaweed every few moves. Forge power pieces and run deep cascades to land hits before the moves run out.
TREASURE DIVES
Short, crowded side quests: six colours, sixteen moves, a board full of obstacles, and gold and gems no reef level pays.
BOOSTERS WHEN YOU NEED THEM
Pufferfish Bomb, Dolphin Dash, Whirlpool, Mermaid Song and Electric Eel wait in the tray under the board.
EARN STARS, CLIMB THE RANKS
Every star counts toward your Ocean Rank, from Tidepool Scout to Ocean Sovereign. Open a daily chest, fill a treasure vault as you play, and bring a cheerful Ocean Explorer along for the ride.
Free to play. Optional purchases for gems, a starter pack, the treasure vault and an Explorer's Pass that makes every dive free. Any purchase removes ad breaks for good.
