Balance an aquarium, not just a board.
How to play
Each swap uses 3 oxygen. Diamonds restore oxygen; circles, triangles and crosses gather food for three different fish. Each swap yields up to 4 of each food or oxygen and 8 pearls, including cascades. Plant coral for 8 pearls to gain 6 oxygen and fish shelter. Select a circle, triangle or cross tile, then adopt its fish for 12 pearls, 9 matching food and 2 oxygen. Shelter all three species within 18 swaps before oxygen runs out. Coral and fish purchases do not use swaps.
Touch or click tiles. Keyboard: Tab to a tile, arrows to navigate, Enter or Space to select. New run starts a fresh board.
