Dive into ocean jigsaw puzzles: clownfish tucked into an anemone, a green sea turtle at the surface, a humpback whale breaching off Hawaii, and a busy coral reef. Free to play in your browser.
Open water is the hardest part of any sea puzzle, because large areas of blue look the same. Build the animal first, then work outward and use ripples, bubbles, and slight changes in shade to place the water pieces.
Reef scenes are the opposite: full of texture and colour. Group pieces by coral type and fish colour, and the reef comes together in sections.
Clownfish in an Anemone. The bright orange and white stripes stand out clearly against the green tentacles.
