Chichi Reef Warrior: the free conservation game about reef cleaning

The game was made by One3One4 in collaboration with Flip Design Pvt Ltd under a conservation theme. The player drags Chichi across the screen to clean toxins from the water while avoiding predators. Other tasks include circling oil spills to contain them, freeing fish trapped in plastic bags, trapping predators and diving for treasures. A level is complete when Chichi has guided its way over the reef bed, cleaning and collecting jeweled hearts.

The game started on iOS, and an Android version was planned for release on World Oceans Day, June 8, 2015, whose theme that year was Healthy oceans, Healthy planet. A browser version was offered as a Unity3d game on a Facebook canvas. The developers also invited brands and nonprofits to place conservation messages inside the game.

The learning content is environmental. Players meet the idea that reefs shelter animals from small herbivorous fish to large predators and protect shores as a barrier. They see why plastic waste harms marine life, because turtles and birds mistake plastic for food, and the game explains coral bleaching, in which warm water makes corals expel the algae that give them color. Ocean acidification is the third theme, linked to the carbon dioxide the sea absorbs from the atmosphere and to how that affects the shell-building minerals available to animals.

The game text also covers corals themselves. Corals draw energy from symbiotic algae in their tissue and also feed on zooplankton, sediment and other tiny organisms, and the game states that researchers found corals eat plastic at a rate only slightly below their normal feeding. It adds that the ocean absorbs about a quarter of the carbon dioxide people release, so rising atmospheric levels raise the level in the sea, where the gas combines with water to form carbonic acid.

The web address of One3One4 no longer leads to a website. The Flip Design address loads a placeholder page with links to two older versions of its own site and no mention of the game. The App Store listing for the iOS version no longer loads, and the Facebook address forwards to a Facebook login page, so no working copy is confirmed as of November 2026. A web search for the title and both developers returned no page about the game.
