About this game

Open88 is an expedition adventure built around Tide Coil, a unique serpentine dive through sunken harbor routes. Guide a glowing sea serpent across reefs and wrecks, collect emerald cores and gold coins, and raise a tide multiplier by chaining alternate finds. Explore Coastal Drift, Reef Maze, Wreck Dive, and Abyss Coil, unlock new charts with stronger scores, study the Harbor Log, fill the Treasure Vault, and track Expedition Marks as you manage a complete search for lost underwater wealth.
