Octo Market: Underwater Supermarket
About Octo Market: Underwater Supermarket
Octo Market: Underwater Supermarket puts you in charge of Otto, a cheerful octopus with a dream: running the best supermarket on the ocean floor. With eight arms to carry goods, Otto harvests algae, corals, pearl candy, and cosmic treats, stocks the stalls, and collects coins from a steady stream of customers — clownfish, turtles, jellyfish, sharks, and even legendary visitors from the deep. The game wraps all of this in bright cartoon graphics and easy one-finger controls.
Seven unique departments give the store its shape: Pearl Farm, Volcano Grill, Cryo Grotto, Kelp Forest, Sunken City, and Cosmo Bar, each with its own mechanics and its own music. Merge stalls for higher-tier goods and bigger profits, hire crab helpers, couriers, and cashiers so the store keeps running even without you, and work toward the ultimate goal — building a rocket and sending the whole operation to the stars.
How to Play Octo Market: Underwater Supermarket
Otto operates almost automatically once you position him correctly. Swim to a bed or station and he picks up goods on his own; stand next to a stall and the goods go onto the shelf by themselves; stand at the cash desk and coins are collected from customers who have already taken their items. Building works the same way — stand on a glowing tile and coins are spent automatically, with larger structures taking a few seconds to complete, though you are able to speed them up.
