Marimo: My Moss Pet

A tiny green moss ball is waiting on your windowsill.

Marimo: My Moss Pet is a calm pet game about raising a marimo, the round moss ball that grows in cold lakes. There is no rush and nothing to lose. Give it clean water, a little nutrient and some sunlight, and watch it grow millimeter by millimeter, the way a real marimo does.

WHAT YOU DO • Care: change the water, add nutrient, open the curtains for sunlight. Your marimo shows how it feels. • Pet it: tap and drag your marimo around the tank. It answers with little words. • Pop bubbles: photosynthesis makes bubbles rise. Pop them for gems. • 4 mini-games: Bubble Pop, Marimo Roll, Tank Cleaning and Marimo Merge. Short rounds, gems as rewards. • Decorate: pebbles, water plants, a castle, a snail, shrimp and medaka fish. Ribbons and hats for your marimo. • Collect: six marimo kinds. Sakura, sky, snow, night and golden marimo appear from splitting or from daily gift cards. • Raise friends together: a bigger tank holds more than one marimo.

A GAME THAT WAITS FOR YOU Your marimo keeps growing slowly while you are away, and it never dies. Come back after a busy day and it is still there, a little bigger. Daily missions and a small daily gift give you a reason to visit, never a punishment for staying away.

• Plays offline. No account, no ads, no in-app purchases. • Ten languages: English, Korean, Spanish, Portuguese, French, German, Turkish, Polish, Indonesian, Italian. • Made by a small team that keeps a real marimo on the desk.

Facts in the game are based on the real plant: marimo grow about 5 mm a year, prefer cool water and soft light, and split when they get large.
