About this game
Kokushi: lost island is a pure-exploration adventure with no combat and no quest log. You wander a living island alone, where time never stops, searching for fourteen mah-jong tiles to complete the legendary Kokushi Musou hand.
➤ Each play session takes around 10 to 20 minutes.
■ Guide UI — Always Know What to Collect
The on-screen Musou Gauge highlights every missing tile, so you can focus on exploration. Even players who know nothing about mah-jong can enjoy the hunt.
■ Beware the Sunset
Exploration isn’t unlimited. Time advances in real-time, and the island is swallowed by darkness when the sun goes down. Gather all fourteen tiles before night falls.
