About Hiis

Hiis is an open-world sandbox experimentation game in which you play as a sage on an isolated island. You explore its secrets, discover mystical plants and brew potions, while helping the island’s people with your creations.

Explore and experiment

Find over 30 plants, each with its own properties and reactions. Farm plants you discover in the wilderness, then use their products as the main ingredients for brewing. Experiment with over 40 potions to work out their effects; they can help other people or aid your exploration. Record your discoveries in your handbook.

Make a home

Customize your home and garden as you develop your farm and work with the plants you find on the island.

Help the islanders

Listen to dozens of people describe their problems, then experiment with potions to find one that helps. Completing these quests puts your brews to use in solving their problems.
