About Sum

Sum is an open-world sandbox game set on a remote island with a randomly generated environment that changes in real time. As a castaway, you gather limited resources, make tools and adapt to the conditions to survive and escape safely.

Survive on the island

You can combine items to make supplies for survival, hunt animals with snares and weapons, and build a space of your own using different buildings. The weather changes in real time, shaping the natural environment you must live in.

Cooking

Collect ingredients to prepare 27 different dishes, each associated with a country. Making them earns special rewards.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
