About S0

S0 is an action game about number bases, with challenges that range from building an intuitive understanding of different bases to testing your mental arithmetic. You explore number systems from binary to base 16 in a hand-painted world.

Career and sandbox

In career mode, you track and improve your mastery, unlocking increasingly difficult settings as you progress. Sandbox mode lets you explore and choose a challenge that suits you.

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.
