About Code 9

Code 9 is a Kakuro-inspired puzzle game where you combine numbers in rows and columns to meet each puzzle’s conditions. You can use each of the digits 1–9 only once per puzzle.

Puzzles and themes

The game has 100 math puzzles, with gameplay variations introduced across different puzzle sets. Unsolved puzzles save your progress so you can return to them later. Choose from six vibrant themes or a blank minimalist theme.

Music

The musical score changes as you play, or you can switch to ambient-only audio.

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.
