About Nullum

Nullum is a minimalist puzzle game where you clear the playfield by combining tiles with matching numbers. You move a tile onto an adjacent tile: if the numbers match, both tiles disappear; otherwise, they are added together. Plan your moves to eliminate all the tiles and unlock the next challenge.

The game has 40 handcrafted levels and original music composed specially for it.

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.
