About Connect-X

Connect-X is a 3D puzzle game with 50 mathematical brainteasers that increase in complexity and difficulty. In each level, you fill bubbles with whole numbers, following relationships shown by arrows in different colors.

Complete every relationship correctly to finish a level and earn stars. Use the stars to unlock more puzzles that challenge your understanding of numbers, including basic concepts such as divisibility and addition.

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.
