What is Scotix?

Scotix is a free competitive cognitive-training platform. Instead of dull drills, every challenge is a quick, competitive match — play a solo Practice round to warm up, or enter a ranked 1v1 duel against an AI opponent matched to your skill. Your ELO rating rises and falls with every result, so there is always a reason to play one more round.

The arena spans three disciplines: arithmetic speed, grid logic, and working memory. Pick any game below to read its full how-to-play guide, rules and strategy tips, or jump straight in and play free.
