Questions people ask

Yes. Every lesson, exercise, playground, game and the Arena can be used without paying and without a credit card, and it will stay that way. Certificate exams and Hex's hints and error explanations are free too, plus 15 questions a day to the AI tutor once your email is verified; since they cost AI money, that may change. Supporters get a badge, cosmetics and bonus coins; PRO adds AI credits for Ask Hex. No lesson is locked.

Every page was rearranged into four hubs: Learn, Play, Arena and Community, plus You behind your avatar. Since 2.0 there is more: the Arena, 12 languages, certificates with exams, the village and Jobs. Your progress, streak, coins and cosmetics are safe.
