“The company already has “basic” and “pro” versions. Basic is free; the pro edition is $3 per month per teacher; and the premium version is $6 per month per teacher.
Kahoot!’s free, basic version gives teachers access to games for class-sized groups and allows them to create games with multiple choice quiz questions. Students can complete self-paced games on their own. Educators also get access to games and quiz questions provided in a company-maintained library to which members of the Kahoot! community can contribute their own games and questions.”
