Blooket's free plan covers a full class, so most teachers never need to pay. The paid plan, Blooket Plus, adds extras: more question sets, the ability to create folders, enhanced game reports with more detail, and early access to new game modes. The free plan already includes every game mode, homework assignments and basic reports — the paid plan is mostly about organisation and deeper data. If you run Blooket every day across many classes, the extras save time; for occasional use, free is enough.
