What does Prime Time train?

Prime Time trains number theory fluency through short rounds with immediate feedback.

Can I embed Prime Time?

Yes. Open the Embed tab below the game to copy a mini-game iframe or a full-game iframe for another page.

Does Prime Time work with age filters?

Yes. Age-filtered library links pass the selected band into the game so the first round starts at an appropriate difficulty.

Why is Prime Time excluded from worksheets for now?

The worksheet registry documents this game as unsupported because the current paper renderer cannot yet preserve the interaction or diagrams that make the browser version fair.
