There is a limit of 500 players who can join a single Quizizz game. Just make sure you have a high-speed internet connection if everyone is playing from the same venue.
Quizizz can also support games with thousands of players, but this facility is not available on our regular accounts. If you are presenting Quizizz to more than 500 participants, or plan to conduct an event using Quizizz, please reach out to us at firstname.lastname@example.org with some details about your requirements. We would love to help make your event a success!
