To keep Kahoot! running smoothly for all, we have set a limit of 4,000 players per game PIN. However, games of this size require excellent bandwidth, WiFi, and/or cellular reception.
It's also important that you host such a game on a laptop or desktop with moderate hardware (like an i5 processor and 8GB RAM). Games are reliant on the hosting device to process responses from players. On a rare occasion, issues in gameplay can be attributed to the hosting device's hardware.
Also, please let us know if you are planning a kahoot of 1000+ participants and we can advise you on the best course of action. To reach us, please login to your account and use the "Support" button in the top nav bar.
I had at least 3,750 players joined but hadn't reached 4,000 players, yet no one could join my game. Why?
- We have a "soft limit" of 3,750. This means our servers periodically scan for games that exceed 3,750 and disable joining. We have this in place for now because our "hard limit" of 4,000 is fairly new and needs some more testing before we let it be the only limiter of players.
