How many players can join a free Kahoot?

There are two answers, which is why searching for this is so annoying.

On Kahoot's free plan, now called Kahoot! Go, a K-12 school teacher account can host 40 participants. A personal account, a higher-education teacher account, or a student account can host 10. Same free plan, same name, four times the capacity depending on a category most people never consciously picked.

Those figures are from Kahoot's own participant-limits support article, which was last updated on 3 August 2026. If you are reading this much later, check it again rather than trusting this page: limits move.

Why there are two numbers

The cap is attached to your account type, not to your plan. Kahoot asks what kind of user you are when you sign up, and that answer sets which limit table you fall under for as long as the account exists.

The trap is that the choice felt trivial at the time. A secondary teacher who signed up at home one evening and picked personal use, or a university tutor who answered honestly, both end up on 10. Neither did anything wrong, and nothing in the product tells them they are on a lower cap than the teacher down the corridor with an identical free plan.

The schools pricing page shows 40, which is correct for the audience that page is written for. If you land there from a search and your own account is not categorised as K-12 teaching, that number is not the one that applies to you.

Assigning does not get you more room

A common assumption is that the cap applies to live games and that setting a kahoot as homework gets around it. It does not. On every free tier the present limit and the assign limit are the same: 40 and 40, or 10 and 10.

The two numbers only diverge much further up the range, on the school and district plans, where assigned work is allowed a far larger cohort than a single live room. On the free plan there is no gap to exploit.

How to tell which one you are on

The reliable way is to look rather than assume. Open your account settings and find how the account is described, or simply start a game and watch the lobby: the cap announces itself when the thirty-first or eleventh player is turned away.

Do that before the lesson, not during it. Which brings up the part that actually matters.

What happens when you hit it

Players beyond the cap cannot join. There is no queue and no overflow, and the room does not degrade gracefully: a student who taps in late is simply told the game is full, in front of everyone.

If you teach classes of thirty and you are on the 10-player limit, this is not an edge case you will discover eventually. It is the first lesson you try it in.

What to do about it

Check the category first. If your account is genuinely a K-12 teaching one and is showing 10, that is worth raising with Kahoot support before spending anything. The gap between 10 and 40 is free.

Split the class. Two rounds of fifteen is worse than one round of thirty, but it works and it costs nothing. Reasonable for an occasional activity, miserable as a weekly routine.

Pay for the headroom. The paid teacher plans step up from 50 upwards. Prices and promotional discounts change often enough that quoting them here would be out of date within weeks, so read them from Kahoot's own schools plans page rather than from any article, including this one.

Or use something with a higher free cap. We make Tikroo, so treat this paragraph with the scepticism it deserves: our free plan carries 100 players in a session and 100 participants a month, which covers three classes of thirty. It is also limited in ways Kahoot's is not, and the honest comparison is on our plans page rather than in a sentence written by us.

Where Kahoot is the better answer

If your school already has a Kahoot subscription, none of this applies to you and switching for a player limit would be a poor reason to abandon a library of kahoots your colleagues share.

If what you want is specifically the thing Kahoot has spent a decade refining, which is the large-scale quiz with the music and the podium, it is very good at that and the free cap is the only thing standing in the way. Paying for one teacher plan is a smaller change than moving platforms.

The reason to look elsewhere is not that Kahoot is worse. It is that a 10-player cap and a class of thirty are simply incompatible, and no amount of goodwill fixes an arithmetic problem.

The short version

Check whether your account says 40 or 10 before you plan a lesson around it, because the free plan is not one number and the one you get was decided by a dropdown you probably do not remember.
