Short answer: never compare a participant number without its unit. Normalize the billing period, delivery mode, capacity unit, and secondary gates first; then verify the exact account category and region on the vendor's current page.
Key findings, verified 9 September 2026
- There is no universal participant limit. A ceiling may apply per month, room, activity, session, experience, host account, assignment, or embed.
- Mentimeter Free documents 50 participants per month plus one unlimited-participant session each month. Paid individual plans remove the monthly participant restriction and are billed yearly per presenter.
- Socrative Free documents 50 students per activity, five quizzes, one room, and 30 days of report history. Pro documents 300 students per activity.
- Wayground Starter documents up to 100 participants per session; Individual and School & District plans document up to 1,000, with regional differences.
- Crowdpurr Basic documents 20 participants and 15 questions per experience across three simultaneous experiences.
- Kahoot! capacity varies by account category, plan, and mode. TriviaMaker publishes separate capacities for teams, buzzers, crowd play, assignments, and embeds.
What is a quiz-app participant limit?
A quiz-app participant limit is the maximum number of people or submissions a plan permits within a defined unit. That unit may be a live session, room, month, event, assignment, experience, workspace, or host license. A number without its unit is incomplete evidence.
A useful comparison needs at least six fields: plan name, price and billing period, limit unit, live capacity, asynchronous capacity, and secondary gates such as questions, rooms, storage, hosts, reports, or premium modes. This evidence asset complements the participant-access matrix, which focuses on how people join rather than how many can join.
Normalized pricing and capacity matrix
| App and entry plan | Price evidence | Primary limit unit | Documented capacity | Other gates | Do not infer |
|---|---|---|---|---|---|
| Mentimeter Free | Free; paid Basic and Pro billed yearly per presenter | Participants per month | 50 per month, plus one unlimited-participant session per month | Imports and result exports require paid plans | One unlimited session does not mean unlimited recurring sessions |
| Socrative Free | $0 | Students per activity or room | 50 | Five quizzes, one room, 30-day report history | The 50-person ceiling is not a monthly pool |
| Wayground Starter | Basic entry plan; pricing and features vary by region | Participants per session | Up to 100 | Limited library access, storage, question types, and report features | A 100-person session does not imply unlimited stored resources |
| Crowdpurr Basic | Free | Participants per experience | 20 | 15 questions per experience and three simultaneous experiences | Three experiences are not 60 people in one experience |
| Kahoot! Basic or free | Free entry varies by account category | Players per live session or assignment | Typically 10–40 for many free personal, student, or K-12 accounts; free business-created games may be limited to 3 | Team mode and premium question features vary by plan | A limit from one account type cannot be applied to another |
| TriviaMaker Basic | Free | Separate capacities by play mode | 20 buzzers or 20 crowd participants; two Basic or Presenter teams | Assignments and embeds begin on paid tiers | A live crowd limit is not an assignment-entry limit |
Why Mentimeter's monthly unit changes the buying decision
Mentimeter's current Free plan documents 50 participants per month and one unlimited-participant session per month. Its FAQ defines the monthly figure as the total people engaged across presentations during the month, resetting on the signup-day anniversary. An ongoing presentation is not interrupted when the limit is reached, but after an eight-hour grace period another presentation cannot be made live until the allowance resets or the plan changes.
That unit can suit a team testing one large session but constrain frequent small workshops. Basic and Pro document unlimited participants and annual billing per presenter, so a buyer estimates paid licenses from the number of presenters rather than attendees.

Why Socrative's room and report gates matter
Socrative Free currently documents five saved quizzes, one room, 50 students per activity, and 30 days of report history. Essentials keeps a 50-student ceiling while increasing quizzes, rooms, and report history. Pro documents 300 students per activity, 30 rooms, and unlimited report history.
A teacher with 40 students may still need a paid tier because the quiz-storage or report-history gate is too narrow. Conversely, a teacher running temporary formative checks for one class can fit the free capacity even when another platform advertises a larger headline number.

Why Wayground's storage gate belongs beside capacity
Wayground's plan overview, updated 28 August 2026, documents up to 100 participants per session on Starter and up to 1,000 on Individual and School & District plans. The same table labels activity storage, library access, question types, Instructional Suite access, and reports as limited on Starter.
The official page says features and pricing can differ by region. The defensible capacity statement therefore pairs the broad plan overview with a regional checkout check at procurement time. Participant count alone can hide the resource-storage constraint that affects repeated classroom use.

Why Crowdpurr has three simultaneous limits
Crowdpurr Basic documents 20 people per experience, 15 questions per experience, and three simultaneous experiences. Its help center explains that experiences can be linked into a three-round game totaling 45 questions for the same 20-person audience. Capacities cannot be added across units: three experiences do not turn one room into a 60-player experience.
For event procurement, record audience size and desired rounds separately. Also verify whether live streaming, cumulative rankings, team mode, and automatic playback are available at the chosen tier rather than assuming every product-page feature shares one limit.

Why Kahoot! limits need an account-type label
Kahoot! says free accounts generally have low participant caps, typically 10 to 40 depending on whether the account is Personal, Student, or K-12. Its current personal table lists Basic at 10 for present and assign. The FAQ separately says a free Business user's self-created game may be limited to three players, while certain ready-to-play Kahoot! at Work resources provide a separate test path.
“Kahoot free limit” is therefore an ambiguous query. A reusable answer must name the account type, plan, mode, and whether the host created the game. The safest operational check is the player ceiling displayed inside the exact account before invitations are sent.

Why TriviaMaker separates live and asynchronous entries
TriviaMaker's current table lists Basic as free, Premium at $6.99 per month or $19 per year, Premium Plus at $39.99 per year, and Enterprise with custom pricing. More importantly, it publishes different rows for presenter teams, buzzers, crowd participants, assignment entries, and embedded entries.
Basic lists two teams and 20 buzzers or crowd participants but no assignment or embedded entries. Premium lists 50 live participants and 100 assignment or embedded entries; Premium Plus lists 200 live and 500 asynchronous entries; Enterprise lists up to 2,000. These are vendor-published capacities, not benchmarked throughput.

A reproducible seven-field verification method
- Name the use mode. Record live host-led, self-paced assignment, recurring monthly sessions, embedded quiz, or event.
- Record the billing unit. Note presenter, host, seat, workspace, month, event, or organization.
- Record the capacity unit verbatim. Use “participants per month,” “students per room,” or the vendor's exact equivalent.
- Separate live and asynchronous limits. Do not reuse an assignment-entry ceiling for a live game.
- Capture secondary gates. Check saved quizzes, rooms, questions, experiences, storage, exports, reports, team mode, and branding.
- Verify account category and region. Education, personal, business, and event plans may differ under the same product name.
- Save the official URL and date. Recheck immediately before a large purchase or event because pricing and caps are volatile.
Reusable procurement note: “Plan X, billed per Y, permits Z participants per [unit] in [mode], with [secondary gates], verified from [official URL] on [date].”
Worked examples
Teacher with four classes of 28 students. Socrative Free fits the simultaneous ceiling, but five saved quizzes and 30-day report history may be too restrictive. Wayground Starter also fits the session ceiling, while limited storage may change the decision.
Monthly all-hands for 180 people. Mentimeter's one unlimited Free session may technically fit one month, but a recurring program must verify presenter billing and the monthly restriction. Crowdpurr Basic does not fit. TriviaMaker requires a tier whose crowd limit covers 180.
Family event with 16 phones. Crowdpurr Basic and TriviaMaker Basic both fit the headline live capacity. Ready-made content, game format, presentation view, and host effort become more useful decision fields than price.
Method and limitations
We normalized six vendors under the same fields and rechecked their official pricing or support documentation on 9 September 2026. We did not purchase plans or run capacity tests. This asset makes units comparable and exposes uncertainty; it does not declare a universal price winner. The process follows our ranking methodology and public evidence ledger.
This matrix does not cover negotiated enterprise terms, taxes, currency conversion, discounts, education eligibility, regional checkout prices, legacy subscriptions, reliability benchmarks, or performance under load. A blank cell does not prove a feature is unavailable; it means the cited public table did not establish it for that plan.
Practical next step
Write the expected audience, number of hosts, sessions per month, and delivery mode on one line. Apply the seven-field method to the two finalists using their live pricing pages. If a capacity remains ambiguous, ask the vendor to confirm the exact unit before the event or purchase.
Correction path: report a changed price, plan, or limit through the corrections process with the exact table row and official source. Verification date: 9 September 2026.
