Kahoot! vs Quizizz vs Blooket: Which Quiz Tool Is Best?

Three tools dominate the classroom quiz space: Kahoot!, Quizizz and Blooket. All three are free, game-based and work in any browser. But they feel very different in practice. Here is a detailed comparison to help you choose the right one for your class.

Kahoot!

Format: Teacher-paced, live game show. All students answer the same question at the same time. A countdown timer adds urgency; points are awarded for correct answers and speed.

Best for: Whole-class review, lesson starters and energetic competitive activities. The leaderboard and music create genuine excitement.

Limitations: Fast readers and confident students dominate the leaderboard. Students who guess randomly can outscore students who understand the material but answer slowly. Not ideal for formative assessment where you need honest data.

Free plan: Unlimited quizzes, up to 10 players per game on the free plan (as of 2024 — this limit changes). Accessing large question banks requires a paid plan.

Quizizz

Format: Self-paced by default — students work through questions independently, at their own speed. Can also be run live as a class game. Memes appear after each answer, making it feel more like a game than a test.

Best for: Homework review, independent practice and classes where you want students to work at different speeds. Better formative data than Kahoot! because speed does not affect accuracy scores.

Limitations: The self-paced format loses the shared energy of Kahoot!'s live format. Some students rush through without reading carefully.

Free plan: Genuinely unlimited — unlimited quizzes, unlimited students, no player cap. One of the most generous free plans in edtech.

Blooket

Format: Multiple game modes — Tower Defense, Gold Quest, Café and others — where answering questions correctly gives you resources to play the underlying game. Each game mode feels entirely different.

Best for: Engagement-first contexts where you want students to stay on task for a full period. Students love the game variety and often ask to play again.

Limitations: The game mechanics can distract from the content — students focus on the game more than the questions. Setting up is slightly more complex than Kahoot! or Quizizz. Free plan limits some game modes.

Free plan: Free accounts can access most game modes and create unlimited question sets. Some modes require a paid plan.

Side-by-side comparison

Which should you use?

• Use Kahoot! for high-energy whole-class starters and review sessions where participation and atmosphere matter most.
• Use Quizizz for homework, self-paced practice and when you want reliable formative assessment data.
• Use Blooket when engagement is the priority and you want students to stay on a task for an extended period.

Many teachers use all three — Kahoot! for energy, Quizizz for data, Blooket for longer focused sessions.
