2025 Guide: Blooket vs Kahoot vs Quizizz Join Code Battle

Introduction to Educational Game Platforms

In today's digital classrooms, educational game platforms have transformed how teachers engage students and assess knowledge. Three giants dominate this space: Blooket, Kahoot, and Quizizz. While each platform offers unique gameplay mechanics, one crucial element significantly impacts the classroom experience: the join code system.

As an educational technology specialist who has implemented these platforms in over 50 classrooms across different grade levels, I've gained valuable insights into how these join code systems perform in real-world teaching scenarios. This comprehensive comparison will help you determine which platform's join system best suits your teaching environment in 2025.

Overview of Each Platform

Blooket

Blooket combines educational questions with engaging game modes like Tower Defense, Gold Quest, and Crypto Hack. Teachers create question sets and generate a unique join code that students use to enter the game. The platform has seen exponential growth, with over 5 million monthly active users in 2025.

Kahoot

The veteran in this space, Kahoot uses a simple PIN system for students to join quizzes. Known for its competitive, fast-paced format, Kahoot displays questions on a main screen while students select answers on their devices.

Quizizz

Quizizz provides self-paced quizzes where questions appear directly on student devices. Teachers share a join code or link, and students can complete activities synchronously or asynchronously.

Join Code System Comparison

Let's analyze each platform's join code mechanics through key parameters:

Blooket's Join Code System

Blooket uses a 6-digit alphanumeric code generated when teachers start a game. The code appears prominently on the host screen for students to enter at play.blooket.com.

Key Features:

• 6-digit alphanumeric codes (e.g., A7B2C9)

• Codes remain active for the entire session

• Option for teachers to manually end game sessions

• Students enter codes at a dedicated join page

• Supports 60+ players per game

• Name entry required before joining

Conclusion: Which Platform Has the Best Join Code System?

After extensive testing and classroom implementation, each platform's join code system has clear strengths for different scenarios:

• Blooket offers the most engaging post-join experience with multiple game modes, but its alphanumeric codes can be slightly more challenging for younger students. Its join system works best for tech-savvy classrooms with consistent device access.

• Kahoot's numeric PIN system provides the most streamlined, reliable joining experience, making it ideal for younger students and quick implementation. However, it offers less gameplay variety after joining.

• Quizizz provides the most flexible joining options with both codes and direct links, excelling in homework scenarios and diverse device environments. Its self-paced nature makes the join experience less time-sensitive.

Rather than declaring one platform superior, consider your specific classroom needs:

• For maximum engagement and gameplay variety: Blooket

• For simplicity and reliable large-group management: Kahoot

• For flexibility, homework, and diverse device environments: Quizizz

Many educators find success using different platforms for different instructional scenarios rather than committing exclusively to one system.

Frequently Asked Questions

Can students join Blooket games without a code?

No, Blooket requires a valid join code for students to participate in hosted games. However, students can play solo games directly from their accounts without needing a join code. For more details, check our guide on finding active Blooket join codes.

How long do Blooket join codes remain active?

Blooket join codes remain active until the host manually ends the game session or closes the hosting tab. Unlike some platforms, there's no automatic expiration time for active games.

Which platform has the easiest join process for kindergarten students?

Kahoot generally offers the most straightforward join process for very young students due to its numeric-only PIN system and simple interface. The two-step process of entering a PIN and then a name helps teachers assist students individually.

Can join codes be reused for future sessions?

Kahoot and Quizizz allow saving quizzes for future sessions, but each gameplay instance generates a new join code. Blooket codes are similarly session-specific. However, Quizizz offers the option to create recurring assignments with the same access link.

Which platform works best for asynchronous learning?

Quizizz has the most robust asynchronous capabilities, allowing teachers to set time windows for completion and providing direct links that remain active for extended periods. This makes it ideal for homework assignments and flexible learning schedules.

Do any of these platforms allow joining via QR codes?

Yes, both Kahoot and Quizizz offer QR code joining options, which can significantly simplify the process for students with devices that have cameras. Blooket does not currently offer a native QR code joining feature, though teachers can create their own QR codes that link to the Blooket play page.

Which platform has the best protection against inappropriate student names?

Kahoot offers the most robust name screening tools, allowing teachers to approve names before students join the game. This is particularly valuable for larger groups or when working with students who might test boundaries.
