Educational & Classroom Partnerships
Multiplayer Sudoku is widely used by elementary schools, high school STEM programs, university math clubs, and competitive logic puzzle leagues. We actively support educators and academic institutions worldwide by offering:
- Ad-Free Educational Whitelisting: Verified school domains and classroom networks can request full ad-free access to ensure distraction-free student learning.
- Private Tournament Creation: Tools to host closed-circuit 30+ player simultaneous tournaments for classroom competitions and STEM festivals.
- Pedagogical Academy Modules: Free printable worksheets and step-by-step interactive lesson plans designed around constraint satisfaction and deductive logic.
Responsible Vulnerability Disclosure & Bug Bounty
We take platform security and fair play seriously. If you discover a security vulnerability in our client frontend, WebSocket engine, or REST endpoints, please report it immediately through our support form with "Security Vulnerability" in the title.
Responsible Disclosure Guidelines:
- Provide detailed reproduction steps, proof-of-concept payloads, and affected URLs/endpoints.
- Do not exploit the vulnerability to view, modify, or corrupt user data or disrupt live server operations.
- Grant our engineering team a reasonable 30-day window to remediate the vulnerability before public disclosure.
- Qualifying security reports will be acknowledged on our public Hall of Fame.
Frequently Asked Support Topics
🐛 How do I report a bug or display glitch?
Please use our official support form above. Include your device type (Desktop/Mobile), operating system, browser, and a brief description of the steps to reproduce the issue. Screenshots or browser console logs are greatly appreciated!
🤖 Why did my matchmaking game start with an AI Bot?
If no human players enter the matchmaking queue within the countdown window, our matchmaking server assigns an intelligent bot to ensure you never have to wait. If you want human-only games, create a private room and invite friends!
💾 Are coin balances and shop avatars saved?
Your coins, unlocked avatars, sound settings, and win streaks are saved in your browser's persistent LocalStorage. Clearing your browser cookies/cache or using Incognito mode may reset these local values.
💡 Can I suggest new features or Sudoku variants?
We love community feedback! Select "Feature Suggestion" in our Google Form. Many of our features (including Sudoku Academy and Custom Sandbox) originated directly from community player requests.
🔒 What are your fair-play and anti-cheat policies?
We strictly prohibit automated solver scripts, browser macro extensions, or multi-accounting in ranked queues. Our WebSocket server performs real-time telemetry analysis on input timestamps to detect unnatural solving speeds.
🌐 Why does the multiplayer game fail on university Wi-Fi?
Certain campus or corporate firewalls restrict outbound WebSocket (WSS) traffic over non-standard ports. If you experience connection errors, try switching to a mobile hotspot or configuring your VPN to allow secure WebSockets.
🏆 How do I host a company or school Sudoku tournament?
We offer custom tournament tooling for corporate team-building events, STEM competitions, and puzzle clubs. Contact us through the form above under "Educational / Business Inquiry" and our team will provision custom private room codes and automated bracket tracking.
📱 Is there a native mobile app for iOS and Android?
Multiplayer Sudoku is fully optimized as a progressive web application (PWA) that installs directly from your mobile browser without eating device storage. We also maintain a native Android APK build for Google Play Store users with full offline solo puzzle support.
