Welcome to

sudokufriends is a free, browser-based sudoku platform built for players who believe puzzles are better when shared. With classic 9x9 and larger 16x16 puzzles, real-time multiplayer rooms, and zero signup required, it's the easiest way to enjoy sudoku with anyone, anywhere.

Our Mission

sudokufriends exists to bring people together through the joy of puzzle-solving. While there are many sudoku apps out there, most of them are built for solo play. sudokufriends is different. It was designed from the ground up to make sudoku a social experience, so you can share the thrill of cracking a tough puzzle with the people you care about.

What sudokufriends Offers

Real-Time Multiplayer

Create a private room, share the link, and solve the same puzzle together in real time. Whether you're sitting side by side or on opposite sides of the world, co-op mode lets you collaborate on a puzzle while versus mode turns it into a friendly race. No account needed, no download required.

Puzzles for Every Skill Level

From beginners to experts, there's always a challenge waiting. Classic 9x9 sudoku comes in six difficulty levels (Easy, Medium, Advanced, Hard, Expert, Insane), and 16x16 sudoku (also known as hexadoku) offers four difficulty levels. Every puzzle type and difficulty is available in multiplayer.

Smart Tools That Help, Not Distract

Features like pencil marks and hints are built in to support your solving experience. They're ready when you need them but never get in the way of the pure sudoku challenge.

Clean, Focused Design

The interface is simple, fast, and distraction-free. It works beautifully on both desktop and mobile, so nothing stands between you and the puzzle.
