How to play

Find out how Daily, Ghost Race, multiplayer and free practice work in Sudoku Raven, and choose the game mode that suits you.

Daily puzzles

Each day offers four difficulties per variant. Play the daily challenges, build a streak and compare times on the leaderboard. You can begin as a guest; an account lets you save your results.

Ghost Race

Race a recording of a player’s first attempt on a puzzle you have not played, when one is available, or race the computer. Choose a difficulty and ghost tempo. Watch the opponent’s progress while solving your own board.

Multiplayer with friends

Choose a variant and difficulty, create a room and share its room link. Race on individual boards, solve together in Co-op or play team against team. Automatic matchmaking finds players with the same variant and difficulty, for both classic Sudoku and Killer.

Free practice with hints

Practise without ranking or a race clock. The guide first reveals a technique, then its supporting cells and finally the full reasoning. Show candidates or let the guide apply a step. Practice boards are not saved when you leave the page.

How do I link directly to a variant?

Use a direct link to Killer Sudoku or Classic Sudoku. The link opens game selection with the correct variant selected. For a specific difficulty, use a path such as /killer/hard. To play in the same room, create the room first and share its room link.
