Race the AI rival
A bot solves the same grid beside you in real time. It runs on-device, so it works with no connection at all — and it plays like a person: quick on the easy cells, slow on the hard ones, and it does make mistakes.
Sudoku with friends — and an AI rival that plays offline
Skudo gives you three ways to stop solving alone: race a real-time AI bot that runs on your own device, invite a friend to a private room for a head-to-head match, or team up in Co-op and fill one grid together.

Three ways to play together
Versus in a private room
Create a room, share the code, and both of you solve the same puzzle at the same time. Fastest correct grid wins.
Co-op on one grid
Same room, same board, one shared solution — you take turns filling cells and finish the puzzle as a team.
How a private room works
One player creates the room and gets a short code. Share it however you like — the invite link opens the app if it is installed, and shows a download page if it is not. Rooms need a connection; the AI rival does not.
Frequently asked questions
Can I play Sudoku with friends in Skudo?
Yes — create a private room, share the code, and play head-to-head or in Co-op mode where you solve one puzzle together.
What is the AI rival?
It is a bot opponent that solves the same puzzle alongside you in real time, and it runs entirely on your device — no internet needed. It plays at a human-like pace: faster on easy cells, slower on hard ones, and it makes mistakes.
Do both players need an account?
You can play against the AI rival with no account at all. Private rooms need you to be signed in so results can be attributed and synced.
Does the AI rival need the internet?
No — the bot runs entirely on your device, so you can race it on a plane or underground in the downloaded app.
