Solve Together: Sudoku for Two

How to play

Solve Together is a two-player sudoku, a slow multiplayer puzzle you share with one other person: one grid you fill in together, one cell each per day, taking turns. It's made for couples, long-distance relationships, parents and grown kids, and friends who live apart.

HOW IT WORKS

Start a pair and send the invite code, a link, or a QR code. The pair lasts longer than any single puzzle, and you can be in several pairs at once: one with your significant other, one with your mom, one with a friend.

Then take turns. A move is one digit in any cell that wasn't filled in at the start. After your move, you wait for the other person, and for tomorrow. A classic puzzle takes weeks. That's the point: a few seconds a day with someone you care about, and a notification that means they're waiting on you.

Wrong digits aren't blocked. A wrong digit shows red on both screens until one of you fixes it on a later turn, so nobody can guess a cell in nine taps.

If a puzzle gets stuck, either of you can set it aside. It stays in your pair's history, and you can start a new one the same day.
