Choose by workflow
The shared task is solving a Sudoku grid, but the setting changes the choice. Arena offers solo play, a duel or a nearby group of up to eight players, with room-code or QR invitations and shared progress. Sudoku.com's browser game offers Classic and Killer puzzles, daily challenges, notes, undo and hints. It is a convenient choice when you want to open a puzzle on a computer without installing an app. Arena fits a table of friends who each have a phone and want a shared match.
