SudoSquad lets you create private Sudoku rooms, invite friends, and solve the same board at the same time. This is the fastest path if you want friendly competition without open matchmaking.
Hosts control the room, players join with a code or secure invite, and results settle once every run is complete. It works well for casual groups, school circles, and competitive friend matches.
