Race Mode Flow
The same solving ideas apply in Sudoku Race, but the setup is live:
- Create a private lobby and invite a friend.
- The guest taps Join lobby, both players mark ready, and the host starts.
- Before the start, the guest can leave and the host can kick the guest to reopen the slot.
- Once the race is live, the first correct finish wins.
