Guests and signed-in players can play together; only signed-in players are ranked.
Everyone joins in a waiting room first; the puzzle is revealed to all players at
the same moment when the host starts the game. Correct digits appear for everyone and score points:
the first digit is worth 100, the last one 10. A wrong digit costs half the current value.
