1.  When you open a duel, you start.
  2.  Your duel is then shown in the duel overview.
  3.  Other players can join your duel immediately or later.
  4.  When another player joins your game, they will play the same game set.
  5.  If you were faster or the other player joined later, the duel will be shown as undecided when you see the results page.

Why can't I see the opponent(s)?

If nobody has joined the duel by the time you see the results page, no opponent is shown. On the results page it will say: "Waiting for opponent". Please be patient: an opponent should join soon!

How do I know if I won or lost?

As an upgraded player you can view your duel results on the finished duels page. We advise practice players to enable the email notification settings for won and lost duels.
