If the prediction remains the same as the group stage as what the name of the competition "Euro 1x2", logically the selection is valid for 90 minutes of play only. It is not possible for extra time and penalties unless there will be a change for the Knock Out with more choices to select for the Knock Out (e.g 1 or x or 2 or ET or Penalties).
Regular group stage matches are different because they end after 90 minutes no matter the result. During the knockout stage there has to be a winner and a team must proceed in the competition. That's why I want an official statement from FortuneJack about the rules in KO matches. The terms do mention that we are predicting the full-time results, but just to be certain.
Anyway, do you need to place a bet for the EURO1x2 competition?
You don't have to bet on the matches. The competition is free for everyone.
