What does 3Way mean?

In 3Way bets, there are three possible outcomes and you have to pick the right one. The ordinary football bet – win, draw, or loss – is a classic 3Way-bet. For example, Bayern-Munich plays Manchester United - 1, X, 2.
3Way bets usually refer to the result at the end of the regular playing time (exceptions are stated in the General Terms and Conditions or are announced as they occur).
