We will add interactive tutorial soon, but currently there is information in the bet slip, that states: Back (bet for) and Lay (bet against) the outcome you've chosen. The easiest way to recognize what's happening is to watch out for the colors - red means you are betting against the outcome and green means you are betting that it will happen.
That still wasn't helpful and I saw all that on the site. Still not helpful. If there are two teams playing in a foreign country then who is the home team and who is the away team? Green and red and home and away do not tell me which team I am betting on. I wanted to bet on Germany and I thought I did. Surprise, surprise! I didn't. Get it?
