In order to place a lay bet, click on the pink price next to the selection you're interested in.
Enter the stake price in the stake box. The amount that you risk in a lay bet is completely different from the back bet. In a lay bet, you would risk a potential amount that the backer would naturally win.
Similarly, the potential profit is the amount that the other side of the matched bet is risking. Put in simple words, for lay bets, your potential profit is the backer's stake.
If you are satisfied with your selection press the "Place Bets" button. When you click the "Place bets" button, you’ll have a bet offer that can be returned as unmatched, partially matched, or matched in full.
