An Each Way (E/W) bet is basically two bets - one bet is for the horse to win, the other is for the horse to place.
Because it is two bets, you have to double your stake. You will receive a return on your bet if your selection wins but also if it places. The place part of the bet will always be a fraction of the odds you have taken, usually 1/4 or 1/5
Basically this means how many places we pay out on and this can differ from race to race. At the bottom of each race on site you will see what the place terms are.
If the E/W check box is not clickable, it means that Each Way is not available for that sport.
