bet365 is legal to players in the US aged 21+ and available to play in 7 states, with Colorado, New Jersey, Iowa, Kentucky, Ohio, Virginia, and Louisiana all accessible to residents in those areas.
Each-way means you are betting on two outcomes. The first is that the horse will win. The second is that it will finish in the places. Because of that, your bet is made up of two parts: the 'Win' and the 'Place'.
