On 6/9/18 I made a horse prop bet with BetOnline betting that Vino Rosso will "hit the board". He came in 4th place. The bet was graded as a loss because they define "hitting the board" as placing 1st, 2nd or 3rd. However every online search I do says that "hitting the board" means placing 1st, 2nd, 3rd AND 4th. I made an inquiry and got an email with their definition. When I responded to that email saying that I did multiple online searches for the definition and they all include 4th place and asked why they define it differently than everyone else I got no response. I am not a big horse better so I had to turn to the internet for help. I even took a screenshot of a page of a horse betting glossary and sent it to them in the email along with the link for the site. Can a sportsbook define a betting term differently? Or am I mistaken? I did several searches on different sites and got the same results. It's only a $500 bet but still if I won I want to get paid for it.
