BetOpenly.com is a bettor to bettor marketplace! We remove the house, remove the 10-20% juice/fees/hold/width. All users can create their own lines and odds, and connect directly with someone they know safely and securely. We also have Contests, Giveaways, Pools and DFS (Daily Fantasy Sports). Always create the EXACT bet you want! Don’t overthink it. And only take bets, if the team/spread/details are exactly what you want! We are Bettor To Bettor / Person To Person (P2P) Social Betting. INSTANT is the name of our Daily Fantasy Sports (DFS) Player Props. Where can I find you 100 page rule book? You can’t! Our rules are simpler than all sports books. All pending bets are ACTION. Meaning if they are pending, once an event starts, we settle the bet with the final score, even if that final score is, for example, after 6 innings in MLB. That includes Totals, Runline, (different from most books) etc. The goal is simplicity. The goal is never to give anyone an advantage. We wanted to stop people from having cancelled bets where their NYY -1.5 is rained out in the 7th and they are up 5-0. Or their Over 7.5 bet cancels when it's 6-4 in the 5th inning. This to us is more simple and fair. What is the minimum bet? $1 Instant and $10 Person to Person (P2P). Can I take a fraction of a bet? Absolutely, as little as $10 of any bet. What happens if my bet isn’t taken? You are fully refunded at the start of the event. What happens if part of my bet isn’t taken? You are refunded any untaken amount, and the amount taken is pending. Welcome! We are in the business of saving ALL our users $.
