I have a local its 1betvegas.com I dont use any offshore or foreign sites bc i dont trust them, but go to parlay on your tab and see if there is a spot anyone on the site to put open on. my screen when i click on parlay at the top left it says add open with a blank to put 1,2,3,4,5 any of those numbers in, and if u put 5 after u have selected one it means you have a 6 game parlay. Try going to your main site and seeing if there is a spot for " Fill Open" that would also indicate ur able to do it. I love open bets. didnt figure it out til the end of football season, but Hell 1 pick a day for 5 days and u can hedge it for guaranteed $100's of dollars. Good luck finding one pry3abet
