Pinnacle is widely considered the best sportsbook online and it also offers the best bonus. It is not about any percentage of your deposit: by betting at Pinnacle, you are giving yourself a bonus for life. Pinnacle generally has the highest odds available. Where your ordinary bookie offers you 1.8-1.8 (or -125/-125), Pinnacle often goes up to 1.96-1.96 (or -104/-104). Pinnacle welcomes even the serious winning players and never closes or limits their accounts. Considering the super fast payouts, there really is no reason to keep playing for lower odds.
You can see your current sports on the left side of this page. You can edit the name of the sport (if you have any bets on that sport in the database, the name of the sport will be automatically changed in these bets). You can remove a sport from the list - but only if you don't have any previous wagers placed on that sport.
You can add a new sport to your list from the table of already recognized sports on the right side or just freely fill the name of the new sport into the simple form.
