Now this is easy for those that like to just make their bets and forget about them, but for those that also like to make live bets this is way more complex, since they have no way to ignore those offers as they will be reminded about them by the casino in a regular basis.
Sport gambling has been fun all along before the initiation of the cash in feature. Which leaves gamblers like Op wondering over the best choice to take towards the end of a game. Imagine the joy he would have gotten after the suspense, and he ends up winning the game.
