You will notice that there is often a limit for your bet per spin when you are meeting the wagering requirements for a bonus. At sports betting websites, this limit applies to the odds of the bets you are making when using bonus funds. This is usually done so that players/punters do not take advantage of the casino and sportsbooks offers. If you attempt to bet above the set limit while you are wagering a bonus, this will often result in losing all of the bonus and the winnings accumulated thanks to it.
