A wagering requirement is a coefficient that only applies to the gambling process when online gamblers receive a casino bonus – No Deposit or Deposit Free Spins, Match-ups. The parameter (25x – 80x) establishes the amount you need to wager playing the same slot game after you’ve used the bonus. If you don’t do it you won’t have a right to request what you have won even if you win some. Let’s assume you were rewarded with 20 No Deposit or Deposit Free Spins with the wager that equals 15x. You have played through the bonuses and you have won $20. You will get the wagering requirement: 15x$20=$300. You have to keep gambling till the calculated amount has been spent.
