A wager requirement is a coefficient that is involved in the gaming when online gamblers activate a casino bonus – Bonus credits, Deposit and No Deposit Free Spins. The parameter (25x – 100x) shows the sum you have to wager playing the same slot game after you’ve used the bonus. If not, you won’t get to withdraw your winnings. Suppose, you received 50 free spins that come with the wagering requirement of 35x. With these bonuses you have won $5. Then, work out the play-through coefficient by the formula: 35x$5=$175. Carry on with gambling until the calculated sum ($175) has been bet.
