USA Casino Bonus Terms Overview

Before you accept the biggest bonus code, make sure you understand the fine print. More importantly, check the bonus game weighting and supply the coupon code for the bonus. Bonus players often ‘overlook’ the wagering requirements and the max bet. The max bet is the maximum permissible wager per spin the casino allows you to bet on the slot. That’s if a player accepts the casino’s biggest bonus on deposit.

What is the wagering requirement? It’s the number of times you have to roll over the bonus before you can cash out your wins. If the play-through of the biggest bonus is 30x. It means that you must wager bonus funds 30x the deposit and the sum of the bonus. Only then can you put in a request for the casino to process your winnings.

The bonus weighting says that online slot machines count 100%. John can play any slots for real money in the casino’s slots library. Unless the online casino specifies otherwise. If the rollover of the bonus is 30xd+b, how much cash must John bet? The figure looks like this: 30x$1,000+$2,000=$90,000. John must place bets to the value of $90,000 before the casino clears his winnings.
