What To Keep In Mind When Claiming An Online Bonus

  • Deposit minimum: When claiming an online casino bonus, be sure you know the minimum deposit required. If you deposit too little, you do not earn the offer.
  • Bonus code details: Does the offer you are claiming require a promo code? If so, be sure you enter the code correctly to claim the deal. This includes any numbers and letters, capital, or lowercase. 
  • Rollover requirements: Review all rollover requirements before claiming a deal. This will be the deposit plus bonus amount multiplied by a certain number of times. You must wager the deposit + Bonus amount so many times before you are allowed to cash out.
  • Game specifications: Be sure to review the bonus deal and check for game specifications. Some deals require you use the bonus cash on specific game types or titles.
  • Time frame to clear the offer: How long do you have to clear the bonus? Read the online casino promotion terms and conditions to fully understand how much time you have to complete the rollover requirements.

Casino Bonuses Rollover Explained

The bonus rollover is the amount you must wager at a casino to make a withdrawal after claiming a bonus deal.

Let’s say you took advantage of a 100% online casino welcome bonus worth up to $100. You deposited $100, so you earned $100 in bonus cash, for a total of $200.

For this deal, the wagering requirements are the bonus + deposit amount wagered, times 25. So, you need to wager $100 (Deposit) + $100 (Bonus Cash) X 25 ($200 x 25 = $5000). You would need to wager $5,000 before you can make a withdrawal.

Bonus Wagering Requirements Explained

The bonus wagering requirements are the terms you must meet to complete a bonus deal. In the example above, the wagering requirement is 25x. When claiming a bonus, you will need to review the wagering requirements in detail.

For our above explanation, the requirements include the deposit plus the bonus amount. Most online casinos figure their offers in this manner. However, some casino bonuses only require the deposit amount to be rolled over from time to time. 

When Should You Claim An Online Casino Bonus?

There are certain instances when you should claim a casino bonus and others when you would probably be better off skipping out on an offer available to you.

Learning when to claim the best casino bonus offer is helpful as you start to play more at an online casino.

  • When signing up at a new online casino: This is a prime time to take advantage of casino deals. You will earn more cashback and have lower rollover requirements.  
  • When the rollover amount is low: When a deal offers low rollover, take it! This helps you to clear the offer faster!
  • When you want to build a larger bankroll: Signing up for online casino promotions will help you build a larger bankroll as it adds to your initial deposit

When You Shouldn’t Claim A Bonus At An Online Casino

  • The rollover amount is extremely high: The standard rollover for online casinos is around 30-40x – use that as the average. If a deal has a rollover requirement higher than 40x, it should be avoided.
  • You won’t have time to clear the bonus: If you don’t play any of the games needed to clear the wagering requirements, there is no point in claiming the deal. You will not have time to clear the bonus.

When it comes to claiming the top casino bonuses and promotions, look for the best casino deals you can find.

There are many different types of online casino bonuses to choose from, whether you are a new player at a site or a returning member.
