Online Casino Sign Up Bonus Terms & Conditions

Bonuses and various promotions are what sets online casino sites apart from their brick-and-mortar counterparts. They encourage new players to sign up and make their first deposit by giving them an initial boost with deposit match or free spins.

But, as enticing as they may seem, these bonuses come with specific terms and conditions that you should understand. Let’s go over some of the key terms you should know when selecting the perfect sign up bonus for you.

Minimum Qualifying Deposit

The minimum qualifying deposit refers to the smallest amount you need to deposit to become eligible for the sign up bonus. Online casinos set different minimum limits, so it’s important to check what this amount is.

Deposit Methods for Bonuses

While most online casinos offer a variety of deposit methods, not all are eligible for the sign up bonus. For example, some casinos exclude deposits made through certain e-wallets like Neteller or Skrill from bonus eligibility.

Caps on Winnings

Some online casinos put a cap or limit on the maximum amount you can win using the sign up bonus. It means if you hit a jackpot, there might be a ceiling on the amount of bonus-derived winnings you can withdraw.

Wagering Requirements / Playthrough

Wagering requirements, also known as playthrough requirements, indicate the number of times you must wager the bonus amount before you can withdraw the winnings derived from it.

Game Contributions to Wagering Requirements

Different casino games contribute differently towards meeting the wagering requirements. For example, slots might contribute 100%, meaning every dollar wagered counts towards the playthrough, while table games like real money roulette or blackjack might only contribute 10% or not at all.

Time Limit for Bonuses

Online casino welcome bonuses usually come with a time limit within which you need to use the bonus and meet the wagering requirements.

Game Restrictions with Bonuses

Not all games may be eligible to be played using the sign up bonus. Some games might be entirely excluded, while others might count less towards the wagering requirements.

Bonus Codes in Casino Bonuses

Some casinos require a bonus code to claim the sign up bonus. These codes are either provided by the casino on their promotions page or sent via email. Remember to enter the bonus code at the time of deposit to successfully claim your bonus.

A reputable online casino welcome bonus is offered by licensed casinos. They offer independently audited games and genuine bonuses. Always ensure to verify these features before claiming a bonus.

For your protection, our team only reviews above-board online casinos. If you choose to deviate from our top picks, always check the bottom of your site’s homepage for a certification or badge.

What is the Best Casino Bonus for New Customers?

Slots.lv offers the best online casino signup bonuses for new customers, with options tailored for both crypto and card users. For crypto players, Slots.lv provides a 200% match bonus up to $3,000 on your first deposit, along with 30 free spins.

Which Online Casino Has the Biggest Welcome Bonus?

Mirax has the biggest online casino bonus. They’ll match your initial deposit up to 5 BTC, and the 150 free spins make this deal taste even sweeter.

Bitstarz is a close second to Mirax, but you’ll have the opportunity to score 5 BTC with your first 4 deposits instead of getting all the deposit bonus money upfront. 

What Online Casino Gives You Free Money for Signing Up?

All online casinos on our list give you free money for signing up and making a deposit. So, you don’t get free money only for signing up – you also have to meet certain conditions first.

Alternatively, no deposit bonus casinos can offer you a small free chip or free spins to try and win free money after you register, but these offers are not as valuable as the other best welcome bonuses that require a minimum deposit.

How Should I Pick the Right Casino Sign Up Bonus for Me?

Selecting the right mobile casino sign up bonus depends on your budget and preferred casino games. However, for most players, Slots.lv offers a versatile bonus that suits various needs.
