Types of Casino Bonuses and Promotions
To maximize the offerings of top online casinos, leveraging bonuses and promotions is essential. While games are the primary draw of these platforms, bonuses significantly enhance the overall experience.
What is a casino bonus? It’s a credit added to your account, allowing you to play online casino games without dipping into your existing funds. For example, registering a new casino account with our exclusive deposit bonus code and claiming $100 provides credited funds for real money gaming. Once you meet the specified wagering requirements, all accumulated winnings are yours to keep.
In essence, casino bonuses can transform your gaming experience, turning modest opportunities into substantial rewards. Their critical role makes them an integral part of online gambling sites, ensuring you get maximum value from your time online.
How to Choose the Best Casino Bonuses
You understand how online casinos offer bonuses, the various promotions available, and how to claim them. Before enhancing your online experience, consider the following key points:
- Select Legal Offers from Licensed Online Casinos: The casino bonuses recommended in this guide are legitimate and provide the best value. Alternatively, you can explore bonuses from social casinos for casual entertainment. We recommend using our Stake.us bonus code.
- Look for Reasonable Wagering Requirements: While accumulative bonus points can be tempting, you must unlock them. If the threshold is too high or the game requirements are unrealistic, the offer may not be worth claiming. Therefore, choose promotions with appropriate wagering conditions.
- Understand Your Responsibilities: Before you start playing, make sure to read the terms. Even missing one requirement could result in the forfeiture of your bonus.
- Search for Bonus Codes: Casino.com offers some of the best new casino promotions, many of which require codes. Please use our promo codes whenever possible to receive exclusive offers and maximum value.
- Enjoy Responsibly, Avoid Chasing Bonuses: Searching the internet for the best casino bonuses is worthwhile, but do not risk losses that exceed what you can afford in pursuit of rewards.
Casino Bonus Terms and Conditions
Whether it’s a welcome bonus or free spins offer, each promotion has specific terms and conditions. These conditions, commonly referred to as “wagering requirements,” must be met in order to unlock the associated rewards.
In simple terms, if you fail to meet the wagering requirements before, during, or after claiming the offer, you will not be able to receive the bonus. Before diving into the wagering requirements of the best US casino bonuses, let’s quickly look at an example to illustrate the expected situation.
Example of Casino A Bonus Offer: Deposit funds into your new online casino account to receive 50 free spins. The minimum deposit is $10, and the maximum cash payout is $50. The wagering requirement is 5 times the bonus amount, and the free spins are valid for 10 days.
The wagering requirements for this offer include:
- The welcome package includes 50 free spins. You must be a new player registering for an online casino account to claim it.
- Your initial deposit must be at least $10.
- The maximum winnings from your spins is capped at $50.
- Withdrawals are not allowed while holding an active bonus, and you must wager the bonus amount 5 times within 10 days.
This is a basic example of how most bonuses work. While there are some universal terms across promotions, it is crucial to recognize that each casino bonus has its unique wagering requirements. With that in mind, here are the key wagering requirements you should understand when learning about online casino bonuses:
- Minimum Qualifying Deposit: Each deposit bonus offer comes with a minimum deposit requirement. Generally, the minimum deposit for welcome bonuses ranges from $5 to $20, while reload bonuses typically require deposits of $10 to $20.
- Deposit Methods: Certain promotions may not be available if specific payment methods are used. For instance, some recommended New Jersey online casino bonuses have restrictions regarding deposits made with credit cards. Failure to comply with such terms may result in losing eligibility for new player promotions, loyalty program rewards, or substantial bonuses for existing customers.

- Casino Bonus Codes: Some of the most enticing online casino promotions require activation codes to initiate. These codes are often related to the online casino registration bonuses and may need to be entered during registration or before making a deposit. Remember that ongoing promotions, such as reload bonuses and loyalty program rewards, may also require specific activation codes. Use our reviews to compare the latest casino bonuses and identify offers that require promotional codes for your state.
- Wagering Requirements/Game Counts: Each offer comes with terms and conditions, usually referred to as wagering requirements, that must be adhered to before, during, and after claiming an online casino bonus. These conditions include the following notes:
- Game Contribution: Different games contribute differently to your wagering goals, with some games counting fully while others do not. The contribution weight varies, indicating the proportion of each bet that counts towards clearing the bonus. For instance, games with a contribution weight of 100% mean every bet contributes towards the wagering goals, while games with a weight of 50% mean only half of each bet contributes. The best online casino bonuses in the US generally credit rewards while you play any game, with online slots typically having a 100% contribution weight. Games like blackjack and roulette usually carry contribution weights of 10% and 50%.
- Time Limits: Even the most generous casino bonuses come with expiration dates and redemption timeframes (i.e., achieving the wagering goals). Failing to meet wagering requirements within the specified timeframe may result in the forfeiture of the entire bonus. New casino and registration bonus game deadlines are typically longer, while no-wagering bonuses usually have shorter validity.
- Bonus Caps: While winning unlimited amounts of bonus money is ideal, there are usually caps on the use of bonus points. Make sure to consider this before starting to play.
- State Restrictions: Due to varying regulatory laws on online gambling sites across states, casino bonuses in New Jersey may differ from those in other states. State regulations dictate what is permitted, leading to differences in rules across states like Michigan, New Jersey, and Pennsylvania. Our guide will provide a comprehensive overview of gambling laws and the services offered by operators in legal online casino states.
- Game Restrictions: Participation in specific casino games may affect your ability to claim and/or cash out your bonuses. For example, certain bonuses may not apply to live dealer games. To avoid disappointment, be sure to read the terms and conditions carefully before placing any bets.
