What Are Online Casino Bonuses?

Online casino bonuses are free money, bonus funds or the equivalent given to players by the casino to play real money online casino games. New players can get the best casino sign up offers at the casino sites we recommend. As a casino member, you get exclusive access to the latest casino bonuses, codes and promotion deals. There are different types of casino bonuses for instance free spins which are specifically used to play slots.

How the Best Casino Bonus Works

Most casino bonuses require players to make a minimum deposit in order to qualify for a bonus. And there are also no deposit bonuses which the casino give you free. Even those free bonuses come with terms, conditions and wagering requirements. The playthrough requirements for bonus funds vary from casino to casino. Let’s look at different casino bonus types.

Types of  Online Casino Bonus Offers and Promotions

Bonus hunting is easy with Best United States Casinos. We provide online gamblers with the best list of recommended casinos that have the best internet casino bonuses. Here you will find the most popular casino bonuses, bonuses for preferred games and more deposit offers. From game-specific bonuses, free chips, welcome deposit bonus, and VIP high roller bonuses. Each casino bonus has terms and conditions of use. We explore the variety of top online casino bonuses available to you below.

Online Casino No Deposit Bonus Offers

No deposit casino bonuses are free money- the most coveted gambling promotion. There is literally no deposit or any monetary wager required from the player in order to receive the bonus. It is a free bonus where the player gets credits or free spins to play real money games. Usually a no deposit bonus has limited use, i.e. you can only use it to play certain games. Furthermore this kind of bonus is often given to new players signing up to a casino.

Best Online Casino Welcome Bonus

The welcome bonus is also known as the sign-up bonus. You get this bonus upon your first deposit after creating a casino account. The best casino sign up deals come in different forms, from free spins, no deposit bonus or casino match deposit bonus. Online casino welcome bonuses are some of the biggest casino promotions in order to attract new players. The best online casino sign up bonus offers combine deposit match and free spins.

Online Casino Match Deposit Bonus

A casino deposit match bonus is a casino online bonus offer where the gambling site matches a percentage of your initial deposit dollar for dollar. The best online casino promotions match and double or even triple your deposit. Casino sites send out a promo code that you can use to claim your bonus cash.

Free Spins

Free spins are common online slots welcome bonus. Instead of being given an amount, you get a number of free spins of a fixed bet value on specified online slot machine games. Often free spins are for real money slot games, scratch cards, keno and bingo games. If you are an avid slots player, this is the perfect online casino promo for you.

Loyalty Casino Bonus

A loyalty bonus is a type of promotion or bonus given to regular players to reward their loyalty. Loyalty rewards are some of the best online casino bonus deals. Loyal players are rewarded with points every time they deposit and play. The loyalty points can be converted into extra cash to play more games. Your loyalty points can also get you into the VIP bonus program.

High Roller Casino Bonus

High roller casino bonuses offer the biggest casino bonuses for existing players. VIP exclusive casino bonuses for high roller players are for players who wager large amounts of money regularly. High roller bonuses have extra funds and low wagering requirements in comparison to the average player because they have already established a relationship with the casino.

Online Casino Bonus Codes

Casino bonus codes are the most common way in which casinos distribute casino bonuses. Gambling sites have a wide variety of bonuses at any given time and to make sure that casinos are claiming the right one they differentiate them by names or codes. Players will then input that code in the cashier section to claim the bonuses.

How Online Casino Match Deposit Bonuses Work

Most online casino bonuses use the deposit match percentage. It is a percentage of the deposit you place and which indicates the amount they will give you as a bonus. The deposit match percentage bonus will have a condition limit or cap of how much the casino will give you in bonuses. Let’s simplify with examples.

For instance if you deposit $200 and the online gambling site’s bonus is 100% up to $500. You will receive an additional $200 and have a total bankroll of $400.

The casino site offered a 100% match which means they will match your entire deposit dollar for dollar.

What about the $500 limit?  It means the maximum deposit that will be matched dollar for dollar is $500. So if you deposit $500 in the same 100% up to $500 offer, you will get an additional $500 for a total bankroll of $1,000. However if you deposit more, lets say $1,000 – you will only get an additional $500 for a total bankroll of $1,500.

Another condition that comes with bonuses, is the playthrough or the wagering requirements.

Understanding Online Casino Bonus Wagering Requirements

The deposit match percentage bonus will have a condition limit or cap of how much the casino will give you in bonuses. Let’s simplify with examples.

How to Find Best Online Casino Bonuses

There are many online gambling sites offering the latest casino bonus deals. Not all casino bonuses are worth it. The best online casino promotions have reasonable wagering and allow players to enjoy different casino games. Whether you are claiming a deposit bonus, free spins or free chips there are several factors to look out for.  Some casinos offer the best first deposit bonus while others have better VIP bonuses.

There are five main features to consider when you are looking for top online bonuses at gambling sites:

  1. Casino deposit method – your bonus amount will vary depending on whether you used a credit card, bitcoin or another casino payment method.
  2. Minimum Deposit – when it comes to casino promotions the amount of money you deposit will impact how much you get back. Each bonus deal has a minimum deposit requirement but the more you deposit the more you get back.
  3. Gambling game choices – casinos give a variety of bonuses which can only be used on specific games. Especially where a game contributes to perk / loyalty comp points. Slot games and a video poker game for example would have very different bonuses and comp point values.
  4. Read the fine print – you must check the terms and conditions of each bonus offer. Playthrough and wagering requirements work uniquely on each casino promotion.
  5. Mobile casino – using the mobile gambling app at your favorite casino site can get you exclusive bonus deals.

Online Casino Bonuses – FAQs

  • Should I always take an online casino bonus?

You should only take a bonus if it improves your gaming experience, you should not blindly take up any bonus offer. Understand the terms and conditions, some offers have a time limit imposed. Weigh the pros and cons against each other and take a considered decision. Suppose a bonus requires you to deposit $100 and you do not want to spend this amount, then do not take the bonus.

  • Can I cashout my winnings if I take a casino bonus?

You can cashout your winnings from a bonus, but there are some conditions. The first condition is that you have to be left with winnings after you complete the wagering requirement. You cannot cashout the winnings if you have only completed a part of the wagering requirement.

Online casinos impose a limit on the winnings that can be cashed out from bonuses. You cannot cashout more than this even if you have more winnings available.

  • The terms and conditions for bonus offers are long should I read them?

If you want to claim a bonus, you must read and understand the terms and conditions. If you do not read them, you can be in for a major disappointment. You may have created an impression in your mind that you deserve a certain amount after wagering the bonus. But the online casino may refer to a stated condition that you had not read and release a smaller amount or in the worst case no amount.

  • What are some things I should watch out for with casino bonuses?

The first thing you should check is whether the bonus is redeemable or non-redeemable. Redeemable rewards can be cashed out along with permissible winnings if the adequate balance is available after meeting the wagering requirements.

Non-redeemable bonuses are removed from the balance before computing the winnings. If you want to meet wagering requirements on any casino game other than slots, you will face a significantly increased amount. Most online casinos at least double the wagering requirements on other games.
