No Deposit Bonus

In the last 5 to 10 years, online casinos began to offer a no deposit bonus. A player needs an account for one of these, but this offer does not require they fund that account. For that reason, it’s also called a “Freeplay bonus”.

With the free play option, players are allowed to use house money to make some bets and try the casino games without risking their own cash. It’s a way to play with casino’s own money, with no risk of losing personal cash, with the added perk of having no obligations.

In a survey of over 50 online casinos, the best bonuses range between $15 and $900, but that does not mean the bigger offer is the better one. You’ll need to read the wagering requirements, sometimes known as the rollover requirements, to know what the conditions are. If it sounds too good to be true, it usually is.

Mobile casinos offer a No Deposit bonus as well. In my experience, these tend to be for smaller amounts of free cash. In one or two cases, the max Freeplay offer is even bigger. In a survey of 25 mobile casinos, I found them in the range of $5 to $1,250 (for Roxy Palace).

The deposit free bonus is one of the most popular and used at online casinos. These are called either no deposit bonus or instant play bonus. In either case, a player receives a small amount of promotional cash to enjoy real money gambling at the casino. This house money is meant to encourage players to test out the games and software. They hope players enjoy the experience and make a deposit.

Offers of free online casino bonus deposits tend to be small, ranging from $5 to $50. Some sites have been known to offer much bigger payouts for sign-ups. The important thing is you don’t have to make a deposit in order to use the promotion. These bonus offers come with different wagering requirements. These can be as low as 1x the bonus, but it usually involves 20x to 50x the bonus received.

Best No Deposit Bonus

The best no-deposit bonus lets a player bet with house money before risking their own cash. Casinos give no-deposit bonuses to players who register for a new account, offering free chips or small payment to your casino account as soon as you sign up.

Cafe Casino has the best no-deposit bonus for US players: a $10 free chip with a max cashout of $125. Slots.lv also has a great $22 no-deposit bonus for players in the USA. It is subject to 100x playthrough, with a maximum withdrawal of $125 on winnings. Make sure to use coupon code SLOTS22 to redeem this offer.

Casino Deposit Bonuses

When players make their first deposit at an online casino, it triggers the deposit bonus. With that initial deposit and sometimes up to the first 3 payments, the online casino will add free cash to your account; they match the amount you pay. These are often referred to as a Sign-Up bonus. To find the best online casino sign up bonuses, see what the match rate is and compare it to the others, using the steps below as a guide.

The match rate on deposit bonuses are very important. If the online casino matches $1 to $1, that is called a 100% bonus. If a casino matches $1 to $2, that’s a 200% bonus. If you have to contribute $2 to get $1 in bonus cash, that’s a 50% bonus. One-hundred percent is fairly standard, so those which offer two-hundred percent are making a nice offer. The 50% bonus is usually for additional deposits.

Online casinos that offer multiple deposit bonuses often front-load the first payment. That is, you might receive a $500, 100% bonus offer. If you deposit $500, your account will show $1,000. If you receive cash on the second deposit, this might be $500 at 50%, meaning you would need to deposit a full $1,000 to receive $500 in bonus cash. The first deposit is usually the highest.

The first deposit bonus a casino offers is important to attract players. This is your first interaction with a casino. If you are test-driving a number of different brands, then the wagering requirement is vital. Although, not every welcome bonus is a first deposit bonus. Be sure to check out the details before making your first deposit.

Many gamblers plan their payments to max out the deposit bonus offer. It makes sense to do so if it’s affordable. In the scenario above, a gambler who intended to fund their account with $1,000 of their own cash might only deposit $500 in the first payment. They would be able to get more bonus cash by making two deposits, instead of only one. Read the terms and conditions closely in order to know how to get the most out of the online casino bonus.

Best Deposit Bonus

Finding the best deposit bonus can be useful for players wanting to max-out their bankroll. Slots.lv has the best deposit bonus for US players, giving them up to $5,000 extra over their first 5 deposits. Cafe Casino also has a great deposit bonus, offering players up to 500% up to $5,000 in Welcome Bonus offers and a $10 Free Chip to get you playing right away!

Reload Bonus

At a time, online casinos did not offer a free cash bonus for reloads. It’s becoming more common these days, and it was long overdue. A reload bonus is an ongoing offer for loyal customers who continuously make deposits into their account. The idea is that the returning players’ cash is just as valuable as the new players. Also, these members have shown loyalty and should be rewarded. Many of the same terms and conditions that apply to these bonuses are not always as large as a new customer’s bonus.

It should be mentioned the reloads are in addition to the VIP rewards program. Online casinos, as well as mobile casinos, have a rewards program for ongoing customers. This is like the slots club at a land-based casino. The more you play, the more money perks you receive. For those unfamiliar with casino club cards, it’s like the rewards program on your credit card. The reload bonus is an enhancement to these other rewards, which is one reason it’s often not as substantial as the initial casino deposit bonus.

Best Reload Bonus

A reload bonus given to continuing players for their loyalty. Several different types of reload bonus exist, including a weekly, a monthly, and a standalone reload bonuses. BetOnline Casino has the best reload bonus of $1000 USA players who use the bonus code CASINO25. BetOnline Casino’s sister site, Sportbetting.ag has an equal $1000 reload bonus for US players.

Game-Specific Bonus

You probably know already that slot machines have higher house edge than blackjack and video poker, and usually a higher house edge than craps and baccarat. When making an offer, a slots player would be getting a worse deal if they were offered the same size bonus as a blackjack player. For that reason, the online casino bonus for specific games is often offered to players.

These take two forms

Game Restrictions – A player might be restricted to a handful of games they can play, or even slots-only requirements. For instance, you might learn you have to play the slots with your deposit bonus or Freeplay offer. If so, playing blackjack does not meet the requirement. For online casino slots, this is also commonly known as a Free Spins Bonus; as explained below.

Any Game – A player might be able to play any game they want, but the play-through requirement might be different for two different games. It’s not uncommon to see slot machines fulfill the wagering requirement at 100% while blackjack fulfills the requirement at a 10% rate. In this case, you would have to wager 10 times more money on blackjack than you would on slot machines.

Instead of offering an online casino bonus, the player is offered free spins on video slot machines. The first site to do this was Royal Vegas Casino, which offered 1,600 free spins instead of a welcome bonus.

It is easier for a player when an online casino offers a free spins bonus. Here are some of the advantages of this bonus:

As time passes, expect the free spins bonus will become an industry standard, at least for legitimate online casinos. Be sure to look for the free spins bonus at any of the best online casinos.

Best Games Bonus

A games-specific bonus targets one game or specific types of games. Categories might be slot machines, video poker, table games, or even a specific table game (like blackjack). Las Vegas USA Casino has the best games bonus for US residents. Their promotion is a $3,000 table games-specific bonus table games and video poker, but you need to use the bonus codes 150BONUS and IDBLASVEGAS. No maximum winnings apply, but some table games are restricted.

If playing on-the-go is your thing, Bovada Casino has the best mobile casino games and bonuses. Their game Jackpot Piñatas is a mobile-exclusive game featuring a bonus that pays 200x your initial bet, free spins, and a progressive jackpot.

Online Casino VIP Rewards Programs

In addition to these bonus options, some online casinos offer VIP program. These rewards are exclusive to the casino sites loyal customers, rewarding them with extra benefits, incentives, and rewards. With these VIP rewards programs, players can earn points while they play real money casino games.

Common rewards for VIP member at an online casino are:

Online Casino Bonus Types

Before players consider claiming a bonus offer, they need to know which types of online casino bonuses are available. Below is a quick scorecard of what you can expect.

• Deposit Bonus

  Offered to players who make a deposit into their casino account. This is the best online casino bonus, as they offer the most money to players.

• Freeplay Bonus

  Offered to players who register an account at an online casino. They do not have to fund that account in order to claim the bonus. These are usually much smaller than the deposit bonus.

• Reload Bonus

  These are for loyal and recurring players who have cleared their deposit bonus requirements already. These are a reward for loyalty after each time a player makes a deposit.

• No Deposit Bonus

  Players that join an online casino are often given a no deposit bonus so that they can start playing right away, without having to make a deposit first. These are great ways to win extra cash before making the first deposit.

• Games-Specific Bonus

  Terms and condition which restrict play to the games with the worst odds. It also describes a special one-time bonus offered to promote a new game.

How to Use a Casino Bonus Code

Players who’ve never used a casino bonus code should use the steps below as a guide. The process is quick and easy. The main challenge is finding the best casino bonus code information for your situation. Use your personal dashboard or player menu to find the promo codes on the official site.

A deposit bonus code is a specific type of promotion. It is available when you make a deposit to your account. These codes are offered either as a first deposit bonus or as a reload bonus. In either case, the player receives an incentive to fund their account.

Free play bonus codes are also available. Two types of free play codes exist. One type is available when you register. This type, a no deposit bonus code, allows you to play with real money without making a deposit. The second activates when you make a deposit. The casino’s cashier adds the free play money to your account on top of any other bonuses you’re received. In either case, you’ll redeem free play promo codes on the same sub-page in your player dashboard as the codes described above.

What to Look for in a Bonus

Those are the broad online casino bonus types that players can receive. Deciding which are best is not a matter of finding the biggest payouts, though. Several factors need to be considered.

Read a casino’s terms and conditions, because other requirements are likely to be in effect. The devil is in the details, so a seemingly great offer might not be worth much. Avoid sites which are not upfront with their bonus offers, because they likely do the same in other areas.

Finding the Best Casino Bonuses

Readers might have guessed by now that finding the best online casino bonus is not easy. To find the best casino bonuses, you have to read more than the sales copy that the sites advertise. You’ll need to get down into the casino’s “Terms & Conditions” page for the wagering requirements. You might need to read through the FAQ for clarification, or even communicate with customer support on live chat. Get the information correct before making a decision.

It helps to have a trusted review site or two to get reliable, accessible information.
