Best Promo Code Casinos

Online casino promo codes are one of the best ways for casinos to find new gamblers - codes are easy to use, straightforward and provide a certain immediate sense of gratification for the gambler who can redeem a voucher code for some additional bonuses.

Though these casino codes are popular, it doesn’t necessarily mean every online casino promoting its bonus codes is automatically valuable. Here, we’ll highlight some of the factors that help to determine which online casino has the best promo codes and overall gambling quality.


Sadly, there are many fraudsters out there pretending to offer online casino free bonus codes, each more lucrative than the other. Luckily, gamblers can safeguard their data and money by signing up on legitimately licensed casino sites - sites that have been checked and verified by governmental authorities.

This may not sound fun, but it’s a crucial step that guarantees data and money are kept away from fraudsters or hackers. Hundreds of licensed reputable online casinos issue bonus codes regularly, so there’s no need to go hunting for random casino sites, hoping to find better online casino codes.

Terms and conditions

The most important factor that entirely answers the question of which casino bonus code is the best lies in terms and conditions. All casinos apply some restrictions on their bonus codes to ensure the whole gambling site is kept safe and, naturally, the online casino maintains its profitability.

Casino bonus codes may have various restrictions, including wagering requirements that may easily go up to 50x (or even higher). Lower wagering requirements are always preferred, so the best promo code for online casino enjoyment is the one with the best playthrough terms.

Gamblers should cautiously read through the terms that are attached to the online casino promo code and consider whether the offered terms are aligned with their bankroll and gambling goals.

Payment methods

Bonus codes for online casinos get unlocked after a successful deposit, but a deposit can only be successful as long as the player has various great payment methods at their disposal. Most online casinos allow bank transfers, debit and credit card payments, cryptocurrency payments and electronic wallet payments (such as Skrill or PayPal).

When using casino promotion codes, gamblers should also note the required minimum deposit, since it may vary depending on the casino and the bonus code: some bonus codes may allow the lowest possible deposit, whereas others may require higher payments.

Customer support

9 times out of 10, the casino promo code can be activated via a dedicated field, but sometimes, it can only be activated by reaching out to customer support and sharing the bonus code with the casino’s team, who can then activate the bonus.

That makes having a skilled customer support team that much more important when choosing a suitable casino. Top online casinos should offer 24/7 customer support, especially when sharing bonus codes that must be activated via the support channel.

Tips for Safe Use of Online Casino Bonus Codes

What is a Casino Bonus Code?

Online casino bonus code is a special voucher code that redeems a certain bonus for the customer. In a way, it’s similar to discount codes or vouchers usually offered by online stores: if the customer makes a purchase (deposits money to the casino account), the company offers a discount or a promotion as a special gift.

Many casinos issue bonus codes, especially to new gamblers who make their first deposits. Sometimes, these bonus codes carry another purpose: they make it easier for the casino to activate bonus offers only for those gamblers who want to redeem a special offer (since not all gamblers may desire that). In other words, bonus codes make it easier for the company to manage their promotional offers.

It’s also possible to find free online casino bonus codes that are meant just for newly registered players - these may unlock a small symbolic bonus offer or a few free spins. First deposit bonus codes tend to activate much larger bonuses that may reach up to several hundred dollars.

How do Casino Bonus Codes Work?

Online casino bonus codes are simple and straightforward to use. In most cases, the process looks something like this:

  1. Finding the bonus code from Online CasinoRank comparison listings or straight from the casino’s website. If there are some significant bonus codes available, the casino usually lists the codes on its promotions page.
  2. Registering on the casino site. On most casino sites, this process shouldn’t take more than a few minutes, since it only involves using your email address, and password and entering a few details.
  3. Making the first deposit. This is the most important step of using bonus codes - the received promo code must be entered during the sign-up on an appropriate field (it’s always nicely highlighted on the deposit page).
  4. After confirming the payment and heading back to the casino, the bonus code should be activated and the related bonus should be deposited in the gamblers’ casino account. If the bonus code redeemed free spins, those are found inside the respective slot game.

Advantages and Disadvantages of Casino Bonus Codes

Most gamblers will find many perks for using bonus codes, but that doesn’t necessarily mean every player will need to use bonus codes or may even desire them. Here are some of the main pros and cons to consider before deciding on whether or not bonus codes are worth using.

Advantages of Bonus Codes

There are many advantages to using casino bonus codes: after all, a free bonus code unlocks a remarkable gift that can be used for additional gameplay. There’s a big difference between gambling with 100 dollars versus using a free bonus code for an additional 100 dollars, ending up with a balance of 200 dollars. Thus, the main benefit of using casino bonus codes is the advantage players get on their bankroll.

Often, casino bonus codes activate free spins on new slot games people may not have noticed yet - it’s a great promotional tool that helps to get the game in front of many eyeballs. These free bonus codes help the game developer to spread their creation, while gamblers can enjoy some free spins on fun online slot games.

And what’s more, there are many casino bonus codes for existing players, too. Many online casinos offer bonus codes as a part of a special birthday bonus or during special events. Bonus codes are simple and versatile - that’s their main appeal.

Disadvantages of Bonus Codes

While casino bonus codes may be fun, every online casino bonus offer comes with its caveats. One of the biggest disadvantages of bonus codes is the need for a deposit. In almost every casino that has ever issued bonus codes, it’s not possible to find no deposit bonus codes. Most of the time, bonus codes can only be redeemed for a deposit, even if the required minimum deposit is small.

Another significant downside involves wagering requirements and restrictions. Clearly, no bonus code comes completely free. There are always some restrictions involved on how the bonus code winnings can be redeemed, how much money can be won or which games are applicable when there’s an active bonus code on the player’s account. All casinos have some rules in place for using bonus codes and gamblers should always familiarize themselves with conditions to ensure they won’t miss out on anything.

Types of Bonus Codes

How to Convert the Bonus into Real Money

After using a bonus code at online casinos, the bonus will most likely end up on the ‘bonus’ balance, not the real money balance. This means the bonus money can’t be withdrawn unless it gets converted into a real money balance. Usually, there aren’t any clear-cut real money online casino bonus codes - the most standard promo code will require converting the money into real cash.

This is where wagering requirements come into play. The bonus money can be converted into real money funds by fulfilling the wagering requirement (otherwise known as the playthrough requirement). This condition requires the player to place some wagers before withdrawing the money - or, in other words, the player can’t just unlock some cash with a bonus code and then go on their merry way.

Wagering requirements may range anywhere from 1 to 50x (or higher) and the number marks the multiplier by which the received bonus must be played through. For example, a 100-dollar bonus with a 20x wagering requirement means the player must place bets amounting to 2000 dollars, after which the bonus money is unlocked and available for withdrawals.

Other Common Terms and Conditions

Whenever players redeem online casino bonuses and promotions, they’ll need to follow many terms and conditions besides the wagering requirement itself. Here are some of the common conditions players may face:

  • Minimum deposit - Deposit bonus codes require a minimum deposit for unlocking. If players don’t hit the minimum deposit limit, they won’t get the bonus related to the promo code.
  • Maximum bet - All bonuses have a maximum bet limit that applies to the gameplay as long as there’s an active bonus. Usually, players can’t place bets over 5 dollars or so, and if players cross that line, their account may get banned.
  • Maximum win - Though the best deposit bonus codes won’t come with maximum win limits, some may. If there’s a cap applied on the maximum win, it means the player won’t be able to redeem more than designated with the limit.
  • Excluded games - Not all online casino games are applicable to the same bonus code. Some promo codes are only meant for slot games, some are for live dealer games. Even more, sometimes bonus code winnings can’t be played through on all games - some slot machines may be excluded from fulfilling the condition.
  • One bonus at a time - As a general rule, two bonuses can’t be activated simultaneously. This means players have to plan their bonuses smartly and consider which bonus they want to activate first.
  • IP limitations - One bonus code can be redeemed from one IP. If the casino detects that the same IP has tried using the bonus code several times on different accounts, these accounts may get banned.
