Casino Bonus Codes

A casino bonus code is a string of letters or numbers (or a combination) you have to enter when making a deposit or register for an account if you want to be eligible for the bonus offer. You can find working deposit bonus codes from our website, promotional emails and advertisements on the casino’s website.

In 2021, a deposit bonus code is rare in online gambling. Nowadays, it’s more of an exception than a rule that you need to use a promo code.

How to Use Online Casino Bonus Code

Here’s our step by step guide on how to claim a casino depositbonus using promo codes:

  • Choose your favourite bonus and click a link from BonusFinder.
  • Sign up with the registration form.
  • If there is a code you need to use, it automatically fills in on the registration form. After that, you’re eligible to receive your sign-up bonus.
  • Fill in the working code if it doesn’t fill in automatically.
  • Finish the registration process and start playing.

In case the code you added doesn’t work, you can directly contact your online casino’s customer support, and they will happily help you get your bonus money.

Different Types of Casino Bonuses

Casinos offer several types of bonuses, including the sign-up bonus, free spins, bonus spins and welcome package offers. To make it clear what you get from casino bonuses, BonusFinder explains the different bonus types. Below you can find the different types of casino bonuses explained:

  • Deposit Bonus
    First deposit bonuses are the biggest and most common casino promotion, forming the basis of almost all welcome packages. They are also given to existing players, but then they are called reload bonuses. The deposit offers are tied to how much you deposit, calculated from the match-up percentage (match bonus) and limited by the maximum bonus amount.
  • No-Deposit Bonus
    Online casino players always get brilliant no-deposit bonus offers. You get free spins and bonus money to play games from different casino game providers. Microgaming is a must-have for jackpots fanatics, Evolution Gaming rules the live casino, and NetEnt has some of the hottest and most played games around.
  • Extra Spins
    Extra spins, often erroneously called free spins, are real-money spins you get when you deposit and are for selected games, typically online slots games, and they have the least terms and conditions attached to them. Another great thing about these spins is that you often get them with a match-up bonus. Free spins no deposit offers are especially great when playing jackpot games with them – win big without putting your money in!
  • Existing Players: Loyalty Bonuses & VIP Bonus
    Existing casino players also get various extra rewards as loyalty bonuses and via a VIP scheme. Most online casinos have a rewards program that allows you to collect bonus points. If you stay loyal to a casino, you can get VIP treatment. Bonuses from a VIP program are mostly extra free spins, cash prizes, deposit bonuses or a chance to exchange your VIP points for cash.
  • Deposit lotteries
    Besides spins and extra money, casinos often run different deposit lotteries. Typically they work so that your deposit is a ticket for a draw, where you can win something fun. As deposit lotteries are standard at online casinos, the prize is almost always the latest iPhone when a new iPhone model comes out.
  • Cashback
    A cashback reward program is an incentive program operated by online casinos where a percentage of the amount spent is paid back to your casino account.
  • High roller bonuses
    High rollers are players with big gambling budgets and players who are looking to gamble with high stakes. We have a couple of exclusive casino bonus offers for big money games.

Terms & Conditions Explained

Before you claim an online casino welcome bonus, it must be that you read the T&Cs attached to the bonus offer. In 2021, online casinos are always required to make their T&C very visible and easy to read. They are usually quite similar, but some differences make some bonuses worth it more than others.

We explain the most common terms & conditions casinos attach to their free spins, deposit bonus money and other bonuses. Every offer we have on the site can be used on a mobile casino. Most often, bonuses exclude live casino games. While the rules don’t make it impossible to win, they limit what you can and can’t do while playing with your bonus.

Wagering requirements

The most common limitation attached to casino bonus offers (especially on a welcome bonus) is a wagering requirement. It dictates how many times you must wager your welcome bonus before you can withdraw them. Both the winning and losing rounds count towards wager requirements.

Until you have cleared your playthrough requirements, your wins are locked in a bonus balance. Most online casinos have a wagering requirements of 30 to 50, but then there are low wagering casino bonuses with requirements less than 20x and no wagering casinos with 0x.

Maximum win

Always check the welcome bonus terms and conditions. A few irish casinos limit the amount of money you can win when you play with casino bonuses. As annoying as this sounds, it’s a way to protect themselves, and it’s enforced chiefly on no-deposit bonuses.

Minimum deposit

Often, casinos attach a minimum deposit amount to every deposit bonus type they offer. You can get excellent match deposit bonus offers with a minimum deposit of 10€, 20€, 50€. These welcome bonus deals could be even more valuable to you than some free spins no deposit casino promos!

Payment Method Restrictions

You might not be eligible for the deposit bonuses with specific payment methods (usual e-wallets such as Skrill and Neteller) at real money casinos. Always make sure you can receive the deposit bonus before you make a transaction.

Game Restrictions

Usually, there is a prechosen list of slot games you can play with free spins and sometimes also deposit bonuses. Moreover, not all games contribute to wagering requirements and not all casino games contribute equally to the wagering requirement.

Most table games and video poker are often off-limits; some casinos limit progressive jackpot slots as well. The game selection options you have are primarily due to the high return to player (RTP) of these casino games.


Make sure your welcome bonus offers won’t expire. Most casinos require you to meet the wagering requirements in a specific time frame before you can cash in your welcome bonus. Casino bonuses are usually only available during your first week after registration, while for other bonus types, it is usually 30 days.

Betting Limit

When you play with bonus money, you should keep an eye on your T&Cs. All casinos limit how much you can bet with your welcome bonus funds. When playing with cash rewards, the maximum bet size is tied to your deposit or bonus value most of the time.

For example, the max bonus bet could be 10% of your deposit. Sometimes it’s a limitation on how much you can bet per spin (5€). If you wager more, you’ll be in breach of terms & conditions and can’t cash out your winnings.
