- Complete the Rollover Requirements: Almost any bonus has rollover/ wagering requirements, and before you can withdraw your bonus cash, you need to complete these. If a bonus has a 30x rollover and you receive a $100 bonus, you will need to place wagers worth $3,000 in total before withdrawing.

- Matched Deposit Bonuses: A casino will match your deposit by a certain percentage, often found like 100% casino bonus and 200% deposit match bonuses. For example, deposit $100, and you’ll get an extra $100 to play with. These bonuses typically come with wagering requirements that must be met before withdrawing.
- Free Spins: These are exclusive to slot games and let you spin the reels without spending your own money. Free spins are often part of a welcome package or tied to a specific game. Winnings from free spins may also have wagering requirements.
- No-Deposit Bonuses: No-deposit casino bonuses give players free credits or spins without requiring an initial deposit. These rewards aren’t as common as they used to be. However, some sites will still offer them in exchange for completing small tasks like registering, for example.
- High Roller Bonuses: For players making large deposits, high roller bonuses offer bigger rewards, often exceeding $5,000. These bonuses usually come with tailored terms and may include additional perks like VIP access.
Casino Bonuses for Existing Players
For regular players, casinos offer various ongoing promotions to keep the excitement alive. These bonuses reward loyalty and incentivize continued play. Below are some of the best online casino bonuses for existing players:
- Reload Bonuses: These types of bonuses can only be claimed if you’ve already made at least one deposit at the casino. They come in the form of bonus cash, cashback, and free spins and will often come with a minimum deposit limit and wagering requirements.
- Cashback Bonuses: Cashback casino bonuses give you a percentage of your losses back as bonus funds. If you lose $100 with a 10% cashback offer, you’ll receive $10 back. It’s a safety net that reduces financial risk.

Online Casino Bonuses Terms & Conditions
All online casino bonuses will include T&Cs that you’ll need to adhere to to claim your reward. It’s important to read the terms and conditions carefully before participating in one. To help you better understand the terms and conditions, we’ve compiled a list of the most common ones you’ll come across.
Do I Need Casino Bonus Codes?
The best casino promotions often require codes to claim them, but some operators don’t use them and let you select the bonus from the site or even apply some automatically.
Bonus codes can offer various rewards, including welcome bonuses, deposit bonuses, no-deposit bonuses, free spins, cash rewards, etc. However, players should know that some codes don’t offer direct bonuses but perks like access to tournaments, VIP programs, exclusive game access, etc.
Finding the bonus codes is an essential step towards taking advantage of various bonuses. You can grab current codes at casino websites on their promotions page or by signing up for their newsletter. Many casinos also have affiliate sites where they promote codes that aren’t directly available on casino sites.
Last but not least, If you are active on social media, it’s generally a good idea to connect with online casinos because they often promote codes that expire quickly. Here are some of the top casino bonus codes we’ve picked for you.

Players will earn points for bets placed, which can be exchanged for rewards. Many programs come with various levels. The higher you rise the ranks, the more generous the rewards become.

ReadWrite’s Tips to a Smart Use of Casino Bonuses
These are our top five tips to help you make a profit when using any online bonus:
- Find crypto deposit bonuses – Using cryptocurrencies to fund your account since these tend to give the highest-value rewards.

- Find low rollover requirements – When the wagering requirements are low, you have a better chance of getting the most bonus money.
- Play slots – These casino games normally contribute 100% to the wagering requirements, and they’re more likely to turn a profit than table games.
- Choose slots with a high RTP – You’re more likely to win in the long term with games that have high average payouts.
- Play for fun first – Before claiming a bonus, check out the terms and conditions to see which games will need to be played in order to meet the requirements. This way, you can try the game in demo mode to see if you’d enjoy playing it before using your bonus funds.
