How do real money casino bonuses work?
The vast majority of online casinos offer what is known as a match bonus, which grants you a certain number of free credits based upon the amount of your deposit. These promotions come in all shapes and sizes, and may work over just your first, or several deposits. Some work for all casino games, some bonuses are only available for certain games, like the pokies.
Many gambling sites nowadays also run a no deposit bonus, also known as a free sign-up bonus. This allows you to play real cash casino games without having to put any money down whatsoever. These are usually smaller amounts — $5 or $10 is common — and may come in the form of either cash credits, bonus bets, or free spins on selected pokies games. If you’re ever on the fence about a particular site or just want to test their games and their interface first before putting down real money, these types of bonuses are great to redeem as they give you a good idea of the real money experience which awaits you.
Secure cash deposit methods
You can’t claim a real money bonus without having a safe, secure way to add funds to your online casino account. Our trusted gambling websites support several such options — all of which are supported by multiple currencies, and which are protected by certified SSL (Secure Socket Layer) digital encryptions.
Credit and debit cards – Visa, MasterCard and most major credit cards are accepted at every casino, as well as debit cards like Maestro and Visa Electron. These are highly recommended due to the proven safety, security and reputation of each brand and the fact they are used worldwide for not just online gaming, but Internet shopping purchases, bill payments and more.
Web wallets – Neteller, EcoPays, ClickandBuy and Skrill are the most popular e-wallet solutions for casino banking.
Instant banking – A convenient option which allows you to make instant online payments from your personal bank account. Citadel Instant Banking is also widely available.
Prepaid cash vouchers – PaySafeCard codes can be purchased at land-based retailers all over the country, including newsagencies, service stations and telecommunications stores.
Standard banking methods – Direct bank transfers, wire transactions and cheques may be used at most casino sites.
Tips for playing with bonus cash at Internet casinos
Always read the terms and conditions first. Every matched bonus comes with wagering restrictions which require you to “play through” your bonus bucks a certain number of times before you can cash out your winnings. For example: if you take a $50 bonus with 10x wagering requirements, you might be asked to make a minimum $500 in casino bets before you can withdraw any funds. Know what you’re getting into before you accept any bonus.
ALSO READ: HOW TO GET FREE CASH
Make sure to activate the bonus when you deposit. Sometimes the option will be selected by default when you go to put funds in your online gambling account, and sometimes it will not. Always check that the right boxes are ticked before you confirm the transaction. The same principle applies when you don’t want any free cash added on, but in reverse: make sure there are no promos or bonuses selected when you complete a deposit.
Play within your means. Never feel obliged to take a bonus offer just because it’s there. Some of these deals, particularly on the third and fourth deposits, are aimed at VIPs — the high-stakes casino players with money to burn. If you have a limited bankroll to work with, there is no point claiming thousands of dollars in bonus money which you probably won’t clear to cash-out stage in the next 20 years. Set realistic targets and always gamble responsibly. Most players who have had the biggest online casino wins were those who had self-restraint.
