Online Casino Bonuses Explained



Match Rate & Max Bonus Amount
Match rate is the percentage of the bonus offered by the casino. An online or mobile casino might offer a 100% match on your first deposit, which is the match rate. Max bonus amount decides how much bonus money you can get. IF it is capped at $500, that means you can place a $500 first deposit and get a $500 bonus match. If you deposit $1000, you will still get the capped amount at $500.
Bonus Codes
Some casinos will allow you to get bonuses without a promo code. But some bonuses will have a promo code. Without providing this promo code while signing up, you will not be able to access the bonus.
Wagering Requirements
Wagering requirements determine how much money you must spend before your bonus + winning money converts into real money. If a casino has 20x wagering requirements on a $10 bonus, then you should spend $10 x 20 = $200 before your bonus money turns into cash that you are allowed to withdraw. This is why you should choose a casino with Low Wagering Bonuses.
The terms and conditions of a bonus are important, and you should never sign up for a casino without this. Why? The terms and conditions of the bonus will contain the bonus code, if any, without which you cannot access the bonus. Knowing the wagering requirements always helps. Some casinos will have an extremely high level of wagering bonuses. Casino bonus 20 is one of the more reasonable ones.

Can You Cash Out The Bonus Money?

As tempting as it would be to simply cash out the bonus money gifted by the casino, casinos expect this to happen. This is why they have implemented the wagering requirements. Until you fulfill the wagering requirements, you are not allowed to withdraw the money from your account. In summary, it is not real cash until the wagering is fulfilled.


It’s simple. Casino Reload Bonus, welcome bonus, casino registratiom bonus, and free spins are some amazing bonuses offered by casinos. They implement wagering requirements, which makes people spend a certain amount of money before they can withdraw their free bonus money. Some people will multiply their winnings, but most people will not.
A minimum deposit casino has a money deposit limit. You must deposit at least $5, or $10, or whatever the deposit amount is, to get started. The casino will not allow a lower deposit amount.
Your details separate you from other people. Millions of players play in the casinos, and most of the players will try to cheat the casino by creating multiple accounts to claim the bonus twice. After casinos have been through some issues with players abusing the bonus policy, proving one’s identity became mandatory in the casino.
The casino will tell you the eligible payment methods in the terms and conditions. Read through to see if it is a Neteller casino bonus, or eligible for any other specific methods.
