Every online casino will offer new players a casino bonus as a one off introduction to the casino and this is usually given in the form of a deposit match bonus which means effectively that the online casino will make funds available in your account that is a percentage of whatever your first deposit is into the account. This online casino deposit matching bonus is generally 100% of your deposit but it can sometimes be applied to your second or even third deposit as well in which case it is often only 50% or less. The point to remember however is that online casinos are not giving money away that you can immediately withdraw as they point out that it is to enable you to play longer. If you are fortunate enough to win when using the casino bonus funds you will have to comply with their terms and conditions before you make any withdrawals and these are normally explained in terms of “play through” requirements which means the number of times your online casino bonus must be staked before you can take money out of the account. Always read the terms and conditions carefully to avoid disappointment as sometimes this play through requirement refers to the casino bonus amount only but sometimes it applies to the casino bonus amount plus your original stake. Another point to watch for is which casino games are applicable to the play through as generally some casino games such as roulette or blackjack are either not counted at all or are counted for a much lower percentage as thjey are considered low risk casino games. Stakes on casino slots will always be counted for 100% towards the requirement. The purpose of these online casino bonuses is to allow you to play longer and have more enjoyment.
