Casinos might choose to give you a free spin or bonus based on your commitment and how frequently you gamble in their casino. However, your tier also depends on how often, you will get bonuses from the casino.
Some casinos, when you are in the VIP tier, at the end of the week, they give you back some percentage from your losses, so that you can gamble and wouldn't feel your losses that much.
Yes, you made an important comment. Nowadays, many online casinos offer their customers various bonuses or incentives based on their regular play, such as free spins, cashback or VIP rewards. While these offers may seem attractive, it is important to remember that casinos are in business, and ultimately they want to make a profit. Therefore, it is wise to understand the hidden terms and conditions behind any bonus or reward. Playing for fun is fine, but playing responsibly is most important. Thank you for your comment.
