Recently I have been thinking about this ''strategy'' that is free but difficult to pull off. Essentially you would go from casino to casino, getting all the bonuses and welcome bonuses they give and trying to rollover them to eventually withdraw the money won. This ''strategy'' is obviously risk free since you are not using your money, the clear downside is the rollover part, 100% of the bonuses they give will need to be wagered 20 times, 40 times, 100 times, whatever it is, it's always a huge number so you clearly need a lot of luck but hey, you are gambling, you need luck anyhow, right? I think we could make a list of the best casinos that offer the best bonuses here, any ideas?

Sites didnt made this just to give away money but they also have it seen in the future. You cannot gambling in just depending on the bonuses you collected because sites knows it can happen and they can possibly have a system which has greater odds if you put your bonus money.
