There are different kinds of person in the world, there are those that will prefer to play nust for fun, and those that are really in to gambling because they aim for profits but if I were to evaluate these two, I think those that play because of profits are quite more frustrated unlike people who play just for fun. For me, I always play not because I want some profit, I play because I try to consume free slots and game offered by various gambling sites, just for the intention of fun.
you are not adding own money when the freebies are gone?it means you can control yourself from betting more aside from the free rolls from each sites?good for you if that is true because you are preventing yourself from losing own moneyh,or either you just have no other amount to spend?but if giving a chance to play more will be indeed?
but for me?just keep in up and never change that attitude for you to have more fujn and not more losing.
