It appears great, wow you say, free cash? Offcourse. So you downloaded the casino and registered.. You play the bonus amount received and most often you loose as the bonus in form of free cash is so small it is impossible to win. Some do win though, few, but they have to deposit money to get the bonus - not too bad though but still such rules are not known by fresh gamblers as it is written in small text on their terms and conditions.
Casinos before, some of them, had no maximum cashout with such free bonuses. Today though 90% of them have maximum cashout limi ts meaning even if you won an amount of $3000 or more you will not be able to withdraw more than $50 - $300 - So whats the point?
Many casinos as well require you to fill out forms, send papers of visa card and different other documents, this is time consuming and of what I believe all these factors mentioned above are neither positive for the casino player neither for the casino industry.
If you dont have money then wait to play by saving some each day - In this way at least you will have a chance of winning.
