Is a no purchase casino really that? Well some have hidden rules that you must purchase in order to withdraw the bonus. If you have intentions on purchasing then it is not a problem. But if you never had planned or are unable to purchase at online casinos, then you really wont be able to claim the winnings. This is pretty common at most online casinos, as in the past players abused these type bonuses which cost the casinos money. So they only want players that if they do enjoy the casino, can continue to play and purchase credits. While many online casinos do give away bonuses, they also have terms and conditions which should be reviewed before signing up as a real player. You may not accept the terms in which the online casinos have in place. Not to say that they are all bad, you will have to be the judge and decide if they are acceptable to you.
