每个在线赌场都会这样告诉你，只要你注册，他们就会给你很多很多钱。记住你父亲曾经告诉过你：天下没有免费的午餐。首先，有极少数网站提供的奖金是没有存款的。如果你发现一个网站提供一个没有存款奖金，请远离这样的网上赌场。

　　当涉及到存款奖金时，一定要仔细阅读相关条款并保持警惕性。首先，你需要充分了解网上赌场的所有存款规则要求，避免违法这些相关条例。需要特别小心，如果你不小心违反了一些相关规则，你可能面临被罚款的境遇。

　　不过，如果你是一个老虎机游戏玩家，网上赌场的免费奖金会给你额外的玩游戏的时间，甚至额外的中大奖的机会，这对许多老虎机游戏玩家来说，是一个非常甜蜜的诱惑。不过，即使如此，检查网上赌场奖金细则依然是必要的。很多网上赌场所提供的免费奖金，只是向你提供免费在线玩的机会。这意味着奖金失去了它的价值，因为你不能兑现。

　　但这并不意味着网上赌场提供的免费奖金是没有意义的。比方说，你在一个网上赌场存了100美元，得到200美元的奖金。你在游戏结束时赢得了500美元。当你去兑现时，他们只给你300美元，也就是说你净赢了200美元。

　　玩网上赌场游戏是值得考虑的，但重要的是要知道网上赌场奖的金跌宕起伏。

　　Every online casino tells you that they’ll give you lots and lots of money as soon as you sign up. Remember what your father told you: there’s no such thing as a free lunch. First, there are very few sites that offer bonuses without a deposit.

　　When it comes to deposit bonuses, be sure to read the terms carefully and warily. That will usually be twenty to forty times the value of the deposit plus the bonus. Be careful, though. If you play the wrong game, it could be two hundred to four hundred times the value, and if you play the wrong game on some sites, your bonus and all of your winnings can be taken away for violating the terms and conditions of the bonus. If you play blackjack, craps, baccarat, or roulette, you might be better off forgoing the bonus altogether or asking the customer support staff if there’s a special bonus for your game.

　　If you’re a slots player, though, the bonus will give you extra hours of play, and extra shots at the jackpot, so it’s a pretty sweet deal. Even then, though, check the terms and conditions. A lot of sites say that the bonus is only for play. That means that they remove the value of the bonus from your winnings when you go to cash out.

　　It’s not all bad though. Let’s say you deposit $100, get a $200 bonus, and at the end of your playthrough, you have $500. You go to cash out, they give you $300, which is a net win of $200.

　　It’s a lot to consider, but it’s important to be aware of the ups and downs of online casino bonuses.
