When you decide to join a new online casino, you will immediately be bombarded with massive, flashing advertisements for welcome bonuses.

However, the biggest number in bold print is rarely the most important detail when evaluating these promotional offers.

Why You Can't Just Withdraw the Bonus

Wagering requirements dictate exactly how many times you must bet the bonus amount before it converts into withdrawable cash.

Many rogue casinos offer absurdly large bonuses knowing that the player will mathematically lose everything trying to clear the rollover.

• A standard, fair wagering requirement in the modern casino industry is usually between 30x and 40x the bonus amount
• Anything above a 50x rollover should generally be avoided, as the mathematical odds of clearing it are incredibly low
• Some extremely generous casinos occasionally offer 'No Wagering' bonuses, where all winnings are instantly kept as cash

Types of Welcome Bonuses

A '100% Match up to $500' means if you deposit $500, the casino gives you another $500 in bonus funds.

Keep in mind that the winnings generated from these free spins will almost always be subject to their own wagering requirements.

The golden rule of casino bonuses is simple: if an offer looks too good to be true, the terms and conditions are probably terrible.
