What Is The “Catch” Of 400 UK Casino Bonus Offers?
The “catch” of all 400 casino bonus UK offers is the wagering requirement. This means all of your winnings are really yours to keep but you need to “unlock” them first. And to unlock them, you must wager a certain amount of money. Wagering means placing a wager on a game. Basically, you must deposit money and use it to play games until you complete the wagering requirement– this is how you unlock the slots bonus UK.
So, how much money you need to wager for this requirement? This is defined by the wagering rate. All casinos have a different rate, as can be seen above. This rate will show the total wagering amount needed to unlock the bonus. After unlocking it, you can withdraw your winnings (or use them to play games). Here is a table that shows different wagering rates for a 400% slots bonus to give you an idea:

Things You Should Know About Casino 400 Bonus UK Offers
- Make sure that there is no cashout limit or it is high enough. This means you are allowed to withdraw only a certain amount, no matter how much you have won. For example, if the maximum cashout limit is 250 GBP and your bonus is 1.000 GBP, you won’t be able to withdraw more than 250 GBP. The rest of your bonus will be void.
- Make sure the maximum wager limit is high enough. Until the wagering requirement is complete, you will have a maximum wager limit – usually 5 GBP. It should not be lower than this amount. Otherwise, it will take too long to complete the requirement.
- Make sure the wagering rate is low enough. Ideally, the wagering rate should not be higher than 40x, and it should be as low as possible. If this rate is higher than 40, it may be impossible to complete the wagering.
