Example: 100% up to ?300. As it’s 100%, this means that the casino is only willing to match what you deposit. However, they give you the opportunity to land a lot more extra money in total if you wish. Here are some examples:

  • Deposit ?300 = ?600 overall (?300d + ?300b)
  • Deposit ?500 = ?800 overall (?500d + maximum extra of ?300)

What is a welcome bonus?

A welcome bonus is a reward that a casino offers to new players for signing up. The exact reward depends on the offer, but it’s usually either extra bonus money or free spins. At all of the casino sites we recommend, you will be offered a welcome bonus.

Welcome bonuses can be extremely lucrative, as it’s the casino’s chance to tempt you to play at their site so they will often try to offer something particularly generous or different. You can activate a welcome bonus in the following way:

  1. Go to your chosen casino
  2. Create a new account
  3. Make a deposit
  4. Receive the welcome bonus

Some casinos need you to choose a welcome offer manually. For example, you may need to select it from a drop-down list or input a promo code when making a payment. These things completely depend on each site but they should be clearly signposted so that you don’t miss out. If you’re ever in doubt then you can contact the casino’s support team who will walk you through it.

How do casino welcome bonuses work?

You need to keep in mind that the small print often defines what the best online casino welcome bonus is or isn’t.

Most casino welcome bonuses work by giving you more money to play with on top of what you deposit. Exactly how much extra money you get depends on three things – how much you deposit, how much the casino is willing to match your deposit, and what the maximum bonus best casino sign up bonuses amount is. It might sound complicated at first but bear with us and it’ll soon be simple.

Example: a very common welcome offer is 100% up to ?100. The 100% part means that the casino is willing to match your payment in full – so if you gave ?50 then the casino would give you ?50 extra money. However, there is a limit.

The ?100 part tells you the maximum amount of extra money the casino is willing to give. So if you were to deposit ?150 then they would only give ?100 extra.

All that extra money you’re given? Unfortunately, the casinos don’t just let you take that out. Instead, you need to wager it.

Pretty much all casino welcome bonuses will have what’s called wagering requirements attached. This means you need to use your bonus to bet over and over until you’ve reached a certain number. Wagering will be stated as something like “x20”. This means you’ll often need to multiply what you get as extra money by 20 to know how much you need to bet. Again, it sounds complicated but it’s best explained in an example.
