Betting Sign Up Offers and Betting Bonus Offers – FAQs

At Free Bet Castle, we are dedicated to being as transparent as possible about the free bet sign up and betting bonus offers that are available from the bookies above. If you’re interested in more details about how the betting sign up bonus works, then we’ve answered some frequently asked questions below although you should use the information below as a guide as each bookies betting bonus is slightly different:

Can I receive a sign up offer?

Yes, you can receive a free sign up bet and take advantage of the online betting promotions provided you are over 18 years of age and that you have never opened an account with that online bookmaker. There are some other exceptions that may apply as well e.g. employees of the bookie are ineligible for instance.

What can I use my free bet on?

It depends on the free bet offer that you chose to claim or the bookmaker that you have chosen to place your bets at. Generally, bookies allow you to place free bets on any of the sports betting markets that they offer bookmaker odds on although some of the bookmakers require certain odds to qualify for your sign up offer. Additionally, it’s important to note that within some bookies terms and conditions that you need to use your free bet within a certain number of days when you join.

Where do I get my free bet?

Bookies vary in how they award their free bets although, generally they credit your betting account with a free bet after you have signed up and placed your first real money bet. Some online bookies give you a free bet once you have registered although, the majority of them give you your free bet once you have deposited and placed your first bet.

Are all bets valid for the sign up betting promotions?

To claim your sign up bonus, some online bookies require your first bet and free bet to meet certain criteria such as minimum odds on a particular betting type or selection. Each individual bookmaker structures their offer slightly different which is why we have created dedicated landing pages for each of the bookmaker sign up offers.

What other types of free bet promotions are available to new customers?

Some free sign up offers let you deposit a smaller amount than the free bet amount e.g. deposit £5 get £20 free offer that is available to you. Additionally, some bet promotions allow a number of free bets over a certain period of time providing that certain conditions are met.

How do I sign up for a bookie?

After you have selected your free bet offer, click through to the bookmaker’s website by using some of our “Click to Claim” buttons. Once you have done that, you will be taken to the betting site and you will need to enter some personal information and contact details so you can register for your online betting account.

After you have signed up for an account, you will need to deposit some money using a credit card, debit card, PayPal or another form of deposit methods. The majority of bookies generally require you to place your first bet with the money that you’ve deposited within your account before they will release your free bet. Once you have then met your free bet offer criteria, the bookie will then credit your account with a voucher or code that can be used in their betting markets.

Can I deposit less than the sign up offer amount?

Generally most free bet on sign up offers allow for a minimum free matched bet offer which is the same as the minimum deposit amount. However, that can restrict the amount that you will receive in your free bet offer.
