What is the best casino offer for me & what is the difference between a free no deposit casino bonus compared to a matched deposit bonus? We have explanations for each of the casino offers provided by leading UK casino & gaming sites.

New Customer Welcome Offer

When you register with any online casino site as a new customer, you are normally eligible to claim a welcome bonus. Welcome bonuses are used as an incentive for newcomers and usually provide players with a boost in funds. Which simply means they have more cash to play real money casino games with. They do tend to vary from casino to another.

Some of the popular offerings are: Free no deposit bonuses, Free spins, but most casinos’ offer matched deposit bonuses.

Matched Deposit Offer

A matched deposit offer sort of speaks for its self. Generally, this means that when you register an account with an online casino & make your first deposit, the bookmaker will match that amount in free bets.

For example: If the said offer states that you’ll receive 100% up to £100 on your first deposit +25 free spins when depositing a minimum £10. This means that if you decide to deposit £50, the bookmaker will match that & provide you with 25 spins for free. So you then have £100 available to bet with.

No Deposit Casino Offer

What's great about a no deposit casino bonus, is that you get to test out the casino site & its games for free. Which essentially means it’s a risk-free bet, as you haven’t had to deposit any of your own money. Hence the term, free no deposit casino offer.

Online Casinos with Free No Deposit Spins

There are some UK casino’s that offer free no deposit free spins as a bonus for registering as a new customer. However, a lot of casinos’ now offer them as an added extra when making your first deposit. Changes were made to free spin deals due to the wagering requirements, as some players wanted free spins & to keep what they win.

This is why we always recommend that you check out the terms & conditions when claiming your free casino offers.

Summary

You have probably noticed that the mobile & online UK casino sites featured on our website are recognised as the industry leaders. We feel that when recommending casino offers & bonuses to anyone, it’s important that the casino brand has a solid reputation & are trustworthy.

Which is why our online casino experts here at Free Bookie Bets will continue to add to this list of free casino offers in the future.
