FREE BET BETTING GUIDE - How to use your free bets

Bookies often offer a free bet if you sign up as a new customer or as another regular promotion. All you need to do is to select one of the free bets above, create a new account and accept the offer. 

If you want a match-specific, event-specific or personal offer which you can't find one our FREE BET page, please contact our support. We arrange special deals for our VIP players.

Free Bets 

It is almost impossible to beat a casino, but if you use the casino bonuses smartly, it is possible....

Casino's are always winning, If you want to make some money with gambling or betting it's important to use the bonuses from the online casinos. With the bonuses or free bets you don't always have to pay to see a return on your investment. There is many competition between online casino's, so the top operators and others in the business often try to seduce you with free bets or bonuses. 

Sometimes you have to do something to receive a free bet, but the fact remains that you don't always have to spend your own money to gamble. There are many different kind of bonuses, like risk free bets, money back free bets, reload bonuses, welcome bonses, profit multipliers paid out in free bets. Sometimes the free bet has a wager requirement. 

Free Bets are non-refundable and can most of the time not be withdrawn from your Account. Once you have wagered a Free Bet, however, any winnings from your Free Bets will automatically transfer to your Main Balance from where you will be able to withdraw them as cash or wager them in non-Promotion play. Once you have wagered a Free Bet, any winnings from your Free Bets will automatically transfer to your Main Balance from where you will be able to withdraw them as cash or wager them in non-Promotion play.

Using the free bet smartly

You don't have to bet your own money if you can use a free bet, but that doesn't mean free bets are 100% restriction free. To prevent abuse and to ensure the bookies don't go bust, there are some rules you have to be aware of before you place the free bet. The first thing you have to keep in mind is that you first have to make a deposit or place a bet before you receive a free bet most of the times. 

Example: if you want to receive the William Hill Casino Free Bet with the link below you have to meet the requirements below:

  • New William Hill online customers only

  • Min. unit stake of £10/€10 at odds of 1,5 or greater

  • Only the “win” part from Each Way bets will count

  • Free bets credited as 3 x £10/€10

  • Free bet stakes are not returned as part of the settlement of successful free bets

  • All Free Bets must be wagered within 30 days.

  • Cash in my bet will be available for bets placed using a free bet (minus the value of the initial free bet)

So a free bet is only for new customers and your bets have to meet some requirements. But it's still pretty easy to collect the free bets. If you win some money with the free bet you can do whatever you want with the money you won.

New Customer Free Bets

The most popular and most of the times most lucrative offers out there are the new customer free bets. Every online casino has a standard welcome bonus for new players regardless of the time of the year. For example: MR Green gives always 2x €25 free bets for new players. Most of the times they offer better and higher free bets at special occasions, like the Football World Cup or at Boxing Day. Don't forget to check the Free Bets pages whenever a major sporting event is approaching. This is the time when many online bookies will offer better en bigger deals. 

Free Bets for Existing Customers 

After you have received the welcome bonus in form of free bets, free cash, cashback bonus or enhanced odds they don't stop. Online Casinos often have a loyalty program for loyal customers, so they can benefit from other kind of bonuses.

Event Specific Bonuses for Loyal Customers:

Online casinos will give their loyal players all kind of bonuses, but most of the time they are not as good as the first deposit bonus. Most of the time loyal players will receive risk-free bets, refunds, enhanced odds and special promotions at major sporting events.
