3 key things you need to know about wagering requirements 

  • The lower the wagering requiremen, the better it is

  • They may require you to invest your own cash to get your bonus 

  • They apply to both spins and cash rewards 

Do returning players get casino bonuses?

While some people may think that the rewards stop once you’ve signed up, most online casinos offer ongoing promotions and a loyalty scheme for returning players. 

The bonuses you get will depend entirely on the site you’re gambling at, but some of the ongoing promotions may include: 

  • Daily free spins 

  • Favourable sports betting odds

  • Regular cash boosts 

The loyalty scheme benefits you get from casinos might feature the following things: 

  • Special prize draws 

  • VIP bonuses 

  • Cash rewards 

What are no deposit bonuses?

No deposit bonuses are a reward used by casinos to attract gamblers. They work by offering players either free spins or a cash bonus without asking them to deposit any of their own money. 

While this may seem like free money, it’s very important to know that no deposit bonuses may actually require you to indirectly deposit your own money to get them.

The reason for this is that you may need to build up game credit to get them and to get said credit you will need to place bets. This means two things: 

  1. You'll need to deposit some of your own cash to get credit in the first instance

  2. If you don’t go on a winning streak that gives you the necessary game credit for the no deposit bonus, you’ll need to cover any losses by investing your own money

So while you’re not asked to deposit your money to get these rewards, the reality is that you will need to spend some cash if you want them. 

What are free spins?

Free spins are a bonus that casinos use to encourage gamblers to bet on their slot games. 

These rewards can come as a sign up bonus for new players, or as an ad-hoc/ongoing promotion for loyal gamblers. 

One thing to keep in mind with free spins is that they’ll come with wagering requirements. 

This means you’ll need to wager a certain amount of your own money before you can get the full benefits of the free spins offer. 

What’s a cash welcome bonus 

Cash welcome bonuses are offers that casinos use to attract new gamblers. 

They generally work by offering to match an amount of money that you deposit to a certain percentage. 

For example, a welcome bonus may be a first deposit match of 100% for up to £100. In this case, if you deposit £100 then the casino will match it completely, giving you a welcome bonus of £100.

Something you need to know about welcome bonuses is that you may be required to make multiple deposits to get the full amount. 

For instance, the welcome bonus could be £1,000 split out in these ways: 

  • 100% first deposit match up to £250 

  • 100% second deposit match up to £250 

  • 50% third deposit match up to £2,000

What are wagering requirements?

Wagering requirements are one of the most important things that you need to know about casino bonuses. 

Why? Because they represnt the amount of your own cash you need to invest to get your bonus. 

Wagering requirements are used for both cash and spins offers and they’re shown as being “x” the amount of the value of the advertised offer. 

Using the example of a £100 cash welcome bonus, this is how wagering requirements work: 

  • 10x: 10x £100 – wagering requirement means you need to invest £1,000

  • 20x: 20x £100 – wagering requirement means you need to invest £2,000

  • 30x: 30x £100 – wagering requirement means you need to invest £3,000
