A 550% package you cannot finish is worth less than a 110% one you can. The headline percentage is marketing; how the package is split across deposits, and how long you get to use each part, decide what an offer is really worth.

The top 7, ranked

Welcome offers ranked by what they are actually worth, not by the headline number on the banner.

How this list was built

The same four checks are applied to every casino before it appears here.

  1. 1

    How the package is split

    Almost every headline here is a total across several deposits. We break it down tier by tier so you can see what reaching the advertised figure actually costs.

  2. 2

    Max bet while a bonus is live

    Usually £5 a spin. Breaching it can void the offer and any winnings from it, and it is enforced automatically.

  3. 3

    Game weighting

    Slots normally count in full, live tables far less or not at all. A table-game player gets much less from a slots-only offer.

  4. 4

    Win caps and expiry

    Some offers cap what can be withdrawn from bonus winnings. We list the cap and the expiry window for each.

Questions about this list

How do I work out what a bonus is really worth?

Look past the headline percentage to how the package is split, what each deposit tier requires, and how long you get to use it. A large total spread over four deposits with a short window is worth less than a smaller offer you can actually finish.

What is the most common way people lose a bonus?

Exceeding the max bet while bonus funds are active. It is typically £5 a spin, it is enforced automatically, and it voids everything: the bonus and anything won with it.

Are no-deposit bonuses worth claiming?

As a free look at a casino, yes. As a way to win money, rarely, because what you can withdraw from them is capped, often at £50 to £100.

Can I withdraw bonus credit straight away?

No. Cancelling a bonus before it is cleared normally removes the bonus funds and anything won from them, leaving your original deposit balance.
