18+ only (21+ in most US states). Some links are affiliate links and this site earns a commission when an account is opened through one — at no cost to you, and with no effect on any figure. Gambling is legal in some jurisdictions and an offence in others, and it is your responsibility to know which applies to you. Gambling is entertainment, not income: the arithmetic on this site exists so you can see what it costs. If it has stopped being a choice, help is free and confidential: the National Gambling Helpline on 0808 8020 133 in the UK, 1-800-GAMBLER in the US.

We do the arithmetic before we make the recommendation.

Every game has a number. So does every bonus.

A roulette wheel keeps 2.7% of everything staked on it. A slot might keep 12%. A £100 bonus at 35× wagering is worth about £18 if you clear it on slots and less than nothing if you do not. These are arithmetic, they decide what an evening costs, and almost no site that recommends casinos will show you the working. This one does.

Almost every site that ranks casinos is paid when you sign up at one, and almost none of them say how the ranking was produced. This site is paid the same way — that is disclosed on every page carrying a link — and the difference is that it publishes no ranking at all. It shows the arithmetic and the checks instead: the return to player, the parts that make up a withdrawal time, the wagering multiple, and the clause in the terms that voids a win.

What is on the page

The house edge of each game and what it costs per hour at a given stake and speed. The real value of an offer once its wagering requirement, its game weighting and its maximum-conversion clause are applied. What decides a withdrawal time, how to read each part of it from an operator's own terms, and how to check a licence on the regulator's public register. Where a figure depends on a rule that varies — deck count, single or double zero, which games clear a bonus at what weight — the page states the rule it used.

How this site is paid

Some links to operators are affiliate links, and this site earns a commission if you open an account through one. It costs you nothing and it changes no price. It also changes no figure: every number on this site is derived from game rules or offer terms, and none of them describes a named operator, because nobody behind the site holds an account anywhere.

What is not here

No invented ratings out of ten, no “exclusive” bonuses that are the public offer with a tracking code, and no claim that a game is due, hot, or beatable by a staking pattern. Progression systems change the shape of the distribution, not its mean, and a page implying otherwise is wrong in the direction that costs the reader money.
