What a trial takes out of a game, and what it carefully leaves in

A game offered in "free play" keeps almost every component that makes a casino game work, and it loses the only one that teaches anybody anything. Every reel spins at the speed it always did, the paytable promises the same combinations, the "near miss" lands with the same sound (the same two bells, the same half-second pause), and the counter at the top of the screen rises and falls just as it would with money behind it.

What has been taken out is the stake, and the lesson leaves with it. An evening on virtual "credits" will show a player how a machine behaves, how its "bonus round" is paced (the multipliers, the pick screens, the retriggers) and where the buttons sit, and it will say nothing at all about what the same machine does to money that belongs to him.

The asymmetry runs one way only (nothing is lost, so nothing is learned), which is why we think "demo mode" deserves a warning rather than a shrug. A session on "play money" that goes badly costs nothing and is forgotten by the morning; a session that goes well leaves a memory of winning, and that memory is the one a player carries across to the version where the figures are real.

Where the law insists that the free game be the same game

Two European legislators have decided the risk is real enough to write a rule against, and both chose the same remedy rather than a ban on what the trade calls a "demo" (identity, not prohibition). Swedish law forbids a licence holder to provide "free games, test games and similar games" whose random outcome differs from the corresponding game played with stakes (the Spellagen, chapter 14 section 5, in its 2025 wording).

The German treaty of 2021 goes further still, and it goes further precisely on the arithmetic. A free entertainment offer that reproduces a licensed game has to correspond to it "in particular as regards the probability of winning and the payout ratio", and where the real game carries fees or similar charges, those charges must be simulated in the free version and stated openly (§ 6j of the treaty, in force since 2023).

Neither rule exists for the fun of it. A "fun mode" tuned to pay more generously than the product it advertises is not a trial but a sales device, and the two parliaments that wrote those provisions were plainly looking straight at that practice when they drafted them.

Identical mathematics still does not produce an identical experience; one platform admits as much in its own guide to slots: "practice play" may limit certain features of a game, and no real money can be won in that mode at all. A reader should treat a trial as a sample of the software (the rules, the pace, the interface) and never as a forecast of an evening.

The three things a trial cannot show, however honest it is

The first of the three is variance, and it is the one that empties an account. A "payout ratio" (the figure a lobby prints as "RTP") is a long-run average computed over a number of rounds far larger than anybody plays in a night, and the distance between that average and a single session is where every real loss happens; a twenty-minute trial says nothing whatever about that distance.

The second is the cost of chasing, which is the most expensive habit in this trade and the one a free game is structurally unable to rehearse. The impulse to win back what has gone cannot appear while nothing has gone (the loss has to exist before anybody can chase it), so the behaviour that does the damage is exactly the behaviour a trial leaves untested (and therefore unlearned).

The third is money itself, in the dull administrative sense. A trial never asks anybody to look at a bank balance, to decide in advance what an evening is worth, or to feel the gap between a "deposit limit" set in a calm hour and the same limit at midnight!

What actually works, and where to find it

A limit set before play is worth more than any quantity of resolve during it (the calm hour decides better than the late one), and every licensed operator is obliged to offer one. Set the deposit limit when the account is opened, write down what an evening is supposed to cost, and treat the arrival of that figure as the end of the session rather than as a prompt to add funds.

"Self-exclusion" is the stronger tool, and in a good many markets it is national rather than site by site (one form, one market, every licensed site at once). A single registration closes every licensed operator in the market at once, and that is the feature which makes it work: the decision is taken once, in a clear hour, and it does not have to be taken again at every site a reader stumbles into.

The limitation is worth knowing before anybody relies on it. A national register binds the operators licensed in that country and nobody else, so a site holding no licence there sits outside the scheme altogether, and the brands on our own list are of exactly that kind for most of the countries our readers write to us from. That is worth saying twice, because a national scheme is often described as though it reached every site a reader can possibly find!

Age is the other hard line, and it is not drawn in the same place everywhere. Eighteen is the threshold in most of the markets described on these pages, nineteen applies in Ontario, and twenty-one applies in Belgium and in the United States (two markets, one province, three different lines), which is why the "18+" line printed on a page here changes with the market that page was written for.

The services, market by market

The list below carries the national self-exclusion scheme and the public help line of each market covered by this site, taken from the authority or the service itself and not from a directory, because we would rather send a reader to the body that runs the scheme. Where the register and the help line are operated by different bodies, we name both (the register first, the telephone number second). None of these organisations has any connection with us, none of them pays us anything, and none of the links on this page is commercial.

Every service in that list answers people who are not certain they have a problem at all, which happens to be the commonest reason for not calling one of them. The registers are administrative and quick (a form, a confirmation, a period that cannot be shortened), the help lines are confidential, and not one of them asks a caller to have reached a crisis first.

When a trial has stopped being a trial

A few signs tell a reader that a free game has turned into something else, and they are all easier to notice in somebody else than in oneself: the session meant to last twenty minutes that lasted three hours (and then four), the hunt for a version with real stakes because a virtual balance has stopped counting, the quiet arithmetic about what the same spins would have paid; the word for that last one is "chasing", and it has a name because it is common.

Any one of those is a good moment to stop reading pages like this one and to use the register for your own market instead. "Responsible gambling" is a dull phrase for a simple arrangement: gambling is entertainment and never income, a trial is a demonstration and never a forecast, and the only figure on any of our pages that you control completely is the one you decide not to deposit.
