What the casino records about your play

You hand a plastic card to the dealer before your first bet. By the end of the night, what does the casino know that it did not know before?

Those same three numbers make both answers. What the hour costs you can be worked out to the cent, because the pace of the game and the share of each bet the game keeps are both figures you can look up. What the rating is worth cannot be worked out at all: one programme states outright that a rating earns points at a rate the programme keeps to itself, and no programme we could read publishes what a point hands back when you come to spend it.

I spent years on a casino floor, and what people get wrong about this card is which way it points. They think the casino is giving them something. It is the other way round: you hand over a record of your own money, and the casino keeps the copy.

That is not an argument against carrying a card. It is an argument for knowing what goes on the card before you hand it over.

What the card writes down

Feed the card into a slot machine and the counting is plain arithmetic: Casino of the Rockies grants one point for every dollar of slot play. That dollar earns its point whether the spin pays you or takes the money, because what the machine counts is the dollar going in, not what comes back out.

Put the same dollar into an electronic table (a terminal where you bet on a game run by a screen instead of a dealer; the smallest bets are often lower, and how fast one runs is not published) and it earns fewer points. How many fewer is a rate each programme sets for itself.

The slot rate is the same everywhere; each programme picks its own rate for screen games. How many points a dollar earns tells you nothing about what the dollar costs you.

Onto a live table nothing is scanned at all. You give the card to the dealer, and a record of your evening is built by hand, out of what a member of staff can see from where they are standing:

A person builds that record, not a machine. A supervisor walks past the table, looks at the chips in front of you and writes a number down for your average bet. Casino Niagara says exactly that in the terms of its own programme: points are granted on the personal observations of staff, and those observations are subject to error.

And the record only holds what somebody saw. The card goes into the reader at a machine, or into the dealer’s hand at a table, before the first bet of the session. An hour played with the card in your pocket is an hour nobody wrote down, and the programme says plainly that play it did not track is your loss rather than its own.

The cost line reads the same on both screens; the record line does not. What the hour cost you was decided by the game and by the bet you chose, so that figure is identical whether the card went into the reader or stayed in your pocket. What the card wrote down is the one line a card left in your pocket changes, and it changes that line to nothing at all.

The same three numbers as the price of an hour

Every programme we could read rates a table player on your average bet, how long you play and the game — the same three numbers that make up the price of an hour (bet, times rounds an hour, times the house edge: what an hour of a game costs on average).

Every row starts with your average bet, which is why raising it to make the record look larger moves two figures at once:

One rating table of exactly this kind is public — how many hands an hour each game deals, and what an hour of it is worth in comps. It reached Wizard of Odds anonymously from an executive at a Strip casino, and that rating table is where the 70 hands an hour come from.

A point has a price

A point is not a unit of reward. A point is a unit of turnover (all the money that goes over the table in an evening: the same dollars again and again): a programme grants one for a dollar of your own money going through the machine, and that dollar has a price, because the machines keep a share of everything put through them. BCLC puts the average return of those machines at 92%.

2. What the card counts1 pointgranted for that dollar, whether the spin paid you or took it.
3. What the dollar costabout $0.08on average, once the share the machines keep over many spins is taken off.

Multiply what one dollar costs by the number of points sitting on your card, and the count becomes a price list:

An average over many spins, not a forecast of one evening: the machines keep 8% of everything put through over the long run, and a single evening lands well away from that either way. A count of points answers one question: what did this count cost to produce?

A count of points does not keep, either. 4 of the programmes we read put a clock on something the card holds for you, and no two of those clocks run the same way.

One programme on this list runs two clocks at once: one for the points you have earned, and another for the level, which it works out again every January from the play of the year before. Both of the programmes that run a clock on a level run it the same way: the level comes out of the play you did inside one window, and it is set again when that window closes. That is why a level measures how fast you played inside one window, and not how long you have been a member.

Who holds the record

The card is not anonymous and was never meant to be. Casino of the Rockies wants photo identification along with the application form, and for every membership and programme transaction Great Canadian Entertainment wants government photo ID (a card issued by a government showing your photo and your date of birth: a driver’s licence, a passport, a provincial ID card). From the moment the card is issued, the record of your betting has your legal name attached to it.

One operator’s notice of collection calls the record gaming-related personal information, collected under a named section of a provincial statute. The same notice uses it to run the loyalty programme, to share with regulators and law enforcement where the law requires it, and for responsible gambling: analytics of your own play and feedback to you on it — the one use that works for you rather than on you.

The same record cuts the other way as well, and this is the part people do not expect. Great Canadian writes that a player who self-excludes has the membership suspended immediately and the outstanding balance forfeited.

Nothing here is a reason to put off self-exclusion — the door closing is the point of it, and a forfeited balance is a smaller loss than the one the programme is there to prevent. It is a reason to read that line first, and to spend anything already sitting on the card before you sign.

What the record buys

One word in all of this does have a published rule behind it, and the word is “free”. An advertisement must not describe a game, an offer or a bonus as free when a person has to risk or lose money to take part: the code of the industry’s own association says so outright. That gives you a test you can run at the counter, in three steps:

1. Step oneRead what taking the offer asks of youEither there is a bet you have to place with money of your own, or there is not.
2. Step twoIf money of your own has to go in first, the code forbids the wordWhat the code forbids is the word, not the offer: an offer may ask for a bet, and an advertisement for it may not be called free.
3. Step threeRead the word as a description of the part you pay forThe bet the offer asks for is the part the word is not describing, and that bet is the part that comes out of your own pocket.

What the card does not do

It is easy to assume that a machine treats a member differently from a stranger. What can actually be checked is the standard the machine is built to: AGCO puts a floor under a game’s return and requires that floor to be met for every available bet configuration. So the check is about the game, and about each bet option the game offers, and not about whoever is sitting in front of the machine:

Your card, your membership and the level you reached are not named anywhere in the standard we read.

Worth being exact about what this is and what it is not. The floor is a rule the machine is built to, checked by a regulator; it is not a promise from any casino. No operator we could read puts it in writing that a card makes no difference to a machine — we looked for that sentence and did not find it — so the honest place to take this from is the standard, and not from anybody’s word.

Practice: points follow the betting

Every moment here has the same shape: the card has counted something, and the question is what that count cost. Nothing is scored, and there is nothing to unlock — what is being practised is a decision about money rather than a skill, and a percentage at the end would be pretending otherwise.

Nothing asks for the number on your own card, and nothing you choose is sent anywhere.

One thing to do before your next visit, and it takes a minute. Decide the stake and the time — Game plan walks you through it. Then, whatever the card says at the end of the evening, the stake and the time are the two numbers you keep.

If you notice yourself adding a spin or a hand because of a number on a screen, that is worth saying out loud to someone. The lines below are for exactly that conversation, and they are confidential.
