Atlassino Academy · How casinos work · Lesson 2 of 8
What an hour of play costs
The house edge is a price per bet. An hour turns it into a bill, and two numbers do that: how much you bet, and how many rounds the table deals while you sit there.
Two people sit down at the same baccarat table with $10 a hand each. One puts the chips on the Banker box, the other on Tie. Same dealer, same speed, same money. How far apart are their two hours?
The short answer
Three numbers decide what an hour costs: the bet you make, the rounds the table deals while you sit there, and the house edge — the share the game keeps of every bet. Multiply the three and you have the bill. The bet is yours. The house edge belongs to the game, and you choose it twice over before the first bet and never again. The rounds an hour belong to the table, and they are the number nobody counts.


Leoformer dealer · rules and maths
People hear that the casino keeps a small share of every bet, and they file the whole thing under “small”. A small share of one bet really is nothing. The same share off every bet, round after round, for a whole evening, is a number you would have wanted in advance.
An hour is three numbers multiplied
A price is charged on every bet you make, and it is the house edge (the share of every dollar bet the casino keeps on average, over many rounds). It comes off the money you put down before the cards or the dice come out, which is what makes it something you can multiply.
A double-zero wheel at one example bet.
The three multiply, so halving any one of them halves the hour.
The bet: yours, every round
The table sets a floor under the bet, printed on the sign as the minimum (the smallest bet the table takes, for each bet on your spot). Reading one is a lesson of its own. Above that floor the bet is yours, and the bet is the only one of the three you set again on every round (one full go of the game: bets down, cards or dice, then settling).
A smaller bet buys a cheaper hour, and a smaller bet does not buy more hours. How much money the evening gets is a separate decision, settled before you go: your limit (the money and the time you decide on before you go: a ceiling, not a target). The Game plan tool writes that limit down, and Decide the money before you go is the lesson on choosing it.

Mayaformer floor supervisor · manners, money and breaks
Before you sit, work out the hour, not just the limit. The limit says how much can go. The hour says how fast. Two different questions, two different answers — write both down.
It takes a minute at the kitchen table and it is impossible on the floor.
The house edge: chosen twice, then fixed
- First you choose the gameBaccarat rather than roulette, craps rather than sic bo. The game you sit down at settles which house edges are on offer at all, and a game you never sit down at cannot charge you anything.
- Then you choose which bet to make inside that gameOn one baccarat table the Banker box and the Tie box carry house edges of very different sizes, and the box the chips land on is the whole of the choice.
- After the chips are down, nothingThere is no way of playing a baccarat hand that moves the house edge, and no amount of watching the table moves it either.
| The chips go on | House edge | An hour |
|---|---|---|
| the Banker box | 1.06% | $7.63 |
| the Tie box | 14.36% | $103 |
One game asks something of you, and only one. Blackjack hands you a decision (a choice you make after the bet is down that changes what the round costs on average; roulette and baccarat have none). The blackjack figure further down is the price for a player who plays every hand by the chart; without the chart it is several times larger — not a reason to stay away, a reason to know which of the two you are.
Rounds an hour: the table’s
The number nobody counts is the rounds an hour (how many rounds a table gets through in an hour, which is what turns a bet into an hourly cost), and the rounds an hour are regularly the largest of the three.
And one game is not one number of rounds. Fill the seats and the same wheel slows right down.
| At the table | Spins an hour | An hour costs |
|---|---|---|
| Just you | 112 | $59 |
| 2 playing | 76 | $40 |
| 3 playing | 60 | $32 |
| 4 playing | 55 | $29 |
| 5 playing | 48 | $25 |
| 6 playing | 35 | $18 |
No source we could read has timed a Canadian table and published the count. The rounds an hour here come from the Las Vegas Strip rating table — the sheet a casino uses to rate its players — so take them as the shape of the thing, not as a measurement of the table in front of you.
A wheel with nobody else at it is the easiest one to follow and about 3.2 times dearer by the hour, at the same bet in the same seat. A quiet wheel being the easiest one to follow and a quiet wheel being the dearest by the hour are both true at once, and neither of those facts is a reason to pick one wheel over another. The rounds an hour are not yours to move; how long you stay is, and half the rounds you sit through is half the bill.
Machines are the extreme case. A reel machine settles about 600 spins an hour — as fast as the machine allows, one every six seconds — and at $1 a spin that turns the cheapest-looking seat on the floor into one of the dearest hours in the room. The figure is what the device permits, not how fast anybody plays.
| What is published | Of the money put through |
|---|---|
| The average across one province’s machines | 92% |
| The least a machine in another province may return | 85% |
One seat cannot be priced at all: an electronic table — a terminal running the same wheel on a screen — because no source we could read publishes its rounds an hour.
The three numbers, game by game
The same multiplication for the games a Canadian room usually deals, at one example bet.
| Table | An example bet | Rounds an hour | House edge | One round |
|---|---|---|---|---|
| Blackjackevery hand by the chart | $10 | 70 | 0.53% | $0.05 |
| Slot machinea reel machine | $1 | 600 | 8.00% | $0.08 |
| Baccaratthe Banker bet | $10 | 72 | 1.06% | $0.11 |
| Crapsthe pass line | $10 | 18 | 1.41% | $0.14 |
| Rouletteone green pocket | $10 | 35 | 2.70% | $0.27 |
| Sic bothe Small bet | $10 | 45 | 2.78% | $0.28 |
| Roulettetwo green pockets | $10 | 38 | 5.26% | $0.53 |
| Baccaratthe Tie bet | $10 | 72 | 14.36% | $1.44 |
The same bets over an hour, dearest first. A long-run average, not a prediction of one evening.
It is not the same order. A spin of a reel machine costs $0.08 and a round of the Tie bet costs $1.44 — but give both an hour and they are only 2.2 times apart, with the machine second-dearest in the room. Nothing about the machine changed except how often a spin happens: 600 spins while the table deals 72 hands. A price per round and a price per hour are two different questions, and only the price per hour is about an evening.
The same figures, arranged for a different question — which table to sit at on a first visit — are in Which table for a first visit.
An average, not a forecast
$20 an hour does not mean you will be $20 down when the hour is up. It means that if the same hour were played thousands of times over, the average of all those hours would land about there.
- The average is not tonight’s billone hour lands anywhere, above the average or below it, and how far it strays is its own lesson later in this track
- The average is not a floor or a ceilingnothing holds a single evening to the average in either direction
Nothing here says that a cheaper hour is a good idea, or that any hour is. An hour has a price on average, which is a fact about the game and not a suggestion about you.
An hour, game by game, on one card
That is the lesson. The price of an hour at each game is a list worth having to hand when you choose a table, so here it is on one card.
| Table | An example bet | Rounds an hour | House edge | An hour |
|---|---|---|---|---|
| Crapsthe pass line | $10 | 18 | 1.41% | $2.54 |
| Blackjackevery hand by the chart | $10 | 70 | 0.53% | $3.68 |

An hour = the bet × rounds an hour × the house edge. An average over many hours, not a forecast of one.

Practice: same money, different bill
Two hours stand side by side, and you say which one costs less. On level 1 exactly one of the three numbers is different: 10 moments. On level 2 more than one moves at once, so the answer needs the multiplication rather than a glance: 8 moments. Level 3 is 7 things that happen at a table — which of the three numbers moved, and whose was it — and nothing there is scored.
The lesson is one run: every square on the strip below is one moment of it, and they are all there from the start. Only your first answer on each moment counts, and when a level’s squares are full the next level begins by itself.
Press a card itself or use the row of buttons below it. Every amount is an example bet, not the minimum of any casino: what a real table asks is on its sign. Two hours count as about the same when they are within 15% of each other — our rule, and it is on the screen.

The answer: About the same.
More than one of the three numbers is different here, and all three multiply the hour. The left card works out at about $10 an hour and the right card at about $9.46 — within 15% of each other, which is where this practice table stops calling either card the cheaper hour. The difference over the whole hour is $0.54.

An hour costs the bet, times the rounds an hour, times the house edge. The amounts are example bets, not the minimum of any casino.
Four more people sit down at your roulette table. Whose number just moved?
The answer: The table’s — the rounds an hour, and the floor under the bet.
A wheel with six people playing spins fewer times in the hour than a wheel with two, so the same bet is made fewer times in the hour. Nothing you did moved the rounds an hour, and nothing you can do will move them back. So it is the table’s number, and the hour costs less.

Every moment is worked out the same way, and nothing in the practice table is typed in by hand: the bet, the rounds an hour and the house edge are multiplied by the same code as our own tool for the price of an hour.
How the practice table works
Where the answers come from. Nothing is typed in by hand. Each card carries three numbers, and the answer is the smaller of the two products — worked out by the same function as our own tool for the price of an hour, from the same published figures as the table above. On level 3 the answer is which of the three numbers the situation touched, and the reason says why.
What the cards may say. Our code refuses to build a card at an amount outside the example bets this course uses, refuses a card for a seat whose rounds an hour no source we could read publishes, and on level 1 refuses a pair where more than one of the three numbers differs.
One strip, no rounds. Every square on the strip is one moment of this lesson, and they are all there from the start. Your first answer fills the square; when a level’s squares are full the next level begins by itself, with no button in between. Practising a mistake turns a cross into “fixed in practice” and does not change the count: only first answers do. Level 3 has no squares and no score.

One line to take with you. Before you sit, multiply: the bet you mean to make, the rounds that table gets through, and the house edge on the bet you mean to make. If the answer is bigger than you expected, the move is a smaller bet or a shorter sitting.
Not a faster table to make it back. That is the same three numbers pointing the other way.

How it’s worked out
Sources, numbers and hosts
Where this starts, and which games it covers. The house edge arrives on this page as a finished number: the share of every bet the casino keeps. Where that share comes from is The price in every bet, the lesson before this one. How to play a game is not taught here at all — each game has a track of its own.
Numbers. Every figure on this page is calculated, and each one is recalculated by a test against the engine rather than against this page. The price of an hour is the bet, times the rounds an hour, times the house edge — the same function our own Price of an hour tool uses, on the same published figures.
The blackjack figure is ours, and it differs from the tool’s on purpose. This course prices blackjack from the rulebook BCLC publishes, solved by our own engine: 0.5262% for somebody who plays every hand by the chart, which is $3.68 an hour at $10. Our Price of an hour tool prices a different table — the one in the published table by number of decks, which shuffles after every hand and re-splits aces — and gets a slightly larger figure. Two different tables, not two answers about one, and the document behind this one is pinned by checksum in our rules files.
Sources. Two kinds. The house edge of each bet is published by a reference on the mathematics of casino games, quoted at the row it belongs to. The rounds an hour come from two published tables, neither of them Canadian: a rating table one casino uses for comps, and a set of tables from a casino-management textbook, both behind the source buttons beside the figures, with their publisher and the date we read them. Pretending an estimate is a local measurement would be worse than having no figure at all. From the rating table this course takes the rounds an hour and never the house-edge column printed beside it: its own author notes that column reflects players’ mistakes and the average kind of bet made, rather than the figures used here.
What is deliberately missing. No rounds an hour for an electronic table: nobody we could read publishes it, and an hour cannot be priced without it. No figure for how long people usually play — that is not ours to suggest, and no source we trust publishes it. No claim about which casino is cheaper: the amounts here are example bets, and what a real table asks is on its own sign, on the day. No “hold” and no share of the money brought to the cage: that is a different measurement and the next lesson of this track.
Hosts. Leo and Maya are illustrated characters. Their backstories, a former dealer and a former floor supervisor, are written for the course: neither is a real person, and neither speaks for any casino. The rules and numbers on this page come from the sources it cites, not from their experience.
No promise. Knowing what an hour costs makes the price of an evening knowable in advance. It does not make any evening cheap, and nothing on this page says that spending one is a good idea for you.
