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?

Before we start: how far apart?

Nothing is scored here. We come back to it at the end.

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.

Leo and Maya stand at the rail beside three small tiles laid out on the empty cloth: a plain ring, a clock face with no numerals, and a circle with one narrow wedge cut out of it.
Leo smiling, explaining with an open hand.

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 bet, times the rounds the table deals in that hour, times the house edge, makes what the hour costs.

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.

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

  1. 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.
  2. 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.
  3. 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.
One baccarat table, $10 a hand, 72 hands an hour. The only thing that changes is the box the chips land in: they move to the box beside the one they were on, and the hour changes by $96.

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.

One wheel with two green pockets, one bet of $10 a spin, and the only thing that changes is how many people are sitting there.

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.

A floor and an average answer two different questions, and reading a floor as an average flatters the machine.
What is publishedOf the money put through
The average across one province’s machines92%
The least a machine in another province may return85%

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.

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.

What an hour costsAn example bet, game by game

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. Progress stays in this browser; nothing is sent anywhere.

Five quick ones. Pick an answer, then check it. No timer, no points: just whether it stuck.

1Of the three numbers in the price of an hour, which one is yours?

Show the answer

Answer: The bet. All three multiply, so neither the bet, nor the rounds an hour, nor the house edge is the big one in general. Only the bet is a decision you make on every round.

  • The bet Above the table’s minimum the bet is yours and nobody else’s, and the bet multiplies the whole bill: halve the bet and the hour costs half. What the minimum is, and where it is written, is the lesson on the table sign.
  • The rounds an hour Mostly the table’s: the dealer, the shuffler, and how many people are sitting there. You choose the game, and you choose how long you stay at the table — the rest of the rounds an hour is not yours.
  • The house edge You choose the house edge twice over — once when you choose the game, once when you choose which bet to make inside that game — and after that nothing you do moves it. On one baccarat table the Banker box and the Tie box are 1.06% and 14.36%, and that is a choice; there is no play that changes either figure.
2The same baccarat table, the same $10 a hand, the same 72 hands an hour. The chips go on Banker or on Tie. How far apart are the two hours?

Show the answer

Answer: About 13.5 times: roughly $7.63 against roughly $103. Nothing about the table changed. The house edge did, and the house edge is settled every time the chips go down on one box rather than another.

  • The Tie is cheaper: it is one bet instead of many It is one bet either way — the same 72 hands in the hour. How much a payout returns, and how often, is the lesson on the language of odds; the price per bet is settled before that.
  • About 13.5 times: roughly $7.63 against roughly $103 Two of the three numbers are identical, so the hours differ by exactly as much as the edges do: 1.06% against 14.36%.
  • A little apart: it is the same table and the same money The rounds an hour and the bet are two of the three numbers, and both of those are the same here. The house edge is the number that is not the same here: it is settled by the box the chips land on, and between the Banker box and the Tie box it moves by more than tenfold.
3A double-zero wheel, $10 a spin, 38 spins an hour — about $20. Two ways to spend the next hour: $5 a spin at the same wheel, or $10 a spin at a wheel with one green pocket (35 spins an hour). Which hour costs less?

Show the answer

Answer: About the same: $10 against $9.46. Within 15% of each other counts as about the same here — our rule, and the practice table uses it too.

  • The single-zero wheel, by a long way It is cheaper, but only by $0.54 an hour against the half-bet hour. Both are about half of the $20 we started from.
  • About the same: $10 against $9.46 Halving the bet halves one number and nothing else. Moving to the other wheel changes two — 5.26% to 2.70%, and 38 spins to 35 — and the two changes multiply to almost the same result.
  • Half the bet, by a long way: the bet is the biggest number No number in the product is bigger than the others; they multiply. Cutting the edge nearly in half does about as much as cutting the bet in half.
4The same $10, two different tables: the pass line at craps and the Small bet at sic bo. Which hour costs more, and by roughly how much? new situation

Show the answer

Answer: Sic bo, about $13 against about $2.54 — near enough twice. Same bet, near enough the same rounds an hour: when the bet matches and the rounds an hour nearly match, the house edge decides the evening by itself.

  • Sic bo, about $13 against about $2.54 — near enough twice The rounds an hour are almost the same, 45 rounds against 18, so the house edge does all the work: 2.78% is nearly double 1.41%.
  • The same: the bet is $10 at both The bet is one number of three. Here the rounds an hour nearly match and the house edge does not, so the two hours do not match either.
  • Craps, because dice are thrown faster there The line bet settles 18 times an hour against 45 rounds of sic bo. Three rounds cannot outweigh a house edge nearly twice as large.
5A dollar a spin on a reel machine, or $25 a hand of blackjack played by the chart. Which hour costs more on average? new situation

Show the answer

Answer: The machine, by a long way: about $48 against about $9.21. 600 spins an hour is as fast as the machine allows — about one every six seconds, timed by researchers on reel machines — not a measured average of how people play. Halve it and the machine’s hour is still the dearer one.

  • The blackjack table: $25 a hand is the bigger bet The bigger bet is one number of three, and here the rounds an hour and the house edge both go the other way.
  • The machine, by a long way: about $48 against about $9.21 The bet is a twenty-fifth of the other one and the hour still costs several times as much, because the machine settles 600 spins where the table deals 70 hands. The rounds an hour are the number nobody counts.
  • About the same: a dollar is small change A dollar 600 times is $600 put through the machine in the hour, against $1,750 across the table. Less money staked, at fifteen times the house edge, and the machine’s hour is still the dearer one.

The question we opened with. More than ten times apart: about $7.63 an hour on the Banker box against about $103 on Tie — 13.5 times, a gap of $96. One table, one dealer, one bet size, and the only thing that moved was the box the chips landed in.

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.
