To One vs For One Odds

The difference between "to one" and "for one"

When a casino tells you what a bet pays, it uses one of two phrasings, and they are not the same thing even when the numbers look similar.

"To one" describes your profit. If a bet pays 35 to 1, your profit is 35 times your wager, and you also keep your original stake. This is the format used on the classic roulette pay table: one specific number pays 35 to 1, a wager on two specific numbers pays 17 to 1, and a wager covering six specific numbers pays 5 to 1¹.

"For one" describes the total return. If a bet pays 9 for 1 and you wager the same JPY 1,000, you receive JPY 9,000 in total, and that JPY 9,000 includes your original stake. Your actual profit is only JPY 8,000.

The trap is that the "for one" number is always one bigger than the equivalent "to one" number, so a pay table written in "for one" style looks more generous at a glance than it really is. The baccarat tie bet is the classic example: almost all casinos pay 8 to 1 on a tie, which is often expressed as the equivalent to 9 for 1². Same money, different headline number.

A quick way to remember it:

• "To one": you get your stake back plus the stated multiple. 35 to 1 on JPY 1,000 = JPY 36,000 in your hand.
• "For one": the stated multiple is the total. 9 for 1 on JPY 1,000 = JPY 9,000 in your hand, of which JPY 1,000 was yours to begin with.

If you see a pay table and cannot tell which format it uses, look at the even-money bets. If the simplest bet on the table is quoted as "1 to 1," the table is using "to one." If it says "2 for 1" on the same bet, you are looking at "for one" wording.

How "to one" payouts work

The "to one" format is the standard on table-game layouts and in most official game rules across Asia and beyond. A few real examples show how it reads.

Roulette. The UK's statutory roulette rules set the payouts: one specific number pays 35 to 1, two specific numbers pay 17 to 1, and six specific numbers pay 5 to 1¹. Bet on a single number and it hits, and you collect 35 times your wager in profit plus your stake back.

Sic bo. The same style of rules govern the dice game sic bo, common in Macau and across the region. A single dice bet pays 1 to 1 if your chosen number appears on one die, 2 to 1 if it appears on two, and 3 to 1 if it appears on all three; a specific two-dice combination pays 6 to 1; a specific double combined with a single number pays 50 to 1; and the Small bet (total of 4 to 10, excluding a triple) pays 1 to 1³. Hopping bets in craps follow the same pattern: 33 to 1 for a specific pair combination and 16 to 1 for a specific non-pair combination³.

Baccarat. A winning bet on the Player side pays 1 to 1, and a winning tie bet pays 8 to 1⁴. The optional Pairs side bet wins 11 to 1 if the first two cards for the Player or Banker are an identical pair⁵.

Casino War. Winning tie bets pay 10 to 1⁶.

Blackjack. Japan's casino rules for twenty-one quote everything "to one": a winning hand other than blackjack pays 1 to 1, insurance pays 2 to 1, and a pair side bet pays 11 to 1⁷. The pair bet can be finer-grained: 25 to 1 for a pair of the same suit, 12 to 1 for a diamonds-and-hearts or spades-and-clubs pair, and 6 to 1 for any other pair⁷.

Craps. Pass line and come bets pay 1 to 1⁸, and the odds bet behind them pays 2 to 1 on a point of 4 or 10, 1 to 1.5 on 5 or 9, and 1 to 1.2 on 6 or 8⁸. Place bets pay 1 to 1.8 on 4 or 10, 1 to 1.4 on 5 or 9, and 1 to 1.2 on 6 or 8⁸. Note that these fractional "1 to 1.8" figures mean your profit is 1.8 times your stake.

Macau side bets. In Macau's blackjack rules, the Over 13 or Under 13 side bet pays 1 to 1⁹, and the Any Pair side bet pays 1 to 11⁹. Dragon-Phoenix, a Macau dice game, pays 1 to 1 on Dragon or Phoenix, 1 to 25 on the "5 odds" bet, and 1 to 7.5 on the thrower's spinners bet¹⁰.

Roulette's American cousin. The American roulette top line bet pays 6 to 1, compared to the European game's better-value even-money and column bets¹¹.

Layout inscriptions. Regulated blackjack tables in New Jersey spell it out right on the felt: "Blackjack pays 1 to 1" (a rule variation), "Insurance pays 2 to 1," and, for the streak side bet, "Two consecutive wins pays 3 to 1, three consecutive wins pays 7 to 1, four consecutive wins pays 17 to 1, five consecutive wins pays 37 to 1"¹². Blackjack Switch's match side bet runs from 1 to 1 for one pair up to 40 to 1 for four cards of the same number⁷.

In every one of these cases, the stated multiple is profit. Your stake comes back on top.

How "for one" payouts work

"For one" wording is less common on felt layouts but appears in craps, in older European rules, and in machine pay tables. Here the number is the total handed back, stake included.

The clearest official example comes from Luxembourg's 1979 craps rules, which define the "don't win" bet associated with the point: the wager is paid 1 for 2 if the point is 4 or 10, 2 for 3 if the point is 5 or 9, and 5 for 6 if the point is 6 or 8¹³. Read that carefully. A bet paid "1 for 2" means you hand over 2 units and get 1 unit back in total. That is not a win at all in the usual sense; it is the wording used for lay-style bets where you risk more than you stand to gain, because the bet is favored to win. The "for-one" phrasing makes this natural to express: the total return is simply a multiple of a single unit.

The baccarat tie shows the other face of the format. A casino paying 8 to 1 on the tie may describe it as 9 for 1². The total returned on a winning JPY 1,000 tie bet is JPY 9,000 either way: JPY 8,000 profit plus your JPY 1,000. The "for one" figure counts your stake as part of the payout.

This is why "for one" numbers can mislead. A pay table listing "9 for 1" next to another bet at "8 to 1" looks like the 9 is the better offer, but they are identical. And a machine pay table showing "300 for 1" on a jackpot is really paying 299 to 1.

The place-bet figures quoted in some craps guides, "1 to 1.8" and so on⁸, are simply "to one" wording with fractional profit figures: "1 pays 1.8," meaning one unit staked earns 1.8 units of profit, with the stake returned on top. That is ordinary "to one" quoting with fractions, and it is a good reminder to always check whether the figure includes your stake. If you want the general background on which odds include the stake, see stake, profit and return.

Converting between the two formats

The conversion is one step:

• "For one" to "to one": subtract 1. 9 for 1 = 8 to 1. 6 for 1 = 5 to 1. 2 for 1 = 1 to 1 (even money).
• "To one" to "for one": add 1. 35 to 1 = 36 for 1. 8 to 1 = 9 for 1.

So when a pay table says a bet "pays 6 for 1," your profit is 5 times your stake. That is exactly the same as 5 to 1.

The same total-versus-profit distinction runs through every other odds format you will meet in Asia. Decimal odds, used by the Hong Kong Jockey Club and most sports operators, are "for one" in spirit: the decimal figure is the total return per unit staked. A HKD 1,000 bet on Barcelona to win at home at decimal odds of 2.10 pays HKD 2,100 including the stake¹⁴. An All Up combining three home wins at 1.40, 1.95 and 2.40 turns HKD 1,000 into HKD 6,552 (1,000 × 1.40 × 1.95 × 2.40), stake included¹⁵.

Other operators quote the same idea in their own currency and style. Korean boat racing shows a worked example on its dividend boards: a KRW 2,000 single-win bet on player 1 at odds of 1.2 returns KRW 2,400 (2,000 × 1.2)¹⁶. Japanese boat race odds work the same way: predicting the finishing order 1-3 at a payout of 8.4 returns 8.4 times your bet¹⁷. Fixed-odds football examples follow suit: HKD 100 on a 2:1 correct score at odds of 7.50 pays HKD 750¹⁸, and a handicap bet can return HKD 155 for a HKD 100 home win, HKD 400 for the draw, or HKD 430 for the away win, all including stake¹⁹.

Pari-mutuel boards are "for one" as well. Tote win odds are displayed on a $1.00 CAD base at Ontario tracks²⁰, meaning the number shown is the total dividend per dollar. Japanese horse racing works the same way: odds at Kasamatsu Keiba change from moment to moment as money enters the pools, and the displayed figure is the payout per unit staked²¹. For a fuller treatment of how those dividends are built, see pari-mutuel dividends and decimal odds.

The one thing to watch is that in all these formats the stake is inside the number. If you are comparing a "to one" casino pay table against a decimal sports price, convert first: a decimal price like 6.00 for a home-home halftime-fulltime result² already includes your stake, while a "to one" figure does not.

House edge: the percentage of your original bet the casino keeps

The house edge is what the casino expects to keep, on average, from each bet, expressed as a percentage of your original wager. It is the gap between what a bet should pay given its true probability and what it actually pays.

Baccarat gives the cleanest illustration, because its three main bets have very different edges.

The tie pays a headline 8 to 1 (or 9 for 1), but its true odds are much longer than that, so the casino keeps roughly 14 cents of every dollar wagered on it, versus about one cent on Banker.

The payout itself moves the edge. If the tie pays 9 to 1 instead of 8 to 1, the house edge on it drops to 6.385% with one deck and 4.844% with eight decks². One extra unit of profit, same bet, edge cut by more than half. That is how much the quoted payout matters.

Craps place bets show the same spread. The house edge is 6.67% when the point is 4 or 10, 4% when it is 5 or 9, and 1.52% when it is the 6 or 8⁸. The payouts differ accordingly (1 to 1.8, 1 to 1.4 and 1 to 1.2), and the true probabilities differ too.

To work out a house edge yourself from a payout:

1. Convert the payout to profit-per-unit-stake (subtract 1 from any "for one" figure).
2. Find the true probability of winning.
3. Multiply the profit by the probability of winning, and subtract the stake times the probability of losing. The result, as a percentage of your stake, is the expected loss per bet, which is the house edge.

For example, a bet paying 6 for 1 is really 5 to 1. If its true chance of winning is 1 in 7, the fair payout would be 6 to 1, so the casino is shorting you one unit of profit on every win, and that shortfall is where the edge comes from. For the general method, see expected value in betting.

Why a higher house edge favors the casino

The house edge is the casino's price for the game. Over a single bet it is invisible; you either win or you don't. Over hundreds of bets it is close to certain: the higher the house edge, the more favorable the casino is compared to the player³. A bet with a 16% edge, like the worst craps proposition bets, costs you far more over a session than a bet with an edge near 1%⁴.

That is why the tie bet in baccarat is worth understanding even though its 8 to 1 (or 9 for 1) headline is the biggest number on the layout. The bigger payout comes with much lower odds of winning, and Casino War's own rules make the point plainly: higher payouts mean lower odds of winning, so placing tie bets to win back losses is not a winning strategy⁶. The casino is not being generous with the big number; it is pricing a longshot.

The same logic explains why casinos can offer side bets at all. A pair bet at 11 to 1, a streak bet at 37 to 1, a sic bo combination at 50 to 1: these are all longshots whose payouts are set below the true odds, and the gap is the edge. The main bets tend to carry low edges: blackjack runs 0.5 to 2% and baccarat 1.06 to 1.24%⁵, while side bets typically carry a higher house edge than the main game⁶, and craps proposition bets reach 16% or more⁴.

Where you will see each format in practice

"To one" is the table-game standard. Roulette layouts (35 to 1), baccarat (1 to 1 and 8 to 1), sic bo (1 to 1 through 50 to 1), blackjack (1 to 1, insurance 2 to 1), craps (pass line 1 to 1) and their side bets are all quoted this way in the official rules of the UK, Japan, Macau and New Jersey alike¹. If you learn one format, learn this one.

"For one" appears in specific corners. The Luxembourg craps rules' "1 for 2, 2 for 3, 5 for 6" lay bets are the classic example¹³. The baccarat tie is "often expressed as the equivalent to 9 for 1" in casino literature². Machine pay tables, some video poker schedules and some US craps prop-bet wording also use "for one," because the machine simply credits a total amount.

Decimal odds are "for one" in disguise. Every sports price you see at HKJC, Singapore Pools, Korean boat racing or Japanese boat race is a total-return multiple: 2.10 pays HKD 2,100 on HKD 1,000¹⁴, 1.2 pays KRW 2,400 on KRW 2,000¹⁶, 8.4 pays 8.4 times your stake¹⁷. If you already read decimal odds comfortably, you already understand "for one."

Pari-mutuel dividends are "for one" too. Tote boards show the dividend per unit staked, on a $1.00 base at Ontario tracks²⁰ and per ¥100 or ¥50 unit in Japan, where the figure fluctuates until the pools close²¹. Racecourse odds cards print the odds for all bets from Win to Trio on one card²².

A practical habit. When you sit at a new table or open a new pay table, find the even-money bet and check whether it reads "1 to 1" or "2 for 1." That single check tells you which convention the whole table uses, and from there every other number on the layout makes sense. And when comparing a casino pay table against a sportsbook price, remember the stake: 8 to 1 and 9 for 1 are the same bet wearing two different outfits.
