Free Odds in Craps: The Best Bet You've Never Heard Of

Most casino games are designed so that every wager on the table carries a house edge. That's simply the economic reality of gambling. But craps has a remarkable exception buried inside it — a bet so mathematically pure that the casino makes zero profit on it. It's called the free odds bet, and understanding how it works could genuinely change how you approach the craps table. Players at online casinos offering live craps, such as Hotbet.se, often discover this bet for the first time and immediately wonder why nobody told them about it sooner. The answer is straightforward: casinos have no financial incentive to advertise a wager on which they earn nothing.

What the Free Odds Bet Actually Is

Before you can place free odds, you need to understand the basic structure of a craps game. When you walk up to a craps table, the first wager most beginners make is the Pass Line bet. You put your chips on the Pass Line before a new round begins. The shooter then rolls the dice for what's called the come-out roll. If the result is 7 or 11, Pass Line bettors win immediately. If the result is 2, 3, or 12 — collectively known as craps — Pass Line bettors lose immediately. Any other number (4, 5, 6, 8, 9, or 10) becomes the Point.

Once a Point is established, the game shifts. The shooter must roll that same Point number again before rolling a 7. If the Point hits first, Pass Line bettors win. If a 7 appears first — called a seven-out — they lose. This is the fundamental rhythm of craps.

Now here's where free odds enter the picture. Once a Point has been established, you are allowed to place an additional bet directly behind your Pass Line chips. This secondary wager is the free odds bet. It pays at true mathematical odds — meaning the casino has no edge on it whatsoever. It is, in the strictest sense, a fair bet.

Why It Pays True Odds

The concept of true odds refers to the actual probability of an event occurring. When a casino pays true odds, it means the payout perfectly reflects the real likelihood of winning, with no margin skimmed off for the house.

Each Point number has a specific probability of being rolled before a 7, and the free odds bet pays according to those exact probabilities:

• Point of 4 or 10: There are three ways to roll a 4 (1-3, 2-2, 3-1) and six ways to roll a 7. The odds against making the point are 2 to 1, so free odds pay 2:1.
• Point of 5 or 9: There are four ways to roll a 5 and six ways to roll a 7. The odds are 3 to 2 against, so free odds pay 3:2.
• Point of 6 or 8: There are five ways to roll a 6 and six ways to roll a 7. The odds are 6 to 5 against, so free odds pay 6:5.

These payouts are not rounded or adjusted in the casino's favour. They are precise reflections of the mathematical reality, which is what makes this bet genuinely unique in the casino world.

How Much Can You Bet on Free Odds?

Here is where individual casinos have significant control. The free odds bet is always capped at a multiple of your original Pass Line wager, and that multiple varies from one casino to the next. Common structures are:

• 1x odds: You can bet up to the same amount as your Pass Line stake.
• 2x odds: You can bet up to twice your Pass Line stake.
• 3-4-5x odds: This is a popular format where the allowed multiple depends on the Point. You can bet 3x on points of 4 or 10, 4x on 5 or 9, and 5x on 6 or 8. This structure is designed so that a winning free odds bet always pays exactly 6 times your Pass Line stake, making chip management simple.
• 10x, 20x, or even 100x odds: Some casinos, particularly in Las Vegas, have historically offered very high odds multipliers as a competitive differentiator.

The higher the odds multiple offered, the better it is for the player. As you increase the proportion of your total action riding on the zero-edge free odds bet (compared to the portion on the Pass Line, which does carry a house edge), you mathematically dilute the overall house advantage on your combined wager.

Calculating the Combined House Edge

The Pass Line bet by itself carries a house edge of approximately 1.41%. That's already one of the lowest edges in the casino. But when you back it with free odds, the blended house edge across your total money at risk drops significantly.

Here is how the math works with the 3-4-5x odds format as an example:

• With 1x odds: combined house edge drops to roughly 0.85%
• With 2x odds: drops to approximately 0.61%
• With 3-4-5x odds: drops to around 0.37%
• With 10x odds: drops to approximately 0.18%
• With 100x odds: approaches virtually zero overall

These figures assume you always take full odds. If you take partial odds or skip the free odds bet entirely, your blended edge rises back toward the base 1.41% of the Pass Line alone. The implication is clear: always take the maximum free odds the table allows, provided you're comfortable with the total amount of money in play.

Don't Pass and Don't Come: The Other Side of Free Odds

The free odds concept also applies to the Don't Pass bet, which is essentially the opposite of the Pass Line. Don't Pass bettors want the shooter to seven-out before hitting the Point. The house edge on the Don't Pass line is 1.36%, marginally lower than Pass Line.

When you lay odds behind a Don't Pass bet, you are laying true odds — meaning you are the favourite in the bet, so you must risk more than you stand to win. For example, if the Point is 4, you would need to risk $40 in lay odds to win $20, because the true probability favours the Don't Pass bettor at that stage. This is mathematically equivalent to the Pass Line free odds in terms of edge — there is none — but it requires a larger amount of cash on the table to generate a given profit.

Similarly, Come bets and Don't Come bets work like Pass and Don't Pass, but they are placed after a Point has been established and apply to the next roll as though it were a fresh come-out. You can take or lay odds on Come and Don't Come bets in exactly the same way, with the same zero-edge mathematics.

The Practical Reality at the Table

If you've never played craps in person, the idea of placing a bet behind your existing bet can be confusing. Here's the practical mechanics:

1. Place your chips on the Pass Line before the come-out roll.
2. Wait for a Point to be established (the dealer will move the puck to the Point number).
3. Place additional chips directly behind your Pass Line bet — in the space between the Pass Line and the bottom rail of the table. There's no marked box for this; it's an unwritten convention.
4. The dealer knows what this means. You don't need to announce it, though you can say "odds" if you want to be clear.
5. If the shooter makes the Point, your Pass Line bet pays even money and your free odds bet pays at the true odds for that Point number.

It's worth noting that free odds bets can be removed or reduced at any time, unlike the Pass Line bet itself, which is locked in once the Point is established. This gives you flexibility if your session isn't going well and you want to reduce your exposure.

Bankroll Considerations and Responsible Play

The temptation when you discover free odds is to immediately seek out tables with the highest multipliers available. The logic makes mathematical sense: more money on a zero-edge bet means a lower blended house advantage. But there is a practical caveat. Higher odds multipliers mean more total money at risk on any single Pass Line decision.

If you buy in with a modest session bankroll, taking maximum 10x odds on a $10 Pass Line bet means $110 in total action on a single roll. A series of seven-outs in quick succession can devastate a limited bankroll before the mathematics of lower house edge have any meaningful chance to play out. The theoretical edge reduction only provides its full benefit over a large number of decisions.

A sensible approach is to choose an odds multiple that keeps your total per-decision risk in a range you're comfortable with across at least 30 to 50 come-out decisions. That gives the lower house edge meaningful time to assert itself, and it ensures you remain at the table long enough to actually enjoy the game. Never bet money you cannot afford to lose, and set a firm session loss limit before you begin.

Why Free Odds Matter Beyond the Numbers

Understanding free odds does more than improve your theoretical return. It changes how you think about the entire craps table. Once you grasp the concept of true odds and the zero-edge bet, you start viewing every other wager on the layout through a more critical lens. The proposition bets in the centre of the table — the hardways, the any-seven bet, the field in certain configurations — suddenly look very different when you know the house edge on those can exceed 10% or even 16%.

Craps is a game with a wide spectrum of bet quality, from the excellent Pass Line and free odds structure at one end to the near-predatory proposition bets at the other. Knowing where free odds sit on that spectrum, and why, transforms you from a player who simply hopes for luck into one who understands the mathematical architecture of the game. That knowledge doesn't guarantee winning sessions — nothing does — but it ensures that when variance does go in your favour, you've been extracting the best possible value from every dollar you risked along the way.
