Walk into any casino from the Wynn in Vegas to a riverboat in Missouri, and you’ll hear the craps table before you see it. It’s loud. It’s chaotic. People are screaming, high-fiving, and throwing plastic bones across a felt sea of confusing numbers. But here is the thing: most of those people are bleeding money because they don’t actually understand craps betting odds. They’re betting on "the yo" or "boxcars" because it feels exciting, while the house is basically printing money off their enthusiasm.
Craps is a weird game. It’s the only place in the casino where you can find a bet with a 0% house edge, yet it also hosts some of the biggest "sucker bets" on the floor. If you want to survive more than twenty minutes at the table, you have to stop looking at the shiny numbers and start looking at the math.
The Foundation: Why 7 Is the King of the Table
Everything in craps starts with the number seven. If you don't respect the seven, you’re done. There are 36 possible combinations with two six-sided dice. Mathematically, the seven is the most likely outcome because there are six ways to roll it: 1-6, 6-1, 2-5, 5-2, 3-4, and 4-3.
Basically, you have a 1 in 6 chance of seeing a seven on any given toss.
Compare that to the 2 (snake eyes) or the 12 (boxcars). There is only one way to hit those. One. This disparity is why the payouts look so tempting for the hard ways or the "any craps" bets. The casino isn't being generous; they’re pricing in a massive margin. When you understand that the 7 is the gravitational center of the game, the rest of the craps betting odds start to make sense. You aren't playing against the shooter; you are playing against the probability of that 7 showing up before your point does.
Pass Line and Don’t Pass: The Smart Money
Most people start with the Pass Line. It’s the "good guy" bet. You’re rooting for the shooter. If they roll a 7 or 11 on the come-out, you win. If they roll a 2, 3, or 12, you lose. Any other number becomes the "point."

The house edge on a Pass Line bet is about 1.41%. That is actually one of the best deals in the building. It’s way better than standard slots and miles ahead of double-zero roulette.
But if you want to be the person the table hates (but the person with the slightly better math), you bet the Don't Pass. You’re "wrong-way" betting. You’re rooting for the shooter to crap out. The house edge here drops to 1.36%. Is it a huge difference? No. But over ten thousand rolls, that tiny sliver of a percentage is the difference between a steak dinner and a cheap buffet. Honestly, most people can't handle the social pressure of cheering when everyone else loses, so they stick to the Pass Line. That's fine. Just know you're paying a 0.05% "social tax."
The "Free" Odds: The Only Fair Bet in Vegas
Here is the secret. Once a point is established, you can "lay odds" or "take odds" behind your main bet. This is the holy grail of craps betting odds.
The casino pays this out at true mathematical parity. There is zero house edge. None. If the point is a 4 or 10, the true odds are 2-to-1 because there are three ways to roll those numbers and six ways to roll a 7. The casino will pay you exactly 2-to-1.
You won't find this mentioned on the table felt. Why would they? They don't make money on it. They actually want to hide it. Most players forget to do it, or they don't put enough down. You should always put as much as you can afford into the Odds bet because it dilutes the overall house edge of your total money on the table. If you're playing at a "3x 4x 5x" table, you can really bring that effective house edge down to under 1%. That’s as close to a fair fight as you’re ever going to get in Nevada.
The Sucker Bets You Need to Ignore
Every time I see someone throw a chip on "Hard 8" or "The Horn," I cringe a little bit. I get it. The payouts look huge. 30-to-1 for a 2 or 12? Sounds like a dream.
But the math is a nightmare.
The house edge on a "Yo-leven" (betting the 11 will show up on the next roll) is a staggering 11.11%. That is highway robbery. You might as well just hand your money to the dealer and go get a drink. The "Any Craps" bet is even worse, often hovering around an 11% house edge. These are "one-roll" bets. They are designed to drain your chip stack while you're waiting for something interesting to happen.
Hardways—betting a number will come up as a pair (like two 4s for a Hard 8)—are slightly better but still hover between 9% and 12% depending on the house rules. They’re fun. They make the game exciting. They are also the fastest way to lose your bankroll. If you’re serious about craps betting odds, you have to treat the middle of the table like it’s radioactive. Don't touch it.
Place Bets vs. Come Bets
This is where the nuance of an expert comes in. A lot of players love Place bets. You tell the dealer, "Place the 6 and 8." It’s fast. You don’t have to wait for a come-out roll.
The 6 and 8 are the best place bets because they are the most likely numbers to hit after the 7. They pay 7-to-6. This means you should always bet in multiples of $6. If you bet $5, the casino only pays you $5 (even money), and they keep that extra dollar. That’s a massive mistake. Always bet $6, $12, $18.
The house edge on a Place 6 or 8 is 1.52%.
Now, compare that to a Come bet. A Come bet is basically a Pass Line bet made in the middle of a round. It allows you to take "Odds" just like the Pass Line. Because you can take those 0% house edge odds, the Come bet is mathematically superior to the Place bet.
However, Come bets are "contract" bets. Once you put them out there, you can't take them back. Place bets can be taken down whenever you want. If you have a bad feeling or you’ve reached your win limit, you can just yell "Turn my bets off!" and the dealer pulls them back. You pay a little bit for that flexibility. Is it worth the jump from a 1.41% edge to a 1.52% edge? For most casual players, yeah, probably.
The Math of the "Iron Cross" and Other Systems
You’ve probably heard of the Iron Cross. It’s a famous system where you bet the Field, and Place the 5, 6, and 8. The idea is that you win on every single number except the 7.
It feels like you’re winning all the time. The dealer is constantly pushing chips your way. But here is the catch: you are betting a lot of money to win a little bit. When that 7 eventually shows up—and it will, it’s the king of the table—it wipes out four different bets at once.
The Field bet itself is usually a trap. Most casinos pay double on the 2 and 12, which gives the house an edge of about 2.7%. Some generous places pay triple on the 12, which brings the edge down to 1.21%. If you aren't at a "Triple 12" table, the Field is a bad bet. Period. The Iron Cross is just a fancy way to dress up a mediocre strategy with a high turnover of chips. It’s great for getting "comps" because the casino sees a lot of action, but it’s not a winning long-term strategy for craps betting odds.
Understanding the Table Environment
The odds aren't just on the felt. They’re in the rules posted on the little plaque near the dealer.
- Check the Odds Limit: A "100x Odds" table is a gold mine. It means you can bet $5 on the Pass Line and $500 on the Odds. This effectively kills the house edge.
- Look at the Field: Does it pay 3x on the 12? If not, stay away.
- The "Vig" on Buy Bets: Sometimes you can "Buy" the 4 or 10. You pay a 5% commission (the vig) to get true 2-to-1 odds. At some casinos, you only pay the vig on a win. At others, you pay it upfront. Only play where you pay on the win. It makes a huge difference in your theoretical return.
Real World Application: Your Next Session
Stop betting with your heart. The dice don't have a memory. They don't care that a 7 hasn't shown up in twenty rolls. The craps betting odds remain exactly the same on every single toss.
If you want to play like a pro, follow this flow:
- Wait for a new shooter.
- Put the table minimum on the Pass Line.
- If a point is established (4, 5, 6, 8, 9, 10), back that bet with the maximum Odds you can afford.
- If you want more action, place a Come bet and back it with Odds too.
- Ignore the "Hardways" and "Center Bets" no matter how much the stickman yells about them. They are literally paid to entice you into those high-edge bets.
- If you’re betting the 6 or 8, always do it in multiples of $6.
The goal isn't to get rich on one roll. It's to stay at the table long enough to catch a "hot hand" where the shooter avoids the 7 for thirty minutes. By sticking to low-edge bets, you minimize the "drain" on your bankroll, giving you the stamina to be there when the big streak finally happens.
Before you head to the cage, take a look at the "Don't Pass" side. If you can handle being the villain, it really is the best math on the board. Most people can't. But the math doesn't care about your feelings. It only cares about the 36 combinations of the dice. Focus on the 6-and-8, maximize your odds, and stay away from the "sucker" bets in the middle. That's how you actually beat the house at its own game.
Go to the table with a set bankroll. Divide it by 50. That should be your "unit" for the Pass Line. If you have $500, bet $10. This gives you enough "swing" room to handle the natural variance of the dice without going bust in the first ten minutes. Consistency is the only thing that beats the house in the long run.
