The Boxcars Bet in Craps: Odds, Payout, and Why They Call It Midnight
Jake WilfredTwo sixes staring up at you from the felt. That’s boxcars. It’s the highest number you can roll on two dice, and it’s one of the rarest, showing up just once every 36 throws on average. The boxcars bet in craps is a one-roll proposition bet that the next throw will be a 12.
Hit it, and the casino pays you 30:1. Miss it (which you will 97.22% of the time), and your chips vanish. It’s the identical twin of the snake eyes bet on the opposite end of the number line, carrying the same 13.89% house edge and the same long-shot profile.
This guide covers the full math behind boxcars, how to place the bet, what it really costs you, and where the colorful nickname comes from.
- Boxcars is a one-roll bet that the shooter will roll a 12 (6+6), paying 30:1
- There’s exactly 1 way to roll a 12 out of 36 possible dice combinations, giving you a 2.78% win probability
- The true odds are 35:1, but the casino pays only 30:1, creating a 13.89% house edge
- Boxcars is also called “Midnight” (12 o’clock) and “Cornrows” at some tables
- If you want to cover both extremes (2 and 12), the Hi-Lo bet at 11.11% house edge is the cheaper option
What Is the Boxcars Bet?
The boxcars bet is a single-roll wager that the very next throw of the dice will total 12. There’s only one dice combination that produces a 12: both dice showing 6. That’s it. One combination out of 36 possible outcomes.
The bet sits in the center section of the craps table layout, grouped with other proposition bets. You’ll see it labeled as “12” or “Boxcars” depending on the casino. Toss your chips to the stickman and call “boxcars” or “twelve.” The stickman places them in the corresponding section.
One roll decides everything. If the dice show 6-6, you win. Any other combination, you lose.
Boxcars goes by several nicknames across different casinos and regions. “Midnight” refers to 12 o’clock on a clock face. “Cornrows” comes from the pattern of six dots on each die, which some players think resembles rows of corn. You might also hear dealers call it “double six” or simply “twelve.” All refer to the same bet with the same odds. For a full glossary, check our craps terms guide.
Why Is It Called Boxcars?
The name “boxcars” comes from the visual. Two sixes side by side, each showing a rectangular pattern of dots (two columns of three), look like a pair of railroad boxcars viewed from the end. It’s one of those pieces of craps history that stuck because it’s vivid. Once you see it, you can’t unsee it.
Boxcars Odds, Payout, and House Edge
The math on boxcars is straightforward and, frankly, not kind to the player.
True odds: 35 to 1. There are 35 ways to lose and 1 way to win. Casino payout: 30 to 1. House edge: 13.89%.
The casino withholds 5 units from the true-odds payout. A fair bet on boxcars would pay $35 for every $1 wagered. You get $30 instead. That missing $5 across 36 theoretical rolls is the casino’s profit margin.
You bet $1 on boxcars for 36 consecutive rolls. Statistically, you’d win once, collecting $30. You’d lose 35 times, losing $35. Net result: down $5 on $36 in total action. That’s 13.89% of your money gone. Compare that to a pass line bet, where $36 in action costs you about $0.51 in expected loss. The boxcars bet costs you nearly 10 times more per dollar wagered.
Some tables display the boxcars payout as “31 for 1” instead of “30 to 1.” These are identical. “For” includes your original bet in the total return; “to” shows only the profit portion. If you see “31 for 1,” don’t mistake it for a better deal. It’s the same 30:1 net payout and the same 13.89% house edge. This “for” versus “to” language appears across all proposition bets and confuses plenty of experienced players.
The 12 in Craps: More Than Just Boxcars
The number 12 plays several roles on the craps table beyond the boxcars bet. Understanding how it interacts with other wagers helps you see the full picture.
On the come-out roll, a 12 is “craps.” If you have a pass line bet, you lose. If you have a don’t pass bet, it’s a push (the “bar 12” rule). The 12 also wins on an any craps bet (7:1 payout), counts toward the “Tall” portion of the All Tall Small bet, and is one of the four numbers covered by the horn bet.
The 12 also wins on the field bet, typically paying 2:1 (or 3:1 at some tables). If you’re looking for action on the 12 with a lower house edge, the field bet is a far better vehicle. At a triple-12 table, the field’s house edge is just 2.78%, compared to boxcars’ 13.89%.
If you like the 12 but hate the 13.89% house edge, consider the field bet instead. The field covers seven numbers (including the 12) and pays 2:1 or 3:1 on the 12, with a much lower house edge of 5.56% (or 2.78% at triple-12 tables). You won’t get the 30:1 boxcars thrill, but you’ll lose a lot less money per hour while still getting paid when double sixes land.
Boxcars vs. Other Proposition Bets
How does boxcars stack up against its neighbors in the center of the table?
| Bet | Wins On | Payout | Win Probability | House Edge |
|---|---|---|---|---|
| Boxcars (12) | 6-6 | 30:1 | 2.78% | 13.89% |
| Snake Eyes (2) | 1-1 | 30:1 | 2.78% | 13.89% |
| Hi-Lo (2 or 12) | 1-1 or 6-6 | 15:1 | 5.56% | 11.11% |
| Any Craps (2, 3, or 12) | 2, 3, or 12 | 7:1 | 11.11% | 11.11% |
| Yo (11) | 5-6 or 6-5 | 15:1 | 5.56% | 11.11% |
| Any Seven | Any 7 | 4:1 | 16.67% | 16.67% |
Boxcars and snake eyes are mirror images. Same odds, same payout, same house edge. They’re the two extremes of the dice, each with just one way to appear. The Hi-Lo bet covers both of them in a single wager at a lower house edge (11.11%), making it the better option if you want action on both ends.
The only proposition bet worse than boxcars by house edge is Any Seven at 16.67%. Everything else in the center of the table carries an 11.11% to 12.50% edge, which is bad but less bad than boxcars’ 13.89%.
How to Place a Boxcars Bet
Boxcars lives in the center of the table, which means you don’t handle it yourself.
Toss your chips toward the center of the felt before the next roll. Call out “boxcars” or “twelve” or “midnight” clearly so the stickman knows your bet. The stickman places your chips in the “12” section of the proposition layout, positioned to indicate which player the bet belongs to.
The bet resolves on the very next roll. If double sixes appear, the stickman announces “twelve, boxcars” and the dealer pays you 30:1. Any other result, your chips are swept.
You toss a $5 chip to the stickman and call “boxcars.” The shooter throws two dice. They land 6-6. The dealer counts out $150 ($5 x 30) and places it in front of you, along with your original $5. Total return: $155. If the shooter had rolled anything other than 6-6, you’d be down $5. That’s the entire bet: one roll, one outcome, 2.78% chance of a big payoff.
You can place a boxcars bet on any roll, whether it’s a come-out roll, mid-point, or anywhere in between. There are no timing restrictions. For proper table communication, check out our craps etiquette guide.
Is the Boxcars Bet Worth Making?
Let’s be honest about what you’re buying.
The boxcars bet is a 2.78% shot at a 30:1 payout, wrapped in a 13.89% house edge. It’s not a smart bet by any mathematical standard. For every $100 you wager on boxcars over time, you can expect to lose $13.89. That same $100 on the pass line would cost you $1.41. On free odds, it would cost you $0.
- 30:1 payout turns a small bet into a meaningful win when it hits
- Simple and immediate: one roll, instant resolution, zero complexity
- At $1 per bet, the absolute cost is low enough to be trivial
- The rarity of the 12 makes winning feel genuinely special
- 13.89% house edge is one of the highest on the standard craps table
- You lose 97.22% of the time, which means long stretches between wins
- True odds are 35:1 but you only get paid 30:1, a 5-unit shortfall
- Money on boxcars is money not working on the pass line with odds (0% house edge)
- Betting it every roll can silently burn through your bankroll
The boxcars bet belongs in the same category as all center-table props: fun money, not strategy money. A $1 boxcars bet here and there adds a little spice to your session. Making it a habit on every roll adds a lot of cost. Your core bankroll should live on the pass line with odds, come bets, or place bets on the 6 and 8.
Better Ways to Get Action on the 12
If the 12 calls to you, there are cheaper ways to answer.
The field bet covers the 12 (along with 2, 3, 4, 9, 10, and 11) at a house edge of 5.56% or 2.78% at triple-12 tables. You won’t get 30:1 when the 12 hits, but you’ll get 2:1 or 3:1 while also winning on six other numbers. The field bet gives you far more chances to win per roll at a fraction of the boxcars’ house edge.
The Hi-Lo bet covers both the 12 and the 2 for 15:1 at an 11.11% house edge. If you’d normally bet boxcars and snake eyes separately ($2 total at 13.89% each), a single $1 Hi-Lo gives you the same coverage for less total cost.
The any craps bet covers the 2, 3, and 12 at 7:1 with an 11.11% house edge. It wins three times as often as boxcars, though the payout is much smaller. If you want action on craps numbers specifically, it’s the more efficient container.
None of these alternatives are “good” bets compared to the pass line or free odds. But they’re all less expensive than boxcars per dollar wagered. If you’re going to bet on the 12 regardless, at least choose the vehicle that costs you the least. The field bet at a triple-12 table (2.78% edge) is the standout option. See all the numbers in our craps payout chart.
The Boxcars Bet: A 30:1 Thrill With a 13.89% Price Tag
Boxcars is craps at its most extreme. One combination out of 36. A 2.78% chance. A 30:1 payout that turns a $1 chip into $31 in your hand. It’s the kind of bet that generates the loudest single-roll cheers at the table, and the kind that quietly drains your stack if you make it a habit.
Know the math. Respect the edge. Keep boxcars as the occasional $1 side flyer during a hot session, not a pillar of your approach. Your real money belongs on the best craps bets where the house edge is measured in fractions of a percent, not double digits.

Boxcars is the craps term for rolling a 12 (two sixes). The name comes from the visual resemblance of two side-by-side sixes to a pair of railroad boxcars.

For don’t pass bettors, the 12 is a push (neither win nor loss) because the table “bars” the 12 to prevent the don’t pass from being a player-advantage bet. If you have a boxcars side bet active, you’d also win the 30:1 payout regardless of what happens to the line bets.
