What is a Lay Bet in Craps?

A lay bet in Craps sees players bet against the shooter, with the aim of 7 points landing first.

This goes against accepted practice. Usually, everyone’s rooting for the shooter.

While the table cheers for points, you’re backing the 7 to crash the party first. It’s bold, it’s contrarian, and it’s massively misunderstood.

In this guide, we’ll break down what a lay bet is in Craps, how it works, what the odds and payouts really look like, and when it’s worth making the move. We’ll demystify the math, call out common misconceptions, show you how to calculate your returns like a pro, and put lay bets into the bigger Craps strategy picture.

A lay bet is a simple wager: you’re betting that a specific number (called the “point”) won’t roll before a 7 does. So if the point is 4 and you place a lay bet, you’re betting the next 7 shows up before the 4 does again.

Think of it as the evil twin of a place bet. With place bets, you’re hoping the number hits before a 7. With lay bets, it’s the opposite. But you can only place a lay bet after the point is established on the come-out roll.

This isn’t some sneaky side bet either — it’s a full-fledged, odds-driven move that smart players keep in their back pocket.

It flips the game on its head — and gives you a new way to play when the table’s feeling ice-cold.

A lay bet in Craps sees players wager that a 7 will show up and end the shooter’s run.

Here’s an example of how it works.

Say the shooter rolls a 5. That becomes the point. You swoop in and lay the 5, meaning you’re betting on a 7 showing up before another 5.

You can lay the following numbers: 4, 5, 6, 8, 9, and 10.

Here’s how it plays out:

• 7 hits first? You win.
• Point hits first? You lose.

That’s the entire deal. You’re the one betting against the flow — the person silently rooting for the dice to end the run.

You’re not betting on failure, you’re betting on math. And when you’ve seen enough shooters go ice-cold after a hot streak, you’ll start to appreciate just how effective that bet can be.

What many players don’t realize is just how common the 7 is in Craps. It’s not superstition — it’s statistics. With six different dice combinations leading to a 7, it’s more likely to show up than any other number on the felt. That’s why you’re laying more than you stand to win: the odds are on your side.

And unlike place bets or pass line bets that lock you into the rhythm of the shooter, lay bets are reactive. You wait. You watch. You strike.

Here’s the trade-off: the odds are in your favor, but you’ve got to risk more than you stand to win. That’s because 7 is the most common number in Craps — and the math reflects it.

Here’s a quick snapshot:

If you want to win $30 laying the 4, you’ll need to bet $60, plus a $1.50 commission in most casinos.

Important: Commission is typically 5% on the amount you could win, and some casinos take it up front, while others only collect if your bet wins. Always ask.

This commission is known as the “vig” — short for vigorish. It’s a small price to pay for one of the lowest house edge bets on the felt. But it’s not optional, and it adds up over time. Make sure you include it when calculating your exposure.

Also note that some casinos offer “no vig” lay bets on 6 and 8 — though they usually bake the cost into slightly less favorable payout odds. That’s still a fair trade if you don’t want to sweat over nickels on every resolution.

You should absolutely use a Craps lay bet calculator, as it can be very useful in helping you decide what your bet should be. This can be especially useful if you’re a newcomer to the game.

You’re not alone if the payout math makes your brain twitch. That’s what a lay bet calculator is for. Just punch in how much you want to win, or you’re prepared to risk. Pick the number, and it’ll tell you what the bet should be.

Example:

• Want to win $30 laying the 4? Bet $60 + $1.50 commission.
• Laying $30 on the 6? Expect to win $25, minus $1.25 commission.

Let’s break down the math: If you lay $60 to win $30 (minus $1.50 commission), your net win is $28.50. You’ve got a 2-in-3 shot to win that, and a 1-in-3 chance to lose the full $60. Do the math, and your expected return averages out to about -1, which is a 1.67% house edge.

Small edge. Low risk. Big potential over time.

Calculators don’t just do the math — they give you clarity. Whether you’re sizing a hedge, comparing different lay bets, or just keeping things tidy at a busy table, these tools help you play smarter.

Pro tip: Some online tools let you input different commission structures, which is especially handy if you’re bouncing between casinos that apply vig differently.

You’ll want to know the true value of your bet before you stack your chips.

✅ Smart times to lay it down:

• When the point is 4 or 10 — those are the hardest to hit
• When you’re hedging another bet
• When the table’s gone cold and shooters can’t hold a hand
• When the dice have rolled several numbers without a 7 — and you feel the correction coming
• When you want to mix it up and take a contrarian position without fully switching to don’t pass

🚫 Maybe sit it out when:

• The table’s red hot and the shooter’s in the zone
• You don’t feel confident sizing the bet with commission factored in
• You’re only chasing house edge stats without considering volatility
• You’re at a full table and don’t want to kill the vibe — social pressure is real
• You’re short-stacked and can’t afford to risk 2x or 3x your target win

Smart lay bettors are like card counters — they know the odds, they watch the table, and they make surgical plays when it counts.

From a math perspective? Absolutely.

Lay bets give you strong odds, low house edge, and full control over when you place (and remove) them.

Compared to don’t pass or don’t come, lay bets offer more flexibility. You pick the number, place the bet anytime, and pull it when the moment’s passed.

And unlike flat don’t pass bets that lock you into the full ride, lay bets let you cherry-pick numbers — perfect for players who like to control their own destiny.

Used wisely, lay bets are a great tool in your Craps arsenal — especially when the dice are feeling streaky.
