The best bubble craps strategy is Pass Line with maximum Free Odds - the same as live craps. What changes are the bets to avoid on a bubble machine because the payouts are worse. Place 6/8, Field 12, and Hardways all take a payout cut on most bubble machines. Knowing exactly which bets got worse - and by how much - is the entire strategic edge at the electronic table.
Practice the strategy first
Crapsee's bubble craps simulator uses the same 6-for-5 Place payouts, 2-to-1 Field 12, and reduced Hardways that real machines use. You can test every strategy on this page before you sit down at a live terminal.
The 60-second version
- Pass Line + Max Odds. This is your core play. Full stop.
- Skip Place 6 and Place 8. The 6-for-5 payout makes them worse here.
- Avoid Field 12. 2-to-1 instead of 3-to-1 doubles the edge.
- No Hardways. Already bad bets, made worse by bubble payouts.
- Pace yourself. 60-120 rounds per hour - set tighter win/loss limits than you would at a live table.
Why bubble craps needs its own strategy
Standard craps strategy advice - "Place 6 and 8 for the best odds" - is built around live table payouts. Bubble craps machines shave the payouts on three categories of bets to offset the cost of running the hardware. If you apply live-craps strategy to a bubble machine unchanged, you will be playing three bets at roughly double their intended house edge without realizing it.
The core rules of craps are identical between formats. The point system, come-out roll, Pass/Don't Pass mechanics - all unchanged. If you need a refresher on the rules, see the bubble craps guide. This page assumes you know the basics and focuses entirely on where the math changes and what to do about it.
The three categories where bubble machines reduce payouts versus a live table are:
- Place 6 and Place 8 (6-for-5 instead of 7-to-6)
- Field 12 (2-to-1 instead of 3-to-1)
- Hardways (one point lower on Hard 4/6/8/10)
Everything else - Pass Line, Don't Pass, Come, Don't Come, Free Odds - pays identically to a live table.
The payouts that change: live vs bubble
The table below shows every meaningful payout difference between a standard live craps table and the industry-standard bubble machine configuration. House edge figures are mathematically derived.
| Bet | Live payout | Live edge | Bubble payout | Bubble edge | Verdict |
|---|---|---|---|---|---|
| Pass Line | 1 to 1 | 1.41% | 1 to 1 | 1.41% | Same - play it |
| Don't Pass | 1 to 1 | 1.36% | 1 to 1 | 1.36% | Same - play it |
| Free Odds | True odds | 0% | True odds | 0% | Same - max it |
| Place 6 / 8 | 7 to 6 | 1.52% | 6 for 5 | ~2.78% | Worse - skip it |
| Place 5 / 9 | 7 to 5 | 4.00% | 7 to 5 | 4.00% | Same (already poor) |
| Place 4 / 10 | 9 to 5 | 6.67% | 9 to 5 | 6.67% | Same (already bad) |
| Field 12 | 3 to 1 | 2.78% | 2 to 1 | 5.56% | Worse - avoid |
| Hardway 6 / 8 | 9 to 1 | 9.09% | 8 to 1 | ~11% | Worse - avoid |
| Hardway 4 / 10 | 7 to 1 | 11.11% | 6 to 1 | ~14% | Worse - avoid |
| Any Seven | 4 to 1 | 16.67% | 4 to 1 | 16.67% | Same (never play it) |
Paytables vary from machine to machine. Some casinos run tighter configurations than shown here. Always check the paytable printed on the machine before you sit down - on most terminals it is accessible from the help or info button.
Pass Line + Max Odds: the foundation
The Pass Line bet has a 1.41% house edge. Free Odds behind the Pass Line have a 0% house edge - the only zero-edge bet in craps. Combining them lowers your overall edge based on how much you take in odds relative to your flat bet:
| Odds multiple | Combined edge (Pass Line + Odds) |
|---|---|
| No odds (flat only) | 1.41% |
| 1x Odds | 0.85% |
| 2x Odds | 0.61% |
| 3x Odds | 0.47% |
| 5x Odds | 0.33% |
| 10x Odds | 0.18% |
Bubble machines are often more generous with odds multiples than live tables. Many bubble terminals allow 5x or 10x odds. If your live casino limits odds to 2x but its bubble machine offers 5x, the bubble machine is actually better for an odds-focused strategy - the lower payout on Place 6/8 is more than offset by the ability to press large odds bets.
Don't Pass with Lay Odds
Don't Pass starts at 1.36% and Lay Odds bring the combined edge to about 0.27% at 5x - the single lowest edge available on a bubble machine. If the math is all you care about, Don't Pass is the right call. In practice, betting against the point on a solo machine feels counterintuitive to most players. Both options are far superior to any other bet on the machine.
Adding Come bets for number coverage
Once a point is established, you can extend coverage by placing Come bets with Full Odds behind each. Two Come bets plus your Pass Line bet gives you action on three numbers at a combined edge under 0.5%. This is the bubble-machine equivalent of the 3 Point Molly strategy used at live tables. The approach is mathematically sound - just be aware the faster pace means your bankroll cycles through these positions 3x as quickly as at a live table.
Why you should skip Place 6/8 on bubble specifically
Place 6 and Place 8 are the go-to non-odds bets at a live craps table for a reason: 7-to-6 payout, 1.52% house edge. That guidance does not carry over to bubble craps.
The 6-for-5 math explained
"7 to 6" and "6 for 5" look similar but produce meaningfully different outcomes. Here is the arithmetic side by side on a $30 Place 6 bet:
| Format | Payout stated | What you receive | Your stake returned? | Net profit |
|---|---|---|---|---|
| Live (7 to 6) | $35 won on $30 | $35 profit + $30 stake | Yes, separately | $35 |
| Bubble (6 for 5) | $36 returned on $30 | $36 total including stake | Included in the 6 | $6 |
On a $5 Place 6 bet: live pays $5.83 profit (7-to-6 on $5 = $5.83); bubble pays $1 profit (6-for-5 on $5 = $6 total, $5 back, $1 net). The bubble machine's house edge on Place 6/8 rises from 1.52% to approximately 2.78% - nearly double.
2.78% is not catastrophic. But when your alternative is Free Odds behind the Pass Line at 0% edge, there is no reason to take a 2.78% edge bet instead. Every dollar you put into Place 6/8 on a bubble machine would be better placed as additional Odds behind your Pass Line.
Exception: If a specific machine pays 7-to-6 on Place 6/8 (rare but it exists at some higher-end casinos), the situation flips - take the Place bets, they are now live-table quality. Check the paytable on your specific terminal.
Field 12 on bubble: 5.56% edge
The Field bet pays even money on 3, 4, 9, 10, and 11. On 2 it pays 2-to-1. On 12 it pays 3-to-1 at a live table - and 2-to-1 on most bubble machines.
That single number - the 12 - carries the entire weight of the Field bet's math. With a 3-to-1 payout on 12, the live Field edge is 2.78%. With a 2-to-1 payout on 12, the bubble Field edge doubles to 5.56%.
5.56% is the same edge as a pair of sixes in American roulette. It is not a proposition-bet disaster, but it is firmly in "avoid" territory for any player following a strategy. The Field is a one-roll bet, which means at 90 rounds per hour you are placing 90 Field bets per hour. At $5 per bet with a 5.56% edge, your expected hourly cost is about $25. At a live table (2.78% edge, 30 rolls per hour), the same bet costs about $4 per hour. The combination of worse payout and faster pace makes the Field bet far more damaging at a bubble machine than the raw edge number suggests.
Hardways on bubble
Hardway bets are already the weakest commonly placed bets at a live craps table. On bubble machines they are worse.
| Bet | Live payout | Live edge | Bubble payout | Bubble edge |
|---|---|---|---|---|
| Hard 6 / Hard 8 | 9 to 1 | 9.09% | 8 to 1 | ~11% |
| Hard 4 / Hard 10 | 7 to 1 | 11.11% | 6 to 1 | ~14% |
Hard 4 and Hard 10 at 6-to-1 are approaching the edge of Any Seven (16.67%). These bets exist to provide entertainment value, not expected value. On a bubble machine where rounds resolve every 15 seconds, entertainment bets compound their cost rapidly. Skip Hardways entirely.
Check your specific machine. Some higher-end bubble terminals do pay standard Hardway rates. If Hard 6/8 shows 9-to-1 on the paytable, those are live-table rates and the guidance reverts to standard live-craps advice (still not great, but not actively worse).
Bets that are identical on bubble vs live
Not everything changes. The following bets pay identically on bubble and live tables, which means all standard craps advice applies to them unchanged:
- Pass Line (1.41% edge). Same on every craps format in existence. Your first dollar always goes here.
- Don't Pass (1.36% edge). Same. Slightly better than Pass Line but psychologically harder for most players.
- Come and Don't Come. Identical to Pass/Don't Pass respectively. Take full Odds behind Come bets as you would at a live table.
- Free Odds (0% edge). True odds on every format. Max this whenever available. The bubble machine's often-generous odds multiples (5x, 10x) are a genuine advantage.
- Place 4 and Place 10 (6.67% edge). Same on bubble and live. Still a poor bet either way - the unchanged edge here is not an endorsement.
- Place 5 and Place 9 (4.00% edge). Same on bubble and live. Acceptable for entertainment but worse than Odds bets.
- Any Seven (16.67% edge). Same on every format. Never play this.
For a full breakdown of every bet's edge on a live table, see the craps odds chart. The figures there apply directly to the "same" column of bubble craps payouts.
Bankroll management for the faster pace
Bubble craps runs 60 to 120 rounds per hour. A live craps table runs 20 to 40. At 90 rounds per hour on bubble versus 30 rounds per hour on live, you face three times the number of decisions in the same clock time. Your bankroll is exposed to the house edge at triple speed.
This does not change the optimal bet, but it changes how you should think about session limits. Standard bankroll advice for live craps does not account for the pace multiplier.
Adjust your win target and stop-loss
If you normally set a 30-unit stop-loss and a 20-unit win target at a live table, tighten those for bubble craps. A 20-unit stop-loss and a 15-unit win target produce similar real-time session volatility to your live-table limits. The math does not change - variance compounds at the same rate per decision - but decisions arrive faster, so limits protect you from the same downswing unfolding in 20 minutes instead of 60.
Stadium minimums may be higher
Stadium-format bubble craps - the large shared machine with 8-16 players in tiered seating - sometimes carries a $5 or $10 minimum instead of the $1 minimum common on single-player machines. The strategic advice is identical between formats. The higher minimum means your bankroll in dollar terms needs to scale proportionally.
Bubble-specific bankroll math
These figures are based on Pass Line + 5x Odds (0.33% combined edge) at 90 rounds per hour. They represent theoretical expected loss per hour, not guaranteed outcomes - variance can swing either direction in short sessions.
| Flat bet size | Odds bet (5x) | Total action/round | Expected loss/hour | Live equivalent loss/hour |
|---|---|---|---|---|
| $1 | $5 | $6 avg | ~$0.18 | ~$0.04 |
| $5 | $25 | $30 avg | ~$0.89 | ~$0.21 |
| $10 | $50 | $60 avg | ~$1.78 | ~$0.42 |
| $25 | $125 | $150 avg | ~$4.46 | ~$1.05 |
The "live equivalent" column assumes 30 rounds per hour at the same combined 0.33% edge. The bubble machine's faster pace multiplies the expected loss by roughly 3x even when the edge is identical. At higher flat-bet sizes the difference becomes material - a $25-flat player at a bubble machine loses theoretically what a $75-flat player loses at a live table, per hour.
The practical takeaway: match your bankroll to the pace, not just the bet size. Bring the same number of units to a bubble session as you would to a live session, but expect them to cycle about 3x faster. Plan your session time accordingly.

Frequently asked questions
What is the best bubble craps strategy?
Pass Line with maximum Free Odds. The Pass Line has a 1.41% edge and Free Odds have 0% edge. At a 5x odds machine your combined edge drops to about 0.33%. This is the same optimal play as live craps - what changes on bubble machines is which bets to avoid, not the core approach.
Are Place bets bad on bubble craps?
Place 6 and Place 8 are meaningfully worse on bubble craps than at a live table. Live craps pays 7-to-6 on Place 6/8 for a 1.52% house edge. Bubble machines typically pay 6-for-5, which raises the edge to about 2.78%. That is nearly double. Skip Place 6/8 on bubble machines and put that money into Free Odds behind your Pass Line instead.
Why is Field 12 different on bubble craps?
Most bubble craps machines pay 2-to-1 on the Field 12, while a live craps table pays 3-to-1. This single payout change raises the Field bet house edge from 2.78% (live) to 5.56% (bubble). That makes the Field bet twice as costly on a bubble machine, which is why it should be avoided as part of any sound strategy.
Is Pass Line still good on bubble craps?
Yes. Pass Line pays 1-to-1 on both bubble and live craps. The 1.41% house edge is identical on both formats. Free Odds behind the Pass Line also pay true odds (0% edge) on bubble machines, same as live. The Pass Line + Max Odds combination is the foundation of bubble craps strategy for exactly this reason.
What is 6 for 5 vs 7 to 6?
"7 to 6" means you win 7 units on a 6-unit bet - your $6 stake stays, and you collect $7 profit. "6 for 5" means you receive 6 units total on a 5-unit bet - you get $6 back including your original $5, so your net profit is only $1. On a $30 Place 6: live (7-to-6) returns $35 profit; bubble (6-for-5) returns $6 profit. The 6-for-5 format roughly doubles the house edge from 1.52% to 2.78%.
How fast is bubble craps?
Bubble craps runs 60 to 120 rounds per hour compared to 20 to 40 at a live craps table - roughly 3 times the pace. Your bankroll is exposed to the house edge approximately 3 times as fast. A session budget that lasts two hours at a live table may last only 40 minutes on a bubble machine at the same bet sizes.
Can you win at bubble craps?
You can win in the short term. Every bet on a bubble machine has a positive house edge, so the machine wins over thousands of rounds. Short sessions regularly end profitable with Pass Line and Max Odds, which keeps the combined edge below 0.5%. Setting a win target and a stop-loss and leaving when either triggers is the most practical way to walk away up more often than not.
Do Hardways pay less on bubble craps?
Often yes. Many bubble machines pay Hard 6 and Hard 8 at 8-to-1 instead of the standard 9-to-1, and Hard 4 and Hard 10 at 6-to-1 instead of 7-to-1. Hard 6/8 at 8-to-1 carry roughly an 11% house edge (up from 9.09%). Hard 4/10 at 6-to-1 carry roughly a 14% edge (up from 11.11%). These are already among the worst bets in craps - on bubble machines they are worse still.
