Craps Variants at a Glance
Standard table craps, crapless craps and bubble craps share the familiar dice-game setting but differ in how the game is presented and, in crapless craps, in the rules. Standard craps and bubble craps use the same rules and bets, so their house edges are equal when the same wagers are made. Standard craps with a line bet and odds has the lowest overall cost compared with crapless craps. Gambling is risky: treat these games as entertainment, and remember that every version has a built-in house edge. Players must meet the legal gambling age, which is 21 at most US commercial casinos and 18 at some tribal casinos; check local law before playing.
Crapless Craps
Crapless craps changes the pass-line sequence at the come-out roll, while keeping the familiar two-dice totals from 2 through 12. The key change is that a 7 wins for the pass line and every other total becomes a point, so no come-out total immediately loses. That rule affects which numbers can put a pass-line bet at risk and changes its house edge. The sections below detail the come-out results, true-odds payouts and pass-line cost.
How the come-out roll changes
On a crapless come-out roll, 7 wins for the pass line; every other total from 2 through 12 becomes the point. Standard craps instead resolves some totals immediately and uses only six numbers as points.
| Total | Standard craps | Crapless craps |
|---|---|---|
| 2 | Pass line loses | Becomes the point |
| 3 | Pass line loses | Becomes the point |
| 4 | Becomes the point | Becomes the point |
| 5 | Becomes the point | Becomes the point |
| 6 | Becomes the point | Becomes the point |
| 7 | Pass line wins | Pass line wins |
| 8 | Becomes the point | Becomes the point |
| 9 | Becomes the point | Becomes the point |
| 10 | Becomes the point | Becomes the point |
| 11 | Pass line wins | Becomes the point |
| 12 | Push; pass-line bet is returned | Becomes the point |
Once a point is set, the pass-line bet stays unresolved until that point rolls again or a 7 appears. In crapless play, that point can be any total except 7, including 2, 3, 11 and 12; in standard play, those four totals do not enter the point phase.
The practical cost is that totals which would lose or push on a standard come-out roll instead keep the pass-line wager in action as points. That creates more ways for a bet to remain exposed to a later 7, so the altered come-out rule is not simply a way to avoid an immediate loss.
Odds on 2, 3, 11 and 12
Crapless Craps odds for the added points use true-odds payouts, which reflect each point’s chance of appearing before a 7. The standard point odds remain available for 4, 5, 6, 8, 9 and 10.
- A point of 2 or 12 pays 6:1 on a true-odds wager, matching the one dice combination for each total.
- A point of 3 or 11 pays 3:1 on a true-odds wager, since each total can be made with two combinations.
- A point of 4 or 10 pays the standard true-odds rate of 2:1 after either total has been established.
- A point of 5 or 9 pays the standard true-odds rate of 3:2, reflecting four combinations for either total.
- A point of 6 or 8 pays the standard true-odds rate of 6:5, the lowest true-odds payout among the point numbers.
These figures describe the odds wager, not the original pass-line payout. Don’t-side rules vary by game, particularly for the added point numbers, so check the specific game’s don’t rules before placing a don’t bet.
House edge compared with standard craps
The pass-line house edge is 5.38% in crapless craps, compared with 1.41% in standard craps. The difference is 3.97 percentage points per pass-line wager, making the crapless pass line substantially more expensive over repeated bets. These figures apply to the pass-line bet; they are not payout rates on an individual roll.
The cause is the treatment of the come-out totals. In standard craps, 2 and 3 lose for the pass line, while 12 returns the wager; in crapless play, all three become points. After one of those points is established, the pass-line bet must wait for that same total or a 7. Because a 7 can arrive first, the added points create extra ways for the pass-line wager to lose rather than ending the bet immediately on the come-out.
True-odds payouts on a separate odds wager do not erase the higher cost of the underlying pass-line bet. For a lower pass-line house edge, standard craps is the less costly choice; choose crapless only if having every non-7 total become a point is worth that higher edge to you.
Bubble Craps
Bubble craps uses physical dice, but the game is organized around a transparent dome and individual betting terminals rather than a shared live table. The format keeps the standard craps wagers and their mathematical terms while changing how players place bets and follow each roll. Automated operation can shorten the time between rolls, and minimum bets are generally lower than at a live table. The main distinction is the pace and style of interaction, not the underlying cost of a given wager.
How the electronic table works
Bubble craps is not a video simulation of dice: a pair of physical dice is shaken inside a transparent dome. Depending on the machine, a player starts the shake with a button, or the mechanism runs automatically after betting closes. The dice settle in view of the players, and the system registers the result and displays it on the terminals.
Each player uses an individual terminal to choose wagers and enter bet amounts. The screen shows the current stage of the hand, such as the come-out roll or a point number, and indicates which bets are available. Players make selections on their own screens instead of placing chips on a shared felt layout. The machine then records the wagers for the next roll and updates the displayed outcome after the dice stop.
Staffing differs from a live table because there is no crew needed to handle each roll and manage chip movement across a full layout. A casino attendant may monitor several terminals, assist with machine operation, or address a payout issue; the exact arrangement depends on the venue. This setup makes the game feel more individual than table craps, even though everyone at the bank follows the same dice result. For players comparing craps game formats, the key practical change is the terminal-based interaction around a physical roll.
What stays the same
When the bubble game uses standard craps rules, its core wagering terms match those of a conventional table:
- Bet menu: Familiar wagers such as Pass Line, Don’t Pass, Come, Don’t Come, place bets, and proposition bets follow the same underlying craps rules.
- Odds bets: Taking or laying odds behind a line or come wager uses the same point-dependent payouts as at a standard table.
- Payouts: A winning wager pays according to its listed standard craps payoff; using a terminal does not change the payout for that bet.
- House edges: Each wager retains its standard mathematical house edge when the bubble game applies the same rules and pay table.
House edge differs from one bet to another, but the electronic format does not itself alter those percentages. The interaction changes; the underlying bet terms do not.
Speed and minimum bets
With no stickman calling the dice and no boxman overseeing the table, bubble craps removes much of the live table’s chip handling and verbal procedure. The machine records wagers, resolves the result, and prepares the next round, so rolls are generally faster. Actual pace still varies with how quickly players at the terminals make their selections and with the machine’s operating cycle.
Minimum bets are generally lower than those at a live craps table, which can make the format accessible to players who want to try a few wagers without joining a higher-limit layout. The lower entry point does not change the payout or house edge attached to a particular bet. It changes how little a player can stake on an individual wager, not the percentage cost built into that wager.
This pace suits players who prefer a compact, self-directed session, want time to read terminal prompts, or would rather avoid making decisions in front of a live table crew. It can also suit experienced players who want quicker rounds and do not need the social exchange of a staffed table. A useful Bubble Craps strategy is to set a session budget and choose wagers before play: faster rounds can mean more decisions in the same amount of time, while the house edge per bet remains tied to the wager and rules.
Which Version to Choose
The right format depends on whether you value a familiar ruleset, a quicker electronic session, or lower expected losses. Standard craps provides the clearest reference point because its pass-line decisions are used at most conventional tables. Crapless craps changes the treatment of come-out numbers, while bubble craps can reproduce standard rules or use a machine-specific variation. Compare the rules and pace before choosing, then keep the expected cost of your wagers in view.
Learning the rules
For learning, compare the decisions a player makes and the pass-line house edge, rather than assuming every electronic game uses identical rules. These figures describe common standard-rule play; check a machine’s displayed paytable because Bubble Craps variations can change the available bets or their returns.
| Format | Key rules | Typical pace | Pass-line house edge |
|---|---|---|---|
| Standard table craps | On the come-out roll, 7 or 11 wins; 2, 3 or 12 loses. A 4, 5, 6, 8, 9 or 10 establishes the point. | Live, dealer-led rolls; pauses depend on the shooter and table activity. | 1.41%; odds wagers have no house edge. |
| Crapless craps | Come-out 2, 3, 11 and 12 can become points instead of resolving immediately; a 7 still loses the pass-line bet. | Live, dealer-led rolls; broadly comparable to a conventional table. | About 5.38% on the pass line. |
| Bubble craps | Often follows standard pass-line rules, but the machine’s displayed rules determine the exact bets and payouts. | Electronic roll cycle; automated prompts reduce dealer-related pauses. | Often 1.41% under standard rules; confirm the machine’s paytable. |
Standard craps is the strongest starting point for learning because its common pass-line outcomes also provide the baseline for understanding other formats. Practise identifying the come-out result and point before adding come and place bets; those two decisions explain much of the table’s basic flow. Choose bubble craps when you prefer an electronic interface or want a game that does not depend on a live dealer’s pace. Crapless craps is better approached after standard rules are familiar, since its additional point numbers change the meaning of come-out rolls. The practical recommendation is to learn on standard craps, use bubble craps for a more automated session, and select crapless only when you specifically want its expanded point structure.
Comparing cost per hour
Standard craps with line bets and odds has the lowest cost. The pass-line bet carries a 1.41% house edge under standard rules, while a properly offered odds wager has no house edge; adding odds can lower the combined edge on the total amount at risk. Your actual expected loss still depends on the size of each wager and how much you bet over the session, so a low-edge game is not cost-free.
At the same house edge and average wager, a faster game costs more per hour because more bets are made per unit time. For example, if two sessions use the same bet size and edge but one completes more betting decisions in an hour, its expected loss for that hour rises in proportion to the additional action. Bubble craps may move through rolls with fewer dealer-related pauses, so set a time or spending limit rather than treating a quick cycle as a reason to increase the stake.
Crapless craps costs more per bet owing to its higher pass-line house edge: about 5.38%, compared with 1.41% for the standard pass line. With equal pass-line wagers, that edge makes the expected loss per decision higher before speed or session length is considered. The size of any difference in total hourly cost then depends on the table’s pace, your average wager and the number of decisions you make.
For the lowest expected cost, choose standard craps, keep wagers modest and use odds only when they fit your budget. If speed matters more than a live-table feel, choose bubble craps but account for its faster turnover. Choose crapless craps for its distinct rules, not as a lower-cost alternative.
