craps when to buy vs place
craps when to buy vs place — this exact phrase captures a pivotal strategic crossroads every serious shooter faces at the craps table. It’s not about luck. It’s about math, timing, and understanding how the casino structures its advantage differently across seemingly similar wagers. Whether you’re rolling dice in Las Vegas, Atlantic City, or playing online from New Jersey, knowing when to buy versus when to place can shave critical percentage points off the house edge—and that directly impacts your bankroll longevity.
The Hidden Math Behind "Buy" and "Place"
Most casual players treat “buy” and “place” bets as interchangeable. They’re not. Both target the same numbers—4, 5, 6, 8, 9, 10—but their payout structures and commission mechanics diverge sharply.
A Place bet pays fixed odds:
- 7:6 on 6 and 8
- 7:5 on 5 and 9
- 9:5 on 4 and 10
These payouts are less than true odds (which would be 6:5, 3:2, and 2:1 respectively), embedding a built-in house edge.
A Buy bet, by contrast, pays true odds—but only after you pay a 5% commission (vig) to the house. Traditionally, this vig is charged upfront on the bet amount, though some casinos now apply it only on wins—a crucial distinction affecting expected value.
Here’s where intuition fails most players: Buy bets aren’t automatically better just because they pay true odds. The vig often negates that benefit unless you’re betting on specific numbers or meet minimum thresholds.
What Others Won't Tell You
Casino marketing materials won’t highlight these pitfalls—but seasoned dice veterans know them cold:
The $20 Trap on 4 and 10
Many players assume buying the 4 or 10 is always superior due to the high house edge on placing them (6.67%). True odds are 2:1, so a $20 Place bet wins $36. A $20 Buy bet wins $40—but you pay a $1 vig (5% of $20). Net win: $39. That’s better... unless the casino charges vig on all buys regardless of outcome. Then you lose $1 even if you lose the bet. Worse: some venues enforce a minimum $20 buy on 4/10, but allow $5 Place bets. If you only want to risk $10? Placing might be your only option—and far less efficient.
Vig Timing Changes Everything
In Nevada and many online platforms licensed by the New Jersey Division of Gaming Enforcement (NJDGE), vig is collected only on winning Buy bets for 4 and 10. This slashes the effective house edge to 1.67%—making Buy vastly superior to Place (6.67%). But for 5 and 9? Even with win-only vig, Buy carries a 2.00% edge vs. Place’s 4.00%. Still better—but the gap narrows.
However, for 6 and 8, Place bets dominate. Their house edge is just 1.52%, while Buy bets—even with win-only vig—sit at 2.27%. Buying the 6 or 8 is almost always a mistake.
Table Minimums Mask True Costs
A $10 table might let you Place the 6 for $6 (to get paid in whole dollars). But to Buy the 4, you may need $20 minimum. That’s over triple your exposure for a marginal edge improvement. Risk-adjusted returns matter more than raw percentages.
Online Quirks: Auto-Vig and Rounding
Some NJ-licensed online casinos auto-deduct vig from winnings and round down. A $25 Buy on 10 wins $50 true odds—but after $1.25 vig, you get $48.75, which may round to $48. That hidden rounding cost isn’t disclosed in help files.
Strategic Decision Matrix: Buy or Place?
Use this table to decide instantly based on number, vig policy, and bet size. All figures assume USD and standard U.S. casino rules.
| Point Number | Place Bet House Edge | Buy Bet House Edge (Vig on Win) | Buy Bet House Edge (Vig Upfront) | Recommended Action (Min Bet ≥ $20) | Notes |
|---|---|---|---|---|---|
| 4 or 10 | 6.67% | 1.67% | 4.76% | Buy (if vig on win) | Avoid if vig upfront and < $20 |
| 5 or 9 | 4.00% | 2.00% | 3.77% | Buy (if vig on win) | Place acceptable for small bets |
| 6 or 8 | 1.52% | 2.27% | 2.78% | Place | Never buy these numbers |
| All (Low Budget) | — | — | — | Place 6/8; Avoid 4/10 | Preserve bankroll |
| High Roller | — | — | — | Buy 4/10/5/9; Place 6/8 | Maximize edge where it counts |
Pro Tip: Always ask the dealer: “Is the vig on buys taken on wins only?” In Atlantic City and most legal U.S. online casinos, the answer for 4/10 is yes—but never assume.
Real-World Scenarios: $100 Bankroll Test
Let’s simulate two players over 100 rolls targeting point numbers only:
- Player A always Places: $12 on 6/8, $10 on 5/9, $10 on 4/10
- Player B Buys 4/10 ($20 each, vig on win), Buys 5/9 ($15 each), Places 6/8 ($12)
