If you’ve spent any time around a craps table, either in a live venue or scrolling through an online lobby, you’ve probably noticed the buy bet tucked under the wagers marked on the layout. It’s one of those wagers that looks identical to a place bet at a glance, but the maths behind the commission changes the picture once you start tracking real sessions. In Australia, most regulated online platforms don’t stream craps directly, so punters who want to play tend to compare international rooms carefully before committing. Below is a walkthrough of how a buy bet actually behaves on the felt, how the ongoing promotions shape the long game, and what to weigh before you put a dollar down.
How a Buy Bet Actually Pays
A buy bet is a wager on a point number – 4, 5, 6, 8, 9, or 10 – paying true odds rather than the slightly trimmed place-bet payouts. The trade-off is a commission, usually 5%, charged on the original stake. In practical terms, a $20 buy on the 4 wins $40 plus your stake back, but the dealer takes $1 upfront, so the net payout lands at $39. On the 5 or 9, the same $20 wins $28 net of the dollar commission.
For Australian players used to fractional returns, the difference feels small on a single hit, but across an evening it can swing a session. Place bets on 6 and 8 pay 7:6, which is the standard sore point for craps grinders, so a buy on those numbers flattens the vig into a clean 1.414:1. A buy on 4 or 10 still gets chewed up by that 5% commission because the payout is 2:1, meaning you actually need the number to hit more than once just to break even on the vig. That single quirk is why seasoned players mostly buy 6 and 8 and place everything else.
Walking Through a Buy Bet at the Tables
Placing the Bet and Declaring the Intent
In a live setting, you don’t quietly slide a chip onto the layout the way you would with a pass line wager. You put your chips in the come area and tell the dealer, plain as day, “Buy the 6” or “Buy the 8.” The dealer will move your chips to the point box and mark them with a buy button, so the boxperson knows to collect the vig. Forget to say “buy” and your chips default to a place bet, which is a small but common mistake worth drilling into muscle memory before you travel to an international room or join a live craps stream.
Paying the Commission Upfront
Most rooms take the 5% vig the moment the bet is placed, even though some European floors wait and collect only on a win. If you’re betting in AUD, $20 buys a $1 vig and $40 gets a $2 vig. Online live-dealer studios tend to follow the American upfront model because it’s easier to automate. Either way, the commission is non-refundable, so a bought number that loses the point still costs you the vig you already paid. Hedging your bets across multiple points can cushion that sting, because a loss on one number might be offset by a hit on another, but the spread itself doesn’t reduce the per-bet vig cost.
Tracking Wins, Losses, and the Long Run
A practical way to keep the maths honest is to log each buy bet in a small notebook or a notes app, including the number, stake, vig, and result. After an hour, you can see whether the 4 and 10 buy bets have earned their commission back or whether the 6 and 8 are doing the heavy lifting. I’ve seen Wollongong clubbies run informal sessions like this during their afternoon arvos, and the players who track outcomes walk away with a much clearer sense of which numbers actually carry their bankroll.
Promotions, Loyalty Value, and Who a Buy Bet Suits
The welcome bonus is the bait, but the recurring promos decide whether a craps room is worth sticking with. Strong platforms layer reload bonuses, weekly cashback on net losses, and a tiered VIP club where points convert to bonus credits or tournament entries. Buy bet players benefit disproportionately from loss-based cashback, because the upfront vig inflates turnover and the cashback percentage applies to that higher figure. Look for rooms that run weekly craps or live-dealer tournaments with prize pools of $5,000 or more, plus a loyalty scheme that pays out 1 point per $10 wagered and redeems at roughly 100 points for $1 in bonus funds.
On the brain science side, research into near-miss effects shows that a bought 6 that lands on a 7-out feels disproportionately painful, because the win-related regions still light up even when the result is a loss. That bias is exactly why buy-bet strategy is mostly a discipline game rather than a chase game.
A buy bet fits players who already understand vig maths, prefer a flatter return on the 6 and 8, and want their loyalty value to compound over months. If you’re a casual punter who bets once a month and chases the welcome offer, a straightforward place bet on 6 and 8 keeps the bookkeeping simpler. Serious grinders, on the other hand, get more mileage out of a buy bet because every commission dollar comes back through structured cashback and VIP tiers.
“Buy bets on 6 and 8 are usually the only ones that mathematically justify the vig for most recreational players,” notes Thomas Harris, Strategy Director at Yarra Gaming Lab. “On 4 and 10, the commission eats most of the true-odds edge.”
