Craps Buy Bet Explained: Payouts, House Edge and How Locals Use Them
If you’ve stood near a craps table in a Sydney saloon and watched chips glide across the felt, you’ve probably noticed players placing extra wagers on the point numbers – 4, 5, 6, 8, 9 or 10 – and asking the dealer for a “buy” instead of a standard place bet. The craps buy bet explained properly comes down to one trade-off: you pay a five percent commission up front, but you get paid at true odds when your number lands. Everyone chasing the best return on a point number is essentially working this same deal.
How a Buy Bet Actually Works at the Table
A buy bet is a wager on a point number that pays 1:1 minus the 5% vig. Hit a 6 or an 8 the hard way and true odds are 6:5, which works out to a $30 win on a $25 buy at full commission. The same maths applies to 4, 5, 9 and 10 with their own true-odd payouts.
From my time around Aruze Gaming Australia product planning, I’ve sat with operators in Pyrmont who would ask product managers to dial the commission exactly like that – not because 4% or 6% is unheard of, but because the 5% vig has become the expected industry default. The bet is “on” for the next roll only; you tell the dealer to take it down between rolls if you’ve changed your mind. Most Sydney venues require a minimum buy of $20 – some of the smaller suburban clubs $25 – and the commission is paid only when you win, never on the stake itself.
The vig sits on top of an already thin house edge, which is why smart players only buy the 4 and 10. Numbers 5, 6, 8 and 9 carry a place-bet equivalent that’s essentially the same effective edge, so paying the commission costs you for no extra return. Australia’s recent compliance fines – millions of dollars against venues caught misrepresenting payouts or rigour around side wagers – have also tightened signage and T&Cs, so you’ll now see buy-bet rules printed on the rail rather than buried in a brochure.

Walking Through a Buy Bet in Play
The rhythm in a busy gaming room is the same wherever you watch. You get your chips, the stickman swings the dice, and the point gets established. That’s where a buy bet has its moment.
Placing the Wager and Tracking the Commission
“Play for fun craps online” is one of the easier ways to test the mechanic before risking anything at the tables, and the rules translate cleanly from screen to felt. Verbal the bet to the dealer and they’ll slide a “buy” marker onto your number on the layout; the dealer mirrors your chip on the dealer’s side as a record of the commission owing. There’s no separate “buy bet” printed zone – it’s the same point-number box used for place bets, which is where a lot of first-time players get tripped up.
Commission only changes hands when you win, and dealers don’t usually ask – they work it out themselves, paying the reduced amount and pushing the vig to the house tray. From my own observation across multiple Australian venues, the most common friction point isn’t the maths – it’s the player who forgets to call it down before the next come-out roll and assumes the bet will sit there indefinitely. It won’t.
What This Means for Everyday Australian Players
If you’re playing for entertainment and your bankroll is small, a buy bet on the 4 or 10 makes a clean case: roughly 4.76% house edge, true-odds payouts, no hidden rake on the stake. If you’re playing for longer sessions and want lower-variance action, the 6 and 8 buy at around 2.27% – the best effective return on the layout. Buying 5 or 9 doesn’t really pay you back for the commission, and a standard place bet on those numbers does the same job without the vig.
A few practical notes before you commit chips. Confirm the venue’s minimum on a buy before you bet – $20 or $25 are common in Sydney clubs, and the difference is meaningful if you’re only buying 4 and 10. Ask the boxperson to confirm the commission is paid only on a win. Read the rail signage; after recent fines against venues caught sloppy on side-wager disclosures, almost every licensed room in NSW now spells it out in centimetres. And remember the bet is a one-roll continuation – every “on” buy is live until the come-out resets it.

You can also work through the same idea in a low-pressure setting by trying play for fun craps online with Greater Clarity-style sessions that mirror what you’ll see on a real felt.
Verdict: a buy bet is worth using when the maths favours you – namely on 4, 5, 9 and 10 in their true-odds payouts – and worth skipping on 5 and 9, where the commission simply doesn’t earn its keep. In a regulated Australian venue with $20 minimums and proper signage, treating the buy as a deliberate true-odds play rather than a default place substitute is the cleanest way to use it.
