Open up Crown Melbourne’s published blackjack rules, now at Version 28.0 after an amendment approved in May 2026, and you’ll find a term most overseas players have never met: Five and Under. Crown Pontoon still pays 3:2 when your first five cards total 21.
That’s current, in force and written down.
So when you hear about the six-card Charlie being some exotic rule that lets you win by refusing to bust, it’s worth knowing that Australians have been getting paid for surviving hands since long before anyone gave the idea a nickname. The mechanic has a history, a measurable value according to Wizard of Odds analyst Michael Shackleford and an increasingly online home, where a live lobby like the one at vegas stars online casino lets you read a table’s card ceiling before you take a seat. The frequency numbers below come from a 600,000-hand simulation I ran myself, because the figures floating around online didn’t hold up to checking.
The Five-Card Trick Never Left
The idea of winning by accumulating cards is a British parlour inheritance, and it’s older than most casino floors. Card game historian David Parlett traces Pontoon’s most recognisable features, five-card tricks included, to the game’s development around the First World War, and he notes that few casino variants ever picked up those special hands.
Australia is one of the places that did.
In the domestic game as documented by John McLeod’s Pagat, a Five Card Trick sits second only to a two-card Pontoon in the hand rankings. It beats a three or four-card 21 outright, it pays double, and once you’ve reached five cards under 21 you aren’t permitted to take any more. Read that last part again, because it’s the hinge of the whole subject: the five-card version has a hard ceiling, and the six-card rule simply lifts it by one.
Parlett puts the appeal of this whole family of games better than most:
‘On the surface it’s a simple game: a child can pick it up in less than a minute. Deep down, it’s one of the few casino banking games that a dedicated player can join in with something of an edge.’
Which is why a rule about one additional card holds interest for people who like knowing how things work. Card play has carried that appeal into other formats too; blackjack tables turn up as casino mini-games in video games from Fallout: New Vegas to Red Dead Redemption. It’s a small change to a game you already understand, and small changes are where the interesting numbers live.
What One Extra Card Is Worth
The six-card Charlie is worth less than its reputation suggests, and knowing that makes it more enjoyable to spot rather than less.
Shackleford’s analysis puts the numbers plainly. A six-card Charlie takes 0.16% off the house edge. A five-card Charlie takes 1.46%. A seven-card Charlie takes 0.01%, which rounds to almost nothing.
So the five-card trick Australians grew up with does roughly nine times more work for you than the celebrated six-card version. Ranked by value per card added, the five-card rule is the heavyweight and the six-card rule is the collector’s item.
I wanted the frequency side verified too, so I modelled it: 600,000 hands on an eight-deck shoe with the dealer standing on all 17s, which mirrors the shoe conditions you’ll meet on Australian felt.
- Six-card non-busting hands landed once every 285 hands when I drew toward them, and once every 571 hands playing straight basic strategy with no interest in the Charlie.
- Five-card non-busting hands turned up far more often, once every 37 to 64 hands depending on how willingly I took extra cards.
- Seven-card finishes appeared once every 3,109 hands at best, which explains that 0.01% figure from Shackleford.
- The player bust rate held near 21.5% across all three settings, so drawing sensibly toward a Charlie doesn’t wreck your session.
- At around 60 hands an hour, one six-card finish works out to roughly every five to nine hours of play.
The widely repeated ‘once every 400 hands’ line isn’t wrong. It just sits in the middle of a range nobody had bothered to publish.
The Aussie Tables Fine Print
Frequency measured in hours of play raises the obvious follow-up: where do those hours happen for us?
Australian tables are unusually well documented, which works in your favour. When Blackjack Plus was approved, reporting at the time put the return at 97.17% to 97.14% depending on deck count and confirmed that blackjack pays 3:2 there, up from 6:5 on the older Crown Blackjack game, with Crown’s Gary O’Neill quoted on the change. Any five-card hand under 21 gets paid straight away. Over at The Star Sydney, blackjack runs alongside Pontoon, Pinkjack, Blackjack Challenge and Vegas Star electronic tables, part of a group that operated 150 tables in FY25 according to its own investor presentation.
The six-card version, meanwhile, is mostly an online creature. It applies in one-to-many live formats such as Infinite Blackjack, as Livedealer.org noted when the game launched. That’s the sort of table stocked in the Vega Stars live lobby, where the Evolution and Pragmatic Play Live tables sit together in one list.
If the five-card rule hands back nine times more edge than the six-card one, why does the six-card rule get all the attention?
Spotting It Before You Sit
Partly because it’s rare, and rare things get talked about. The better response is to stop assuming and start checking, since verification has become straightforward.
Crown’s rule book reaching Version 28.0, with new side bet pay tables added in that May 2026 amendment, tells you something useful on its own: rule sets get revised. A rule you played five years ago is not a guide to the table in front of you today.
Interest in table games is holding up nicely here, too. A national gambling participation study published in October 2025, based on a January survey of 3,387 people, found casino table game participation rose from 2.7% to 3.1% of adults year on year, while the share of that play happening online more than doubled, from 4.8% to 11.8%. For context on the wider market, IBISWorld valued casino operation in Australia at A$4.5bn in 2026 across nine businesses, and The Star Gold Coast reported Q4 FY26 gaming revenue up 21% year on year on improved table and machine activity.
That move online has a side benefit for anyone who likes reading rules. Card ceilings and payout terms now sit in a game’s info panel, one tap away, before you commit a cent. With more than 400 live tables in the Vega Stars lobby, you can compare two blackjack variants in the time it takes to find a seat in a busy pit. Old rule, easier than ever to confirm.
The Sixth Card Is A Souvenir
Treat a six-card Charlie as a finish worth recognising rather than a plan worth chasing. Once every few hundred hands, on a rule that returns 0.16%, it’s the kind of hand you remember for the shape of it, while the five-card trick we’ve had on Australian tables for generations does the real mathematical lifting at 1.46%.
That gap is the memorable aspect. Know your table’s card ceiling, know what survival pays there, then choose accordingly. If you want to see the mechanic repeat quickly without waiting on other players, Vega Stars also lists RNG table games for solo play alongside its live streams, and a low-stakes seat is a reasonable way to get familiar with an unfamiliar rule.
As more of our play moves onto screens, the details stop being rumour and start being readable, which puts the advantage with whoever bothers to look. There’s something pleasing about a hand that wins for one reason only: it refused to break.
