Quick answer: Star Blackjack at The Star Sydney uses 6 or 8 decks, pays 3:2 and the dealer hits soft 17 (the rule says stand on hard 17 or soft 18). Blackjack Challenge pays more on blackjacks, but tied hands lose, so its house edge is 2.53%. The lowest house edge on the floor belongs to Pontoon at about 0.42%.

We went through The Star's current game rules (Star Blackjack, version 15, dated 15 August 2025, and the Blackjack Challenge rules order signed on the same day) and checked them against the published maths. Sydney has a reputation among players as one of the tougher rooms in the country. Is that fair? For the standard game, mostly yes. For Pontoon, no.

Star Blackjack: the core rules

When Wizard of Odds visited in 2008, the standard game used 8 decks, one split only, stand on soft 17 and the BB+1 hole card rule, for a house edge of 0.59%. Hitting soft 17 adds about 0.22%. So if the other rules are unchanged, today's game sits at roughly 0.8% (our estimate, not an official figure).

What a dealer blackjack takes at The Star

Wizard of Odds recorded the BB+1 rule in Sydney: the dealer takes any busted bets plus one more unit from what is left. Some players and books call a similar rule OBBO, so the names get mixed up. Before you play, read the doubling and splitting clauses in the current rules.

Blackjack Challenge: generous payouts, costly ties

Wizard of Odds first spotted Blackjack Challenge at The Star in December 2014. The Star publishes the current Blackjack Challenge game rules (official PDF). The rules look friendly at first glance:

And the catch:

A blackjack that pays 2 to 1 sounds generous. So why is the house edge 2.53%, about three times the standard game? Because ties happen far more often than blackjacks, and every one of them now goes to the house. As one Whirlpool poster put it years ago, the bigger blackjack payout only softens the blow a little.

Pontoon: the best bet on the floor

This surprises most people. Australian Pontoon takes the 10s out of the deck, yet Wizard of Odds puts the Sydney version at 0.42%, about a third lower than conventional blackjack there. The main reason: a player 21 always wins, even against a dealer blackjack. Our Pontoon vs blackjack guide explains the rules and the house edge in every city.

NSW rules every player should know

Minimum bets and electronic tables

The Star does not publish a fixed minimum list. The last detailed player report we found (2019) described A$40 to A$50 minimums for a hit-soft-17 game, A$100 for a stand-on-soft-17 game and shuffling machines across the main floor. Another visitor that year mentioned A$20 Blackjack Challenge and A$5 video blackjack machines. Treat these as old reports. We track newer ones in blackjack minimum bets in Australia.

In my experience, the cheapest seat is not always the cheapest game. At the same stake, a Blackjack Challenge table costs about six times more per hour than a Pontoon table.
