Quick Answer
There is no single “best” online casino game to win, as all casino games are designed to give the house a statistical edge over time. However, for Australian players, the game with the lowest house edge—and therefore the best mathematical chance of winning—is blackjack, when played with optimal strategy. Other strong contenders include baccarat (specifically the banker bet), craps (pass/don’t pass line bets), and video poker (with high return-to-player tables). It is critical to note that Australian law, specifically the Interactive Gambling Act 1997 (IGA), heavily restricts online casino offerings, making it illegal for operators based in Australia to provide “real-money” online casino games to Australian residents. Most reputable options for Australian players come from offshore-licensed casinos, which carry their own risks.
Understanding House Edge and RTP
To identify the best game to win, you must first understand two key metrics: House Edge and Return to Player (RTP). The house edge is the mathematical advantage the casino holds over players over the long term. RTP is the theoretical percentage of wagered money a game will return to players over countless rounds. For example, a game with a 99% RTP has a 1% house edge. The lower the house edge, the better your chances of winning in the short term and minimizing losses over the long term.
Blackjack: The Best Odds with Skill
Blackjack consistently offers the lowest house edge in most land-based and online casinos, often below 0.5% when using basic strategy. This means for every $100 wagered, you statistically lose only $0.50. However, this depends entirely on the game’s rules (e.g., number of decks, whether the dealer stands on soft 17, doubling options). Australian players should look for single-deck or 6-deck blackjack with favourable rules. Be aware that many online blackjack variants use continuous shuffling machines (CSMs), which slightly increase the house edge. While skill can reduce the edge, blackjack still involves variance, and short-term losing streaks are common.
Baccarat: Simple and Low House Edge
Baccarat is a pure game of chance with no skill element. The banker bet has a house edge of approximately 1.06%, while the player bet sits at about 1.24%. The tie bet, with a house edge over 14%, should be avoided. For Australian players, baccarat is widely available at offshore casinos and is favoured for its simplicity and low volatility. However, the IGA prohibits Australian-based operators from offering it, so you must use offshore sites, which may not provide the same consumer protections as domestic venues.
Craps: Pass Line and Don’t Pass Line
Craps offers some of the best odds in the casino, particularly on the pass line (house edge ~1.41%) and don’t pass line (~1.36%). These bets are straightforward and have low house edges. However, craps is less common at online casinos due to its complexity and slower gameplay. Australian players may find limited options, and the game is often simulated with random number generators (RNGs) rather than physical dice, which can affect trustworthiness.
Video Poker: High RTP with Optimal Play
Video poker combines elements of slots and poker, offering some of the highest RTPs in online gambling—up to 99.5% or more on games like Jacks or Better with a full pay table. The key is to find machines with a “9/6” pay table (9 coins for a full house, 6 for a flush). With perfect strategy, the house edge can be as low as 0.5%. However, many online video poker variants have lower pay tables, reducing RTP to 97-98%. Australian players should scrutinise pay tables carefully, as offshore casinos often adjust them to increase the house edge.
Slots: High Risk, High Reward (But Low Odds)
Slots are the most popular online casino games, but they generally have the worst odds for players. The average RTP for online slots ranges from 92% to 97%, meaning a house edge of 3% to 8%. Progressive jackpot slots can have RTPs as low as 85% because a portion of each bet funds the jackpot. While slots can produce massive wins, the mathematical probability of a significant payout is extremely low. For Australian players, slots are widely available offshore, but the IGA makes them illegal when offered by Australian-licensed operators. Always verify the RTP of any slot game before playing.
Australian Laws and the IGA 1997
The Interactive Gambling Act 1997 (IGA) is the primary federal law governing online gambling in Australia. It makes it illegal for operators based in Australia to offer “real-money” online casino games (like blackjack, roulette, slots) to Australian residents. However, the IGA does not explicitly prohibit Australian players from accessing these games on offshore-licensed casinos (e.g., those licensed in Malta, Curacao, or the UK). This creates a grey area: while playing offshore is not a criminal offence for the player, it carries significant risks, including lack of legal recourse if disputes arise, potential issues with withdrawals, and exposure to unregulated or rogue operators. The Australian Communications and Media Authority (ACMA) actively blocks illegal offshore websites, but many remain accessible. As such, the “best” game to win is only relevant if you choose a licensed and reputable offshore casino—something this article does not recommend.
Games to Avoid for Australian Players
- Keno: House edge can exceed 25%, making it one of the worst bets.
- Wheel of Fortune-style games: Typically have house edges over 10%.
- Side bets in blackjack or baccarat: Often have house edges of 5-15%.
- Progressive jackpot slots: While tempting, low RTPs and high variance make them poor for consistent winning.
Key Takeaways for Australian Players
- Blackjack with basic strategy offers the best mathematical chance to win, with house edges below 0.5%.
- Baccarat (banker bet) and craps (pass/don’t pass) are excellent low-edge alternatives.
- Video poker (9/6 Jacks or Better) can rival blackjack in RTP if you play optimally.
- Avoid slots, keno, and side bets unless you are playing purely for entertainment, as their house edges are significantly higher.
- The IGA 1997 makes it illegal for Australian-based operators to offer online casino games, so any real-money play must occur at offshore casinos—which carry higher risk and no local consumer protection.
- No game guarantees wins in the short term. Always set a budget, play responsibly, and treat gambling as entertainment, not a way to make money.
- Verify game RTPs and casino licenses before depositing. Look for casinos regulated by reputable authorities (e.g., Malta Gaming Authority, UK Gambling Commission) if you choose to play offshore.
In summary, the best game to win is the one with the lowest house edge that you can play correctly. For most Australian players, this means blackjack or baccarat, but only if accessed through a safe, licensed offshore casino—and always with the understanding that the house always wins over the long term.
