What online casino game pays out the most?

Quick Answer

There is no single online casino game that universally “pays out the most” because payout rates depend on game type, provider, and the casino’s Return to Player (RTP) settings. However, based on statistical RTP percentages, the highest-paying online casino games are typically video poker variants (e.g., Jacks or Better with 99.54% RTP) and select online blackjack games (with optimal strategy, up to 99.8% RTP). Among slots, the highest RTP titles (e.g., some NetEnt or Microgaming games) can reach 98–99%, but these are rare and often excluded from bonuses. For Australian players, it’s crucial to note that under the Interactive Gambling Act 1997 (IGA), most online casino games are illegal if offered by unlicensed offshore operators. This guide explains the nuances, but always check local laws.

Understanding Payouts: RTP vs. Volatility

Before identifying specific games, you need to know two key terms:

• Return to Player (RTP): The theoretical percentage of total wagered money a game pays back over millions of spins/hands. A 99% RTP means $99 returned per $100 wagered long-term.
• Volatility/Variance: How often and how much a game pays. Low volatility = frequent small wins; high volatility = rare big wins. High RTP doesn’t guarantee you’ll win quickly.

For Australian players, the best payout game depends on whether you want consistent small returns (low volatility, high RTP) or a chance at a jackpot (high volatility, lower base RTP).

Top High-Payout Online Casino Games

1. Blackjack (Classic Variants)

Blackjack often has the highest RTP of any casino game when played with basic strategy. Standard European or American blackjack with a single deck and favorable rules (e.g., dealer stands on soft 17, no insurance) can achieve RTP of 99.5% to 99.8%. However, many online blackjack variants use 6–8 decks, reducing RTP to 99.2–99.4%. Even so, it remains one of the best payouts. Important for Australians: Live dealer blackjack is often offered by offshore casinos, but the IGA prohibits Australian-licensed operators from providing it. Always verify the casino’s licensing jurisdiction.

2. Video Poker (Jacks or Better, Deuces Wild)

Video poker combines slot simplicity with poker strategy. The best variants include:

• Jacks or Better (9/6 paytable): RTP of 99.54% with perfect strategy.
• Deuces Wild (full pay): RTP up to 100.15% (rare, usually capped at 99.8% online).
• Bonus Poker: RTP around 99.2%.

These games are less common in Australian-facing casinos due to IGA restrictions, but some offshore sites offer them. They require skill—mistakes drop RTP significantly.

3. Slots with Highest RTP

Most online slots have RTP between 92% and 96%. However, a few titles stand out:

• Mega Joker (NetEnt): 99% RTP (with Supermeter mode).
• Ugga Bugga (Playtech): 99.07% RTP.
• Blood Suckers (NetEnt): 98% RTP.
• 1429 Uncharted Seas (Thunderkick): 98.6% RTP.

These are low-to-medium volatility, meaning they pay frequently but not huge jackpots. Progressive jackpot slots (e.g., Mega Moolah) often have low base RTP (88–92%) but can pay millions—payout “value” depends on jackpot size vs. wager.

4. Baccarat (Player Bet)

Baccarat’s Player bet has an RTP of 98.76% (Banker bet is 98.94% but includes a 5% commission, netting ~98.6%). It’s simple, fast, and widely available. Australian players can find it at offshore live casinos, but again, not via licensed domestic operators.

5. Craps (Pass Line / Don’t Pass)

Craps offers some of the best odds in any casino. The Pass Line bet has a house edge of just 1.41% (RTP 98.59%). Don’t Pass is even better at 1.36% (RTP 98.64%). Online craps is rare in Australia due to IGA restrictions on “live” table games, but virtual versions exist.

Australian Legal Context: The IGA 1997

Under the Interactive Gambling Act 1997 (IGA), it is illegal for any operator to provide “real-money” online casino games (slots, table games, poker) to Australian residents unless they hold a license from a state or territory government. In practice, no Australian state has issued such licenses for casino games—only for sports betting and lotteries. As a result:

• All online casinos offering slots, blackjack, or video poker to Australians are offshore operators (e.g., licensed in Malta, Curacao, or the UK).
• The Australian Communications and Media Authority (ACMA) actively blocks unlicensed sites, but enforcement is inconsistent.
• Players are not prosecuted for using offshore casinos, but they have no legal recourse if the casino fails to pay out—this is critical when chasing high-RTP games.

Therefore, while a game might “pay out the most” in theory, the practical risk of dealing with unregulated operators can negate the advantage. Always check if the casino is licensed by a reputable authority (e.g., UKGC, Malta Gaming Authority) and has fair RTP audits.

Hidden Factors Affecting Actual Payouts

• Bonus Wagering Requirements: A 98% RTP slot is useless if you must wager 40x a bonus—your effective RTP plummets.
• Game Provider RTP Variations: The same slot (e.g., Starburst) can have different RTP settings (96.1% vs. 94.0%) depending on the casino. Always check the game’s info page.
• Currency and Payment Fees: Australian Dollar (AUD) deposits may incur conversion fees from offshore casinos, reducing net payout.
• Withdrawal Limits: High-payout games are useless if the casino caps monthly withdrawals at $5,000.

Key Takeaways for Australian Players

• Highest theoretical RTP: Blackjack (99.5%+ with strategy) and video poker (99.54%+) offer the best long-term payouts. Slots rarely exceed 99%.
• No legal domestic options: Under the IGA 1997, you cannot play these games at an Australian-licensed casino. Only offshore sites are available, which carry regulatory and security risks.
• RTP is not a guarantee: Even a 99% RTP game can lose you money quickly in the short term. Only play with money you can afford to lose.
• Check game settings: Always verify the RTP displayed in the game’s paytable. If it’s below 96%, avoid it—there are better options.
• Prioritise safety over RTP: A 97% RTP game at a licensed, audited offshore casino is safer than a 99% game at an unregulated one. Never deposit at a site that doesn’t publish independent RTP audits (e.g., eCOGRA, iTech Labs).
• Use free play first: Before wagering real money, practise blackjack strategy or video poker on free demos to maximise your theoretical return.

Ultimately, no game “pays out the most” in every situation. The best choice is a high-RTP game you understand, played at a trustworthy offshore casino, with strict bankroll management. But remember: the house always has an edge—over time, you will lose. Play responsibly.
