Understanding the House Edge
Every casino game has a built-in mathematical advantage for the house, known as the house edge. This is the percentage of each bet that the casino expects to keep over the long run.
The house edge varies dramatically between different types of games, and even between different variants of the same game. Games that require skill and strategy tend to have lower house edges than pure games of chance.
Pokies (Online Slots): The Numbers
Online pokies typically have RTPs (Return to Player) ranging from 92% to 98%, meaning the house edge ranges from 2% to 8%. The average online pokie has an RTP of approximately 96%, giving the house a 4% edge.
However, it is important to understand that RTP is calculated over millions of spins. In any given session, your results will vary wildly due to the high volatility inherent in most pokies.
Table Games: The Numbers
Table games generally offer significantly better odds than pokies. Blackjack, when played with optimal basic strategy, can have a house edge as low as 0.5%. Baccarat offers a house edge of 1.06% on banker bets. European roulette has a house edge of 2.7%.
The key advantage of table games is that many of them involve an element of skill or strategy. In blackjack, your decisions directly impact the house edge.
So Which Should You Play?
From a pure mathematics perspective, table games offer better odds. If your primary goal is to maximise your playing time and minimise your expected losses, table games like blackjack, baccarat, and craps are the better choice.
However, pokies offer the possibility of life-changing wins from a small bet. Progressive jackpot pokies can pay out millions from a single spin, which is simply not possible at most table games.
Ultimately, the best game to play is the one you enjoy most. The entertainment value of gambling should always be the primary consideration.
Volatility: Why the Same RTP Feels Completely Different
Two pokies can have identical 96% RTPs and feel like completely different games. That is because RTP describes the long-run average return, while volatility describes the distribution of outcomes along the way. A low-volatility pokie hits small wins frequently — you might see a win every third or fourth spin, keeping your balance relatively stable. A high-volatility pokie can go 50 or 100 spins without a meaningful win, then deliver a massive bonus round payout that more than makes up for the dry spell.
Table games occupy a different volatility profile altogether. Blackjack at basic strategy is extraordinarily low volatility — the house edge is tiny and results accumulate slowly. A single roulette number bet is high volatility: 35-to-1 payouts with matching long odds. Understanding volatility helps you match your game choice to your bankroll and risk appetite. A NZ$50 session on a high-volatility pokie can disappear in five minutes; the same NZ$50 on blackjack might give you an hour of play.
Bankroll Management: The Only Guaranteed Winning Strategy
Neither pokies nor table games offer a mathematical path to guaranteed profit against an honest casino. The house edge is mathematically unbeatable over the long term regardless of game choice. What you can control is how long you enjoy the entertainment for a given budget — and this comes down to bankroll management rather than game selection.
A practical rule for casual players: divide your session budget by your expected hourly loss to estimate playtime. At 1,000 spins per hour on a 96% pokie with NZ$1 stakes, expected losses are NZ$40/hour. At 50 hands per hour of blackjack with NZ$5 stakes and basic strategy, expected losses are NZ$1.25/hour. Same entertainment time cost, vastly different game experience. Whichever you choose, set a stop-loss before you start, and stick to it. The most profitable decision any player can make is the decision to stop when the budget is gone.
Frequently Asked Questions
Q: Which casino game has the best odds? A: Blackjack with optimal basic strategy has the lowest house edge of any standard casino game, often as low as 0.5% depending on the rule variant.
Q: Are online pokies rigged? A: No, licensed pokies use certified random number generators that are independently audited. The house edge is built into the math, not achieved through rigging.
Q: What is a good RTP for a pokie? A: 96% is roughly average, 97% or above is very good, and anything below 94% is poor value. Always check the RTP before playing.
Q: Can I count cards in online blackjack? A: Not effectively. Most online blackjack games shuffle the deck after every hand, neutralising any card counting advantage.
Q: Do table games contribute fully to bonus wagering? A: Usually not. Table games typically contribute 10-20% toward bonus wagering requirements, while pokies contribute 100%. Check each bonus's game contribution table.
