Random Number Generators (RNGs)
Every online casino game uses a Random Number Generator — a piece of software that produces unpredictable outcomes for each spin, hand, or roll. A certified RNG ensures that past results have no influence on future ones, and that the casino cannot manipulate outcomes. All NZ-licensed casinos must use RNGs certified by an accredited testing laboratory.
Return to Player (RTP)
RTP is the percentage of all wagered money a game pays back to players over a very large number of rounds. A slot with 96% RTP will, on average, return NZD 96 for every NZD 100 wagered. RTP is a long-run statistical average — it does not mean you will get back 96% of your money in a single session.
House edge
The house edge is the flip side of RTP. A game with 96% RTP has a 4% house edge — the casino's mathematical advantage. Blackjack with basic strategy has a house edge below 0.5%. Pokies typically range from 2% to 10%. The lower the house edge, the better the odds for the player.
Volatility
Volatility (also called variance) describes how a game pays out. High volatility slots pay large amounts infrequently. Low volatility slots pay smaller amounts more often. Neither is better — it depends on your playing style and bankroll. High volatility games require a larger bankroll to ride out losing streaks.
Live casino games
Live casino games stream a real dealer from a studio. Cards are shuffled physically and roulette wheels are spun by a human. The outcomes are still random, but the game is not driven by an RNG — it uses real physical processes. RTPs for live games are comparable to their digital equivalents.
