Glossary

I review online casinos, and the vocabulary of this industry sits across four areas that most glossaries treat separately: game maths, software mechanics, bonus terms, and compliance regulation. Understanding all four is what separates players who make informed decisions about where and how to play from those who discover important terms for the first time when something goes wrong. This glossary covers all four areas in plain New Zealand English — with the reviewer's lens on which terms genuinely matter and which are mostly marketing noise.

How do you evaluate a licensed casino — and what does Guts look like through that lens?

When I review a platform, I apply criteria in order of importance. The framework is a funnel: platforms that fail the first criterion don't get evaluated on the second. Guts clears every level of the evaluation framework, which is why it earns a proper recommendation for Aussie players rather than a conditional one.

Author's tip from Ryan Gallagher, Online Casino Reviewer: "The bonus terms layer scores lower than the others not because Guts's terms are particularly bad — the 10× wagering cap is the regulated maximum in New Zealand — but because bonus terms always require player attention regardless of the platform. The game contribution rate for live casino is the term most players miss. Always check it before accepting any offer."

What are the core game maths terms every New Zealand casino player needs?

House edge — the casino's mathematical advantage on every bet, expressed as a percentage. Lower is better for the player. Blackjack with basic strategy: 0.42%. French roulette with La Partage: 1.35%. Baccarat banker bet: 1.06%. American roulette: 5.26%. The house edge is the single most important number when comparing games — it tells you the expected cost per NZ$ wagered over the long run.

RTP (Return to Player) — the inverse of house edge applied to pokies. A 96% RTP means NZ$96 returned per NZ$100 staked in the long run. Published in every game's info panel at Guts and independently audited under New Zealand licensing requirements. Higher is better.

Volatility — how a pokie distributes its payouts. Low volatility: frequent small wins. High volatility: rare larger hits after extended dry spells. Matching volatility to your session length and NZ$ bankroll is the most practical pre-game decision a pokies player can make.

Expected value (EV) — the mathematically predicted return on any single bet over a very large number of repetitions. A negative-EV bet loses money in the long run; a positive-EV bet would make money in the long run. All casino games are negative-EV for the player — the question is how negative. Blackjack with basic strategy at -0.42% EV is far less costly than American roulette at -5.26% EV per NZ$ wagered.

Variance — the degree of deviation from expected value across a session. High variance means your actual results can swing significantly from the EV prediction over short periods. This is why a high-volatility pokie can produce a session loss far larger than its RTP would predict — and why session length matters when choosing a game.

Basic strategy — in blackjack, the mathematically optimal decision for every combination of player hand and dealer upcard. Following it consistently brings the house edge to its minimum achievable value. Deviating from it — however confidently — increases the effective house edge.

La Partage — a French roulette rule that returns half your even-money stake when zero lands, reducing the house edge from 2.70% to 1.35% on those bets. Available on Evolution's French Roulette tables at Guts. Always choose it over European roulette when even-money bets are your primary play.

Author's tip from Ryan Gallagher, Online Casino Reviewer: "The single most valuable insight from this table is the blackjack vs American roulette comparison. Most Aussie players don't realise the gap is that wide — NZ$0.42 versus NZ$5.26 per NZ$100 bet means American roulette costs more than 12× as much as optimal blackjack. Choosing your game based on house edge rather than lobby aesthetics is the highest-value decision most casino players can make."

What bonus, account and compliance terms do New Zealand players need?

Full KYC and verification details are on the login page. The terms below cover what you'll encounter at Guts when managing your account, evaluating offers, and moving NZ$.

Author's tip from Ryan Gallagher, Online Casino Reviewer: "The game contribution rate is the bonus term I highlight in every casino review I write, and Guts is no different. If you're planning to use a welcome bonus primarily at the live blackjack tables, check what blackjack contributes toward the wagering requirement before accepting. It's commonly 0–10%. That single number changes whether the offer is worth having at all."

Quick-reference: key comparison terms for evaluating Guts against other platforms

For the full Guts review — scorecard, category ratings, and what the platform looks like against the broader licensed NZ-facing field — the home page covers it in detail. For account setup, KYC, and login guidance, the login page walks through everything step by step. Gambling is entertainment for adults who are 18 and over — and understanding the terms means you're making informed decisions rather than discovering them after the fact.
