Bonus buy features explained
A feature buy replaces an unknown number of small stakes with one certain, large one. The arithmetic of that trade is worth understanding before the button is pressed.

Casino guides
Sourced explainers on the maths, mechanics and consumer-protection questions behind casino games.
In short
KiraBet guides explain the concepts behind casino games in plain English: what RTP and house edge measure, how volatility shapes results, how live dealer games operate, how wagering requirements work and how to recognise an unsafe gambling website. Every guide cites its sources, labels worked examples as hypothetical and contains no offers or invitations to gamble.
Game maths
These guides explain the numbers that describe a game. None of them offers a way to beat the house.
- What is RTP? – what return to player measures, and why it is a long-term average
- Slot volatility explained – how two games with the same RTP can behave very differently
- House edge explained – the built-in advantage in table games, with the maths shown
How games work
- How live casino games work – studios, dealers, streaming and where random number generators still play a part
Bonus terms
- Wagering requirements explained – how play-through conditions work and what to check in terms
The bonuses section explains individual bonus types without publishing offers.
Safety
- How to spot unsafe gambling sites – licence checks, clone sites and warning signs in terms and withdrawals
How we write guides
Each guide answers one question. Facts are cited to regulators, providers or reputable publications, and any calculation using invented figures is labelled as hypothetical.
Guides are kept up to date under our editorial policy, and each one shows when it was last updated and fact-checked. If gambling is causing you concern, our responsible gambling page lists free support.
- RTP
- RTP (return to player) is the percentage of all money staked on a game that it is designed to pay back as winnings, averaged over a very large number of plays. It does not predict the result of any single session.
- Volatility
- A measure of how widely a game's results vary around its average return, commonly represented by the standard deviation. High-volatility games pay larger wins less often; low-volatility games pay smaller wins more often.
- House edge
- The average loss on a bet expressed as a percentage of the stake, representing the casino's built-in mathematical advantage. For a game with a fixed return, house edge equals 100% minus RTP.
- Wagering requirement
- A condition requiring a set total of bets to be placed before bonus funds, or winnings from them, can be withdrawn. It is usually expressed as a multiple, such as 10x the bonus amount.

Budgeting for gambling
Gambling has a price per hour, and it can be calculated before you start. This guide shows the arithmetic and what to do with the answer.

Casino payment methods explained
Five questions separate one payment family from another. This guide sets out the framework and points to the detailed page for each method.

Deposit limits, loss limits and reality checks
A deposit limit caps new money, a loss limit tracks the net position, and a spend limit sits between them. Choosing the wrong one is a common and costly mistake.

House edge explained
House edge is the average share of each bet a casino game keeps. Here is how it is calculated, what it looks like across common games and what it does and does not tell you.

How game fairness testing works
Certification is a narrow, documented check with a named tester and a stated scope. Knowing that scope is what separates a meaningful certificate from a badge.

How live casino games work
Live casino games use real dealers and physical equipment, streamed from a studio. Here is who runs them, how a round works, how they are supervised and where the house edge comes from.
ReadGuides · Regulation
How online casino licensing works
A licence is a permission to run named activities on enforceable conditions. Read properly, a licence number answers four questions; it also leaves several important ones unanswered.

How online slots work
The reels are a picture drawn after the fact. This guide follows the chain from stake to outcome, using a published slot design to show where the numbers actually come from.

How random number generators work
Every card, reel stop and wheel position in an online casino game comes from a number. This is where that number comes from, who checks it, and what checking it does and does not prove.

How to spot unsafe gambling sites
A consumer-protection checklist: how to test a licence claim, recognise impersonation and phishing, and read the warning signs in promises, terms and withdrawal rules.
ReadGuides · Accounts
Identity verification and account checks
Two separate legal duties drive account checks: keeping children out, and anti-money laundering law. They arrive at different moments and ask different questions.

Jackpots explained
A jackpot is a way of redistributing a game's return, not of adding to it. This guide covers the three structures in use, how the money reaches the meter, and what the rules must disclose.

Megaways and variable reel mechanics explained
The headline figure on a Megaways game is the ceiling of a range that is redrawn every spin. The floor, rarely advertised, is part of the same design.

Paylines, ways to win and cluster pays explained
Four different rules decide what counts as a win on a slot grid. Telling them apart is the difference between reading a paytable and guessing at one.

Payment security explained
Most payment fraud does not break the bank's controls. It persuades you to approve the payment yourself. This guide covers both halves of the problem.

Recognising gambling harm
Harm rarely arrives as a single event. It accumulates, and the early signs are usually behavioural rather than financial.
ReadGuides · Safety
Responsible gambling tools explained
The account controls exist because a decision made before a session is more reliable than one made during it. That is the whole design principle.

Self-exclusion and blocking tools
No single block covers everything. Four separate layers exist, they work in different places, and the gaps between them are predictable.
ReadGuides · Game maths
Slot volatility explained
Volatility describes how a game's returns are spread out: many small wins, or rare large ones. It shapes how a session feels, but it never changes the long-run cost of play.
ReadGuides · Bonus terms
Wagering requirements explained
A wagering requirement sets how much must be bet before bonus-related money can be withdrawn. Here is how the calculation works, what it costs on average and which terms change it.

What is RTP? Return to player explained
RTP is the share of money staked that a game is designed to pay back as prizes over a very large number of plays. It is useful for comparing games, but it cannot predict a session.

Questions about this section
Do these guides explain how to win at casino games?
No. They explain how games and terms work so readers understand what they are looking at. Casino games are designed with a built-in advantage for the house, and no guide, system or strategy guarantees a win. Gambling always involves the risk of losing money.
Which guide should I read first?
Start with the RTP guide, then the house edge guide. Together they explain how games return money to players over time and why the operator keeps a share. The volatility guide then explains why short-term results can differ so much from those averages.
Are the examples in the guides real offers?
No. Worked examples use invented figures to show how a calculation works and are always labelled as hypothetical. They do not describe any real offer, game result or operator. We do not publish real offers, bonus codes or links to gambling operators anywhere on the site.

Gambling can cause harm
No game gives a guaranteed return, and losses cannot be won back by playing more. If gambling is affecting your money, work, sleep or relationships, support is available — including free services you can contact from the Maldives.
