Every term here appears on casino pages constantly and is explained on almost none of them. Each entry gives the definition, the misreading that follows it around, and a worked example with the arithmetic done — because most of these terms are misunderstood in a specific, predictable way rather than merely being unfamiliar. There are 11 pages below.

11 pages, each one covering a single entry rather than summarising several. Where a field above reads “not published”, the entry’s own page explains who would have had to publish it.
Each entry in a paragraph
Enough on each to know which page is the one worth opening.
RTP
Short for return to player. The share of all wagered money a game returns to players over the long run, expressed as a percentage.
Fixed by: The game studio, when the game is built. Where you meet it: Game spec tables and studio info panels.
The misreading: The common misreading is that a 96% RTP means a player gets 96% of their money back on an evening.
Volatility
Short for also called variance. How a game distributes its returns: many small wins, or rare large ones.
Fixed by: The game studio, as a consequence of the paytable and reel maths. Where you meet it: Game spec tables, usually as a label rather than a number.
The misreading: High volatility is often read as ‘pays more’.
House edge
The operator’s mathematical advantage, and the arithmetic complement of RTP.
Fixed by: The game studio; it is whatever RTP leaves over. Where you meet it: Table game rules and comparisons between game types.
The misreading: A house edge is sometimes described as beatable with a system.
Paylines
The fixed patterns across the reels on which matching symbols pay.
Fixed by: The game studio, as part of the reel layout. Where you meet it: A game’s info screen and its spec table.
The misreading: More paylines is often read as better odds.
Ways to win
Short for including Megaways. A payline alternative where adjacent matching symbols pay regardless of their position.
Fixed by: The game studio, as an alternative to fixed paylines. Where you meet it: Spec tables on cluster and scatter-pays slots.
The misreading: A large way-count is read as a large advantage.
Wild symbol
A symbol that substitutes for others to complete a winning combination.
Fixed by: The game studio, in the paytable. Where you meet it: A game’s paytable and feature list.
The misreading: Wilds are often assumed to substitute for everything.
Scatter symbol
A symbol that pays or triggers a feature regardless of where it lands.
Fixed by: The game studio, in the paytable. Where you meet it: A game’s feature list, usually next to free spins.
The misreading: Scatters are widely believed to become ‘due’ after a dry run.
Free spins
A feature round of spins awarded without an additional stake.
Fixed by: The game studio when it is a game feature; the operator when it is a promotion. Where you meet it: Game feature lists, and separately in bonus terms.
The misreading: Free spins awarded as a promotion by an operator are not the same thing as an in-game free-spin round, despite sharing the name.
Progressive jackpot
A prize pool that grows from a share of every qualifying stake until someone wins it.
Fixed by: The studio or jackpot network that pools the contributions. Where you meet it: Jackpot tickers above the reels, and network jackpot pages.
The misreading: A large jackpot is sometimes read as improved odds.
Wagering requirement
Short for also called playthrough or turnover. The multiple of a bonus that must be wagered before any of it can be withdrawn.
Fixed by: The operator, in its bonus terms — not the studio. Where you meet it: Bonus terms and conditions.
The misreading: Wagering is widely read as ‘deposit this much’.
Bankroll management
Deciding in advance what is at risk, and stopping at that figure.
Fixed by: The player. Nothing else sets it. Where you meet it: Responsible gambling pages and deposit limit settings.
The misreading: Chasing losses is often framed as recovering.
Checking any of this without trusting this site
None of these definitions rests on this site’s authority. Each one can be checked against the game itself:
- Open any slot’s own information screen. The paytable, the way-count and the feature rules are all there, and they are the primary source for every mechanical term defined here.
- Compare a way-count against the grid. A 5x4 grid evaluated as 1,024 ways is 4 to the power of 5 — the number describes the grid’s geometry, not the game’s generosity.
- For a bonus term, read the operator’s own conditions rather than a summary of them. A wagering requirement multiplies a figure, and which figure it multiplies — bonus only, or bonus plus deposit — changes the answer by a factor of two.
- Where a studio publishes no RTP, check whether two sources quoting one agree. On JILI titles they differ by as much as two points, which settles the question of whether either is authoritative.
The thing most often got wrong here
The single most common error across all of these terms is assuming the casino sets them. For most it does not: RTP, volatility, paylines, wilds and scatters are fixed by the studio when the game is built, and the site offering the game cannot adjust them.
The exception is the wagering requirement, which an operator writes into its own bonus terms. Each entry states which of the two it is, because that difference decides who a complaint should go to — and a complaint sent to the wrong one goes nowhere.
What this section does not cover
These pages define terms. They do not rate games or operators, and no entry quotes an RTP for a specific title — the individual title pages handle that, and they say so when the studio publishes nothing.
That omission is deliberate and it is the same on every page in this section. A site that fills those gaps with plausible numbers reads better and is worth less.
FAQ
Which of these terms does a casino control?
On this evidence, one: the wagering requirement, which an operator writes into its own bonus terms. The rest are set by the studio that built the game and cannot be adjusted by the site offering it.
Why do RTP figures differ between sites?
Because some studios do not publish one, and the figures circulating for their titles come from third-party estimates that disagree with each other. Two comparison sites quoting different numbers for the same game are usually both unsourced.
Are these definitions specific to the Philippines?
No. Slot mechanics are properties of the games and are the same everywhere. What is Philippine-specific is the payment and licensing context, which the payment and provider sections cover.
What is the difference between RTP and volatility?
RTP is how much a game returns over the long run. Volatility is the shape of how it returns it. Two games can both return 96% while one pays small amounts constantly and the other pays almost nothing until it pays enormously, and the two feel nothing alike.
Is a high maximum win a good sign?
It is a ceiling with a vanishingly small probability attached, not a forecast. A game can publish a 100,000x maximum and a medium volatility label at the same time, which is a signal that the ceiling is an accounting figure rather than an outcome to plan around.
Where do these definitions come from?
From how the mechanics work, which is checkable in any game's own information screen. None of them depends on a claim about an operator, and none quotes a figure for a specific title.
