How to read a slot's paytable properly

A paytable is the game’s own rulebook: the screen, usually opened through an “i” or menu icon, where the studio lists what each symbol pays, how wins are formed and what the bonus features do. It is the one document about a slot that comes from the people who built it, which is why we treat it as the starting point for any game we describe.

Most paytables run over several pages, and the order is fairly standard across studios.

The first pages usually show symbol values, either as multiples of the total bet or as cash amounts that change when you change your stake. Then come the win rules: whether the game pays left to right on fixed lines, in both directions, on “ways” where matching symbols only need to sit on adjacent reels, or on clusters of touching symbols. After that sit the special symbols, typically wilds and scatters, followed by the feature descriptions and, near the end, the general rules page.

The page most players skip

That final rules page is where the useful small print lives. It is where the theoretical RTP is normally stated, along with the maximum win, a note that malfunctions void all pays and plays, and sometimes the hit frequency or volatility rating. RTP, or return to player, is the share of all money staked that a game is designed to pay back over a very large number of spins. It describes the machine across millions of rounds, not the next hour of anyone’s play, and a paytable that states it is telling you about the game’s design rather than making a promise about your session.

Many studios certify a single game at several RTP settings and let each casino choose which one to run. A title might exist at around 96%, 94% and lower configurations, and the artwork, symbols and features look identical across all of them. Directories that track these figures note the same thing: the recorded RTP is one configuration, and the live game screen is where the version on offer is confirmed.

The difference sounds small. It is not.

Take €500 staked in total over an evening. At a 96% setting the long-run average return on that amount is €480, so the expected cost is €20; at 94% the average return falls to €470 and the expected cost rises to €30, half as much again. Neither figure predicts what happens in one session, where results swing far above and below the average, but across a year of play the lower setting simply costs more. The paytable is the only place you can see which version you have, which is why reading it at the specific casino matters more than reading a review of the game elsewhere.

There is also a regulatory angle for readers in Ireland. We checked the position of the Gambling Regulatory Authority of Ireland, set up under the Gambling Regulation Act 2024: its first licences, issued from 1 July 2026, cover betting, and online casino licensing is a later phase. Until remote gaming licences are issued, any slot an Irish player opens runs under a licence granted in another jurisdiction, and the RTP rules that apply are that jurisdiction’s.

Volatility describes how a slot’s returns are spread out: a low-volatility game pays small amounts often, while a high-volatility one pays rarely but can pay large sums when it does. Some studios print a rating, often as a scale of lightning bolts or a word such as “high”, while others leave it out entirely.

Where no rating is given, the symbol values still offer clues. A game whose top symbol pays a few times the bet for five of a kind, with a modest maximum win, tends to behave gently. A game where most of the value sits in the bonus round, with a maximum win stated in the thousands of times the stake, usually means long dry spells between meaningful wins.

Hit frequency, the share of spins that return anything at all, is printed less often. When a paytable gives it as, say, one spin in four, remember that many of those hits return less than the stake, so a “win” can still leave you down on the spin. If the paytable does not state it, we say so rather than estimate it, because a guessed hit frequency is worse than none.

One myth deserves a direct answer here: a slot is never “due” a win. Each spin is decided by a random number generator independently of the last, and a long run of losses changes nothing about the next result.

The most frequent error is reading symbol values as cash when the paytable shows them as multiples, or the reverse. A “x50” beside a symbol at a €0.20 stake is a €10 win, not €50, and a quick stake change on screen settles which format the game uses.

A second mistake is treating RTP as a return on each session.

A 96% figure is a long-run average over millions of spins, so one evening that ends well above or below it proves nothing about the game, and neither does a friend’s lucky streak on the same title. In the same way, the stated maximum win is a ceiling built into the maths, reached so rarely that it should not shape your expectations; some paytables state it as a multiple of the stake and cap any win at that level, ending the feature early once it is hit. Read that clause before assuming a bonus round can run on indefinitely.

Finally, check the malfunction clause and any note on unfinished rounds. These explain what happens if your connection drops mid-feature, which in most cases means the round completes on the server and the result appears when you reload the game.
