How do I read and understand a paytable on an online slot machine?

Before you spin a single credit, the paytable is the one document that tells you exactly what you're playing for — and on a modern online slot, it holds a lot more information than most players bother to check. Here's how to pull it apart and actually use it.

Finding it and what's inside

On online slots, the paytable is usually accessible through a "Help" button or an "i" icon on the game screen. Tap it before your first spin. The paytable is the key to knowing your slot machine's payouts — it shows you the prize value, winning symbol combinations, and which bet sizes correspond to each prize.

Most paytables are laid out in sections. The first thing you'll see is a symbol hierarchy: the highest-paying symbols (often the game's themed characters or special icons) listed at the top, with lower-value card-rank symbols (A, K, Q, J, 10) further down. Each symbol entry shows you how many matching symbols in a row you need, and what that combination pays — typically expressed as a multiplier of your line bet. So "5× wild = 500x" means landing five wilds on an active payline pays 500 times whatever you wagered per line.

That "per line" part matters. You can bet on as many paylines as are available, but each additional line increases your cost per spin — and the bet per line is the number of betting units or credits wagered per line in play. A payout that looks generous in the table can shrink considerably once you divide it by the total bet you placed across all lines. Always read the prize against your total stake, not just the line bet.

Paylines, wilds, scatters, and bonus triggers

Paylines — sometimes called "betting lines" or "winning lines" — are the ways symbols can line up for a win. Modern slots typically feature a variety of paylines, including diagonal and zigzag patterns, and winning combinations can vary from one to thousands. The paytable will include a diagram of every active payline shape so you can see exactly which paths count. Some slot games have fixed paylines, meaning you skip the line-picking step altogether — with each spin you bet on a preset number and type of paylines.

Wild symbols act as substitutes for other symbols to complete a winning combination. If one or more symbols can be substituted by a wild symbol, resulting in a winning combination with the same pay as that using the original symbols, then both combinations are considered to be the same award. Scatter symbols work differently — they usually pay anywhere on the reels regardless of paylines, and they're commonly the key to triggering bonus features. The paytable explains in simple terms what needs to happen for a bonus to activate, and what exactly the bonus will be — a free spin, a minigame, or something else.

One catch worth flagging: sometimes with progressive jackpots, you have to bet a certain amount — often the max bet — to be eligible to win the jackpot. Always read the paytable to find out if a max bet is required. If you're playing at a lower stake to stretch your session, confirm you're still qualifying for every prize tier shown.

RTP — the number behind the numbers

How much a casino pays out in winnings, on average over the lifecycle of the game, is called the return-to-player (RTP) percentage. Many online slots display their RTP in the paytable or help screen. If the RTP of a game is 85%, then over time the house keeps 15% as the house edge — meaning over a long-term period, the house would pay out on average 85% of its earnings to the winners and keep 15% for profit. Crucially, when the payback percentage is 85%, this doesn't mean you can expect to win back $85 if you gamble $100 in that individual session. RTP is a statistical average across millions of spins, not a session-by-session guarantee. The AGCO sets a minimum payback standard for Ontario, and individual titles vary above that floor — the game's own paytable or the operator's game-info page is where you'll find the specific figure for a given title.

One more thing worth knowing: payout odds vary based on the machine — two slot machines may look identical yet have different odds. Every machine is different; even if they look the same, two machines can pay very differently. Never assume a game pays the same as a visually similar one — read that paytable fresh each time.

Make sure you're playing on a site registered in Ontario's regulated market; legitimate operators display both the iGaming Ontario and BetGuard logos, which confirm the site is managed by iGaming Ontario and regulated by the AGCO. The full list of registered operators is at the iGaming Ontario website. And if gambling ever starts eating into time or money you hadn't planned to spend, ConnexOntario (1-866-531-2600) is there — as is BetGuard at betguard.ca, where anyone 19+ can self-exclude from all Ontario-licensed sites in a single step.
