Open the information screen on almost any slot, and you’ll find a paytable somewhere inside it. At first glance, it’s normally just a collection of symbols with numbers next to them, but there’s a lot of game maths sitting behind those numbers.
For example, the highest-paying symbol can’t appear as often as everything else. Payouts, symbol frequencies, bonus features, and the game’s overall return all have to work together.
Below, we’ll look at what a slot paytable at an online casino shows and how it helps balance smaller regular wins with bigger, rarer payouts.
What You Will See on a Slot Paytable
The obvious thing is how much each symbol combination pays.
One symbol might pay for three, four, or five matching symbols, with the payout increasing each time. A lower-value symbol could pay relatively small amounts, while the game’s premium symbol might offer a much bigger multiplier for landing five across the reels.
Paytables can also explain things like:
- Wild symbols and what they substitute for
- Scatter symbols
- How many symbols are needed to trigger a bonus
- Free spins
- Multipliers
- Paylines or ways to win
- Special features that change payouts
Some games have very simple paytables. Others need several pages just to explain what everything does.
How Slot Paytables Balance Risk and Reward
The payout shown on the screen is only half the story. You also need to know how likely that winning combination is, and a paytable won’t always tell you that.
Imagine one symbol pays 500x your bet and another pays 2x. It would obviously be a very different game if both appeared at the same frequency.
Instead, game developers can make high-value symbols less common while lower-paying symbols appear more regularly. Reel layouts and symbol weightings are part of the maths behind that. Analyses of traditional slot designs show that changing how often each symbol appears on the reels directly changes both the probability of a win and its contribution to the game’s overall return.
Then you’ve got bonus rounds, jackpots, and other features taking up part of the game’s return.
Gaming Laboratories International explains that RTP analysis can look separately at contributions from the base game, feature games, and jackpots, as well as the game’s volatility.
That’s where risk and reward really come from. A slot can put more of its potential return into occasional large prizes, or spread more of it across smaller wins. Two slots could even have a similar RTP and feel completely different to play because those payouts are distributed differently.
The Most Important Information on a Slot Paytable
Start with what actually creates a win by checking how many matching symbols you need, whether they have to land from the leftmost reel, and whether the game uses fixed paylines, ways to win, or another pay mechanism.
Then look at wilds and scatters, which typically behave differently from normal symbols. A wild might replace other symbols but not the scatter, while three scatters could trigger free spins even if they’re not on a normal payline.
Payouts, either presented as cash values or paid odds, are also crucial. However, remember that the biggest win on the paytable doesn’t necessarily define the best slot; it can be rare, and the chances of hitting it are hard to estimate from paytable data alone.
Therefore, always check them before playing. It would take no more than five minutes to examine the game’s basics instead of wasting time trying to guess the probabilities just by looking at the reels and symbols.
