How to Calculate Winnings From a Slot Paytable

What a slot paytable tells you

A paytable is the rulebook for one machine. It lists every symbol, every combination that pays, and the amount each combination returns. On older three-reel machines it was printed on the glass. On modern video slots it lives behind an info button, and it usually runs across several screens.

The key thing to understand is that a paytable does not list money. It lists multipliers or credits. A row that says "five cherries pays 50" means 50 credits, not 50 dollars, euros or yen. What a credit is worth depends on your coin value and bet size, which is a separate setting on the machine.

Paytables also tell you which bet the figure applies to. This is the single most common source of confusion. A line win of 50 credits on a machine where you bet 1 credit per line pays 50 credits. The same win on a machine where you bet 5 credits per line pays 250 credits. The paytable number did not change. Your bet did.

Most paytables are organized the same way:

• Line wins: matching symbols on a payline, paid left to right from reel one
• Scatter wins: matching symbols anywhere on the reels, paid regardless of position
• Bonus and feature triggers: how many symbols start free spins or a bonus round
• Special symbols: wilds, scatters, and any symbol with a dual role

The paytable also states the machine's rules on wild substitution, whether wins pay both ways, and how many paylines or ways the game has. Read those lines before you read the payout numbers, because they change how the numbers apply.

One more thing worth knowing: not all slot machines are built the same. Some pay smaller amounts more often, others pay rarely but with bigger prizes¹. The paytable shows you which type you are looking at, because a game full of small three-symbol pays behaves very differently from one where almost all the value sits in the top row.

How to calculate a line win step by step

A line win is the simplest calculation on any slot. Here is the process.

1. Identify the winning combination. Note the symbol and how many matched, and confirm they sit on an active payline starting from the leftmost reel.
2. Find that row on the paytable. Match the symbol and the count. A four-symbol win has its own row, separate from the three-symbol and five-symbol rows.
3. Read the payout figure. It will be a multiplier (like 10x) or a credit amount (like 100).
4. Check which bet it applies to. The paytable header or footnote states whether line wins use the line bet or the total bet. On most games it is the line bet.
5. Multiply. Payout figure times the relevant bet equals your win.

A worked example makes this concrete. Suppose you are playing a game with 20 paylines and you set your bet at 1 credit per line, so your total bet is 20 credits. You land five of the top symbol on one payline, and the paytable lists five of that symbol at 50x the line bet. Your win is 50 times 1, which is 50 credits. Your total bet was 20 credits, so the win is larger than your total stake.

Now change one variable. Same game, same win, but you set your bet at 5 credits per line. Your total bet is 100 credits. The win is 50 times 5, which is 250 credits. The multiplier never moved. Only your bet did.

This is why two players can hit the same combination on the same machine and walk away with very different amounts. The paytable is fixed. The bet is yours to set.

The same multiplication logic applies across regulated betting products everywhere. A Korean single win bet of KRW 2,000 at odds of 1.2 returns KRW 2,400, which is simply 2,000 times 1.2⁵. A Japanese WINNER ticket pays odds times purchase amount⁶. The structure is identical: a published multiplier applied to the amount you staked.

Multipliers, scatter pays and bonus rounds: where calculations change

Line wins are straightforward. The complications start when you leave the paylines.

Scatter pays. Scatters pay anywhere on the reels, which means they can land on reels one, three and five with nothing in between and still pay. The critical question is what they multiply. Most modern slots pay scatters on the total bet, which is why a scatter win often looks bigger than a line win for the same symbol count. Older line-based machines sometimes pay scatters on the line bet. The paytable states which, usually in a footnote on the scatter row. If you cannot find it, assume nothing and check the game's help screen.

Multipliers. A multiplier applies to a win after it is calculated, not before. If you land a 10x line win and a 3x multiplier is active, you get 30x. Multipliers can come from wild symbols, from a bonus feature, or from a random trigger. The paytable's feature section explains where each multiplier comes from and what it applies to.

Bonus rounds. Bonus winnings are usually calculated one of two ways. Either the round applies a multiplier to your triggering bet, or it awards a fixed credit amount per symbol collected. Free spins typically carry a multiplier that applies to each spin's win, and that multiplier is stated in the paytable. The important detail is whether the bonus uses your line bet or your total bet as its base. On a 20-line game, that difference is a factor of 20.

Progressive jackpots. These are their own category. In Macau, progressive jackpot poker rules set the top prize at either a fixed amount or 100% of the jackpot pool, whichever is higher, with the next tier at 10% of the pool or a fixed prize, whichever is higher⁷. That structure is specific to that game, but it shows the principle: a progressive paytable can pay a percentage of a pool rather than a fixed multiplier, and the paytable states the percentage.

Rounding rules. Some jurisdictions round payouts in specific ways. Korean Baseball Toto Special rounds winnings up to the nearest unit and pays a minimum of KRW 100 where the calculated win falls below that⁸. Golf Toto Special uses the same rule⁹. Slot paytables rarely round, because credits are already whole numbers, but if you play a game with fractional credits, check the rules.

Variable prizes. Not every payout is fixed at the moment you bet. Japanese WINNER odds fluctuate with betting volume until sales close¹⁰, and MEGA BIG prize amounts vary depending on total sales and how many entries won¹¹. Slots do not work this way, since the paytable is fixed, but the principle is worth knowing: some products publish a formula, not a number.

RTP and volatility: what the paytable cannot tell you

The paytable tells you what each combination pays. It does not tell you how often those combinations land. That is where RTP and volatility come in, and neither is printed on the paytable itself.

RTP stands for return to player. It is the percentage of all money wagered that the machine is designed to return over the long run. In the Philippines, regulated slot-type electronic games must run an RTP between 90.00% and just under 97.00%³. That range is wide, and it matters. A game at the bottom of that range and a game at the top can have identical paytables and feel completely different over a session.

RTP is not a promise about your session. It is a long-run average across millions of spins. A machine with a high RTP will still take your money on plenty of nights.

Version variance is a real trap. The same slot title can exist in different RTP versions, so the game you played at one casino may not be the same game at another². The fix is simple: open the game's info screen and check the RTP stated there before you play. That number is the one that applies to the machine in front of you.

Volatility describes how the machine distributes its wins. A low-volatility slot pays small amounts often. A high-volatility slot pays rarely but can pay large. The paytable hints at this, because a game with big top-row multipliers and few small pays is high volatility, while a game with lots of small three-symbol pays is low. But the paytable alone will not tell you the hit frequency, which is how often any win lands.

The practical takeaway: use the paytable to understand what a win is worth, and use the info screen to understand how often you might see one. They answer different questions.

When the screen and the payout disagree: disputed wins

This is the part most players never think about until it happens.

A slot machine is a computer, and computers malfunction. When a machine malfunctions, the screen can display a win that the machine's internal records do not support. In that situation, the screen is not the authority. The machine's records and the paytable are.

When a machine and a payout disagree, the machine does not always win the argument. In Macau, regulators have ruled that a player did not win disputed slot machine jackpots, based on casino, inspector and third-party testing reports, and under Macau law a casino need not pay a prize shown by a faulty machine⁴. The practical point for you is simpler: if a screen shows a prize the casino says you did not win, expect the dispute to turn on what the machine's internal records and independent testing show, not on what you saw. Keep your ticket or voucher and ask staff to log the incident before you leave the floor.

The lesson is not that casinos cheat. It is that a displayed number is not a contract. What you are owed is determined by the paytable and the machine's internal accounting. If those disagree with the screen, the screen loses.

What this means in practice:

• If a win looks impossible for the game, it probably is, and it will be reviewed
• Hand pays above a threshold usually involve staff verification before payment
• Keep your own record of what you played and what you were paid, because disputes are easier to resolve with details

That last point is standard practice in regulated betting. Japanese tax guidance for public sports betting payouts tells players to note the race date, venue and race, the amount received, and the amount bet¹². The same habit works for slots: note the machine, the time, and the amount.

Reading paytables in practice: worked examples

Here are three scenarios that cover most of what you will meet.

Example 1: A simple line win. You play a 25-line game at 2 credits per line, total bet 50 credits. You land four of the second-highest symbol on one line. The paytable lists four of that symbol at 25x the line bet. Your win is 25 times 2, which is 50 credits. That is exactly your total bet back.

Example 2: A scatter win. Same game. Three scatters land anywhere on the reels. The paytable lists three scatters at 5x the total bet. Your win is 5 times 50, which is 250 credits. Note how much larger this is than the line win, purely because scatters use the total bet as their base.

Example 3: A bonus round. You trigger free spins with three bonus symbols. The paytable states the feature awards 10 free spins with a 2x multiplier on all wins. During the round you land a line win worth 30 credits at your line bet. The multiplier doubles it to 60 credits. If the paytable had said the multiplier applies to the total bet instead, the same win would be worth 1,500 credits. This is why the base matters.

For comparison, the same multiplication logic shows up in table games and betting products across the region.

In every case, the published figure is a multiplier applied to your stake, and the only variable is the stake.

When you sit down at a new slot, the routine is short. Open the paytable. Find the top symbol row and the scatter row. Check whether each uses the line bet or the total bet. Check the info screen for the RTP. Then set your bet with those numbers in mind. That is the whole skill, and it takes about two minutes.
