Slot Machine Paytable Analysis
The pay table is the most important piece of public information available on any slot machine. Most players ignore it entirely. Professional advantage players use it to estimate RTP, identify volatility, spot bonus conditions, and make smarter machine selection decisions before inserting a single dollar.
Pay Table Basics
Every slot machine has a pay table — a complete list of what each winning symbol combination pays. On video slots, access it by pressing the Info or Pay Table button on the screen. On older reel-spinning games, it is printed on the machine glass or displayed on the top box screen.
The pay table answers two fundamental questions: what wins, and how much does it pay? Understanding the answers tells you far more about a machine than the theme, the button layout, or the bonus animation. The pay table is the financial blueprint of the game.
One critical distinction: some games express awards as multiples of the line bet, while others express them as multiples of the total bet. A game paying 100x line bet with 25 lines active costs $0.25 per line. Your 100x win is $25. The same 100x award on a total-bet machine with a $0.25 total bet is only $25 — but your cost per spin is already $0.25 total, not $6.25. Always confirm whether the pay table multipliers reference line bet or total bet before calculating your effective cost-per-win ratio.
Symbol Hierarchy and Pairing
The arrangement of symbols in the pay table from highest award to lowest award is not random — it is a deliberate volatility signal. Understanding the ratio between award tiers reveals how the game is designed to distribute value across spins.
In a low-volatility game, you will typically see 4 to 6 symbol tiers where the highest award is perhaps 5 to 10 times the lowest-tier award for 5 of a kind. Common wins come frequently because the lower-value symbols appear on the reels at high frequency. In a high-volatility game, the pay table may show a top award that is 50 to 100 times the lowest award for 5 of a kind, with large gaps between tiers. Common symbols pay very little, and most of the game value is concentrated in rare top-line hits or bonus rounds.
Count the pay table tiers.
A 3-tier symbol structure (high, medium, low) indicates a simpler volatility profile. An 8-tier structure with large gaps between tiers indicates high volatility with infrequent but large wins.
Look at the 5-of-a-kind top to 3-of-a-kind bottom ratio.
Divide the 5-of-a-kind award for the top symbol by the 3-of-a-kind award for the lowest symbol. A ratio above 50:1 is a high-volatility signal. A ratio below 15:1 suggests lower volatility.
Check for 2-of-a-kind pays.
Games that pay for landing just 2 of the top symbol return wins frequently. This is a lower-volatility design feature. If the pay table only starts paying at 3 of a kind for all symbols including the top symbol, expect longer losing streaks.
Low-value symbol pays reveal return structure.
If the lowest-value symbol pays 1x for 5 of a kind and 0x for 3 or 4, the game is paying very little on common hits. Much of the RTP must be loaded elsewhere — in the top symbol or in the bonus round.

Scatter and Bonus Triggers
The scatter and bonus trigger section of the pay table is where many players stop reading because the information looks technical. It is actually the most strategically important section — it tells you how the game distributes its bonus round EV relative to base game play.
Scatter pays are listed separately from line pays and reference total bet rather than line bet. Landing 3 scatters on a $1 total bet game paying 2x total bet for 3 scatters gives you $2 immediately plus the bonus round. That immediate scatter pay is part of the game's overall RTP contribution from the bonus trigger event.
Progressive Contributions
On progressive jackpot games, a percentage of every bet is removed from the game and added to one or more jackpot meters. This contribution rate is not usually stated in the pay table, but its effects are visible in the pay table structure.
When a game funds a large progressive jackpot, the base game pay table is typically lower than a comparable non-progressive game. The contribution rate comes directly out of the base RTP. A game contributing 5% of every spin to a progressive pool has 5% less base-game RTP than an identical game without the progressive.
For must-hit-by progressives — the primary advantage play target on our 200+ machine guides — the pay table helps you understand the base game structure you are working with while the progressive meter climbs. See the slot machine RTP explained guide and the reel mechanics guide for how progressive contributions interact with base RTP.
Compare base pays to similar non-progressive games.
If a progressive game shows base-game symbol pays that are 20% to 30% lower than comparable non-progressive games from the same manufacturer, the difference is likely going to the jackpot contribution pool.
Jackpot trigger requirements.
Some pay tables list the jackpot trigger condition (land 5 jackpot symbols on a specific pay line at max bet). Others require a randomly triggered bonus round. Games with bet-dependent jackpot triggers should always be played at the required qualifying bet level.
Jackpot reset values.
If the pay table lists a starting seed value for the jackpot after it hits, that is useful for must-hit-by analysis. Combined with the ceiling value (usually displayed on the machine), you can calculate the range for EV calculations.
Multiple jackpot tiers.
Games with Mini, Minor, Major, and Grand tiers load progressively more of their contribution into the upper tiers. The Mini and Minor are funded more quickly (hit more often) while the Major and Grand accumulate over longer periods. The pay table section for jackpots lists each tier and its seed value.
Estimating RTP from Paytable
You cannot calculate exact RTP from the pay table alone without the reel strips, but you can make a rough EV estimate using the pay table data combined with published RTP ranges for the manufacturer and game family. The Run the Slots EV Calculator and the pay table guide provide tools and reference ranges for this analysis.
The most useful technique is comparative analysis: look at the same game at different denominations. Manufacturers often increase RTP at higher denominations while keeping the symbol pay structure identical. If you find two cabinets of the same game at different denominations, the higher denomination version is almost always the better EV choice for free play or promotional redemption.
Step 1: Identify the pay table tier structure.
Count symbol tiers and note the top award. A top award above 1,000x signals that significant RTP is loaded into rare events.
Step 2: Sum the approximate contribution of each tier.
For each symbol tier, roughly estimate how often it hits (low/medium/high frequency) and multiply by the award. This gives a qualitative picture of where the RTP is distributed — not a precise number, but directionally useful.
Step 3: Cross-reference with manufacturer RTP ranges.
Most major manufacturers publish RTP ranges by game family in their regulatory filings or certified configuration sheets. IGT, Aristocrat, Konami, and AGS machines have documented RTP ranges available publicly.
Step 4: Apply context from similar machines.
If you have played the same game family extensively, your empirical data on win frequency per denomination is useful calibration. Combine it with the pay table structure for a more grounded estimate.
Red Flags in Pay Tables
Some pay table structures are specifically designed to appear more generous than they are. Recognizing these patterns helps you avoid machines that look attractive but return below-average value.
Massive top award with tiny common-symbol pays.
A game advertising a $10,000 jackpot while the most common 5-of-a-kind combination pays only 2x is loading almost all its RTP into one extremely rare event. Unless you are specifically there for the jackpot, the base game is returning very little on normal play.
Scatter pays expressed in total-bet pennies.
A pay table showing scatter pays of 0.02x, 0.05x, 0.25x for 2, 3, 4 scatters on a total-bet basis is returning nearly nothing on the scatter symbol itself. All the value is in the bonus round. If the bonus triggers infrequently, expect long stretches of near-zero return from base game play.
No 2-of-a-kind pays on any symbol.
When every symbol in the pay table requires 3 matching symbols for the minimum win, every spin that produces only 2 matching symbols returns nothing. This is a high-volatility, low-frequency-win structure that burns through bankroll quickly.
Bonus game round not described in pay table.
When the pay table says only 'bonus game' with no further description of what the bonus pays, the casino or manufacturer is deliberately obscuring the expected value of the bonus. This is not illegal, but it is an information disadvantage for the player.
Maximum bet jackpot that scales linearly.
Some games scale all awards proportionally with bet size, so a max bet of 5x the minimum bet pays exactly 5x more on every symbol. There is no edge for playing maximum bet on these games — the RTP is identical at any bet level. Only play max bet when the pay table confirms a non-linear jackpot benefit at maximum bet.
Frequently Asked Questions
How do you read a slot machine pay table?
Open the pay table by pressing the Info or Pay Table button on the machine. The pay table lists every symbol from highest to lowest value, the number of coins or credits awarded for each winning combination, and the number of matching symbols required on a pay line. Read from top to bottom — the top symbol is the highest award. Note whether pays are for line bets or total bets, because the multiplier structure changes your effective cost per spin. Scatter and bonus trigger symbols are usually listed separately at the bottom of the pay table screen.
What does a pay table tell you about a slot machine's RTP?
The pay table does not directly state RTP, but it gives you the building blocks to estimate it. By comparing the top symbol award relative to the minimum qualifying combination award, you can gauge how top-heavy the pay structure is. A game where the top award is 1,000x but the most common winning combo pays only 1x is high-volatility and likely has much of its RTP loaded into rare events. Games with flatter pay tables — where the top award is 100x and common combos pay 5x to 10x — tend to be lower volatility with more RTP returned on regular hits.
How do scatter pays appear in a pay table?
Scatter pays appear in their own section of the pay table, separate from line pays. They list the scatter symbol icon and the award for landing 2, 3, 4, or 5 scatters anywhere on the reels — not just on pay lines. Scatter pays are typically expressed as a multiplier of total bet rather than line bet. If the pay table shows 5 scatters paying 50x and you are playing $1 total bet, that is $50. Landing 3 or more scatters often also triggers the free spins or bonus round, which is noted alongside the scatter pay awards.
Can you calculate a slot machine's RTP from its pay table?
You can estimate RTP from a pay table but not calculate it precisely without knowing the reel strips (the probability of each symbol appearing on each reel position). The pay table gives you the award amounts. The reel strips give you the frequencies. Without both, you are estimating. However, comparing pay table award structures across similar games from the same manufacturer can give you useful relative comparisons. A game with significantly lower awards for the same symbol combinations than a comparable machine is likely returning less RTP.
What is the top symbol award in a slot pay table?
The top symbol award is the highest single-spin payout listed in the pay table, typically awarded for landing 5 of the highest-value symbol on an active pay line. On most modern video slots this is the game logo, a special icon, or a character from the theme. Top awards range from around 200x to 5,000x of the line bet on non-progressive machines. Very high top awards (2,500x and above) signal high volatility — most of the game's RTP is loaded into rare top-line hits rather than distributed across frequent small pays.
How do you spot a high-volatility slot machine from its pay table?
High-volatility slots have three pay table signatures: a large gap between the top award and second-tier awards (for example, 5,000x versus 200x), few or no pays for 2-of-a-kind combinations (meaning you need 3 or more matching symbols to win anything), and scatter/bonus trigger awards that are very small relative to the free spins or bonus round potential. When the pay table shows most of the value is concentrated in the top award and the bonus round, with little value in frequent base-game hits, you are looking at a high-volatility machine.
