Start with the return figure, not the pictures
Most players scroll straight to the symbol artwork, yet the single most useful number on any paytable sits quietly near the top or bottom of the screen. That figure is the return to player percentage, usually written as RTP, and it tells you how much of all staked money a slot pays back over millions of spins.

In the United Kingdom, licensed operators must publish this information, so it is never hidden. A typical online slot returns between 94% and 96.5%, with anything below 94% worth a second thought. Some titles run at 97% or higher, and a handful of promotional games sit closer to 92%.
The gap looks tiny but compounds fast. On £100 of spins at 96%, the expected loss is £4. At 92%, it is £8. Check this number first, then read on.
Paytables occasionally list several RTP values depending on stake or bonus buy options, so confirm you are reading the figure that applies to the way you intend to play.
Locate the win lines and the wild rules
Next, find the payline diagram. Slots usually state how many lines are active and whether wins pay left to right, right to left, or both. Cluster-pay and “any adjacent” games work differently, and mixing them up leads to confusion mid-session.
Look for the wild symbol and its exact job. A standard wild substitutes for all regular symbols, but many titles add multipliers, expanding behaviour, or restrictions. Some paytables note that wilds do not substitute for scatters, which matters when chasing bonus triggers.
Then scan the scatter. Its rules sit apart: scatter wins typically pay in any position, and three or more usually start free spins. The paytable should state the trigger count and whether the feature can be retriggered.
- Paylines active and direction of pay
- Wild substitutions and any multiplier
- Scatter trigger requirements
- Maximum win cap, often 5,000x to 50,000x stake
That max win cap is easy to miss. It can be written in small print at the base of the table, and it decides how much of a jackpot is genuinely reachable.
Decode the symbol values in seconds
Symbol tables are ordered by value, highest at the top. Read the top three rows and you have the shape of the game. For example, the premium symbol might pay 50x stake for five of a kind, with the lowest card symbol paying 0.5x.
Compare those figures against the stake selector. A win of 25 coins sounds generous until you notice each coin equals £0.01, making it £0.25. Always check whether values are shown in coins, credits, or pounds.
Finally, glance at any special mechanics listed alongside the symbols: cascading reels, symbol upgrades, or collection meters. These change how often the top prizes actually land.

Two minutes of reading saves far longer than two minutes of guessing.
