The paytable is part of the design

Clear rules explain the relationship between symbols, outcomes and changes of state.

Start with the explanation

A slot’s artwork is only one layer of its design. Its rules and paytable explain which outcomes count, how they are evaluated and what they award. The Gambling Commission in Great Britain’s remote standards require understandable rules to be readily available before a customer commits to gambling within the standard’s scope.

Follow a change of state

A game may use different conditions during a feature. An effective explanation makes the current state clear instead of asking readers to infer it from a new background or soundtrack. The same guidance discusses displaying collected symbols and indicating which rules currently apply. Those details help connect the screen’s appearance to its underlying structure.

Read critically

When analyzing a game, identify the symbols, the conditions for an outcome and any clearly described exceptions. If a rule remains ambiguous, the interface has left an explanatory gap. This is an exercise in understanding a designed system, not a strategy for beating it. A legible paytable can explain a game’s terms without making its results predictable.
