Layout and evaluation
Distinguish the number of reels and rows from the way winning symbols are evaluated. A similar-looking grid may use a different system.
A slot’s identity comes from more than its theme. Layout, symbol evaluation and feature triggers determine how its explanation should be read, with Starburst providing one specific example.

Reels and visible rows describe the playing area, while a payline describes a defined route used to evaluate symbols. A picture showing several matching symbols does not alone tell you how they are counted. The exact game’s rules connect appearance with evaluation.
Special symbols also need an exact role. A Wild may substitute for other symbols, but the applicable conditions belong to the individual title. A Scatter, bonus symbol or feature trigger should not be treated as another name for the same mechanism.
Starburst is a useful named case because its expanding Wild is linked to a Respin. A different kind of comparison is a slot with a separately triggered free-spin feature. The trigger, duration and end condition must be read for that title rather than borrowed from Starburst.
Compare mechanisms one at a time, using the rules that belong to each exact game.
Distinguish the number of reels and rows from the way winning symbols are evaluated. A similar-looking grid may use a different system.
Ask whether the symbol substitutes, triggers an event or does something else. Its colour or size does not establish the rule.
Identify how a feature starts, what happens during it and what brings it to an end. Separate a Respin from a free-spin feature.

NetEnt’s original Starburst uses five reels, three rows and ten paylines. Its Starburst Wild expands across a reel, substitutes for paying symbols and triggers a Respin. These details explain the relationship between the layout and the special event.
The dedicated page follows that event in order and separates the main feature from its theme. The image here is a casino concept illustration; a game’s own paytable remains the place to identify exact symbol values and combinations.
Distinguish the original game from sequels or similarly named versions.
Read the paytable together with the visible layout.
Trace the stated trigger, feature behaviour and finish.
No. Evaluation follows the exact title’s rules, which may depend on paylines or another specified system.
The general idea is substitution, but the conditions and additional effects depend on the game.
They are different feature descriptions. Read how each is triggered and what rules apply during it.
Starburst by NetEnt has its own page covering the five-reel layout, expanding Wild and Respin relationship.
