Paylines, Ways and Clusters: Three Ways a Slot Decides You Won

The grid of symbols is only half the game. The other half is the rule that decides which arrangements count as a win, and there are three common ones.

Paylines

The classic system. A payline is a fixed path across the reels, and you win when matching symbols land along one, usually starting from the leftmost reel. Early machines had one line across the middle. Modern video slots may have dozens. General background on reels and lines is in Wikipedia's article on slot machines.

What to read in the rules: how many lines there are, whether all of them are always active, and how the bet is divided among them.

Ways to win

Here position on the reel does not matter. Matching symbols on adjacent reels, counted from the left, form a win wherever they sit. A five-reel grid with three rows gives 3 x 3 x 3 x 3 x 3 = 243 possible ways. Games that vary the number of rows on each spin can reach far higher counts.

A large number of ways sounds generous. It is not, in itself. The paytable is scaled to match, so individual wins tend to be smaller.

Cluster and pay-anywhere

Cluster games pay when a group of matching symbols touch each other, in any direction. Pay-anywhere games go one step further and simply count how many of a symbol are on the screen. Both usually come with cascading reels, covered in the note on cascades.

Why the difference matters to a player

• It changes what a "near miss" looks like, and so how the game feels.
• It changes how often small wins occur. Ways and cluster games tend to produce more frequent, smaller hits.
• It does not, taken alone, tell you anything about the long-run return. That is set separately.

The paytable states which system a game uses. If you are unsure how to read one, start with reading a paytable.
