Why PG Soft slots use cluster pays instead of classic paylines

A pokies fan waiting for a tram down Flinders Street in Melbourne no longer has to settle for the same five-reel, line-based format that dominated Australian clubs for decades. The mobile screen in their palm now hosts grid-style games from studios like PG Soft, where wins form not along rigid lines but through clusters of matching symbols that vanish and tumble into fresh combinations. That shift from classic paylines to cluster pays is one of the most consequential design choices in modern online slot development, and PG Soft has built an entire library around it.

Cluster pays is a payout structure that rewards groups of adjacent matching symbols appearing anywhere on a game grid, typically requiring a minimum of five or six connected icons in any direction. Classic paylines, by contrast, demand that matching symbols line up from the leftmost column along predetermined paths, often twenty-five or fifty fixed lines across three to five reels. The cluster format removes the constraint of direction and position, opening the grid for chain reactions and overlapping wins on a single spin. Learn more about Dnabet Lotto.

PG Soft, sometimes called Pocket Games Soft, recognised early that mobile players in markets such as Sydney, Brisbane, and Perth wanted faster spin cycles, bigger symbol stacks, and more visual payoff per tap. Cluster pays deliver all three. Understanding why this format suits the studio's portfolio helps explain why so many of its releases feel closer to puzzle games than to the line-driven cabinets players still see inside Crown Melbourne or The Star Sydney.

How cluster pays actually work

A cluster win begins the moment the game engine detects a group of five or more matching symbols touching horizontally or vertically. The grid, often six rows by five or six columns, does not care where the cluster sits, only that the symbols form a connected block. Once the win is registered, the matching icons disappear, and the symbols above cascade into the empty spaces, with new symbols dropping in from the top of the grid.

That cascade mechanic, sometimes called a tumble feature, lets a single paid spin produce multiple wins in sequence. A player might land a cluster of eight high-paying symbols, watch them vanish, and then receive a fresh combination from the symbols that fall into place. PG Soft titles such as Mahjong Ways, Lucky Neko, and Wild Bandito lean heavily on this rolling payout rhythm, often chaining three or four cascades in a single round.

Multiplier systems frequently attach to the cascade feature, increasing the value of each successive tumble. A first cascade might pay at 1x, the second at 2x, the third at 3x, and so on. This progressive scaling creates a sense of momentum that fixed paylines cannot match, because every spin carries the possibility of a long cascade chain with an ever-growing multiplier attached.

Why PG Soft swapped lines for grids

PG Soft designs almost exclusively in portrait orientation, a deliberate choice that fits the way Australians hold their phones one-handed while commuting on Sydney trains or queuing for coffee in Adelaide. A vertical grid presents symbols at a comfortable thumb-reach, and a cluster-based layout removes the awkward horizontal tracking that line-based slots demand when players try to follow a winning combination across the screen.

The studio also built its user interface around tap, swipe, and hold gestures rather than the click-and-spin pattern of desktop-era slots. Cluster pays suit that gesture vocabulary because wins resolve quickly and clear the screen for new symbols, giving players an immediate sense of cause and effect. Each tap feels responsive, and each cascade feels earned, which extends session length in a way that slow-building payline combinations rarely do.

From a portfolio perspective, the cluster format lets PG Soft package Asian-themed art, multipliers, and free-spin bonuses into compact mobile experiences without overwhelming the grid. Games like Leprechaun Riches and Treasures of Aztec pack layered features into six-by-five layouts that would feel cluttered on a classic line-based machine. The studio has essentially optimised every design decision around a mobile, cluster-first audience.

The math driving cluster wins

Cluster payouts change the volatility profile of a slot in ways that line-based games rarely achieve. Because wins are not restricted to specific paths, the hit frequency tends to rise, meaning players see winning combinations more often. The trade-off is that individual cluster wins are usually smaller than long payline combinations, so the balance shifts toward frequent small payouts rather than rare large ones.

Return-to-player calculations also behave differently in cluster formats. With dozens or hundreds of ways for symbols to connect, designers must weight each symbol value against the larger grid. PG Soft typically publishes RTP figures in the ninety-six to ninety-seven percent range, with hit frequencies that land between twenty and thirty percent depending on the title. Reading a paytable closely reveals where the math comes from, and a paytable guide walks through the columns that matter most for cluster-style releases.

Volatility in PG Soft cluster games usually sits in the medium range, which appeals to Australian players who want bonus rounds and free spins to feel reachable without requiring a
