PG Soft Mahjong Ways: Cascade Grid with Building Multipliers Reviewed

Quick Facts: Mahjong Ways

Introduction

The four multiplier indicators above the reels are the game's central mechanical statement: x1, x2, x3, x5, each one a mahjong-style tile badge, with a gold ring marking the active step in a cascade chain. I tracked that ring advance through cascade sequences across 1,599 spins in the PG Soft provider demo - each successive winning step shifts the ring one position to the right, and the payout multiplier for that step climbs with it. That mechanic, layered over a Gold Plated tile-to-Wild conversion on reels 2 through 4, is what Mahjong Ways runs on.

Released in December 2019 as PG Soft's first mahjong-themed title, it established the cascade framework the studio would build out in sequels. RTP sits at 96.92% across multiple reference sources. What it delivers across 1,599 spins is documented below.

Note on RTP: the 96.92% figure is published by SlotCatalog, BigWinBoard, and additional aggregators. PG Soft does not publish RTP on their official game page. In any real-money casino, the actual RTP is operator-configured - always check the in-game information screen before playing for real money.

What Mahjong Ways Is

Mahjong Ways is a 5x4 cascade slot from PG Soft released in December 2019. It runs on a 1,024-ways structure - no traditional paylines, just any matching symbol combination landing on consecutive reels from left to right. The grid fills with mahjong-style tiles arranged in two tiers: four higher-value character tiles (發, 中, bamboo clusters, circular dot groups) and lower-value single-bamboo and single-circle tiles. Wild and Scatter symbols are present; there is no Buy Bonus and no Gamble option.

PG Soft built the game in portrait orientation. On a desktop browser the game area sits taller than wide - designed for a phone screen first, it plays on desktop without modification but the layout reflects its mobile origins. The "1024 WAYS" label sits in the wooden and bamboo frame header above the reels, visible from the first spin.

Bet range is listed across aggregators as $0.20 minimum to $50.00 maximum per spin. The in-game bet formula is bet_size x bet_level x 20 (the base-bet count for 1,024 ways), so exact steps depend on operator configuration.

Symbol Payout Values

From the in-game paytable (verified directly): the top-paying symbol is the green 發 (Fa) character tile at 100x for five of a kind. The red 中 (Zhong) tile pays 80x for five. Below that are the purple bamboo-frame tile at 60x and the red eight-bamboo tile at 40x. Lower-value tiles (circular dot clusters and single-bamboo) pay 20x and 10x respectively for five of a kind, with proportional reductions for 4-of-a-kind and 3-of-a-kind. Wild and Scatter symbols complete the set - Wild substitutes for all non-Scatter symbols, Scatter triggers the free spins feature.

How the Grid and Cascade Wins Work

1,024 ways means any matching symbol combination on three or more consecutive reels from the leftmost reel counts as a win, regardless of which row each symbol occupies. The game evaluates every valid left-to-right combination across all four rows simultaneously.

When symbols form a winning combination, they burst off the grid - a visual explosion effect fires at each winning position, gold coins scatter across the background as a win effect, and the remaining symbols fall down to fill the gaps. New symbols drop in from above. If the new arrangement produces another winning combination, the cascade continues. Each cascade step adds its payout to the total for that spin. The spin ends when no further winning combination forms.

Multiplier Bar and Gold Plated Wilds

All payouts within a cascade sequence are multiplied by the value on the active multiplier step. The sequence starts at x1. Any winning step advances the bar one position for the next step: x1 win produces a x2 next step, x2 win produces x3, x3 locks the bar at x5 for that step and every subsequent winning step in the same spin. The multiplier resets to x1 at the start of each new paid spin - it cannot carry forward between spins.

The Gold Plated mechanic adds a layer on top. Certain tiles on reels 2, 3, and 4 develop a golden frame during play. Any gold-framed tile that contributes to a cascade win in one step converts to a Wild at the start of the following step. The Wild then substitutes for any non-Scatter symbol in that next step, potentially extending the cascade and advancing the multiplier further. Gold Plated tiles appear exclusively on reels 2 through 4; reels 1 and 5 do not produce them.

I found myself tracking which tiles on reels 2-4 carried the gold frame at the start of each spin. A tile with a golden border signals that one winning cascade step can trigger a Wild conversion for the next step - the frame is visible and readable at standard play speed. On spins where two or three reels carried gold-framed tiles simultaneously, the Wild conversion pool for the next cascade step was deeper - more substitution coverage across reels 2-4 means more opportunities for the cascade to continue.

PG Soft does not publish an official volatility rating for this title. Based on 1,599 spins: medium. Seven bonus triggers, an approximately 18-spin longest dry stretch, and a 97.6x single-round result from a cascade chain are the session evidence for that classification.

Free Spins: Trigger and Payout Structure

Three or more Scatter tiles - the 胡 character (the Chinese "Hu" or "win" symbol) - landing anywhere on the grid triggers the free spins feature. The in-game rules specify 12 free spins for the minimum 3-Scatter trigger, with 2 additional spins per extra Scatter above 3. The feature can retrigger during free spins.

In free spins, the cascade multiplier bar doubles: x2 for the first winning step, x4 for the second, x6 for the third, x10 for the fourth and beyond. A cascade chain that reaches and sustains x10 in free spins pays out at twice the multiplier ceiling available in the base game.

The visual change when free spins trigger is immediate and unambiguous. The background shifts from the dark reddish-brown of the base game to a rich crimson environment with ornamental corner framing. The Scatter tiles themselves switch to a version carrying an orange-red flame animation - distinctly different from the ivory tile field of the base game. The shift from warm earth tones to saturated crimson is one of the clearest feature-entry signals in a PG Soft game of this era.

During free spins, a live countdown - "REMAINING FREE SPIN: N" - sits in a dark banner at the bottom center of the screen in large gold text, updating after each spin.

Seven free spins rounds triggered across 1,599 spins - roughly one trigger per 228 spins. Results varied considerably: weakest round returned 6.8x total from 15 spins; best round returned 186.4x from 27 spins. The spread captures the within-bonus variance - reaching x10 requires sustained cascades past the third step, which does not happen on every spin in a bonus round.

Session Results: 1,599 Spins

I ran 1,599 spins in the PG Soft provider demo (pg-demo.com), using virtual credits at a fixed bet throughout.

Bonus Breakdown

Seven free spins rounds across 1,599 spins - roughly one trigger per 228 spins in this session. The published average is around one per 204 spins, so this session ran slightly below that rate. All seven rounds, in the order they triggered:

Average across the seven rounds: roughly 74x. The weakest (6.8x, Round 1) was a cold start that never built the multiplier; the best (186.4x, Round 6) sustained cascades into the x10 step.

Two triggers came in rapid succession near spins 341 and 390 - just 49 spins apart - producing 95.8x and 116.0x respectively. Together those two rounds contributed the majority of the session's total bonus yield.

One caveat on those free-spin counts: the in-game rules award 12 free spins for 3 Scatters plus 2 for each additional Scatter - a pattern that only produces even totals (12, 14, 16...). Yet five of the seven rounds above are odd (15, 23, 23, 27, 19), which that rule cannot produce at all; only Rounds 4 and 5 (16, 18) fit it. No round retriggered this session, so retriggers do not explain the odd lengths either. So the printed base-plus-two rule does not account for most of the observed counts: either the demo's award behaves differently from that common description, or the capture read the free-spin counters imprecisely. I am reporting the observed figures and flagging the mismatch rather than smoothing it.

Session Progression

Session Peak: Biggest Single Spin

The session's largest single-spin result was 97.6x, and it landed inside a free-spins round rather than in base play. The frame below is from that round - the free-spins multiplier bar (x2/x4/x6/x10) and "REMAINING FREE SPIN: 6" are visible - but it captures a later cascade step (WIN 24.00), not the 97.6x spin itself. The Gold Plated Wild conversion on reels 2-4 combined with the climbing free-spins multiplier drove the cascade to 97.6x during that round.

Best Bonus Result

Test limitations: 1,599 spins is a meaningful demo session but not a sample large enough to reliably measure long-run return against the 96.92% published RTP. The session finished positive in virtual credits, which does not predict real-money outcomes. The observed return over these 1,599 spins was 140.9% (final balance 107,840.20 on 19,188 staked) - far above the 96.92% theoretical, which is what a short, hot sample looks like, not a sustainable rate. No retriggers occurred across the 7 free spins rounds. The 25,000x max win was not approached at any point in this session.

Bet Range and Bankroll Notes

Aggregators list the bet range as $0.20 minimum to $50.00 maximum per spin. PG Soft's own game page does not publish these numbers. The in-game bet structure uses a bet_size x bet_level x 20 formula - exact step increments depend on the operator's configuration.

For practical bankroll sizing: the free spins feature triggers approximately every 200-230 spins. A 500-bet buffer at the chosen stake covers around 2 to 2.5 expected trigger cycles (roughly 440-550 spins). At $0.20 per spin that is a $100 session fund; at $1.00 per spin it is $500. That figure is a planning buffer, not a guarantee. No Buy Bonus is available, so there is no direct-purchase path to the feature.

Pros and Cons

How Mahjong Ways Compares

Within the PG Soft Series

Mahjong Ways 2 (2021) built on this game's cascade framework with two significant additions: a Buy Bonus option and an enhanced scatter mechanic with higher free spin awards. The Buy Bonus costs roughly 100x the base bet for direct feature entry - a cost layer not present in Mahjong Ways 1. The core cascade-multiplier engine is structurally similar between the two titles; the key difference for practical play is whether direct feature access matters. For the same PG Soft cascade-multiplier mechanic without the buy option present, Mahjong Ways 1 runs the original version. Mahjong Ways 3 (2023) extended the series further with a larger grid and additional Wild mechanics. The three-title family shares the mahjong-tile aesthetic and cascade foundation; each adds layers not in the prior version.

Cross-Provider: Gates of Olympus (Pragmatic Play)

Both run cascade grids with building multiplier mechanics. Gates of Olympus multipliers stack from multiple multiplier orbs in the same spin; Mahjong Ways advances a fixed four-step bar. Gates of Olympus carries higher per-session variance. Mahjong Ways sits at the lower-volatility end of this comparison: medium classification, frequent cascade activity, and a multiplier ceiling of x10 in free spins vs Gates of Olympus' stacking multiplier structure at higher variance.
