Mermaid Riches

The reel structure in Mermaid Riches by PG Soft shifts mid-game: the base layout expands column by column (1-2-3-4-5 symbol rows), and free spins flip it into a mirror (5-4-3-2-1), completely reshaping where wins cluster. A Moving Wild drifts between positions between each cascade, while Countdown Wilds contribute to up to 3 wins before disappearing. With a 96.71% RTP, medium volatility, 20 paylines, and a top payout of 20,000x your bet, Mermaid Riches is one of PG Soft's more mechanically intricate ocean-themed slots.

What is Mermaid Riches?

Mermaid Riches is a 5-reel video slot from PG Soft with 20 paylines, a 96.71% RTP, medium volatility, and a max win of 20,000x your bet. Its reel structure is asymmetric, columns grow from 1 to 5 symbol rows left to right, creating a triangular grid rather than a standard rectangular one.

The two Wild types define the game's identity: a Moving Wild that repositions after each cascading win, and Countdown Wilds that stay active for a set number of wins before expiring. Both Wild types operate through a Cascading Wins mechanic where symbols explode on a win and new ones fall into place, potentially chaining into multiple consecutive payouts. In free spins, the grid flips to a 5-4-3-2-1 mirror layout and climbing multipliers (2x, 4x, 6x, up to 10x) apply to each cascade.

How To Play Mermaid Riches Slot - Step By Step

Head to Wild.io and create a free account to start playing Mermaid Riches.

1. Set your stake. Mermaid Riches uses 20 fixed paylines across the asymmetric 1-2-3-4-5 reel structure.
2. Spin. Winning symbol combinations pay left to right. After a win, the symbols explode and new ones drop in, this is Cascading Wins.
3. Watch the Moving Wild: after each cascade win sequence ends, the Wild moves to a new position on the grid before the next spin. It substitutes for all paying symbols and contributes to new line wins in its new position.
4. Countdown Wilds appear during play and stay active for up to 3 wins before expiring. They function identically to standard Wilds but disappear after their third contribution to a win.
5. Collect 3 or more Scatter symbols to trigger Free Spins. The grid flips to a 5-4-3-2-1 mirror layout and a climbing multiplier activates: 2x to start, rising to 4x, 6x, and up to 10x with each consecutive cascade win.

Mermaid Riches Slot Theme & Graphics

Mermaid Riches sets its action beneath a sunlit ocean surface, with light refracting through water casting shifting blues and greens across the asymmetric reel columns. The premium symbols, Pearl, Treasure Chest, and Golden Vase, are rendered as gleaming underwater artefacts rather than cartoon illustrations, giving the game a slightly more refined visual register than typical ocean slots. The marine creature mid-tier (Eel, Ray, Jellyfish, Starfish) adds biological accuracy alongside their decorative role.

PG Soft's asymmetric grid design is the real visual statement: the columns growing taller from left to right make the screen feel like a rising tide rather than a flat playing field. During free spins the flip to a 5-4-3-2-1 mirror creates an inverted-V shape, the tallest column is now in the centre rather than on the right, shifting the visual weight and the win clustering pattern simultaneously. On mobile, the portrait layout makes full use of vertical screen space for the taller left-side columns.

Mermaid Riches Slot Symbols & Paytables

Mermaid Riches runs three tiers of paying symbols across its asymmetric grid: high-value underwater treasures, medium-value sea creatures, and standard card ranks as the low tier. Two distinct Wild types operate alongside them.

Low Value Symbols

The low-value symbols are card ranks A, K, Q, and J, styled in flowing script font against underwater-lit backgrounds. They appear most often and fill the wider reel columns (columns 4 and 5 have 4 and 5 rows respectively), contributing to the frequent small wins that the medium volatility profile produces. In the asymmetric structure, low symbols in the taller columns create more payline possibilities by occupying more reel positions per column, a subtle mechanical advantage that makes the lower tier more active than in a standard rectangular grid.

High Value Symbols

The premium tier has three symbols: the Pearl at the top paying up to 150x for a full combination, the Treasure Chest in the middle range, and the Golden Vase at the entry-level premium. These values are per combination, so they reward the Cascading Wins mechanic well when the same premium symbol fills multiple positions across a chain. During free spins, the 10x multiplier at peak cascade depth significantly amplifies any premium combination on that single cascade hit.

Special Symbols

The Wild symbol comes in two forms. The Moving Wild is a standard substitute for all paying symbols, but after each cascade win sequence ends it moves to a new position before the next spin begins, this repositioning means it is never stranded in a non-winning location indefinitely. Countdown Wilds carry an internal counter: they participate in up to 3 wins before disappearing. Both Wild types contribute to Cascading Wins chains. The Scatter symbol appears anywhere on the grid and triggers Free Spins when 3 or more land in the same spin or across accumulated spins.

Mermaid Riches Bonus Feature & Special Features

Asymmetric Grid and Cascading Wins

Mermaid Riches plays on a 5-reel grid where each column has a different number of rows: column 1 has 1 row, column 2 has 2, column 3 has 3, column 4 has 4, and column 5 has 5. The 20 paylines run across the available positions on each column. When any win lands, the winning symbols are removed and new symbols cascade down to fill the gaps, following the column height logic. This can chain into multiple consecutive wins from a single paid spin, extending the value of one stake across multiple outcomes. The asymmetric structure means that more pay positions exist on the right side of the grid, influencing which symbol combinations are most likely to form.

Moving Wild and Countdown Wilds

Two Wild types give Mermaid Riches its tactical layer. The Moving Wild substitutes for all paying symbols and appears on the grid during play. After each complete cascade win sequence, it moves to a new position on the reels, this repositioning ensures it remains in play and relevant to subsequent spins rather than staying stuck in a low-value position. The Countdown Wild also substitutes for all paying symbols but carries a counter: it participates in up to 3 win events before it is removed from the grid. In practice this means a Countdown Wild can span multiple cascade chains across several spins, contributing to wins each time until its counter reaches zero.

Free Spins with Flipped Grid and Climbing Multiplier

Three or more Scatter symbols trigger the Free Spins feature. The grid immediately flips to a mirrored 5-4-3-2-1 structure, column 1 now has 5 rows and column 5 has 1, inverting the win-clustering pattern. A multiplier starts at 2x and increases by 2x with each consecutive cascade win within a single free spin sequence: 2x, 4x, 6x, up to 10x. The multiplier applies to each individual cascade win at its current value when that cascade resolves. Both Wild types remain active during free spins, and the new grid shape creates fresh payline configurations that may reward different symbol combinations compared to the base game layout.
