Introduction to Mermaids Millions Cashingo
Mermaids Millions Cashingo is a casino slot from Stormcraft Studios with the Cashingo Feature, which we have seen in a couple of games from the sister studio SlingShot Studios. Apart from the regular reels, you will also find the Cashingo grid to the left, where cash symbols can land. The Cashingo grid is like a bingo card, where you’re awarded cash prizes whenever you fill a bingo line.
Mermaids Millions Cashingo has an underwater theme, with a male mermaid as the highest-paying symbol, and a female mermaid as the Wild Symbol. There are also several bonus games stuffed into this release. Let’s have a closer look at it.
If you want to try out the game yourself, you can play the free demo at the top of this review.

Theme, Gameplay, and Payouts
Mermaids Millions Cashingo is a video slot from Stormcraft Studios with 5 reels, 5 rows, and 40 paylines. The Min.bet is 0.2, and the Max.bet is 20. The game’s RTP is 96%, and the volatility is very high. Mermaids Millions Cashingo has a max win of 13,282x the bet, and the hit frequency of 34.33% means that about every third spin is a winner.
The game takes us to an underwater world. The scene looks very natural with a sandy bottom and colorful corals. Some bubbles travel upwards, but there are no fish visible. The reels are a bit to the right to make room for the Cashingo grid to the left, consisting of 25 bubbles in a square. At the top of the screen are the Jackpot prizes, with the 5,000x Grand Jackpot enticing us. To make a win, you need to land 3 or more matching symbols in one of the 40 paylines, starting on the first reel to the left. The game is available on mobile phones, tablets, and desktop computers.
The lower-paying symbols in Mermaids Millions Cashingo are green, blue, orange, and purple gemstones. They pay between 1.6x and 1.8x the bet for wins of 5 symbols. The higher-paying symbols are dolphins, anchors, boats, treasure chests, male, and star fish. They will give you between 2.5x and 20x the bet for a win containing 5 symbols. The Wild Symbol substitutes all mentioned symbols in making payline wins, but it doesn’t substitute Scatter and Coin Symbols.
Special Features & Slot Mechanics

What features are available in the slot Mermaids Millions Cashingo?
The features are Wild Symbol, Power Stacks Feature, Hot Mode Feature, Cashingo Feature, Ultra Link&Win Feature, Free Spins, and Feature Buy.

Wild Symbol
The Wild Symbol can replace most other symbols to help create winning combinations. It does not substitute for the Scatter or Coin symbols. It can appear in the base game and the Free Spins.
Power Stacks Feature
The Power Stacks feature is active on every spin in both the base game and Free Spins. Symbols may be randomly Power Stacked and then added across all reels. In the base game, all symbols except Scatters, Wilds, and Coins can be Power Stacked. During Free Spins, only Wild and Coin symbols are eligible for Power Stacking.
Hot Mode Feature
The Hot Mode feature can randomly activate during the base game. When triggered, a free Coin symbol is awarded and held in the Coin collect meter. This also reduces the number of Coins needed to grow the Ultra Link&Win meter or trigger the Ultra Link&Win feature. While Hot Mode is active, landing five or more Coin symbols in the base game will directly trigger the Ultra Link&Win feature, while landing 3 or 4 Coins will contribute to filling the meter.
The feature ends after a random number of spins, when Ultra Link&Win or Free Spins are triggered, or if the Ultra Link&Win feature is purchased.
Cashingo Feature
During the base game and Free Spins, landing Cashingo Cash and Jackpot Coins will fill positions on the Cashingo grid, positioned to the left of the slot’s reels. Any Cashingo Coins that appear on the reels are transferred to their matching positions on the grid. If a Cashingo Cash Coin already exists in that position, its cash value is added to the existing one. Completing a horizontal, vertical, or corner-to-corner diagonal line of Cashingo Coin symbols awards a cash prize, with up to four sets possible on a single spin.
If sets intersect, the shared Cashingo Cash Coin contributes its value to one completed set. Only Cashingo Coins that form part of a winning set are removed from the grid. Completing a set that includes one or more Cashingo Jackpot Coins awards the corresponding jackpot. At any time, only one of each Grand, Major, Minor, and Mini Cashingo Jackpot Coin can appear on the grid.
Each Cashingo Cash Coin shows a random cash value between 0.5x and 12x. The Grand jackpot pays 5,000x, the Major 500x, the Minor 50x, and the Mini 15x the bet. The feature can trigger during both the base game and Free Spins.
Ultra Link&Win Feature
The Ultra Link&Win feature is triggered when 6 or more Coin symbols land anywhere on the reels. When activated, 3 respins are awarded. The triggering Coins remain locked in place while the other positions respin. Any new Coins that land are also held and reset the respin count back to 3. You can only land Cash, Jackpot, Booster Coins, and blank positions. Wins are added to base game wins, and the feature ends when no respins remain or all positions are filled.
Landing 4 or 5 Coins in the base game or Free Spins contributes to filling the Ultra Link&Win meter. Once the meter reaches the required level, the next Ultra Link&Win feature will trigger in either Max Mode, Multiplier Mode, or Collect Mode.
Max Mode starts with 3 additional rows active. Multiplier Mode also starts with all 3 extra rows and guarantees a Persistent 2x Multiplier Ultra Link&Win Booster Coin. Collect Mode begins with all 3 extra rows active and guarantees a Persistent Cash Collect Ultra Link&Win Booster Coin. Triggering Collect Mode empties the Ultra Link&Win meter.
Only one of each jackpot Coin can land during the feature. Jackpot Coins count down once per spin and are paid if their countdown finishes before the feature ends. Booster Coins add extra effects during the feature. The Persistent Cash Collect Booster Coin gathers the total value of all Cash Collect Booster Coins and Cash Coins on every spin and retriggers until the feature ends.
The Persistent 2x Multiplier Booster Coin randomly doubles up to four Cash Coins on every spin and retriggers until the feature ends, while standard 2x Multiplier Booster Coins apply only to the current spin. Jackpot values cannot be doubled by any multiplier. The Unlock Booster Coins activate extra rows, with up to three additional rows available. Extra Chance Booster Coins award one extra respin and activate when no respins remain.
The feature can trigger in both the base game and Free Spins. The Cashingo Feature or the Free Spins cannot trigger at the same time as this feature.
Free Spins
Landing 3, 4, or 5 Scatter symbols anywhere on the reels triggers 10 Free Spins and pays 1x, 5x, and 20x the bet. All Wild and Coin symbols are Power Stacked on every spin during the feature. Free Spins cannot be retriggered. If a Cashingo win occurs at the same time Free Spins are triggered, the Cashingo win is paid before Free Spins begin.

Feature Buy
The Feature Buy option is available in the base game only and cannot be used above a certain bet level. Activating this option instantly triggers one of the Ultra Link&Win features. The standard Ultra Link&Win feature costs 50x the bet. Max Mode costs 95x the bet and starts with all 3 additional rows active. Multiplier Mode costs 120x the bet, starts with all extra rows active, and guarantees a Persistent 2x Multiplier Booster Coin. Collect Mode costs 200x the bet, starts with all extra rows active, and guarantees a Persistent Cash Collect Booster Coin.
Final Thoughts on Mermaids Millions Cashingo
Mermaids Millions Cashingo tries very hard to look busy, and to be fair, it succeeds. There are meters filling up, grids lighting up, coins flying around, and jackpots staring at you from the top of the screen like they’re judging your life choices. On paper, this sounds exciting. In practice, it feels a bit like watching the same underwater episode on repeat. The theme is pleasant enough, but it doesn’t exactly scream originality, and the mermaids won’t be winning any personality contests anytime soon.
The biggest issue is that this slot is a so-called re-skin. If you’ve played Eruption Blaze Cashingo, you already know this game almost inside out. The mechanics, features, and overall flow are identical, just with lava swapped for bubbles and corals. It makes the whole experience feel slightly recycled, like leftovers that were reheated and sprinkled with some seashells.
Gameplay-wise, there’s plenty happening, but wins can be stubborn, and the very high volatility means that long dry spells can be part of the deal. We’ve got to say that the hit frequency of 34.33% is higher than normal for such a game.
Mermaids Millions Cashingo from Stormcraft Studios feels like a safe, average slot that swims comfortably in the middle of the pack rather than standing out from the ocean of similar games.
