3 Piggies of Bank Slot Review
Three storybook houses perch above the reels, a crossed-out wolf head warns nobody off, and a wooden sign along the bottom of the frame tells you to “Fill your BANK with money!” 3 Piggies of Bank is a game where almost nothing happens on the reels themselves: the base paytable is thin, the wins are small, and every interesting thing about it has been pushed into one coin-driven bonus round. The farm dressing is charming, but the pigs are really running a single-feature operation.
The charm is doing real work, because this is a quiet, low-volatility build from Yggdrasil: a 5×3 grid and 25 fixed paylines. The maths is gentler than the wolf on that signpost would suggest.
Base Game & Features
Play runs left to right across 25 fixed paylines on a 5×3 grid, with only the highest winning combination on each line counting. Low volatility shapes everything here: wins land often and tend to be small, which suits longer sessions on a modest stake. Roughly a quarter of spins produce a hit, at a stated frequency of 25.2%. The symbols split into two tiers:
- Premium symbols: Vault/Safe, Gold, Silver and Cash, carrying the banking theme
- Royal symbols: Heart, Diamond, Club and Spade, all sharing one row of values
Symbols and Pays
The paytable is a flat ladder, with every value a multiple of your line bet:
- Vault/Safe: 0.8x / 3x / 15x for three, four or five
- Gold: 0.5x / 2x / 10x
- Silver: 0.4x / 1.6x / 8x
- Cash: 0.3x / 1.2x / 6x
- Heart, Diamond, Club, Spade: 0.2x / 0.4x / 2x
It’s a compressed ladder, too. The step from four to five matching Vaults is five times the size of the step from three to four, and the royals never pay more than 2x for a full line. Line wins are pocket money; the real currency of this game is coins.
There’s no maximum win figure for this one. The four fixed prizes in the bonus game are the closest thing to a ceiling.
Mamma Pig Wild
The Mamma Pig wild substitutes for all standard symbols and appears in both the base game and the free spins. It can’t expand over Scatter or Free Spin symbols. After all symbols land, it may randomly expand, with the multiplier tied to how far it grows:
- Single (no expansion): 1x
- Double (two-row expansion): 2x
- Full (three-row expansion, its maximum size): 3x
Because the expansion resolves after every symbol has landed, a single spin can turn a modest line win into something meatier when Mamma Pig decides to stretch. The expansion is random rather than guaranteed, which keeps it a surprise rather than a strategy.
Coins and the Houses
Alongside the wild, two coin symbols drive the action. Wolf Coins and Piggie Coins can land on the reels in both the base game and the free spins, and they’re the route into the bonus game. There’s a neat bit of theme in that: the wolf and the pigs both feed the same round, which is about as close as this fable gets to a happy ending.
Three houses sit at the top of the reels through every spin, labelled Double, Mystery and Collect. They’re not decoration; they mark which of the bonus game’s three outcomes is in play, and each one plays differently when the round fires.
3 Piggies of Bank Free Spins and Lock’em & Load’em Bonus
Free Spins
The Blow it Down scatter lands only on reels 1, 3 and 5, and hitting all three opens the Free Spins feature. The round is retriggerable: the scatter can appear again during the feature, adding further spins to whatever remains. Because the scatters sit on the outer reels and the middle one, they can never land adjacent, which makes the trigger a genuinely distinct event from a normal win.
During the free spins, both the Mamma Pig wild and the two coin symbols stay live. That’s what gives the round its depth: you’re not only collecting spins, you’re still building towards the Lock’em & Load’em bonus while the wild’s expansion multipliers are in play. A lucky run can stack the two features in a single session of the feature, which is where the game’s better outcomes live.
Lock’em & Load’em Bonus Game
The coins are the key to the Lock’em & Load’em Bonus Game, which can fire from the base game or from within the free spins. It’s the game’s set-piece round, and it carries the whole prize structure:
- Trigger: Wolf Coin and Piggie Coin symbols landing on the reels
- House awards: Collect, Double or Mystery
- Fixed prizes: Grand, Major, Minor and Mini, all winnable during the round
The Double house is where the round becomes a proper event. The reels give way to a separate board of six coin positions, each carrying a multiplier, and the aim is spelled out plainly: fill the board with coins to win the Grand. Leave a position empty and the round ends short of it. A counter tracks how close you are to the full board.
The multipliers on those coins vary, and the spread matters. Values seen on the board include 8x, 6x, 4x, 7x and 1x, so the difference between a full board and a near miss isn’t just the Grand prize; it’s also how much each individual coin contributes along the way.
The Mystery and Collect houses are the other two possible awards, each shown on its house at the top of the reels. Which of the three you get isn’t chosen in advance; the outcome is decided when the bonus game fires, and the houses spend the base game displaying the three possibilities.
Bonus Buy
A BUY button sits bottom-right of the base game screen, so the feature can be purchased outright rather than waited for. That skips straight to the bonus action, at the cost of the organic build-up the coin symbols otherwise provide. In a game this gentle, the wait is part of the design, so the buy button is there for the impatient rather than the impatient being an afterthought.
Our Honest Verdict
Overall Rating: 7/10
Most of your time in 3 Piggies of Bank is spent watching a pretty farm valley hand you small change, and the reason to sit through that is the Lock’em & Load’em round. Everything converges on it: the coins, the houses above the reels, the four fixed prizes. The storybook dressing makes the waiting easy company, which matters in a low-volatility game.
The Double board is the best thing here, because filling it is the only moment the game builds genuine tension. The weakness is the base game itself: a quarter of spins pay something, but a full house of five Vaults returns just 15x, so line wins never feel like the point.
It suits players who like a slow build towards one set-piece, on a stake that lasts. Anyone hunting a ceiling or a big base-game hit won’t find one, and the valley will feel slow. For the rest, it’s an easy, cheerful place to graze.
