Bust The Piggy Slot Review
Moonlight through an arched mansion window, coins spilling from a cracked-open cabinet, and one piggy bank parked on the grid hoarding everything it touches. Bust The Piggy is built on an unusual promise: the symbol doing all the work can’t pay you a thing, and the game is better for it. Every coin it swallows is deferred money, and the tension of waiting for the symbol that finally cracks it open is the whole point.
It’s a 6×5 grid from Backseat Gaming, paying through clusters of five or more connected symbols, running at 96.01% RTP with a 25,000x maximum win. The studio’s other titles, like De Rat Heist, Banana Farm and Fireborn, cover similar collector territory, but this one puts the entire payout structure in the piggy’s belly.
Everything here either feeds the bank or busts it, and the money doesn’t move until something forces it to.
Base Game & Features
Wins need at least five matching symbols connected horizontally or vertically, and the paytable is dynamic, shifting with the current bet amount. All pays are multiples of the total bet. The premiums climb steeply once clusters grow past a dozen symbols, which is where the grid’s tumble mechanics start to matter: winning symbols are destroyed, new ones drop in, and a single spin can chain several clusters together.
Symbols and Pays
Pays below are multiples of the total bet, by cluster size:
- Crown: 1.2x (5), 1.5x (6), 2.5x (7-8), 5x (9-10), 10x (11-12), 20x (13-14), 50x (15)
- Ring: 1x (5), 1.2x (6), 2x (7-8), 4x (9-10), 8x (11-12), 15x (13-14), 40x (15)
- Egg: 0.8x (5), 1x (6), 1.5x (7-8), 3x (9-10), 6x (11-12), 12x (13-14), 30x (15)
- Cash stack: 0.5x (5), 0.7x (6), 1.2x (7-8), 2.5x (9-10), 5x (11-12), 10x (13-14), 25x (15)
- K, A: 0.3x (5), 0.4x (6), 0.6x (7-8), 1.2x (9-10), 3x (11-12), 6x (13-14), 20x (15)
- 10, J, Q: 0.2x (5), 0.3x (6), 0.5x (7-8), 1x (9-10), 2.5x (11-12), 5x (13-14), 15x (15)
The Piggy Bank
The Piggy Bank is the game’s engine. It acts as a Wild, substituting for all paying symbols, and it’s stubborn: it doesn’t get destroyed after joining a win cluster, and it doesn’t tumble down when symbols beneath it are removed. It can land in all game modes.
Whenever a paying symbol wins alongside a Piggy Bank, its tile is highlighted. At the end of the spin, every highlighted square transforms into a Multiplier symbol or a Coin, and each piggy then collects the coins in its cluster. If several Piggy Banks share a cluster, each one collects every Coin separately, so overlapping piggies compound the same drop.
Coins are bet multipliers in four tiers, and the tier decides how much a single highlighted tile can be worth:
- Bronze: 1, 2, 3 or 4 times the bet
- Silver: 5, 10, 15 or 20 times the bet
- Gold: 25, 50 or 100 times the bet
- Diamond: 150, 250 or 500 times the bet
One catch shapes the whole game: Piggy Bank symbols don’t win anything on their own. Without a Trigger symbol, all that collected value just sits there.
Multiplier and Trigger Symbols
The Multiplier symbol boosts everything near it. It applies a random value to every Coin, or Piggy Bank holding collected values, in the eight tiles surrounding it, and the possible values are:
- 2x, applied to neighbouring Coins and loaded piggies
- 3x, same reach
- 5x, same reach
- 10x, same reach
A Multiplier sitting beside a Diamond coin is where the big swings live. Nothing about the symbol is choosy; it simply lifts whatever is next to it.
The Trigger symbol is the pay-out moment. When it lands, it collects the values from every Piggy Bank on the grid, all at once. It’s the only thing that turns hoarded coins into actual winnings, which makes it the symbol every other mechanic is arranged around.
Bust The Piggy Bonus Games & Free Spins
Three bonus games share one structure, and the Bonus symbol decides which one you get. One Bonus symbol can land per reel, and the thresholds are three, four or five. Every version awards 10 free spins with sticky Piggy Bank symbols and a guaranteed Piggy Bank on spin one.
Piggy Break
Land 3 Bonus symbols for Piggy Break. It’s the entry-level round: 10 free spins, sticky piggies, and their collected value resets after the trigger. Everything the banks gather during the round is what you’re playing for, and the sticky symbols mean a piggy that lands early stays useful for the duration.
Ride the Piggy
Land 4 Bonus symbols and the rules improve. Sticky Piggy Banks keep their value after the trigger instead of resetting, so the round starts from whatever was collected to get there. Four symbols is a harder ask, but you begin with a loaded bank.
Get Them Coins
Land 5 Bonus symbols for the top tier. Values don’t reset, and only silver, gold or diamond coins can appear, which removes the small bronze pays entirely. It’s the round the other two are practice for.
Retriggers and Upgrades
Bonus symbols keep working during the bonus games, and the retrigger ladder is where a good round becomes a great one:
- 2 Bonus symbols grant +2 free spins
- 3 Bonus symbols grant +4 free spins
- 4 Bonus symbols grant +4 free spins and upgrade the round to the next highest bonus level from the following spin
That upgrade matters more than the spins. A Piggy Break round that catches four Bonus symbols partway through becomes a Ride the Piggy round from the next spin, and a Get Them Coins round can only be reached by upgrading into it or triggering it directly.
Bonus Buys
Six buy options sit behind the CART button, and every one of them runs at the same 96.01% RTP as the base game. Wins evaluate at the base bet amount, and availability can vary by operator or jurisdiction. The prices step up sharply with the quality of the round:
- Bonus Boost Mode: 2x the bet
- Piggy Spins Mode: 30x the bet
- Double Piggy Spins Mode: 50x the bet
- Piggy Break: 100x the bet, an instant trigger
- Ride the Piggy: 300x the bet to trigger immediately
- Get Them Coins: 500x the bet and no waiting
Our Honest Verdict
Overall Rating: 7.8/10
Playing this one is a waiting game by design, and the reason to pick it is the same reason the heist theme fits so well: you’re in the mansion watching a number grow, and the payday only comes when somebody finally smashes the porcelain. When that Trigger lands, the payout is everything at once, and it’s a better rush than a dozen small cluster wins.
The bonus ladder is the cleverest part of the build. Three rounds with the same skeleton and progressively better rules means even the cheap trigger has a path to the top, which is more than most tiered bonuses offer. But the base game can feel like window-shopping: piggies stack value that pays nothing without a Trigger, and the cluster premiums stay small until you clear a dozen symbols at once.
It’s for players who like a build and a bust, not a steady drip of wins. If watching a counter climb without cashing it in sounds like frustration rather than fun, the mansion’s coins aren’t for you. For patient collectors, though, this vault is full.

Get Them Coins, from 5, keeps values and only deals silver, gold or diamond coins. -

It collects the values from all Piggy Bank symbols on the grid. Because Piggy Banks don’t win anything on their own, the Trigger is the only symbol that turns their collected coins into an actual payout.
