Piggy Wheel Bonanza Slot Review
A cartoon farm stretches out behind the reels of Piggy Wheel Bonanza: green pasture, a red barn, hay bales sitting in the grass, and the lower arc of a giant carnival wheel rising over the top of the grid with a gold pointer tucked beneath it. That wheel is doing more than the storybook art lets on. It decides which of four very different bonuses you get, and it’s the rare game where landing the trigger is only half the moment.
Dragon Gaming have built a 5×4 grid that pays across 243 ways, running at 94.11% RTP with a win cap of 10,000x the bet. The bonus build is what makes it worth a look, and there’s more than one way into it. Sister title Plundering Pirates Hold And Win covers similar ground for this studio.
Base Game & Features
The main game plays out on a 5×4 grid with 243 ways to win. There are no paylines to follow: matching symbols on adjacent reels from the left count as a win, wherever they sit on those reels. Each game costs 20 fixed coins, and ways-pay wins are multiplied by coin value.
All symbols pay from left to right in consecutive order, and only the highest win in a winning combination is paid. Where several ways hit on the same spin, each one pays its own value rather than being absorbed into the biggest.
Two symbols do the feature work. The Special symbol triggers the Bonus Game when six or more land on the reels. The Scatter triggers the Feature Wheel when three or more appear, with the wheel starting after line wins are paid.
There’s also a Random Bonus. When it activates, three Scatter symbols appear on screen and the feature game starts from there, no scatter alignment required. It’s the only route into the wheel that doesn’t depend on what lands.
Wild Symbol
The wild is a wolf character that stands in for every symbol except the Special, the Scatter and the Feature Wheel symbols. It doesn’t help build either feature trigger, only line wins.
Piggy Wheel Bonanza Bonus Features
Bonus Game
Six or more Special symbols trigger the Bonus Game. Every cell containing a Special symbol upgrades to STRAW (T1), and the round starts with six free spins. Each spin, a Special symbol that lands either becomes a new STRAW cell or upgrades an existing cell to the next tier: WOOD (T2), then BRICK (T3).
When a Special symbol lands on a cell that’s already BRICK, another random cell becomes BRICK instead. That’s the only way the grid keeps filling once a cell has maxed out, and it means late-round Special symbols are never wasted.
The round ends when no more BRICK cells can be created, or when every cell is BRICK. At that point the marked cells pay out, each worth its tier’s win value from the tier win table. A full grid of BRICK is the round’s ceiling, and the two end conditions pay out identically once the table is read.
Three or more Special symbols during the round award extra free spins, at one or more per hit, building to a maximum of 15. With six spins at the start, that leaves nine retriggers’ worth of room for a round that keeps feeding the grid. The same retrigger applies in every wheel-triggered bonus variant below.
Feature Wheel
Land the scatters and the wheel does the rest. It carries seven segments: three feature bonuses and four jackpots, listed below.
- Jumbo Hat Bonus
- Rolling Wheel Bonus
- Brick House Bonus
- Grand Jackpot
- Major Jackpot
- Minor Jackpot
- Mini Jackpot
Jumbo Hat Bonus
This one opens with a spin that drops a big Special symbol onto the reels, sized 2×2, 3×3, 3×5, or two 2×2 blocks. Every position it covers starts the free spins round already marked as a STRAW cell, with six free spins awarded.
From there it plays like the standard Bonus Game: new Special symbols mark or upgrade cells, three or more add a spin up to the 15 cap, and the marked grid pays out when the round ends. The bigger the opening block, the more of the grid starts working for you.
Rolling Wheel Bonus
Here the Scatter symbols roll to the right, one reel at a time, turning each position they pass through into a STRAW cell. Special symbols in the way upgrade to WOOD, and existing WOOD cells upgrade to BRICK. The free spins round then runs with those marked cells in place, capped at 15 spins.
Because a scatter rolling across a full row leaves a trail of STRAW behind it, the starting grid here tends to be wider than the plain Bonus Game’s, while the upgrade-on-contact rule can hand out BRICK cells before a single free spin has played.
Brick House Bonus
The most direct of the three. Every Scatter and Special symbol is marked as a BRICK cell from the off, and any new Special symbol that lands becomes BRICK too. When a BRICK cell already exists, one random unmarked cell turns BRICK.
Fill the grid and the round ends with all prizes revealed. Of the three wheel features, this one trades the slow tier climb for top-value cells from the first spin.
Jackpots
Landing on a jackpot segment pays immediately, at a fixed multiple of the total bet. The values don’t scale with anything but the stake, so they’re the same proportion whatever you’re spinning at.
- Grand Jackpot – 2500x total bet
- Major Jackpot – 500x total bet
- Minor Jackpot – 60x total bet
- Mini Jackpot – 12x total bet
Bonus Buy
Both features can be bought outright, at a stiff premium for the wheel. Neither buy carries its own published return figure, so the base game’s 94.11% is the only number on the table.
- Bonus Game – 100x total bet
- Feature Wheel Game – 200x total bet
Our Honest Verdict
Overall Rating: 7.2/10
This is a game about building something, which suits the farmyard better than it has any right to. Watching straw turn to wood and wood to brick, spin by spin, gives every bonus round a shape most free-spins games don’t have, and that slow accumulation is the reason to pick it up.
Its best idea is the wheel itself. Because each segment starts the round differently, the trigger never feels like a rerun, and the Brick House path can hand you a grid already loaded with top-tier cells before a single free spin plays.
The payback is the weak spot: 94.11% sits below the modern standard, and the 200x wheel buy asks a lot on top of it. For players who enjoy a long build and a bonus round that rewards patience, the pigs have built something solid here. Anyone weighing every decimal of return will find the maths on the thin side.
