Piggy Riches 3: Hog Heaven Slot Overview

Piggy Riches 3: Hog Heaven is the latest entry in the long-running Piggy Riches series, and this time NetEnt has taken the reins back from Red Tiger. Played on a 5x3 grid with 20 paylines, it takes you inside the lavish mansion of Mr. and Mrs. Piggy. High volatility, 96.06% RTP, and a max win of 10,387x. Not bad on paper.

I quite liked that NetEnt went a different direction with this one. Rather than another Megaways version, you get Walking Wild Re-Spins in the base game and a proper collector-style bonus round set up in the clouds. Bets run from 20p to 40 quid a spin, and there are five Elevate bonus buy options if you fancy skipping ahead. Visually, the game looks proper polished; golden everything, red carpets, giant piggy statues.

Symbols and Paytable

Low pays are the usual 10 through A card ranks, worth 0.75x to 2.5x for a five-of-a-kind line. Premium symbols include bags of gold, champagne bottles, gold bars, and diamonds, paying between 5x and 30x for five on a line. Mr. Piggy and Mrs. Piggy act as the wild symbols and pay the same as the diamond at 30x for five. They substitute for everything except the Golden Pig Scatter.

During Free Spins, the reels swap over to special symbols only. You get Coins worth 2.5x to 50x, Pearls worth 1.25x to 25x, and Jackpot symbols that can be worth 1,000x, 2,000x, or even 5,000x the bet. There are also +3 spins symbols, x1 multiplier boosters, Level Up symbols, and a Mystery Wheel. Loads going on in there.

Piggy Riches 3: Hog Heaven Slot Features

Mr. Piggy and Mrs. Piggy wilds are the main draw in the base game. When either lands, Walking Wild Re-Spins kick in. Mr. Piggy walks right, Mrs. Piggy walks left, one position per respin, until they leave the grid. Each wild starts with an x1 multiplier that goes up by one every time it helps form a win. Decent mechanic for building up small payouts over several spins.

Here is where it gets interesting. When both pigs land on the same row and collide, they merge into a colossal wild; 3x3 if they meet in the middle row, 3x2 at top or bottom. The colossal wild then moves randomly left or right. I will say, from what I have seen, it seems to head right more often than you would like. A leftward move tends to link more wins, so that can be a bit frustrating.

Land the Golden Pig Scatter and you trigger 10 Free Spins on an expanded 5x5 grid. A 2x2 collector frame spawns in the bottom-left corner and chases Pearl symbols around the reels. Collect 5 Pearls and the frame grows to 3x3 with +2 extra spins; 9 Pearls makes it 4x4 with +3 spins; 12 Pearls hits 5x5 with +4 spins. There is also a multiplier counter that goes up to x10, and a Mystery Wheel that can award multipliers, extra spins, Level Ups, or Coins. The Elevate menu lets you buy features from 5x the bet (boosted scatter chance) all the way up to 500x (free spins with x5 multiplier plus a guaranteed collision after). Fair warning though; watching prizes land just outside your collector frame is properly annoying.

Volatility, RTP and Max Win

RTP sits at 96.06% at the top config, which is about average. Be aware that operators can set lower RTP versions down to 88.08%, so always check before you play. Hit frequency is 23%, which is actually quite good for a high-volatility slot. You will not go too many spins without something landing, even if many of those hits are small card rank wins.

Max win is 10,387x your bet. Not the biggest ceiling I have seen on a high-volatility game, but decent enough. Getting there likely means a strong Free Spins round with a full 5x5 collector, stacked multipliers, and a Jackpot symbol or two landing inside the frame. Not something you will see often, but the potential is there.

Ryan Cole’s Verdict

Piggy Riches 3: Hog Heaven Slot Verdict

NetEnt has done a decent job bringing the Piggy Riches series back without just copying what Red Tiger did with the Megaways versions. Piggy Riches 3: Hog Heaven looks great, the mansion interior is proper swanky, and the animations are smooth. The Walking Wild Re-Spins keep the base game from going stale, and the collector bonus round is something genuinely different for this series.

My gripe is that the colossal wild walks off to the right a lot, and the collector frame in free spins can be maddening when prizes land just outside it. Also, fans of the older games might miss features like Cascading Reels and Expanded Wilds that have been dropped. Still, for a casual session with a bit of variety and some proper big win potential, it is a fun spin. I would not call it the best slot of the year, but if you liked the original Piggy Riches, give this one a go.

Piggy Riches 3: Hog Heaven FAQ
How do the Walking Wild Re-Spins work in Piggy Riches 3: Hog Heaven?
When Mr. Piggy or Mrs. Piggy Wild lands on the reels, re-spins begin. Mr. Piggy moves one position to the right each respin, Mrs. Piggy moves left. Each wild carries a multiplier starting at x1 that increases by +1 for every win it contributes to. Re-spins continue until all wilds leave the grid.
What happens when Mr. Piggy and Mrs. Piggy collide on the same row?
They merge into a colossal wild symbol. It is 3x3 if the collision happens on the middle row, or 3x2 if at the top or bottom. The colossal wild then moves randomly left or right each respin until it exits the reels. Their individual multipliers are added together.
How does the collector frame work during Free Spins?
A 2x2 colossal collecting symbol starts in the bottom-left corner of the 5x5 grid. When a Pearl lands, the frame moves to collect it along with any other symbols inside its borders. Collecting 5, 9, or 12 Pearls expands the frame to 3x3, 4x4, and 5x5 respectively, and awards extra free spins each time.
What are the Elevate bonus buy options and their costs?
There are five tiers. Golden Pig at 5x boosts scatter chance. Walking Wild Re-Spins at 10x guarantees wilds. Colliding Wilds at 30x guarantees a collision. Free Spins at 100x triggers the bonus directly. Free Spins and Collide at 500x gives free spins with an x5 multiplier plus a guaranteed collision afterwards.
How big are the Jackpot symbols during Free Spins?
Jackpot symbols can appear with values of 1,000x, 2,000x, or 5,000x the bet. They are multiplied by any active multiplier before being collected by the colossal frame, so with a high multiplier counter they can contribute huge amounts to your total.
