Piggy Riches Slot Review

Piggy Riches is a 5-reel, 3-row video slot by NetEnt built around a pair of lavishly dressed pigs living in a country mansion surrounded by stacks of cash. Released back in 2010, it remains one of the studio's most recognisable titles thanks to its clickable Scatter Free Spins menu, Wild multipliers and a paytable stuffed with money bags, gold cards and diamond-encrusted royals.

The game runs on 15 fixed bet lines and pays from the leftmost reel to the right, with wins multiplied by any Wilds that take part in the combination. Medium volatility and a hit rate of around 34% make rounds feel active, while the top theoretical payout reaches 2,400x the total bet.

Gameplay and interface

The layout is deliberately simple. Reels sit inside a gilded frame, flanked by two columns of dollar-bill icons that mark the 15 active lines. Along the bottom panel you will find the Bet selector, a large green "Spin" button, "Autoplay" and the speed-up control. The help menu is reached through the "?" icon in the top-right corner, where "Game Basics", "Paytable" and "Return to Player" sections are listed.

A single spin at R1 runs across all 15 lines by default — bet size changes apply to every line at once, so there is no need to juggle coin values separately. Wins are paid out left-to-right on consecutive reels, and only the highest combination on each line is counted.

Symbols and payouts

Piggy Riches splits its symbol set into two clear groups. The low-paying icons are the jewel-studded royals 10, J, Q, K and A, each decorated to match the opulent theme. The premium group features a pink piggy bank, purple wallet, pig-shaped key ring, gold Piggy Bank credit cards and a money bag — the latter being the top regular symbol. On top of that, the slot uses two special icons: the top-hat pig Wild and the glamorous lady pig Scatter.

The full symbol paytable (values shown for a R1 total bet):

Every Wild that joins a winning line multiplies that combination by 3 in the base game, turning a modest 5-of-a-kind royal into a far more meaningful hit.

Wild substitution and Scatter multipliers

The Wild substitutes for every symbol except the Scatter and pays out the highest possible combination on its line. Any bet line win that contains at least one Wild is multiplied by 3 in the main game. During Free Spins, because the round's own multiplier stacks on top of the Wild multiplier, a line with a Wild can reach up to x18 — the Wild's x3 combined with the highest available Free Spin multiplier of x6.

Scatters work in parallel with the line system. Two or more Scatters anywhere on the reels pay out a multiplier of the total bet:

2 Scatters — x2 3 Scatters — x4 4 Scatters — x15 5 Scatters — x100

Because Scatters pay on the total stake (not per line), they are the main source of big direct hits outside of the Free Spins feature.

Free Spins with clickable Scatter menu

Landing 3, 4 or 5 Scatters anywhere on the reels triggers the bonus round, but before the Free Spins start the game does something unusual: the Scatters flip over and each reveals a different "number of spins + multiplier" combination. The player picks one. The full selection table used by the slot:

The chosen multiplier applies to every win inside the bonus, including Wild-assisted line hits. Additional Scatters landing during the round award +1 Free Spin each, so re-trigger potential is built straight into the feature. Free Spins are played at the same bet and line count as the triggering round, and the total win is added to the base-game result once the feature ends.

In a practical Piggy Riches demo run, 3 Scatters with the "9 Free Spins × x5" option is usually the most aggressive pick — fewer rounds, but every hit counts five times over. Higher Scatter counts (4 or 5) open the x6 multiplier tier, which has no direct equivalent in the base game.

Paylines, betting range and RTP

The 15 fixed lines run in varied horizontal, zig-zag and V-shaped patterns across the 5×3 grid, and the in-game help screen shows each of them explicitly. Because the number of lines is locked, bet adjustments change only the stake per spin.

The bet range stretches from R0.15 up to R300 per spin, which covers both low-stake sessions and high-roller play. The official theoretical RTP sits between 95.80% and 96.38%, depending on how the Scatter bonus options are picked — the game's help menu explicitly notes that the optimal strategy is to always pick the gift box with the highest multiplier, which is what delivers the 96.38% ceiling. Anything else lowers the long-term return.

Volatility is officially rated medium, and with a hit frequency around 34% roughly one in three spins produces a paid combination. The advertised max win is 2,400x the total bet, reachable mainly through stacked Wilds inside a high-multiplier Free Spins run. A Piggy Riches demo is a simple way to see how often the Scatter menu appears before committing real funds.

Payout Mechanics & Math Profile

Piggy Riches is built on a traditional 5×3 grid with 15 fixed left-to-right paylines, which is the foundation every mathematical behaviour of the game flows from. Unlike cluster or Scatter Pays formats, here reel order matters — symbols must line up starting strictly from reel 1, so the position weight on the first three reels is disproportionately important. Missing reel 1 means missing the line entirely, no matter what lands further right.

The mechanic that really steers the RTP is the Wild multiplier on reels 2, 3 and 4. Wilds sit on the middle three reels only, which concentrates their impact: a single Wild on any active line turns that line into a ×3 hit, and two Wilds on the same line stack multiplicatively into ×9. During the feature this scales further against the Free Spin multiplier, reaching ×18 at the top — so a large share of the variance lives inside Wild-assisted line wins during Free Spins, rather than inside the base game itself.

The Scatter layer operates on a separate math track. Because Scatter payouts (x2 / x4 / x15 / x100 of total bet) do not depend on lines, they act as a direct RTP injection that bypasses the payline geometry entirely. More importantly, the Scatter doubles as a selectable bonus trigger: the clickable menu actively ties RTP to player choice, and only the top-multiplier pick brings the return to 96.38%. This makes Piggy Riches one of the rare classic NetEnt titles where strategy has a measurable effect on long-term payout.
