Stinkin’ Rich Slot Review: The Complete IGT Stinkin’ Rich Family

Every game covered here is built by IGT, the studio that also operates as International Game Technology and distributes its online catalog through IGT PlayDigital to regulated US operators. Stinkin’ Rich is a video slot wrapped in a luxury-gone-sour cartoon theme, and the core loop rarely changes across versions: a 5-reel grid with 100 fixed paylines, a skunk that works as both a scatter and a wild, a pick-style Trash for Cash bonus and a Keys to Riches free-spins round that can be retriggered a long way. What shifts from build to build is the return-to-player figure and, on the 2024 release, the addition of a Random Wilds feature and stacked skunk wilds.

Name clarification, read this first. This page was requested to cover Stinkin’ Rich and a title listed as “Stinkin’ Rich Skunky Riches.” There is no separately documented IGT release under the exact name “Skunky Riches,” and BestSlotsUSA does not publish specifications it cannot verify. The genuine companion game, and the one covered in full below, is Stinkin’ Rich: Skunks Gone Wild, IGT’s 2024 online sequel. If a lobby or a listing points you to “Skunky Riches,” treat it as an informal nickname or a mislabel for one of the two verified titles here, not as a distinct machine with its own math. Every spec on this page belongs to either the original Stinkin’ Rich or to Skunks Gone Wild, and the two are never quoted interchangeably.

Quick-View Table: The Flagship Stinkin’ Rich

These headline numbers describe the original Stinkin’ Rich as IGT ships it online, with land-based context noted where it matters. Where the studio does not publish a figure, the cell says so rather than guessing a number. Because IGT sells the game in more than one return configuration, the RTP is given as a range and explained in full further down. To understand why that return figure matters before you deposit, our RTP explainer is a useful companion.

Version Comparison Table

This is the fastest way to see how the family splits. The original is both a casino-floor cabinet and an online remaster, while Skunks Gone Wild is an online-only 2024 sequel. The third row is the unverified “Skunky Riches” name, kept in the table only to show honestly that it carries no separate published specification. RTP and feature figures come from IGT and from operator pay tables where published; “Not published” means the studio has not released that number.

Game Overview and How Stinkin’ Rich Plays

Stinkin’ Rich pokes fun at the idea of having so much money you no longer know what to do with it. The reels are stacked with a wealthy old man, a fur-coated old lady, two spoiled brats and a blue-haired rich woman who tops the pay table, all surrounded by things that stink: garlic, a rotten egg, blue cheese, a fish and a pair of worn boots, with the skunk as the running gag. The grid is a 5-reel layout that shows five rows on the outer reels and three on the center reel, a 5-5-3-5-5 shape, and it runs on 100 fixed paylines that pay left to right on three or more matching symbols.

The base game is deliberately quiet, which is the single most important thing to understand before you size a bet. Ordinary line wins keep a session ticking, but the money that makes Stinkin’ Rich worth playing sits in its two bonus features rather than on the main reels. That gives the game a medium-to-high volatility profile: you can spin for a while on modest returns, then a triggered Keys to Riches round or a lucky Trash for Cash pick lifts the session all at once. If ways-to-win math or variance is new to you, the how to play primer covers payline betting, and the volatility guide explains why the swings feel steep on a feature-driven slot like this one.

What has kept Stinkin’ Rich on floors and in online lobbies for so long is its personality. The cartoon art, the smug rich family and the skunk that scurries across the reels give a fairly standard 100-line slot a sense of humor that plenty of flashier games lack. The loop is easy to learn and hard to tire of: spin the base game, bank small line wins, and chase either the Keys to Riches symbols that open the free spins or the Trash for Cash logo that fires the pick bonus. The 2024 Skunks Gone Wild sequel keeps that exact rhythm and layers a Random Wilds feature on top, which is covered version by version below.

Symbols and What They Pay

The symbol hierarchy is consistent in spirit across both versions, which is why a player who learns one can sit down at the other without relearning the pay table. From the top of the paytable down, the reels carry the following.

• The blue-haired rich woman (top symbol): the premium picture pay and the biggest regular win in the game, reported at up to 10,000x the line bet for five on a line.
• The wealthy family: the old man, the fur-coated old lady and the two spoiled brats sit just below the top symbol as the mid-tier picture pays that build the bulk of ordinary wins.
• The stinky items: garlic, the rotten egg, the fish, the blue cheese and the smelly boots fill out the lower end as the filler symbols that pay small amounts for three, four or five across the lines.
• The skunk wild: the skunk substitutes for every symbol except the scatter and the two bonus symbols. In the original it lands on reels 2, 3 and 4; in Skunks Gone Wild it can arrive stacked and can be sprayed across the reels by the Random Wilds feature.
• The skunk scatter: a skunk styled as the scatter that pays from anywhere on the screen, returning 3x, 20x or 100x the total bet for three, four or five.
• Keys to Riches symbol: the bonus symbol that opens the free spins when it lands correctly on the left reels.
• Trash for Cash symbol: the second bonus symbol, a logo that fires the pick bonus when it lands on reels 3, 4 and 5.

Because the game scales its pay values with the bet, exact per-symbol credit pays are best read from the in-game pay table at your chosen stake. The order of the hierarchy, however, is stable between the original and Skunks Gone Wild, so the rich woman remains the symbol you most want to see fill a line in either title.

Bonus Symbol Cross-Check

Here is the consistency check that matters, because Stinkin’ Rich carries more special symbols than most slots and it is easy to mix them up. Both verified versions use the same set of trigger symbols in the same roles. The skunk is the scatter that pays scattered wins, the Keys to Riches symbol is the free-spins trigger that must land on the left reels, and the Trash for Cash symbol is the pick-bonus trigger that must land on the right reels. That much is shared, so a player who learns the original will recognize every bonus symbol in the sequel.

Where the two versions genuinely differ is the wild, not the bonus triggers. In the original Stinkin’ Rich the skunk wild simply appears on reels 2, 3 and 4 and substitutes. In Stinkin’ Rich: Skunks Gone Wild the same skunk wild is upgraded: it can land stacked to fill a reel, and a Random Wilds feature can spray up to 15 wilds across reels 2, 3 and 4 on a single spin. So the scatter and the two bonus symbols are shared and behave the same way, while the wild is the one symbol whose behavior you should not assume carries over unchanged from the original to the sequel.

How to Trigger the Bonus

Stinkin’ Rich has two separate bonus triggers, and they work in opposite corners of the reels, which is the one rule worth memorizing.

The Keys to Riches free spins are triggered from the left. Land three Keys to Riches symbols on reels 1, 2 and 3 along an active payline and you open the free-spins round. Because the trigger is tied to paylines rather than to scattered positions, the number of lines on which the keys line up feeds directly into how many free spins you receive: each triggering payline adds spins, so lining the keys up across several paylines at once awards a far larger round than a single-line trigger. During the round, more Keys to Riches symbols retrigger and stack additional spins on top.

The Trash for Cash bonus is triggered from the right. Land the Trash for Cash logo simultaneously on reels 3, 4 and 5 and the game switches to a pick screen. This trigger is independent of the free spins, so a session can produce either feature on its own or, over time, both. Neither bonus can be bought; there is no feature-buy option on any Stinkin’ Rich build, so both rounds have to be reached by landing the symbols naturally, which rewards patient bankroll play on a game with quiet base reels. If you want to understand why a feature-driven slot swings the way this one does, the how to choose guide pairs well with this section.

How the Bonus Works

Once triggered, each feature plays very differently, so it is worth walking through what actually happens on the screen.

The Keys to Riches free spins begin with a base award, commonly five free spins for a single-line trigger, and grow from there because each additional triggering payline multiplies the award. Lined up across enough paylines, and then retriggered by more keys landing during the round, the spin count can climb a long way; the original is widely reported to reach as high as 325 total free spins on a fully built-out round, while the 2024 sequel raises that ceiling substantially. Inside the round the reels play like the base game, so the value comes from a high spin count meeting the premium symbols and, in the sequel, the extra wilds. There is no wheel and no multiplier ladder on the free spins themselves; the drama is in how far the retriggers extend the round.

The Trash for Cash pick bonus is a short, self-contained round. After the Trash for Cash logo lands on reels 3, 4 and 5, you are shown a row of trash cans and asked to pick. Lifting a lid reveals a cash value or a multiplier, with picks generally worth 2x to 5x that combine into a total prize, and the feature is built to pay out in a band around 6x to 40x the total bet before it ends. It is a pick-and-reveal round rather than a spinning feature, so it resolves quickly and does not retrigger, which makes it the more predictable of the two bonuses. Skunks Gone Wild keeps the same Trash for Cash structure, so the pick bonus feels familiar even though the sequel adds its Random Wilds mechanic to the base game around it.

Version by Version

Stinkin’ Rich (land-based original, online remaster 2016)

The original Stinkin’ Rich began life as an IGT casino-floor cabinet in the early 2000s, where its wealthy-family cast and skunk gag made it a recognizable machine long before it ever reached a browser. IGT later remastered it as an online HTML5 game, with the widely cited online release landing in 2016. It runs the family-defining setup: a 5-reel, 5-5-3-5-5 grid with 100 fixed paylines, the skunk that doubles as scatter and wild, the Keys to Riches free spins triggered from the left reels, and the Trash for Cash pick bonus triggered from the right. The scatter pays 3x, 20x or 100x the total bet for three, four or five, and the top rich-woman symbol is reported to pay up to 10,000x the line bet.

The number a US player should check first is the return, because IGT ships Stinkin’ Rich in more than one RTP configuration and lets the operator choose which to load. Published figures cluster around 92.5 percent at the low end, roughly 94.3 percent in the middle and up to about 96.24 percent at the top, so two lobbies can offer a game that looks identical yet pays meaningfully differently. The volatility is medium to high, with the base game intentionally thin and the real returns concentrated in the two features. IGT does not publish a single certified maximum-win multiplier for the game, so this page reports the top symbol pay and the frequently cited coin ceiling rather than inventing one overall figure. This is the version most legal US players will recognize, and it is the reference point every spec on the page is measured against.

Stinkin’ Rich: Skunks Gone Wild (2024)

Stinkin’ Rich: Skunks Gone Wild is IGT’s modern sequel, released online in January 2024, and it is the version to seek out if you want a fresher build of the theme. It keeps the 5-reel, 100-payline frame and the same cast of rich characters and stinky props, and it carries over both signature bonuses: the Keys to Riches free spins and the Trash for Cash pick round. Its published RTP is 95.14 percent, and it plays as a high-volatility slot, so the base game is quiet and the swings are larger than a medium-variance title would give you. IGT has not published a single maximum-win multiplier for the sequel, so that figure is marked “Not published” rather than estimated.

What makes Skunks Gone Wild worth a separate entry is the wild. The skunk wild can now land stacked to fill a reel, and the headline addition is a Random Wilds feature that can spray up to 15 wilds across reels 2, 3 and 4 on a single spin, manufacturing full-reel wins that the original could not produce. The free-spins ceiling is also raised well beyond the original’s, with retriggers able to build the round far higher. In short, the sequel keeps everything a Stinkin’ Rich player already knows and bolts a much more generous wild engine onto it, which is the main reason to pick it over the classic when both are available.

Stinkin’ Rich Skunky Riches (unverified name)

This entry is an honest correction rather than a set of invented specifications. There is no separately documented, widely released IGT game marketed under the exact name “Stinkin’ Rich Skunky Riches.” The name most likely refers informally to one of the two verified titles on this page, and because BestSlotsUSA does not publish specifications it cannot confirm, every spec cell for this title is marked “Not published.” If you have seen a machine or a lobby tile calling itself “Skunky Riches,” the safe assumption is that it is either the original Stinkin’ Rich or the 2024 Skunks Gone Wild build under a casual label, and you should confirm the actual title and its posted RTP in the game’s information screen before you deposit. Treat any specification quoted for “Skunky Riches” as unverified until you can match it to one of the two real games above.

RTP and Max Win in Context

Return figures are where the honesty of a lobby shows on this game, because Stinkin’ Rich is sold in several RTP builds. The original’s published configurations run from roughly 92.5 percent at the bottom to about 96.24 percent at the top, a spread of nearly four percentage points on what is nominally the same machine, while Skunks Gone Wild is published at a single 95.14 percent. No other number matters more before you deposit, and the reels look identical whether you are getting the best build or the worst, so the only way to be certain is to open the game information panel and read the posted RTP. Our random number generator explainer covers how certified software keeps those posted figures honest at licensed operators.

On the top end, IGT does not attach a single certified maximum-win multiplier to Stinkin’ Rich the way some studios cap a game at a clean figure. What is documented is that the premium rich-woman symbol pays up to 10,000x the line bet for a five-of-a-kind, and that the biggest sessions come from a deeply retriggered Keys to Riches round meeting those premium symbols. Some listings translate the ceiling into a coin figure in the region of 500,000 coins, but because the studio does not publish one authoritative number, this page reports the symbol pay and treats larger single-figure claims with caution rather than presenting them as certified.

Stinkin’ Rich on Mobile

Both verified versions are built to run in a mobile browser and inside the operator apps, with no separate download. The 100-payline grid scales to a portrait phone screen, the Keys to Riches free spins and the Trash for Cash pick bonus play identically to desktop, and the skunk animations and cartoon art carry over intact. The pick bonus in particular translates cleanly to touch, since lifting a trash-can lid is a single tap, and the Random Wilds feature in Skunks Gone Wild is just as readable on a small screen as on a monitor. Because Stinkin’ Rich leans on its features rather than the base reels, a stable connection matters more than raw speed, so playing on wifi is worth it if you can. Our mobile slots hub covers device compatibility and the operator apps that carry IGT games.

Where to Play Stinkin’ Rich

Stinkin’ Rich and Skunks Gone Wild are IGT titles, which means they live inside the licensed operator apps in the regulated United States rather than on any unlicensed site. To find the current list of vetted, state-licensed operators that carry IGT’s catalog, along with the states each one serves and the sign-up offers attached, start at the legal casino sites directory and filter to your state. Because IGT rotates its online lineup and each operator loads its own RTP build, the in-lobby information screen is always the final word on whether a specific Stinkin’ Rich title is live and what return it is set to. The original also survives as a physical cabinet on many casino floors, so if you cannot find it online in your state, the land-based machine remains a fallback.

Betting, Lines and Bankroll

Both versions run on 100 fixed paylines, which is an important detail for bankroll planning: you are always paying to keep all 100 lines active, so the total spin cost is the line bet multiplied across the full board rather than something you dial down by switching lines off. On common online builds the original starts from about 1.00 per spin, with some configurations allowing as little as 0.01 per line, and climbs to roughly 200.00 per spin at the top, while Skunks Gone Wild follows a similar structure with its own operator-set range. The exact minimum and maximum you see will depend on the lobby, so check the bet selector before your first spin.

Because the base game is quiet and the money lives in the features, a sensible approach is to size your stake so your balance can absorb a stretch of feature-free spins while you wait for either three Keys to Riches symbols on the left or the Trash for Cash logo on the right. Raising your bet to chase a bonus does not make either trigger more likely, since every spin is independent, so the steadier play is to pick a stake you can repeat many times over rather than a large one you can only afford a few of. The features arrive on their own schedule, and the point of a medium-to-high volatility game is that you cannot force them.
