The Goblins Gluttony of Gems slot is a RealTime Gaming release from December 7, 2022 that combines a Hold and Win feature with a choice of free spins modes on a 5x3 grid with 50 betways. A third-party listing puts its RTP at 96.25%. Volatility and max win aren't published, so here's how to size your stakes.
How Hold and Win works in Goblins Gluttony of Gems
Hold and spin features, which RTG calls Hold and Win here, follow a familiar pattern: special symbols lock in place, the remaining positions respin, and new special symbols reset or extend the respin count. The listing records Hold and Win and respins, but not the trigger, the number of respins or what the locked symbols pay.
In most games of this type, the locked symbols carry credit values that add up at the end. Whether that's true here, and whether any fixed prizes sit on top, needs checking in the paytable.
Choosing a free spins mode
The listing records a free spins mode choice. Games with this mechanic usually let you trade more spins for smaller boosts, or fewer spins for bigger ones. Since the options aren't described, read them in the game before you commit.
Picking a mode isn't a way to raise the RTP. Mode choices are generally designed around similar long-run returns with different swings, though this game's options aren't described. If you're playing on a tight budget, the option with more spins tends to give a steadier round.
Sticky wilds:wild symbols that stay put for later spins in the round.
Expanding symbols: symbols that grow to cover more of a reel.
Multiplier: a factor applied to some wins; its size isn't published.
Extra free spins: a way to add spins to a running round.
Nudge: a reel shifts by one position, which can complete a win or set up a feature.
Goblins Gluttony of Gems RTP: what $50 buys
At 96.25%, the game keeps 3.75 cents of every dollar staked over the long run. One pass through $50 at any stake averages $1.88. The difference between stakes is how many spins, and how many shots at Hold and Win, you get.

The 400-spin column shows what happens when you keep replaying wins: the total staked grows and so does the average cost. With volatility unpublished, plan for swings either way and choose a stake that gives at least 100 spins. Our house edge explainer walks through the same formula for table games.
Royal Ace bonus on Goblins Gluttony of Gems: worked example
A third-party Royal Ace listing (opens in a new tab) reports a 200% match with 30x (bonus plus deposit) wagering on slots and a max cashout of 10x the deposit. Another reviewer reports 250% up to $2,500 with 35 spins, so the package is disputed; the offer via our link is shown below.
Deposit $50 and receive a $100 bonus, for $150 in play.
Wagering: 30 x $150 = $4,500.
Expected cost at the listed 3.75% edge: $4,500 x 3.75% = $168.75.
Max cashout at 10x the deposit: $500, so any balance above that would be removed.
On average you'd use up the bonus and some of your deposit before finishing.
That's the usual story with large matches: the max cashout rule caps the upside while wagering carries the cost.
Cashing out Goblins Gluttony of Gems wins at each partner
With no published max win, a big Hold and Win round could land well above a casino's weekly cap. These are the withdrawal rules reported for the three partners on this page.
Worked example: a $10,000 win would take two weeks at SlotoCash, but at least two months at Royal Ace or Slot Madness because of the $5,000 monthly cap. A bonus can cap things further; at Royal Ace, the reported 10x-deposit max cashout would limit a $50-deposit bonus to $500.
If Hold and Win is the draw, Coyote Cash 2 is a 2026 RTG release that also lists it; if gems are, Gem Strike shares the 2022 release year.
Is Goblins Gluttony of Gems legal to play in the USA?
Only seven states license real-money online casinos, and RTG games mostly appear at offshore casinos that no US state licenses. Whether you can play legally depends on your state's law, and the answer differs widely. Start with whether it's illegal to play at offshore casinos, then read your state on the states hub. Winnings are taxable federal income, as our gambling taxes guide explains.

Frequently asked questions
What is the RTP of Goblins Gluttony of Gems?
A third-party catalog lists Goblins Gluttony of Gems at 96.25%, a 3.75% house edge. That's a long-run average; one session can land far above or below it. Some casinos offer more than one RTP version of a game, so check the help screen. For how the figure is calculated and what it does and doesn't tell you, see our guide to how slot RTP works.
How do you trigger Hold and Win in Goblins Gluttony of Gems?
The trigger isn't described in any source checked, so read the game's paytable. In most Hold and Win games, landing a set number of special symbols starts a respin round where those symbols lock and new ones reset the count. No reliable source publishes how often it triggers here. Our hold and spin glossary entry explains the general mechanic and its usual variations.
Which free spins mode should I choose?
Pick based on your budget rather than hoping one pays more. The modes aren't described in our sources, but mode choices usually trade more spins with smaller boosts against fewer spins with bigger ones, at roughly the same long-run return. More spins tends to mean a steadier round. Our slot volatility guide explains why swing size matters for small budgets.
What is the max win on Goblins Gluttony of Gems?
No max win is published for this title. The third-party listing leaves the field blank rather than showing the 50,000x figure that appears on many other RTG entries. Check the game's paytable for any stated cap. If top-prize size matters to you, our answer on what slot pays the most explains how caps are set and why they rarely reflect typical outcomes.
Is Goblins Gluttony of Gems high volatility?
Its volatility isn't published, so it can't be rated with confidence. Hold and Win and sticky-wild free spins can pack a lot of the return into features, which often makes sessions streaky, but that's an inference rather than a rating. Size stakes for at least 100 spins. Our guide on bankroll management shows how to set stake and loss limits for unrated games.
Can I use a bonus on Goblins Gluttony of Gems?
Usually, since it's a regular slot, but check the casino's eligible-games list and max-bet rule. It doesn't carry a progressive jackpot in its listing, so progressive exclusions shouldn't apply. With a 3.75% edge, wagering $4,500 averages $168.75 in cost, so weigh the playthrough against the bonus. Our slots bonus guide shows how to compare offers.
Is there a free demo of Goblins Gluttony of Gems?
None of our sources confirms one. Some RTG casinos offer practice play, and others need an account first. Demo spins show how Hold and Win and the mode choice look, but results don't predict real-money sessions because every spin is random. Our page on free slots vs real money covers the differences and what to watch for.
Which casinos carry Goblins Gluttony of Gems?
No source checked confirms a casino carrying it, so search the lobby before depositing. RTG-powered offshore casinos are where to look; our list of the best RTG casinos covers partners reported to run the software. All are offshore and unlicensed by US states, so check your state's law and each casino's withdrawal limits first.
Is Goblins Gluttony of Gems legal to play in Colorado?
No, Colorado's Division of Gaming said in September 2025 that the only online gaming in Colorado is sports betting, so online slots like Goblins Gluttony of Gems have no state license there. Legal casino slots in Colorado are found in person, in the old mining towns of Central City, Black Hawk and Cripple Creek. The RTG casinos that carry this kind of game are offshore and unlicensed in the state. Read our Colorado slots page and the Colorado gambling overview.
Can I play Goblins Gluttony of Gems on my phone?
Likely yes, at a casino that carries it, because RTG casinos run as instant play in a mobile browser. Third-party reviews describe Royal Ace with instant play, mobile and download versions. No source confirms Goblins Gluttony of Gems in a partner lobby, so search the mobile site before you deposit. Hold and Win respins and the free spins choice work the same on a phone. Our answer to what is instant play and the best Android casinos list explain more.
How much does it cost to clear a SlotoCash bonus on Goblins Gluttony of Gems?
Using SlotoCash's 200% first-deposit match on its own site, a $100 deposit adds $200, and its 25x (deposit plus bonus) wagering means $7,500 in spins. At the listed 96.25% RTP, the average cost is $7,500 × 3.75% = $281.25, almost the whole $300 balance. Bets are capped at $10 while the bonus is active, and there's no max cashout. The offer via our link differs, so check the terms at sign-up. Our SlotoCash welcome bonus page has the details.
How do sticky wilds work in Goblins Gluttony of Gems?
Sticky wilds are wild symbols that stay in place for later spins of a round instead of disappearing, so each one can help complete wins more than once. The listing records sticky wilds alongside the free spins mode choice, but it doesn't say which mode uses them, how many can land or how long they stay. Check the paytable for those rules. Sticky wilds are part of the 96.25% RTP, not an extra. Our glossary entries on free spins and multipliers cover related features.
What does the nudge feature do in Goblins Gluttony of Gems?
A nudge shifts a reel up or down by one position, which can complete a win or move a special symbol into place for a feature. Goblins Gluttony of Gems lists a nudge among its many features, but the sources don't say when it happens or which symbols it applies to, so read the paytable before you play. Like every feature, the nudge is already counted in the listed RTP. Our paytable glossary entry explains how to read a game's rules screen.
Is Goblins Gluttony of Gems worth playing for its 96.25% RTP?
Its listed 96.25% RTP is above many RTG titles, costing $3.75 per $100 staked on average, and other RTG slots share that figure. Fortune Frog pairs it with low volatility and simple cascades, while Persian Treasures is rated high volatility. Goblins Gluttony of Gems has no published volatility rating but packs in Hold and Win, a mode choice and sticky wilds. Choose by the features you enjoy, since the average cost is the same. Our best high RTP casinos list compares partners.
Is Goblins Gluttony of Gems the same as Doragon's Gems?
No, they're separate 2022 RTG gem slots. Goblins Gluttony of Gems (December 2022) uses 50 betways with Hold and Win, a free spins mode choice, sticky wilds and a listed 96.25% RTP. Doragon's Gems uses 25 betways with cascading reels and a buy feature, is rated high volatility and lists a 25,000x max win, with no RTP published. If you want a published return, Goblins Gluttony of Gems is the one with a figure.
