RealTime Gaming (RTG) casinos

What are RealTime Gaming (RTG) casinos?

An RTG casino is any online casino whose lobby is built on RealTime Gaming's platform and game library. The casino handles the cashier, bonuses and support, while RTG supplies the slots, table games, video poker and the jackpot networks that link them.

For American players this matters because RTG is one of the few studios whose games are widely offered by offshore casinos that accept US sign-ups. You won't find RTG titles at the state-licensed online casinos in New Jersey, Pennsylvania or Michigan; you'll find them at sites licensed overseas, if at all. Our casino software providers hub compares RTG with the other studios these sites use.

Since 2022 many RTG games appear under the SpinLogic Gaming name, which third-party reviewers describe as RTG under a different brand. The games and the math behind them are the same, so a casino advertising SpinLogic is effectively an RTG casino. If you want the short version first, our explainer on what RTG is covers it in a few paragraphs.

RTG history: from Atlanta to Costa Rica

Wikipedia, PokerListings, GamesHub and LCB all date RealTime Gaming to 1998 in Atlanta, Georgia. Only one source, GamblingNews, names a founder (Daniel Schultz); the others don't, so treat that detail as unconfirmed.

The big turn came after Congress passed the Unlawful Internet Gambling Enforcement Act in 2006. PokerListings says the law pushed RTG to move its operations out of the US, and development shifted to Costa Rica in 2007 and 2008. The Wikipedia entry on RealTime Gaming (opens in a new tab) records the sale to Hastings International in January 2007, while GamesHub gives 2008.

Today the studio's base is reported as Heredia, Costa Rica. GamblingNews also lists an address in Wan Chai, Hong Kong, which conflicts with the other sources, and no official RTG page could confirm either.

Who owns RealTime Gaming, and what license does it hold?

Wikipedia names the owner as Hastings International, a Curaçao company managed by HBM Group. No other source in our checks contradicts the owner, only the year of purchase.

Licensing is less clear. SlotCatalog lists a Curaçao license. PokerListings lists Curaçao and Panama in one place and Costa Rica and Curaçao in another, and GamesHub mentions GLI, the Curaçao Gaming Control Board and the Kahnawake Gaming Commission. No license number is published in any of these sources, and RTG's own site couldn't be reached to settle it.

A software supplier's license doesn't license the casino. Each RTG casino has its own operator and its own license claim (or none), and no US state regulator covers any of them. See our offshore casino legality guide for what that means in practice.

Popular RTG slots and their published specs

Slots make up the bulk of the RTG library: SlotCatalog counts 318 video slots out of 347 games, PokerListings says 300+, and LCB says it has reviewed 376 RTG slots. The table below lists well-known titles with figures reported by third-party catalogs; RTG's own pages weren't available to confirm them.

Two patterns stand out. Older RTG titles such as Coyote Cash and Goldbeard are reported at 97.5%, while many newer ones sit at 95% to 96.25%. And a fair number of RTG slots carry a progressive jackpot on top of the base game, which is part of why the studio is popular with US-facing casinos.

Recent releases include Mega Monster (2024) and Horseman's Prize (2025). For full feature breakdowns, see our RTG slot reviews, and for what those percentages mean, read how slot RTP works.

RTG table games and video poker: the cost in dollars

RTG also builds blackjack variants, roulette, poker-based table games, video poker and specialty games such as keno and Fish Catch. The RTPs below come from third-party sources. The last column shows the expected loss on $1,000 of total bets, calculated as total stake × (100% − RTP).

Here's a worked example. Playing Super 21 at $10 a hand for 100 hands puts $1,000 in action, so the expected cost is about $4. The same $1,000 run through Sevens Wild costs about $68.50 on average. Short sessions swing far more than these averages, in both directions, but the house edge is what you pay over time.

RTG progressive jackpots and Real Series random jackpots

RTG runs two kinds of jackpot. The first is the Real Series: Wikipedia explains that non-progressive Real Series slots can carry tiered random jackpots that are local to one casino or to a group run by the same operator, and that can drop regardless of the symbols on the reels. Our Real Series jackpots guide walks through how these work.

The second is pooled progressives. Wikipedia names Jackpot Piñatas and Aztec's Millions as jackpots shared across casinos, and PokerListings adds Megasaur. GamesHub reports that RTG's networked jackpots often pass $1 million and cites an Aztec's Millions win of more than $1.7 million at one RTG casino. It also describes a Jackpot Pyramid pool and a Boiling Point Jackpot with up to five tiered meters.

A large jackpot doesn't make a game better value. Part of every stake feeds the meter, and the odds of hitting the top prize aren't published. Our page on the RTG progressive jackpot system sets out what is and isn't known.

Are RTG casino games fair? Testing and RNGs

LCB and GamblingNews both report that RTG games are tested by Technical Systems Testing (TST), an independent lab. GamesHub separately mentions GLI. Neither report includes a certificate date or a link to a certificate, so the scope and recency of that testing aren't published.

Every RTG game uses a random number generator to decide each result, and nothing about past spins changes the next one. Our guide to how RNGs work explains this, and our answer on whether RTG games are fair covers the evidence in more detail.

The weak point isn't usually the game; it's the casino. An RTG lobby can be identical at two sites while their withdrawal caps, bonus rules and complaint records differ widely. No US regulator audits the casino's settings or handles disputes, which is the main gap compared with a state-licensed site.

Which real money casinos run RTG software?

Six of the seven partners in our ranking are reported to run RTG or SpinLogic games, though the evidence varies. The exception is Miami Club, ranked second, which runs WGS (Wager Gaming) games rather than RTG. The table shows who reports it and what kind of source it is.

You'll also see RTG at non-partner sites such as Raging Bull Slots, whose own terms name RTG, and Jackpot Capital, which shows an RTG footer logo. Our ranked list of the best RTG casinos compares the partners on bonuses, banking and caps. The ranking is commercial: we earn commission from partners.

How to check an RTG casino before you deposit

Because the games are the same everywhere, the checks that matter are about the operator. Work through these before sending money.

1. Read your state's law on online gambling. Our state-by-state guide links each state's page.
2. Find the operator and license claim in the casino's terms, and compare it with what reviewers report.
3. Search the Michigan Gaming Control Board and other regulator releases for the casino's name.
4. Read the bonus terms in full: wagering, max cashout, max bet and which games count.
5. Check the banking page for weekly withdrawal caps, fees and minimum withdrawals.
6. Set a deposit limit and a session budget you can afford to lose before your first spin.

Are RTG casinos legal in the USA?

RTG casinos that accept American players are offshore, and no US state licenses or regulates them. Seven states license real-money online casinos (New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island), and RTG sites aren't among the licensed operators there.

Federal law doesn't make placing a bet a crime for the player; UIGEA targets payment processing for unlawful internet gambling. Whether playing is lawful depends on your state, and some regulators, such as Michigan's, call offshore operators illegal. The Michigan Gaming Control Board, for example, has sent cease-and-desist letters to RTG-powered sites; see our page on cease-and-desist letters.

In practice, playing offshore means no state regulator to complain to, no state-backed protection of your balance, and terms the casino sets and can change. Our offshore vs state-licensed guide compares the protections side by side.

RTG casinos with an offer via our links

The three offers below are from partners reported to run RTG games. All three are offshore, none is licensed by any US state, and you should check your state's law before signing up. Offers are for new players aged 21+ (18+ where allowed), and terms apply.

• Slot Madness Casino: $2,500 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Third-party reviewer LCB lists a 275% match up to $2,750 with code MAD275, a $30 minimum deposit, 30x (bonus + deposit) wagering on slots and no max cashout; the terms shown at sign-up apply. The Michigan Gaming Control Board named Slot Madness in an August 14, 2025 cease-and-desist release (opens in a new tab).
• SlotoCash Casino: $6,000 Welcome Bonus + 60 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). The casino's own terms advertise a different package, $7,777 + 300 spins over five deposits, with 25x (deposit + bonus) wagering, a $20 minimum per bonus, a $10 max bet and no max cashout. The board named SlotoCash in an October 8, 2026 release (opens in a new tab).
• Decode Casino: $5,000 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Decode's site shows a $111 free chip and crypto bonuses without visible terms; LCB lists code DECODE111 (111% up to $1,111, 25x bonus + deposit, $25 minimum). VegasSlotsOnline reports that Decode refuses players from Maryland, New Jersey, New York and Washington.

Worked example: a $100 deposit with a 275% match adds $275, and 30x on $375 means $11,250 of wagering. At a 96% RTP the expected loss on that wagering is about $450, more than the bonus itself, so treat any bonus as extra play time rather than profit. Free spins and bonus funds are slot-focused; table games are often excluded or weighted lower. See how wagering requirements work and, if gambling stops being fun, call 1-800-MY-RESET (1-800-697-3738) or visit NCPG (opens in a new tab).

21+ (18+ where allowed). Every casino game has a built-in house edge, so over time you should expect to lose what you stake. Set a budget before you play and stop when it’s gone: responsible gambling tools and free help. Gambling problem? Call or text 1-800-MY-RESET (1-800-697-3738).
