The T-Rex II slot is RealTime Gaming's 2019 follow-up to its dinosaur classic: five reels, 25 lines, free spins and a progressive jackpot. Its RTP and volatility aren't published, so this review shows what is confirmed, what isn't, and what that means for your bankroll before you play for real money.
T-Rex II is a 5x3 RTG slot released September 23, 2019, with 25 lines listed by a third-party catalog.
No RTP or volatility figure is published in the sources we rely on, so ask the casino or check the in-game help.
The listed max win is 12,500x your total bet, which is $12,500 on a $1 spin.
Silver Oak's own mobile page names T-Rex II; for other casinos, check the lobby.
Bonus terms at some offshore casinos exclude progressive slots, so read them before playing T-Rex II with bonus funds.

T-Rex II slot at a glance
T-Rex II is a five-reel dinosaur slot from RealTime Gaming, the Atlanta-founded studio that now operates largely from Costa Rica and markets its US-facing catalog under the SpinLogic Gaming name. It arrived on September 23, 2019, a decade after the original T-Rex slot from 2009. It's one of many titles in our online slot reviews.
The game keeps the original's simple recipe: a wild, a scatter, a free spins round and a progressive jackpot. What it doesn't have, at least in any source we can point to, is a published return-to-player figure or a volatility rating. That gap shapes most of the advice on this page.

How the T-Rex II features work
The feature list for T-Rex II is short. Here is what each listed element does in general terms, without adding numbers the sources don't give.
Wild symbol
A wild stands in for regular symbols to complete line wins. Which symbols it can't replace, and whether it pays on its own, is set out in the in-game paytable.
Scatter symbol and free spins
A scatter pays wherever it lands rather than along a line. In T-Rex II the scatter is listed alongside a free spins round. The number of spins awarded and the exact trigger aren't in the sources we use, so check the game's help screen before you assume anything about the bonus.
Progressive jackpot
T-Rex II is listed with a progressive jackpot. RTG runs two broad kinds: random "Real Series" jackpots that a single casino or operator group sets up, and pooled progressives shared across casinos, such as Aztec's Millions. Which kind a casino attaches to T-Rex II isn't stated in our sources, and the jackpot amount you see is set by the casino's own meter.
The T-Rex II progressive jackpot explained
According to Realtime Gaming's Wikipedia entry (opens in a new tab), RTG's Real Series random jackpots are local to one casino or a group run by the same operator, and they can be won at random whatever symbols land. Pooled jackpots, by contrast, collect from many casinos into one prize.
For you as a player, this means the jackpot on T-Rex II can differ from one casino to the next. Two sites running the same slot may show different jackpot amounts and may have different rules about whether a bet size affects your chance. Our guide to RTG Real Series jackpots goes deeper.

T-Rex II RTP: why no figure is published
RTP is the share of all money staked that a slot is designed to pay back over millions of spins. For T-Rex II, no RTP appears on the third-party catalog page we rely on, and RealTime Gaming's own site wasn't reachable for checking. We won't guess.
The original T-Rex is listed at 97.5%, but a sequel's RTP can be set differently, and offshore casinos running RTG games may pick from more than one version. Our guide on how slot RTP works explains why the same title can carry different returns at different sites.
Open T-Rex II in demo or real mode at your casino and look for the "i", help or paytable button.
Search the help pages for "return to player", "RTP" or "theoretical payout".
If nothing is shown, ask live chat or email support for the configured RTP of T-Rex II at that casino.
Write down the answer and the date, since settings can change.
If the casino won't say, treat the game as an unknown and size your bets more cautiously.
What a $50 budget means on the T-Rex II slot
Expected loss is total amount staked multiplied by the house edge (100% minus RTP). Since T-Rex II has no published RTP, the table below uses two illustrative RTPs, 95% and 97%, to show the range. These are examples, not the game's figures.

The arithmetic for the $1 row: 100 spins x $1 = $100 staked. At 95% RTP the house edge is 5%, so $100 x 0.05 = $5 expected loss. Real sessions swing far above and below that average, which is what volatility describes. With no published volatility for T-Rex II, assume swings can be large and pick a stake that lets your $50 last.
The listed max win of 12,500x works out to $3,125 at $0.25, $12,500 at $1 and $62,500 at $5. That is a ceiling, not an expectation. Read our bankroll management guide for ways to set a stop-loss before you start.
Planet 7 Casino is reported by third-party reviewers to run RTG software, and Decode Casino advertises RTG slots on its own site. Neither publishes a full game list we could check, so look for T-Rex II in their lobbies before depositing. Lobbies change, and a title shown today can be removed.
Playing T-Rex II with a bonus
Welcome bonuses at RTG casinos are built for slots, but progressive slots are a common exclusion. Silver Oak's terms and conditions (opens in a new tab) list progressives among games excluded from bonus play. Because T-Rex II carries a progressive jackpot, check whether your casino classes it as a progressive before you wager bonus funds on it.
Playing an excluded game can void bonus winnings. Our pages on game weighting and wagering requirements explain how much play a bonus demands. Table games are often excluded or count for less, so don't assume a bonus can be cleared on blackjack.

Is it legal to play T-Rex II for real money in the USA?
Real-money online slots are licensed only in New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. The casinos that offer T-Rex II to US players are offshore and are not licensed or regulated by any US state, so there's no state regulator to complain to if a dispute arises. Your state's law decides what's allowed; our offshore casino legality guide explains the picture state by state.
Where to play T-Rex II with an offer via our links
The three casinos below run RTG games. They are offshore, not licensed by any US state, and Michigan's Gaming Control Board named Silver Oak and Planet 7 in cease-and-desist letters on April 9, 2025 (opens in a new tab).

Frequently asked questions
What is the RTP of the T-Rex II slot?
No RTP for T-Rex II is published in the sources we rely on. The third-party catalog that lists its specs gives no figure, and RealTime Gaming's own pages couldn't be checked. Some RTG titles run at different returns at different casinos, so the reliable step is to open the game's help screen or ask the casino's support team. Our explainer on what RTP means shows how to use the figure once you have it.
Does T-Rex II have a progressive jackpot?
Yes, T-Rex II is listed with a progressive jackpot feature. RTG supports both random Real Series jackpots, set up by one casino or operator group, and pooled progressives shared across casinos. Which type a casino connects to T-Rex II isn't stated in our sources, so the jackpot size can vary between sites. See what a progressive jackpot is for how the meters grow and how they pay.
What is the max win on T-Rex II?
The listed max win is 12,500x your total bet, from a third-party review figure. That equals $3,125 on a $0.25 spin, $12,500 on a $1 spin and $62,500 on a $5 spin. It's a ceiling rather than a realistic target. Bonus max cashout rules can also cap what you withdraw from bonus play, as explained in our max cashout rules guide.
Is T-Rex II a high volatility slot?
Its volatility isn't published in the sources we use, so we can't rate it. The original 2009 T-Rex is listed as high volatility, but sequels can be tuned differently. Until your casino or the game's help pages say otherwise, plan for big swings by choosing a stake that lets your budget cover plenty of spins. Our guide to slot volatility explains how swings affect a session.
How many paylines does T-Rex II have?
A third-party catalog lists 25 "betways" on a 5x3 grid, but it doesn't say whether these are fixed paylines or ways to win. The original T-Rex is listed the same way. Open the game's paytable at your casino to confirm how wins are counted before you set your stake. Our glossary entries on paylines and ways to win explain the difference.
Can I play T-Rex II with a welcome bonus?
Possibly, but check the terms first. Some RTG casinos exclude progressive slots from bonus play, and Silver Oak's terms list progressives among excluded games. Because T-Rex II carries a progressive jackpot, a casino may treat it as excluded, and playing excluded games can void bonus winnings. Our guide to how to clear a casino bonus covers what to read before you start.
Which casinos have the T-Rex II slot?
Silver Oak names T-Rex II on its own mobile casino page, which is the clearest confirmation we have. Other RTG casinos may also carry it, but we haven't seen it named on their sites, so check each lobby. All of these casinos are offshore and not licensed by any US state. Read our Silver Oak Casino review for its terms, banking and Michigan regulator action.
Can I play T-Rex II for free?
Many RTG casinos offer a demo or practice mode with play credits, but availability varies and it isn't confirmed for T-Rex II at any specific casino. Demo play is a sensible way to see the paytable and free spins round before staking real money. Demo results don't predict real-money results. Our demo mode guide explains how practice modes work and what they can't tell you.
Can I play T-Rex II on my phone?
Yes, T-Rex II is one of the few RTG slots with a confirmed mobile listing: Silver Oak's own mobile casino page names it among its featured games. That page is the casino's primary source, so it's a firmer sign than a third-party list, though lobbies can change. Elsewhere, search the mobile lobby before depositing. The 5x3 grid and 25 lines play the same on a phone, and the cost per spin doesn't change with screen size. Our Silver Oak mobile guide explains how its instant-play site works.
How is T-Rex II different from the original T-Rex slot?
T-Rex II is the 2019 sequel to RTG's 2009 T-Rex, and both use a 5x3 grid with 25 betways, free spins and a progressive jackpot. The main gap is in published data: the original is listed at a 97.5% RTP and high volatility, while T-Rex II has neither figure published. T-Rex II's listed max win is 12,500x, and no max win is published for the original. If a confirmed RTP matters to you, the first game is better documented. Read our original T-Rex slot review to compare.
How do I withdraw T-Rex II winnings from Silver Oak?
Silver Oak's banking page lists Bitcoin, bank wire, check and Coindraw for withdrawals, with Bitcoin from $50 to $2,500 per request at a fee of up to $40 and a 7 to 10 day time. Its terms add a review period of 7 to 10 business days before payment, a weekly limit from $2,500 that rises with VIP level, and an 8% fee if a deposit wasn't wagered at least once. Complete ID checks early to avoid extra delays. Our Silver Oak withdrawals page covers each method.
How much does an hour of T-Rex II cost?
Because T-Rex II has no published RTP, its hourly cost can only be shown as a range. Assuming 400 spins an hour at $1, you'd stake $400: at an illustrative 95% RTP that costs $20 on average, and at 97% it costs $12. At $0.25 a spin, the same hour costs $5 or $3, and at $5 a spin it's $100 or $60. Ask the casino for its configured figure before choosing a stake. Our gambling budget guide shows how to set a session limit.
Is it legal to play T-Rex II in Georgia?
No, Georgia doesn't license online casinos, so real-money slots like T-Rex II have no legal, state-regulated outlet there. The state has no casino or sports betting regulator at all; the Georgia Lottery Corporation oversees only the lottery, with a minimum age of 18. There's no statewide sweepstakes casino ban either. The offshore casinos that carry RTG games aren't licensed in Georgia, so players in Atlanta, Columbus and Augusta have no state body to complain to. Read our Georgia online casinos page for the details.
