The T-Rex Wild Attack slot is a RealTime Gaming dinosaur game released on January 18, 2024, using cascading reels on a larger 6x4 grid with 30 betways, plus respins and free spins with a multiplier. It's the fourth T-Rex title in RTG's catalog. No RTP, volatility rating or max win has been published, so here's how the cascades work and how to plan a $50 session without those figures.
RTG release dated January 18, 2024, per SlotCatalog (third-party).

T-Rex Wild Attack slot: RTG's fourth T-Rex game
RTG has returned to the tyrannosaur several times. The original T-Rex dates from 2009, T-Rex II followed in 2019, and T-Rex Lava Blitz arrived in 2026. Wild Attack, from January 2024, is the one that drops the classic 5x3 layout for a 6x4 grid with cascading reels.
With cascading reels, winning symbols are removed after a win and the symbols above drop down to fill the gaps, with new ones falling in from the top. If the new arrangement forms another win, the process repeats. One paid spin can therefore produce a chain of wins, and the chain ends when no new win forms.
On a 6x4 grid there are more positions for symbols to fall into, which gives chains more room to continue. Whether wins in a chain grow with a multiplier in the base game isn't stated; SlotCatalog only lists a multiplier for the free spins round.
Respins
Respins are listed as a separate feature. In RTG games they usually give one or more extra spins with some symbols held, triggered by a specific symbol or event. What triggers them here and what's held isn't published.
Free spins and the multiplier in T-Rex Wild Attack
A scatter is listed, and it usually starts the free spins round in RTG games. During free spins, a multiplier applies to wins. Combined with cascades, that can matter a lot: if the multiplier applies to every win in a chain, one spin can pay several multiplied wins in a row. The multiplier's size, whether it grows across cascades and the number of free spins aren't published.
That combination tends to concentrate the game's return in a small number of strong free spins rounds. It doesn't make the game pay more in total, since the RTP already includes those rounds. It does mean results between sessions can vary a lot.
Playing T-Rex Wild Attack for real money: three ways to spend $50
Without a published RTP, the cost of play is unknown, so the practical question is how you spread $50. Cascades don't cost extra: you pay once per spin, and every chained win from that spin is included. The table compares one long session with smaller ones.

Each row puts the same $50 through the game once, so the expected cost per point of edge is identical. What changes is the experience: 200 small spins give the free spins far more chances to appear than 10 large ones. If wins come back and you keep playing, your total wagered rises and so does the expected cost.
Check the info screen for the RTP and how the free spins multiplier behaves.
Decide how you'll split your budget before you start, as in the table.
Track total wagered, not just your balance; that's what the house edge applies to.
Stop at the limit. Cascades and near-misses don't change the odds of the next spin.
The missing figure: T-Rex Wild Attack RTP
No RTP is recorded for T-Rex Wild Attack in SlotCatalog or any other source we found, and we won't estimate one. The original T-Rex has a listed 97.5% RTP, but that's a different game from 2009 and tells you nothing reliable about this one. Our how slot RTP works guide explains where the figure usually appears in RTG games.
T-Rex is the only one with an RTP on record, at 97.5% according to SlotCatalog, a third-party figure. Its progressive jackpot can matter for bonuses, since some casinos exclude progressive slots. If you like cascades on a larger grid, Seahorse Surge also runs on 6x4 reels; PokerListings gives it two RTPs, 96% on the summary card and 96.1% in the text.
Is T-Rex Wild Attack legal for US players?
State law decides. New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island license real-money online casinos, and RTG games aren't reported among their providers. T-Rex Wild Attack is offered at offshore casinos that no state licenses. See our states with legal online casinos page for the full list.
In Michigan, the Gaming Control Board named Planet 7 in an April 9, 2025 release (opens in a new tab) and Slot Madness in an August 14, 2025 order (opens in a new tab), calling them illegal offshore operators. Royal Ace isn't named in any of the three releases covering our partners. Wherever you are, offshore play means no state regulator for complaints and no state-backed protection of balances.

Frequently asked questions
What is the RTP of T-Rex Wild Attack?
T-Rex Wild Attack's RTP isn't published in SlotCatalog or any other source we found. Check the info screen in the game at your casino. Don't borrow the original T-Rex's 97.5% figure, since it's a different game. Until you find the real number, you know your turnover but not your expected loss. Our RTP glossary entry explains the term.
How do cascading reels work in T-Rex Wild Attack?
After a win, the winning symbols disappear and the symbols above fall into their place, with new ones dropping in from the top. If that forms another win, it pays and the process repeats. All the chained wins come from the one spin you paid for. Our cascading reels glossary entry explains the mechanic in more detail.
Does T-Rex Wild Attack have a progressive jackpot?
No jackpot is listed for T-Rex Wild Attack in SlotCatalog's data. That's a change from the original T-Rex and T-Rex II, which both have progressives. Without a progressive, the exclusions some casinos apply to jackpot slots during bonus play shouldn't affect it, but confirm in the terms. Read our T-Rex II review for the progressive version.
How big is the T-Rex Wild Attack grid?
The game uses 6 reels and 4 rows, giving 24 symbol positions, with 30 betways according to SlotCatalog. That's larger than the 5x3 grid on the original T-Rex and T-Rex II. A bigger grid gives cascades more room to chain, but it doesn't change the house edge. Our ways to win glossary entry explains how layouts affect payouts.
What's the max win on T-Rex Wild Attack?
No max win figure is published for T-Rex Wild Attack. SlotCatalog leaves the field empty, and we haven't seen a figure elsewhere. The game's paytable may show a cap as a multiple of your bet. A max win is a rare event, so plan your budget around what you can afford to lose instead. Our jackpot odds guide explains why.
Which casinos offer T-Rex Wild Attack?
None of the casino game lists available to us names T-Rex Wild Attack, so we can't confirm a specific casino. RTG-powered offshore casinos such as Planet 7, Royal Ace and Slot Madness are the likeliest places to find it, so check their lobbies. Our best RTG casinos page compares the partners that run RTG games.
Can I play T-Rex Wild Attack with free spins from a bonus?
Casino free spins are usually tied to a named game, and none of the offers here names T-Rex Wild Attack in the published terms we have. Deposit bonus funds can usually be used on RTG slots like this one, subject to wagering and max-bet rules. Read the offer's terms for the eligible game. Our free spins bonus guide explains how spin offers work.
Can I play T-Rex Wild Attack on my phone?
Probably, at casinos that carry it, since RTG's recent slots run in mobile browsers. Third-party reviews describe Planet 7 as instant play in Android and iOS browsers with no downloadable app, and list Royal Ace with instant-play, mobile and download versions. None confirms T-Rex Wild Attack by name, so search the mobile lobby before you deposit. The 6x4 grid packs 24 positions into the screen, so landscape mode may make cascades easier to follow. Our Planet 7 mobile page explains its browser setup.
Is T-Rex Wild Attack high volatility?
No volatility rating is published for T-Rex Wild Attack, so it's unknown. Its design hints at swings, though: cascading reels and a free spins multiplier tend to push a large share of the return into a small number of strong bonus rounds, which usually means quiet spells between them. That's an inference, not a rating, so plan as if swings could be large and pick a stake that gives at least 100 spins from your budget. Our volatility explainer shows how ratings affect a session.
How much does an hour of T-Rex Wild Attack cost?
The hourly cost of T-Rex Wild Attack can only be estimated, because its RTP isn't published. Assuming 400 paid spins an hour at $1, you'd stake $400: at an illustrative 95% RTP that's $20 on average, and at 97% it's $12. Cascades don't add to the cost, since every chained win comes from the spin you already paid for; only re-betting wins raises total stake. At $0.25 a spin, the same hour costs $3 to $5. Our casino math basics guide shows the formula.
How does the free spins multiplier work in T-Rex Wild Attack?
T-Rex Wild Attack lists a multiplier that applies to wins during free spins, but its size and whether it grows with each cascade aren't published. That second point matters most: if the multiplier climbs through a chain of cascading wins, one free spin can pay several boosted wins in a row, and the round becomes much swingier. If it's fixed, the effect is steadier. The paytable at your casino states the rule. Our multiplier glossary entry explains how slot multipliers are applied.
What is a Planet 7 bonus worth on T-Rex Wild Attack?
On average, the bonus costs more to clear than it adds, though the exact figure depends on an RTP that isn't published. Using LCB's report of Planet 7's WELCOME200 code, a $50 deposit with a 200% match gives $150 in play, and 30x (bonus plus deposit) means $4,500 of wagering. At an illustrative 4% to 6% edge, that costs $180 to $270 on average, and any win above the reported $1,000 max cashout is removed. Our Planet 7 bonus codes page lists the reported terms.
How long do Planet 7 withdrawals take after a T-Rex Wild Attack win?
Third-party sources disagree, and some report slow payouts at Planet 7. AskGamblers lists a 5 to 7 day pending period, then 7 to 9 days for bank transfers, with no weekend cashouts. LCB flags delayed payments and says payouts usually take more than a month. Withdrawal methods are reported as bank wire, check and Bitcoin, with a $2,500 weekly cap and a minimum of $50 or $100 depending on the source. Verify your ID before requesting. See the Planet 7 withdrawals page for the full picture.
Is it legal to play T-Rex Wild Attack in Pennsylvania?
Pennsylvania does license online casinos, but T-Rex Wild Attack isn't reported at any of them. The Pennsylvania Gaming Control Board listed 12 interactive gaming certificateholders and 25 authorized brands as of February 13, 2026, and RTG isn't reported among the providers at state-licensed sites. The offshore casinos that run RTG games hold no Pennsylvania license, so they sit outside the board's protections. Players in Philadelphia, Pittsburgh and Allentown have legal options. Our Pennsylvania online casinos page lists what the state allows.
What are respins in T-Rex Wild Attack?
Respins are extra spins that replay the reels, usually with some symbols held in place, and T-Rex Wild Attack lists them as a separate feature from its free spins. In RTG games, a specific symbol or event normally triggers them. The trigger and which symbols are held aren't published for this game, so check the paytable. A respin doesn't cost a new stake, but it's part of the game's built-in return rather than a bonus on top. Our bonus round glossary entry covers related features.
