Rex Stampede: Slot Overview
Software provider ELK Studios has fired up its virtual time machine to travel many millions of years into the past to a time when dinosaurs stomped the earth, and survival could be a brutal task. The slot is Rex Stampede, and as well as featuring big dangerous beasties of yesteryear, the studio introduces a 'mythical beast of unsurpassed power and fortune' - a golden T-Rex, which is integral to expanding the gaming area and upgrading lower value premium symbols to the highest value. So, if potentially being stepped on by giant reptiles or scooped up in cavernous jaws doesn't put you off, it's time to brave ELK Studio's dangerous prehistoric world.
Around the time of writing, a debate had ignited the internet about whether 100 unarmed humans could defeat a single gorilla in a physical fight. If we expand the hypotheticals to an even bigger, scarier adversary, how many humans would it take to bring down a single T-Rex in unarmed combat? Could it even be done? Perhaps in a distant future, when scientists have brought dinosaurs back Jurassic Park style, some dystopic society will use them in a bizarre, twisted form of gladiatorial games to solve the question once and for all. Rex Stampede goes in the opposite direction on the timeline, to a far distant past when big lizards ruled, and land mammals were inconsequential nobodies that better move quickly to avoid being devoured.

Facing the stampede means choosing a stake of 20 c to $/€100 per game round. Hidden away like a little dino embryo is Rex Stampede's highly volatile math model, generating an RTP of 94% whether betting on regular spins or when engaging the X-iter feature buys. Hit play, and a 5x4 gaming grid spins and creates winning combinations from the leftmost reel evaluated by 1,024 ways to win. The grid can add two extra positions to reels 2 to 5, resulting in up to 5,184 ways to win.
Prehistoric yet colourful 10 to A card ranks are Rex Stampede's low pay symbols, awarding 0.2x to 0.4x for a 5 OAK combination. Equally prehistoric but a lot more terrifying are the five high-pay dinosaur symbols, with T-Rex as the most valuable, awarding players 1x to 8x their bet when a 5 OAK premium combination hits. Each payout symbol may be stacked, displaying a number which represents how many symbols occupy the specific symbol position. Wild symbols substitute everything except scatters and Stampede symbols. When a wild participates in a win, it may reveal a multiplier of x2, x3, or x5.
Rex Stampede: Slot Features

Get ready for some virtual ground shaking caused by features such as Stampede, free spins with expanding reels, and a group of X-iter bonus buys.
Stampede
If 2 or more Stampede symbols land in the same row, the Stampede feature triggers, affecting all rows with 2 or more Stampede symbols. The Stampede symbols plus the regular pay symbols between them get transformed into T-Rex symbols in the base game and golden T-Rex symbols in the bonus round. Stacked symbols transformed by the Stampede become stacked T-Rex symbols in normal mode or golden T-Rexes in bonus mode.
Free Spins
Landing 3, 4, or 5 scatters awards 6, 12, or 18 free spins, respectively. During the feature, hitting a Golden T-Rex on the leftmost reel awards +1 free spin. Hitting a golden T-Rex on any reel except the leftmost awards +1 token for that reel. Golden T-Rexes in these situations then convert to regular T-Rexes. Collecting 3 tokens on the same reel adds +1 free spin, expands the reel from 4 to 6 rows (revealing T-Rex symbols), and all matching high-pay symbols indicated above the affected reel transform into T-Rex symbols. This state remains for the remainder of the feature. In addition, when a wild participates in a win, it will always reveal a multiplier, and wilds between Stampede symbols count as golden T-Rex symbols. Lastly, hitting 2, 3, 4, or 5 scatter symbols triggers an extra +3, +6, +12, or +18 free spins, respectively.
X-iter
The X-iter is where players can activate the Bonus Hunt at 3x the bet, which buys 1 spin with more than triple the chance of triggering the bonus round. The Two or more Wilds mode costs 10x, causing at least 2 wilds to land per spin, or players can guarantee a Stampede trigger for 25x. The regular bonus round can be bought for 100x or the super bonus at 500x, where every spin triggers a Stampede.

Rex Stampede: Slot Verdict
Anyone who has seen the film Jurassic Park knows how dangerous a single T-Rex can be, so a stampede of them would surely be too much for a group of terrified, unarmed little bipeds to handle. However, in Rex Stampede, stampeding herds of furious T-Rexes is a highly desirable occurrence due to the simple fact that it is the game's highest-paying symbol. In fact, Rex Stampede is built around trying to get as many T-Rex symbols onto the grid as possible, and there are several ways the game can possibly do this - or tantalise with the thought of doing so.
The Stampede feature is one way of doing so, and this feature is available at all times, both in the base and bonus game. Stampede symbols can also hit on the leftmost reel, so the feature can instantly create wins, though there is no guarantee where these symbols will land. Furthermore, in normal mode, if an already stacked symbol converts to a T-Rex, the new T-Rex symbol retains the stacked value, potentially powering up the result even further. Golden T-Rexes are even more valuable in free spins since they create tokens that can expand reels and transform lower high pays to the highest T-Rex symbol. It's not for nothing that super free spins, which guarantee a Stampede on every spin, provided the most exciting moments during the test sessions.
With a win cap of 25,000x the bet, there is plenty of theoretical room for Rex Stampede to get its roar on. It's a vibrant game, brightly coloured, full of thundering beasts, and its mix of reel expansion and symbol transformation might be just as enticing for dino-philes as it is for players into Pink Elephants/Eye of Horus-type gaming with some additional extras attached.
In Short
For symbol upgrade enthusiasts, Rex Stampede presents a bold, thundering option.
