| Updated: September 24, 2025It seems that Crazy Tooth Studio is trying to set itself apart from other iGaming software providers with every online slot it releases. The studio often takes a familiar casino game theme and reimagines it on the reels in a way that makes you wonder where you’ve ended up. This approach tends to generate polarized ratings, but it certainly makes the studio a recognizable brand.
Today we present Rhino Rilla Rex™, a high-volatility online slot with 3,125 ways to win and several bonus features that are sure to catch your eye. Read on to find out more about this quirky dinosaur-inspired casino game and decide whether it is your cup of tea.
The Rhino Rilla Rex™ Theme, Graphics, and Sounds
Once you enter the jungle of the Rhino Rilla Rex™ slot, you will hear sounds you never imagined existed. They are produced by futuristic beasts and other creatures that inhabit a dark, distant world. Instead of the cheerful little monkeys we are used to seeing in other jungle-like online casino games, this slot features rampaging gorillas alongside hybrid dinosaurs and menacing rhinos.
When one of the premium beast symbols appears on the reels, its corresponding roar is heard, and the spins themselves sound like falling rocks. Exploring the Rhino Rilla Rex™ slot is definitely a bizarre experience, and that feeling extends to its payouts and bonuses, so let’s move on.
The Rhino Rilla Rex™ Symbols and Payouts
While some aspects of the slot may be complex, forming winning combinations is not. All you need to do is land between 3 and 5 identical symbols on adjacent reels, regardless of the row. The game’s math model offers as many as 3,125 ways to land a winning combo. If two or more winning sequences appear, only the highest one pays.
When calculating prizes, way wins and credit awards are multiplied by the stake multiplier for the current game round. This multiplier equals the number of credits you have chosen to play with divided by 0.25. Don’t worry if this sounds complicated. The slot software automatically recalculates your potential win after each bet change, so you don’t have to do a thing.
Now, let’s discuss the symbols you will encounter on the reels. Given the slot’s name, it is not surprising that the three premium icons are the Rhino, Gorilla, and Rex. Each of them pays 0.08x your stake whether you land 3, 4, or 5 symbols – a rather unusual setup. The same approach applies to the other four symbols – purple, blue, red, and green paw prints belonging to the three beasts. Their payout is even lower – just 0.04x the amount wagered.
There is also a wild symbol, a colorful and easily recognizable icon. It appears only on reels 1 and 5 and substitutes for any paying symbol if it helps create a winning combination.
The Rhino Rilla Rex™ Bonus Mechanics
Like the other elements of this slot, its bonus mechanics are highly specific and unlike anything typically available on the market. First, there is the Team-Up Feature, which is activated when 3 or more premium symbols land fully in view (Full Stack Feature Symbols). When this happens, the corresponding symbols combine and a hybrid creature comes to life on the grid. It assigns a multiplier, and then a new game grid is created. The new reels contain credit prizes, multipliers, and tokens. Players receive a single spin and collect the sum of all cash prizes shown, multiplied by one of the x2, x3, x4, or x5 multipliers if any appear.
Next comes the Team-Up Bonus Spins feature, which, as the name suggests, is somewhat similar to the previous one. Free spins are triggered when at least three beast symbols land fully in view, with at least one surrounded by a golden “bonus” frame. As before, these special symbols generate a new game board. Cash prizes, multipliers, and extra spins may appear on the reels. There is no upper limit to the number of respins within a single Team-Up Bonus Spins round.
When you load the game on your preferred device, you will see a separate field with four progressive Beast Prizes. A meter with a different number of slots sits beneath each prize, and whenever a premium animal symbol lands fully in view, the value of its corresponding prize increases. Each token obtained through the Team-Up Feature or Team-Up Bonus Spins fills one of these slots. The seed values for five purple, six blue, seven red, and eight green filled slots are 5x, 25x, 100x, and 500x, respectively. The maximum you can win is 5,000 times your bet multiplier.
Closing Thoughts
The Rhino Rilla Rex™ slot bears Crazy Tooth’s distinct brand of entertainment, with certain aspects that impress and others that are less inspiring. Although low symbol values are not unusual in a Crazy Tooth game, this title certainly stands out. This drawback is somewhat offset by the fact that there are 3,125 ways to win, i.e., you can expect relatively frequent, albeit modest, payouts. Furthermore, if you have plenty of patience, you may still collect sizable amounts from the Beast Prizes feature.
