Go back to the land of the dinosaurs in the Raptor DoubleMax slot, an innovative 5 reel, 25 payline game from Yggdrasil Gaming that comes with some unusual extras.  Each win triggers a symbol cascade. The winning symbols are removed and a wild symbol is added. Successive cascades also double the value of a win multiplier. Trigger the Free Spins feature for up to 16 free spins. The doubling multipliers are active here too. Better still, the multiplier doesn’t reset following a winless cascade, it continues to rise throughout the feature. With 20,000 x stake max wins, find out all you’ll need to know in our complete Raptor DoubleMax review.

The Raptor DoubleMax slot is played on 5 reels, 3 rows and 25 paylines. Create winning combinations by landing 3, 4 or 5 matching symbols or wilds from left to right on a payline, starting from reel 1. Winning combinations trigger symbol drops which I’ll look at in detail in the Bonus Features section below.

The Raptor DoubleMax RTP is 96.01% which is about average. What most certainly isn’t average is this slot’s variance. The volatility is extremely high. The hit frequency rate is 30.5% so on average, you can expect to land winner on just under a third of spins. The most you can win here is 20,000 x your total stake from a single spin.

Theme – Audio & Design Features – roam the earth in a lost land

Theme: Prehistoric/Dinosaur

High Value Symbol: T-Rex

Compatibility: Mobile, Tablet, Desktop


With a prehistoric/dinosaur theme, the design in the Raptor DoubleMax slot is in very impressive. Dense jungle foliage forms the backdrop to the reels. There’s an energetic soundtrack pumping away while you spin.

On the reels you’ll find A to J royals and 4 higher paying dinosaur symbols (Parasaurolophus, Velociraptor, Triceratops and Tyrannosaurus Rex). The best paying symbol is the roaring T-Rex which pays 0.8, 2 or 5 x your total stake if you land 3, 4 or 5 across a payline.

The fossil is the wild symbol. This can land on all 5 reels and substitute for all the standard symbols when it makes up part of a winning combination. Finally, there’s the dinosaur egg which is the scatter symbol. This can trigger the main bonus feature. Find a list of all symbols below with payouts and information:

Raptor DoubleMax Mobile


Yggdrasil Gaming has created versions of Raptor DoubleMax that have been fully optimised for play on all devices including mobiles, desktop computers, laptops and tablets. They all offer the same blend of classy design and super volatile gameplay.

Raptor DoubleMax Bonus Features

The theme here might be prehistoric but the features in Raptor DoubleMax are bang up to date. Cascading reel wins, added wilds, expanding multipliers and free spins mean there are plenty of opportunities for T-Rex sized action. In total, there are 4 bonus features.

Cascading Reels feature

Each time you land a winning combination, the Cascading Reels feature applies and a symbol drop follows. The successful symbols are removed from the grid and new symbols drop in and replace them. Among that number of new symbols will be a new wild. A new payout consideration then follows with the new symbols in place. The symbol drops (and extra wilds) keep on coming as long as a new winning combination is on display.

Doubling Multiplier feature

Each symbol drop win also activates the Doubling Multiplier feature. It doubles the value of a win multiplier. The multiplier only resets when you have a drop where no new winner is formed.

Free Spins feature


Land 3 or more dinosaur egg scatter symbols anywhere on the reels on the same spin to activate the game’s Free Spins feature. The more scatters, the more free spins. 3, 4 or 5 scatters will award 8, 12 or 16 free spins respectively.

Once triggered, you’ll have the opportunity to gamble and try and improve your allocation of free spins. It’s a 50/50 shot if you gamble from 8 to 12 free spins and 25/75 if you try and go from 8 to 16. Lose the gamble and you’ll return to the base game.

The free spins start with payout at the standard 1x rate. The symbol drop wins are active here just like in the base game. Each win doubles the value of the multiplier. The big difference is that the multipliers do not reset following a winless symbol drop. They remain the same or increase throughout the feature. Get on a roll here and the multipliers can get very big indeed.

Golden Bet feature

You can boost your chances of triggering the Free Spins feature by activating the Golden Bet feature. This increases your standard stake by 25% but doubles the chances of landing the free spins. In some territories, players will also have the chance to buy the Free Spins feature for a fee of 100 x your total stake.

Raptor DoubleMax Review Summary – a super volatile dinosaur adventure

Bonus Features

RTP (96.01%)

Max Win (20,000 x)


The dinosaur theme is a popular one but there aren’t many games that comes with gameplay like the Raptor DoubleMax slot. The symbol drops with added wilds and doubling multipliers can really ramp up the action. Be warned tough. The volatility is extremely high so approach with caution.

The key to big wins is from the doubling multiplier in the free spins which can only increase. Get on a good run of cascades and you could benefit from huge multipliers. This is where the maximum 20,000 x stake wins will come from.

Overall, Raptor DoubleMax is a good game with frequent action. Just hope the doubling multipliers work their magic during the free spins. If you like the dinosaur/pre-historic theme, Playtech’s Jurassic Island 2 comes with a Wild Trail feature where you final free spin can benefit from 5x multiplier wilds. This can lead to 23,290 x stake max wins.

Another option is Jurassic Park from Microgaming which offers 5 free spins features, is an official branded game and offers 6,333 x stake max wins.

  • Big 20,000 x stake max wins
  • Superb doubling multiplier in free spins
  • Superb design
  • Very high variance
