The Twin Wins Mystery RTP and Volatility

7.5 

The Twin Wins Mystery’s RTP rate is set at 95% and its volatility is very high.

The Return to Player rate of this slot is set at 95%, which is slightly below the industry's average of 96%. The volatility of The Twin Wins Mystery is very high, which means that it will provide a good challenge for players, as it will be harder to get a winning combination, but the payoff for said combination will be a lot bigger than in slots of other volatility levels.

Theme

10 

The Twin Wins Mystery is… a mystery. To be specific, it is a slot that combines the mystery elements with horror, specifically ghosts, to create a very unsettling but amazing vibe. Everything in this slot is made to reflect the creepy aspect of the central theme, from the haunted house-like music in the background with occasional ghost screams, to the overall design of The Twin Wins Mystery. And we have to say, the overall design is really well-made, with a detailed background and reels and very cool-looking symbols.

And speaking of, let’s take a look at the symbols in more detail! There are both regular and special symbols. The regulars are the symbols from the playing cards – J, Q, K, and A. Then there are symbols of the mirror, a book with a pentagram, a triangle-shaped box with an eye, a teapot, and the Fabergé egg – the most valuable regular symbol in the game.

The special symbols are the Wilds and a Scatter. The Wild symbol is the twins, and it will substitute all symbols, except the Scatter. Moreover, Wild can randomly award you with special Multiplier Pins that you can collect and use in the Free Spins feature. These Multiplier pins will be collected in a pincushion skull next to reels.

The Scatter symbol is a doll, and it will trigger the Free Spins feature if you collect a certain amount of these symbols.

  • three Scatters – 10 free spins
  • four Scatters – 40 free spins
  • five Scatters – 100 free spins

We should also note that there are also 2 symbols, exclusive only to the Free Spins mode – the Wild Twins Giant symbol and Voodoo Doll. The Wild Twins Giant symbol will cover the cloned reels 1 and 2, and it can substitute all symbols except the Ragdoll multiplier.

The doll Scatter will change to a Voodoo Doll symbol during Free Spins, and it will only appear if the Wild Twins giant symbol is present on reels 1 and 2. If the doll lands on top of a symbol where a Pin or Pins have been placed, it will multiply any wins through that symbol space by the total multiplier amount pinned to that space.

Bonus Rounds & Free Spins

7.5 

Free Spins

Once you collect 3–5 Scatters you will be awarded the Free Spins feature. Once it’s triggered and before Free Spins start, you must first place all the collected Multiplier Pins collected to any of the nine symbol spaces on reels 3–5. You’re free to choose how many and which pins you want to place. Keep in mind that the feature will not start until you place the Multiplier pins and confirm.
In this feature, the reels 1 and 2 will be identical and will spin together, and it is during the Free Spins feature that you will encounter exclusive symbols: Wild Twins Giant and Voodoo Ragdoll. The first symbol appears only across these two identical reels, and any time that Wild Twins appear in a spin they will snap into place if only partially shown. The Wild Twins Giant will first substitute for any line wins and will make Voodoo Ragdoll appear over reels 3–5.

Max Win

7.6 

The maximum you can win in The Twin Wins Mystery is 5,740x your bet.
