Expert review
The Queen Halloween slot machine could be a good choice for players with little casino experience. While it’s not considered a classic due to its immersive graphics and animations, its gameplay is very close to that type of slot.
The slot has medium volatility, allowing your betting balance to fluctuate smoothly and remain roughly constant. This is an advantage when using the slot to wager bonuses.
Although payouts are awarded only for matching combinations of symbols on lines, the potential payouts are quite large. The minimum multiplier is x0.2, and the maximum is x900. Moreover, multiple winning combinations can form in a single spin.
What do you know about casino bonuses?
The slot’s RTP is 97.3%, which is also a plus. This is high compared to the market average. Therefore, the Queen Halloween video slot is a great choice for regular play.
Basic betting mode
The game takes place on a field of five reels and three rows. There are 10 paylines, along which winning combinations are formed. This number can be reduced to just one. To receive a payout, two or three identical symbols must line up on a line, depending on the denomination. Combinations are formed in only one direction—from left to right.
The payout range is very wide. The minimum win is just 0.2x for two nines and tens. The maximum multiplier reaches x900 if a line of five wild symbols forms. Wild symbols have only one function: they substitute for all other symbols except the scatter.
After receiving your payout, you can try to increase it. A risk game is available for this purpose. To activate it, click the “x2” button at the bottom of the interface. Here’s how this mode works:
- A face-down card appears in the middle.
- The user must select a color—black or red. The map then opens.
- If the player makes the correct choice, the payout is doubled. Otherwise, it is lost.
This action can be repeated multiple times. There’s a chance to double your winnings several times in a row. However, the first mistake will result in your winnings being cancelled.
Risk game with card color selection
There are no other mechanics in the basic betting mode. This makes the gameplay as simple and close to the original as possible.
Free spins
Free spins are activated by the second bonus symbol—the Scatter. While it doesn’t contribute to winning combinations, it does award winnings on its own when landing two or more. The position of the Scatters on the reels isn’t taken into account. Landing 2, 3, 4, and 5 of these symbols awards x2, x5, x75, and x750, respectively.
Wheel of Fortune Bonus Free Spins
If at least three Scatters appear during a spin, the Free Spins feature is activated. Here’s how it works:
- The playing field is cleared and a frame appears in the center of the first reel.
- Next, one random symbol is selected except for the scatter.
- This sign is lined up in the central row in the amount of 2 or 3 pieces.
- The remaining cells are filled in and the user receives a payout.
The main feature of free spins is a guaranteed win with every spin. Basic multipliers apply to symbols, so the minimum payout is 0.2x.
Free spins in the slot
The bonus game can be extended by landing at least three more scatters during the round. Free spins cannot be purchased. They can only be activated in the basic betting mode.
