Twister® is a 4-reel, 6-row video slot with the Avalanche™ feature, a Twister Spinner with 4 different features, Free Spins with a progressive multiplier, and the Buy Feature.
Twister Spinners can appear anywhere on the reels in the main game and during Free Spins. When a Twister Spinner symbol lands on the reels, it triggers the Twister Spinner wheel, which consists of 4 parts divided by body parts, with 4 colours in each part. Each body part represents a different type of Wild symbol and each colour represents the intensity of the Wild symbol. If multiple Twister Spinner symbols land on the reels, one Twister Spinner wheel is triggered and spins once for each Twister Spinner symbol that lands on the reels.
Wild symbols substitute for all symbols except Scatter symbols and other Wild symbols. Wild symbols substitute for the highest possible winning combination on the bet method according to the paytable.
Wins are evaluated after all Twister Spinner symbols have been activated and all Wild symbols have been placed.
The Twister Spinner turns into an Upgrade Wild symbol and all low-paying symbols of one type on the reels turn into medium-paying symbols depending on the colour on the Twister Spinner. All low winning symbols of the same type are changed and the feature does not affect new symbols that are avalanche added.
The Twister Spinner turns into a multiplier Wild, the value of which depends on the colour of the Twister Spinner (blue – 2, green – 3, yellow – 4, red – 5). The Wild Multiplier multiplies the number of bet paths passing through it by the multiplier value. Multiplies several Multiplier Wild values.
The Twister Spinner turns into a random Wild symbol and more random Wild symbols are placed on the reels depending on the colour of the Twister Spinner (blue – 2, green – 3, yellow – 4, red – 5 random Wild symbols on the reels). Random Wild symbols cannot be placed on top of other Wild or Scatter symbols. Two random Wild symbols cannot be placed in the same position.
The Twister Spinner turns into a locked Wild symbol that stays on the reels for a set number of avalanches that can appear depending on the colour of the Twister Spinner (blue – 2, green – 3, yellow – 4, red – 5). The Locked Wild feature does not guarantee that a set number of Avalanches will occur, but will remain on the reels for a set number of Avalanches or less (unless there are no other wins on the reels). The Locked Wild symbol can move across the reel during an Avalanche and disappear from the reels after a set number of Avalanches, determined by colour. Locked Wild symbols do not remain on the reels between spins.
3 or 4 Scatter symbols appearing anywhere on the reels in the main game activate 6 or 11 Free Spins, while 2, 3 or 4 Scatter symbols appearing on the reels in Free Spins award 1, 2 or 4 additional Free Spins, after all Avalanches.
At the start of Free Spins, a progressive x1 multiplier appears on the reels, which increases by +x1 for each Twister Spinner that lands on the reels. All wins are multiplied by the current value of the progressive multiplier and this value is increased before any wins are evaluated during this Avalanche. The progressive multiplier remains on the game board until the end of Free Spins.
Free Spins are played with the same bet as the round that activated Free Spins. At the end of Free Spins, the total win from Free Spins is added to any win from the round that activated Free Spins and the game returns to the round that activated Free Spins.
Free Spins can be activated using the Buy Feature for 100x your bet. When Free Spins are activated with the Buy Feature, one free spin of the main game is played with no winning combinations or Twister Spinners and with 3 or 4 scattered symbols guaranteed, which activate 6 or 11 Free Spins.
The longest winning combination of J symbols is 4 symbols on reels 1-4. The number of winning bet ways is calculated by multiplying the number of J symbols on each of the following reels: 3 x 1 x 1 x 3 = 9 winning bet ways.
When Wild symbols form a separate winning combination, the number of winning bet ways is calculated by subtracting the winning bet ways for Wild symbols only from the standard calculation for J symbols and Wild symbols on each of reels 1 to 4. Wild symbols that form a winning combination will only be paid once. In this case, the calculation is as follows: (2+2) x (0+2) x (0+3) x (2+2) – (2 x 2 x 3 x 2) = 72 winning bet ways.
A bet mode win that appears on the reels triggers Avalanche™. Symbols in winning combinations will disappear, making way for a new avalanche of symbols. The avalanches continue until more wins appear on the reels.
