Sidewinder by Microgaming is a video slot game introduced to the casino online market in September 2018.  The slot feature responsible for the expansion of middle 3 reels and respective winning ways is the main theme of the slot. The bets are fixed at 10 coins per spin. Coin values vary from 0.01 to 10 credits. Hence, the min bet is 0.1, and the max is 100 credits.

Learning the Gameplay

Activation of the Sidewinder feature may activate a horizontal reel (say ‘HR’) at the top of the 2nd, 3rd, and 4th reels or at the bottom or in both locations at the same time allowing either wild or scatter symbols to appear as per the triggered symbol. However, the free spin games allow both symbols to land. The default format is 5 reels by 3 rows. Activation of either ‘HR’ changes the format to 3-4-4-4-3, or in case of both reels, the format becomes 3-5-5-5-3. The ways to win subsequently increase from default 243 to 576 or 1,125 respectively.

  • Base Game Wild Symbols. The base game provides 3 wilds each with ‘Wild’ label – regular (rainbow-coloured), top (up arrowheads), and bottom (down arrowheads). The regular wild appears on both ‘HR’, the top one on the 2nd reel with the bottom ‘HR’, while the bottom wild at the top of ‘HR’ lands on the 4th Only a top wild can start the horizontal reel at the top, while the bottom one triggers the bottom horizontal reels. The ‘HR’ (top or bottom or both) triggered by wild symbols will contain wild symbols only. Hence, the activation of the ‘HR’ facilitates more wilds to stop.
  • Base Game Free Spins. The free spins feature can also be activated by the scatter symbols (‘Sidewinder’ Logo). They are found on the 2nd and 4th reels only. When that happens, both (top and bottom) ‘HRs’ are activated to land free spin symbols only. 3 or 4 free spin symbols appearing on the screen offer 6 or 10 numbers of free spins respectively.
  • Free Spins & Expanding Wilds. The free spin gameplay offers 1,125 ways to win as both top and bottom ‘HRs’ will remain activated at the same time. However, regular wilds and scatter symbols of free spins will appear here. The expanding wild feature occurs when regular wilds appear in the same positions at the top as well as at the bottom of the ‘HR’. That entire reel will be filled with regular wilds. With every free spin symbol appearing on the ‘HR’, one bonus spin is awarded.
