The Rainbrew online slot has many features, including innovative mechanics, making the slot game more engaging. They may not be as widely varied as some of the other slots; however, the Sidewinder feature more than makes up for any extra bells and whistles.
Sidewinder feature
The Sidewinder feature is a reel format unique to this game. It has the ability to increase the ways to win from 243 to 1,125. The Sidewinder feature consists of two horizontal tubes above and below the middle reels, which spin independently from the main reels.
You need the Top Wild and Bottom Wild symbols to activate this feature, which can trigger one or both tubes to spin, adding extra wilds or free spin symbols to the reels.
If you can get both tubes active simultaneously, the game window is expanded to a 3-5-5-5-3 format with 1,125 ways to win. With Sidewinder, you have the chance to create more winning combinations and land bigger payouts.
Free spins feature
The free spins feature is activated when you land three or four free spins symbols on the reels. The free spins symbol is a rainbow-coloured ale that can appear only on the horizontal tubes and second and fourth reels. Landing three free spins symbols awards six free spins, while four symbols award 10 free spins.
Both horizontal tubes are always active during the free spins, and any wild symbol that lands on them will expand to fill the entire reel. If a wild lands in the same position on both tubes, it will connect and create a wild reel.
During the free spins, you can retrigger them by landing one free spin symbol on each horizontal tube, which gives you an extra spin for each symbol.
