Tornado: Farm Escape was released by NetEnt back in 2015. The game used a fun barn animal theme that are being sucked up by a tornado.
On any spin a cloud could appear making one or more symbols wild. A full screen of wild symbols was possible.
Tornado: Farm escape also came with a unique free spins feature.
When you got the bonus symbols on reels 1 and 5 at the same time you would start this bonus.
Before free spins would start, the middle symbol on reel 3 would act as your special bonus symbol. During each spin this special symbol and any wild symbols that would appear would be collected and reward a prize.
The more symbols you collected the higher the value would become.
If a wild symbol was your special bonus symbol, the bonus would only collect wild symbols. Free spins would end when no new bonus and/or wild symbol could be collected after a spin.
Tornado: Farm Escape was a very nice game with a unique bonus. But to be honest, the only real nice wins appeared during the random wilds or free spins feature. And even the free spins weren’t a guarantee for a nice win and could end with only a couple of spins.
But the free spins feature did appear quite often, more times than on other slot games it seemed.
The game was probably discontinued in 2018 due to a lack of interest and popularity.
