Tornados are devastating natural phenomena. But they are often portrayed in a lighter vein. The classic example is of Dorothy in The Wizard of Oz. There are some online video slots that are based on tornados or twisters as they are also referred to.

Triple Twister is from Realtime Gaming and live at online casinos like Club World. Twister is the wild symbol. It appears only on reel 3 but makes up through its other properties. It expands to cover the reel, triples payouts and also substitutes for the scatter symbol. Tornados are rural occurrences, so the symbols include farmer, his wife, barn, cow, pig, dog, windmill, tractor, van, bucket and hay. The scatter symbol is the weather vane. It awards payouts multiplied by the total bet and trigger 9 free spins. The twister symbol moves onto 1 or 2 additional reels in this feature. Triple Twister has the popular Realtime Gaming Win-Win feature and the twin randomly triggered progressive jackpots. It is a fixed 50 paylines online slot.

Tornado: Farm Escape is from NetEnt and can be played at online casinos like InterCasino. It is loosely based on the 1996 hit movie Twister. The high paying symbols are the farm animals like cow, horse, pig, goat and hen. In the win animations they can be seen lifted in the air by the tornado. The low paying symbols are household items. The television set that brought the news of the tornado is the wild symbol. The Tornado Feature collects the wilds and the symbols from the central reel and awards payouts depending on the symbols collected. In the Storm Feature the storm starts from one of the outer positions on the reels and generates a trail of wild symbols.

Twister from Microgaming is available at online casinos like Royal Vegas. It is a simpler video slot. The twister is the wild symbol and it also awards the top line payouts. It tries to look menacing, especially in the win animations. The television set awards scatter payouts and 20 free spins in which all payouts are doubled. The high paying symbols are three zany characters – a cigarette smoking grandmother, a tipsy blonde and a hillbilly with front teeth missing. The low symbols are the characteristic playing card icons. You can activate the gamble feature after any winning spin. If you guess the colour of the card then you double your staked amount, otherwise you lose it. Twister is a 5x3 video slot with 15 paylines.
