Number 7 has always been associated with good luck, so Ainsworth have added this into Stormin 7’s to give that lucky element to the reels. It is the only slot machine based on this lucky symbol as other titles from the company focus on animal-related themes of diamonds.

Ainsworth’s catalogue of slots offer high roller games to suit players who wish to bet big stakes with the potential to win some heart-stopping amounts of cash in return. Other titles offered by the company include; Twice the Monkey, King Chameleon, Flying Horse, Eagle Bucks and Wild Fire Riches.

Featured Design

The design of this slot game is based on all the things in life that could be lucky to you, so you will find symbols on the reels such as casino chips, playing cards and dice. Other symbols include red hot 7’s, diamonds, dollars, wads of cash, and card values 9, 10, J, Q, K and A. Behind the reels is an electric blue colour scheme – this is to resemble the bolts of lightning which surround the slot game logo. The reels themselves are carved into gold bullion and offer detailed information on how to play to the lower of them.

Navigation is made easy thanks to the simply ‘i’ button that allows you to view the paytable and rules on how to play. To adjust your bet at any time, you use the left and right arrows above the bet per line and paylines. Your balance, total bet and wins will be shown at all times.

If you want to sit back and watch the wins fall on the reels, click the grey section to the top of the red spin button – this will initiate 100 automatic spins. You can take back control whenever you wish by clicking the spin button once more.

Slot Game Info

There are 5 reels and a staggering 100 paylines to the Stormin 7’s slot game. The paylines are adjustable to suit your needs, but the more you have in play, the more chance you have of winning. Stakes allow you to play from 0.01 a line (1.00 for all 100) up to 100.00 a spin (10,000 for all paylines). This slot game has been designed with high rollers in mind as it offers a substantial jackpot and other large payouts.

Five of the Diamond symbols will release the 1,000,000 jackpot with the flaming hot 7’s rewarding you with 75,000. Playing cards, dice and the wad of cash offer the same amount of 15,000 with the casino chips offering 12,500. All other symbols offer a break even on 10,000 stakes.

Lucky Lines

The diamond symbol is your scatter and it is this that will trigger the free spins bonus. Three or more and you will be awarded 10 free spins. The dollar symbol will become the scatter during your free spins and substitutes for all other symbols bar the Stormin’ symbols. Three or more dollars during free spins will award 5 more free spins. Take notice of the paytable as it shows that the symbols offered during the base game will have a lower value attached to them whilst taking part in free spins.

If you can trigger a Stormin 7’s symbol on at least two reels, during the free spins, you will be awarded a free respin. A new Stormin symbol will appear with either a 2x or 3x attached – you will be awarded that stated multiplier to any wins on the reels.

During the base game, the dollar substitutes for all other symbols except scatter, to complete any winning paylines that may have otherwise been missed.

Our Thoughts

Stormin 7’s slot machine is nothing out of the ordinary for Ainsworth as they have a talent in creating slot games with limited features, but with big paying possibilities. The free spins is where the big money comes from – thanks to the Stormin 7 multipliers. We found this slot game to be of medium to high variance with a return to player (RTP) percentage of 93.83%.
