The Sumatran Storm slots game has been making waves at online and mobile casinos ever since it was launched back in 2013. The five reels are in a hexagonal layout and you will discover 720 ways to win running across them. Sumatran Storm comes from the studios of International Game Technology (IGT) and uses their popular MultiWay Xtra payout system to help you grab easy wins and multipliers.
The online video slot is based on the island of Sumatra, in Indonesia, although the link is tenuous at best. A Sumatran Tiger is the star of the show, joined by a tiger claw decoration, blue necklace and the playing card symbols that have been seen on so many slots before, and we’re sure will turn up on many slots in the future.
Don’t let the lack of imaginative symbols put you off though, The Sumatran Storm online slots game has become a huge success, thanks to the potential for big wins and the exciting features. Wild substitutions and the chance to trigger up to 150 free spins are the highlights. Land the ideal combination of symbols at the highest stakes and you could walk away with a massive prize of 500,000.00.
Sumatran Storm is optimised to work across iOS and Android mobile platforms, as well as on desktop computers, so however you want to visit the reels, IGT have it in a format to suit. Check out our review, then play the Sumatran Storm slots game at some of our top online slots sites.
This is an easy game to set up, so no matter how much or how little experience you have with slot machines, you can be playing in seconds. Click a button to raise or lower the stakes, from the minimum of 0.60 per spin to the maximum of 30.00 per spin.
Before you start to play, it’s a good idea to look at the MultiWay Xtra system. You win by landing 3, 4, or 5 matching symbols across the reels from left to right and right to left. The number of rows on each reel varies, with a 3-4-5-4-3 layout giving the game a hexagonal shape. Prizes will be multiplied by the coin value and if more than one example of the winning symbol is on a reel, the win will also be multiplied.
Take a look at the paytable to see what each symbol is worth. While you can expect frequent payouts when the playing card symbol appear, these will be lower in value, so what you really want is to see the themed symbols landing across the reels. The Sumatran Storm game logo is the most rewarding, with prizes equal to 60, 150, or 1000 coins when it’s seen on 3, 4, or all 5 reels.
The betting options and special features work in exactly the same way when you play on iOS and Android mobiles, desktop PCs and laptops. The option to enjoy Sumatran Storm on any device is one of many reasons that so many people play this exciting game.
The hexagonal reels are set against an attractive backdrop of the Sumatran jungle. The green and brown colours that you would expect to find have been replaced by an eye-catching red, orange and purple palette. Some of the symbols, especially the tigers, are in stunning, almost photo-real, detail.
Alongside the standard symbols, the Sumatran Storm slots game features special bonus symbols. A tiger is wild, which doesn’t mean that it hasn’t been domesticated, it means the symbol can act as others to help complete combinations. The wild symbol only appears on the middle 3 reels though, so can’t pay out anything on its own.
A scatter symbol pays 2x, 10x, or 50x the total bet when it’s seen in any 3, 4, or 5 places. It’s usual for scatters to trigger bonus games, but in this case, you need to land a tiger eye symbol across all 5 reels to enter a free spins round.
Each combination of tiger eyes that appeared in the triggering spin will award 5 free games. You could see just 5 spins playing out, or as many as 60, but in our experience, 10 – 20 is usual. The free games can be retriggered over and over by more tiger eye symbols appearing across the reels at any point, with an absolute maximum of 150 spins.
We found this to be a medium volatility slots game, where the frequency of prize-winning spins is nicely balanced by the overall size of payouts. The Sumatran Storm slots game has a return to player percentage of 93.23%, which is a little less than we like to see.
This slot would perhaps have benefited from a closer link to the theme, with the playing card symbols replaced by Sumatran artefacts. But apart from this minor detail, we are happy to give Sumatran Storm our seal of approval.
The MultiWay Xtra system is an exciting format that IGT has rolled out across many of their top games. It can lead to the highest payouts when you have several matching symbols across the reels as well as in more than one place on each reel.
If you like tigers, be sure to play the Golden Jungle slots game, which is another IGT release. It’s a conventional 5-reel, 50-line slot, set in India, where the reels fill with precious jewels, crowns and treasure boxes. The tiger is a double-height wild symbol, worth up to 2000x the line bet, while a golden statue can turn whole reels wild for the next 3 spins.
Both of these great-looking games can be found at some of our favourite IGT-powered online and mobile casinos. Be sure to get your claws on the free casino bets waiting for you when you join a recommended site.
