Free play slots are the best way to find the right game to enjoy during your free time. After all, the most important thing is having fun – and decent payouts, of course! So, prepare for a trip to the intense jungles of Sumatra! Furthermore, you can also give a check to the other slots that you can play for free.

Sumatran Storm Demo Slot

The graphics in Sumatran Storm aren’t overly spectacular, but they have a nice classic feel to them. The sound effects really do help in building the atmosphere – but the true highlight here is the unique layout and the 720 Ways to Win feature.

If you are enjoying the payouts and the gameplay, then you should definitely try to play it for real money! Nothing can replace the thrill of the win, especially when you have to stare in the eye of the tiger to claim it.

We’ve prepared a thematic casino suggestion for you – what better place to find a tiger than the lion’s den in Karamba – one of the best Sumatran Storm casino sites around.

On a more serious note, Sumatran Storm is a relatively rare slot, so out of our list of top casino sites, this really is the best casino that has it on offer.

Sumatran Storm Slot Overview

Sumatran Storm is a unique slot game as it breaks the usual 5×3 format. You have the usual five reels, but the rows are not with equal width, but rather form a diamond pattern.

This would be a bad thing if there were paylines in the slot, but here we have a modification of the well-liked 243 Ways to Win system.

This means that matching symbols simply need to appear in neighbouring reels, and this is enough to form a winning combination. Here you have the added bonus of right-to-left wins (Multiwin Xtra), which actually increases the possible combinations to the impressive 720.

Basically, this means that you have 720 paylines always active. The veterans from IGT have provided you with a straightforward interface that we have seen in many of their games, but it is somewhat lacking – for instance, you don’t have any fast-play options which can be unnerving if you don’t want to watch the visual effects.

Sumatran Storm Payouts and Symbols

This slot takes you on a trip to Sumatra, one of the most exotic places on Earth. The theme is a much warmer continuation of the freezing landscapes that we saw during Siberian Storm.

You can find rare treasures in Sumatra and meet a ferocious tiger – an endangered species by the way, help spread the awareness for these wonderful animals! However, the highest-paying symbol is the game logo; five of those net you this slot’s jackpot.

You also receive payouts from the Scatter symbols who don’t have to form a winning combination, but unfortunately do not trigger any special effects either. Instead, there is a special symbol – the Eye of the Tiger – which triggers the free spins in this game.

With the tiger theme strong as it is, you should consider this animal your lucky charm here – a tiger’s silhouette acts as a Wild symbol and appears stacked on the reels. Those are very useful when they come up in the long central reel, as a Wild there can increase your winnings significantly.

Sumatran Storm Paytable
Advantages:
  • Multiway Xtra Win
  • 720 Ways to Win
  • Unique Layout
  • Classic Graphics
  • Intense Sound Effects
  • Bonus Free Spins
Disadvantages:
  • Few Free Spins
  • High Minimum Bet

Sumatran Storm is a very easy game to play. Since there are no paylines, your bet is fixed at 60 coins. You simply need to adjust the size of the coins, and you’re good to go.

Most casinos allow for rather high maximum bets which makes the game a good pick for high-rollers, but there is also a drawback – the minimum bet is set at £0.60. This is actually rather steep and would be bad news if you’re preparing for a long, relaxing night with a slot.

Most games allow you to place 20-25 pence bets or even 1 penny for a single payline. Still, this is the price to pay for the more frequent payouts you get with the Multiway Xtra feature.

Sumatran Storm Slots Bonuses

Compared to the innovative base game, the bonus rounds here come out as somewhat dull. There are several special symbols, but the Eye of the Tiger is the most important. If you land those of all five reels, then you receive 5 bonus free spins.

This is actually a rather small number, especially considering how hard it is to have the symbols on all 5 reels. The only good news is that there are a lot of stacked symbols in the game. This means that if you are really lucky, you can get up to 60 spins. Furthermore, the bonus can be retriggered during the free spins themselves.

In most cases, the bonus does not land often enough, and 5 spins don’t pack quite a punch compared to other games. All to all, for all its hype the Eye of the Tiger, pales in comparison with the innovative base game.

However, there is something that most people miss here. The upper limit of 60 free spins is very high, especially considering the frequent payouts. If you manage to trigger more than 5 spins, the bonus suddenly becomes immensely good. This can bring the expected Sumatran Storm RTP rate of the game up to 96.56%, which is in the high end for slot games as a whole.

Sumatran Storm Mobile

Mobile gaming is the future of the online casino industry. However, most operators have so many diverse slots in their catalogues that they haven’t yet managed to make them all compatible with mobile devices.

Sumatran Storm is not an old title per se, but it still hasn’t gotten a revamp. It can start on some devices, especially tablets, but the experience isn’t the same as with a game that has gotten a touch screen makeover. Still, it will probably get a look in sooner rather than later.

Sumatran Storm Reviewer Opinion

I recently played IGT’s Sumatran Storm online slot and was thoroughly impressed. The exotic theme, featuring the majestic Sumatran tiger, along with the unique MultiWay Xtra wagering, provided an engaging experience. The free spins bonus, triggered by tiger’s eye symbols, offered decent winning opportunities. Overall, it’s an exhilarating game worth trying.

Final Verdict: A Worthwhile Adventure

Sumatran Storm is an original slot that sometimes tries to be too clever for its own good. The warm colour palette makes it feel different from its illustrious predecessor, Siberian Storm, but other than that, the two games are quite similar.

The graphics are a little better during the Sumatran Storm, but the previous version is more streamlined and mobile-friendly. A rather thematic alternative would be another classic – the White King slot by the industry giants Playtech.

IGT’s Wolf Run meanwhile is another timeless classic that has earned huge popularity in land-based casinos. And if you are wondering where to play all of these nice pieces of art, you can refer to our list of the sites with the best online slots in the UK.

Sumatran Storm is definitely worth a spin or two, even though it is competing with a lot of hit slots running a similar theme. It manages to do a lot of things right and stands apart from the competition, though some more effort in revamping the classic Siberian Storm graphics would have been nice.

All to all, if you like this sort of slots, then this is a good pick for you. It certainly looks and feels different from most of the things you have played, and offers a very strong base game with frequent payouts.
