Diablo Reels Review

Diablo Reels is a 3-reeled slot with 3 rows, which can expand up to 6 symbols high. The 5 fixed pay-lines can increase to 10 on the fully expanded grid. Its infernal theme combines with laid-back Mexican music and style of the graphics. You can spin the reels with wagers from 0.20 to 100 credits paying 100 coins per bet on all devices. The RTP is 96.30% and the hit frequency – 18.1%, which is rather low.

Diablo Reels has high volatility – 8 out of 10 and pays less frequently in larger amounts. There is a Nudging Wild and a Full Stack Respin features, which are active during the base game and free spins. The lowermost part of the reels is active in the base game. On it appear the lower paying symbols and bonus scatters. The upper part activates when you trigger the Nudging Wild mode or land a full stack of 3 wilds on any reel.

You will play the free spins on a fully expanded 6×3 grid with 6 symbols per reel and 10 pay lines – 5 for each section. You can retrigger the free games and win 10 per trigger and retrigger. The jackpot win per spin is 2,500 times your stake up to €250,000. This is possible from a full screen of diamond symbols with or without wilds on the fully expanded 6×3 grid. The 5x boost from the multiplier nudging wild makes the win reach this amount.

The Design

Diablo Reels is set in the devil’s backyard and you can see yellow flowers spread around the grid in a circle. There is a bottle, an ashtray with a cigar or glass with a drink around the reels. You can see a large decorated human skull to the left of the grid with horns and a hat. The reels are in the centre of the screen and in the base game, only its lower half is active. The uppermost half appears with faded colours when inactive.

You can land horseshoes, limes, red peppers, BARs, bells, wilds and bonus symbols with a skull. You will see the payout of the symbols upon wins displayed over the reels. The images of the symbols are plain and bright but look good. The design around the reels is superb, very precise and authentic. You will be listening to melodic and joyful Mexican music playing. The rounds are pleasant and thrilling.

Diablo Reels Gameplay

The pay symbols in the game are 8 and there is a wild, a nudging multiplier wild and a bonus scatter. The lowest value symbols are the peppers, limes and watermelons. The red pepper returns half your bet for 3 of them on a pay-line. The lime grants your bet back for 3 symbols. The watermelon is next in value and pays 1.50x bet for 3 in combinations. These you can see on the lower part of the grid.

The BAR, horseshoe and bell are the medium-value symbols, which land on the upper part of the 3×3 set. The single BAR returns 2.50 times your stake, the gold horseshoe – 5 times your bet for 3 on a pay-line from left to right. More pays the bell – 10x stake for 3 on a line.

The premium symbols are the red 7 and the big diamond, which you can see on the upper set of reels. The red 8 grants wins of 20 times your stake for 3 on a pay-line. The big diamond is the most rewarding of all symbols and pays 50 times your stake for 3 on a line.

The wild is the red symbols with the gold word on it. This symbol substitutes for all except for the nudging wild and bonus scatter. It has a payout and it is the same as the blue diamond – 50x stake for 3 wilds on a pay-line. To get a win you need 3 symbols to land on any of the 5 pay-lines from left to right

The Nudging Wild appears on the upper reel set and it is the symbol with the word ‘WILD’ and the upper arrow. It can have a multiplier of 2x and 5x – these are the Multiplier Nudging Wilds. Their multipliers add their values when taking part in the same winning combinations. There is a scatter – the decorated human skull with flowers and the word ‘BONUS’ on it. It activates the free spins and appears on the lower grid part only.

During the play, you can land only lower value and bonus symbols on the lower 3×3 reel set. On the upper 3×3 reel set can appear middle and high-value symbols. These get surrounded by fire once having hit the reels.

Diablo Reels Features / Bonuses

There are several features active in Diablo Reels and a bonus game. When you land a Nudging Wild symbol on the lower part of the reel set, you trigger the Nudging Wild feature. Then, the reel nudges upwards and activates the upper 3×3 part of the reel. The Nudging Wild starts to nudge from its position on the lower area of the grid. For that respin, both parts of the reels are active. After this respin the lower part of the grid deactivates. The Nudging Wild leaves the grid once it has nudged upwards to the topmost row. Then, the respins end as does the Nudging Wild feature.

The second extra in the game is the Full Stack Respin feature. It activates by landing a full stack of 3 wild symbols on a spin. Then, a wild stack appears on top of the same reel with the landed wild stack on the lower part of the reel. This makes the fully expanded reel filled with wild stacks only. You get one respin of the other 2 reels while the fully wild stacked reel remains such without moving.

You may have the luck to get a full stack of wilds on the same spin when triggering the Nudging Wild feature. You can also do this during an ongoing Nudging Wild. Then, the wild stack will scroll into place on the corresponding reel on the other reel set. it will remain sticky throughout the Nudging Wild feature. You will get no more extra respins for the Wild Stack. If you land a Nudging Wild symbol during a Wild Stack Respin, the full wild stack will be kept sticky while the Nudging Wild feature plays.

Getting 3 bonus symbols, which are the scatters, anywhere on the lower reel set triggers 10 Free Spins. If on the same spin when activating the free games you trigger the Wild Stack Respin or the Nudging Wild feature, these features will play first. No free spins are used during them.

The free games play with both sides of the reel set active on a fully expanded 6×3 grid with 6 rows and 3 reels. You will also benefit from 10 active pay-lines. 18 symbols will land per free spin. You can activate the Wild Stack Respin and the Nudging Wild features on any free spin. You can retrigger 10 extra free spins with 3 or more scatters on a spin.

As usual with ELK Studios slots, you have 4 Betting Strategies or Levels to choose from and apply if you wish. These are the Optimizer, Leveller, Booster and Jumper. The Optimizer adjusts the bet level automatically. This happens according to the selected percentage of your balance.

The Leveller raises the bet by 2 levels after 5 consecutive losses. If the same thing repeats, the bet increases 2 more levels. The bet resets after a win. The Booster raises the bet 1 level after a loss until it reaches 4 levels above the base bet. The bet resets after a win. The Jumper raises the bet 1 level after every win until it reaches 4 levels above the main bet. The bet resets on a losing round.

The Conclusion

Diablo Reels has a unique theme, impressive visual and sound mechanics. Thanks to nudging and stacked wilds and accumulating multipliers, the game can gives great wins. The grid is separated into 2 parts with 3×3 sections on the lower and upper section.

You will win from 5 active pay-lines on each and 10 when all parts are activated. The free spins are 10 per activation and retrigger and play on the 6×3 grid with 10 pay-lines. The max win per spin is 2,500 times your stake, which is possible during the free spins. This is a high volatility slot and is a great choice for every player!
