Meet the new marvellous slot from Play’N Go – Grim Muerto, released in July 2016. Despite the depressing name, this is an extremely cheerful and entertaining colourful slot based on Día de Muertos – Day of the Dead celebration coming from Mexican culture and widely celebrated in the Americas. The feast usually involves commemoration of the dead and lots of music by the traditional mariachi band. In this review, we will have a closer look at the games’ features, design and gameplay and see which online casino already offer it to players and give a generous casino bonus on top.

Grim Muerto slot features

Grim Muerto slot is set on 3 rows, 5 reels with 20 fixed paylines. The game symbols apart from intricately decorated typical A, K, Q, J, and 10 are all representing everything related to a traditional Mexican Mariachi band – this time consisting of cheerful animated skeletons. The four higher-paying symbols are the accordionist Amador, the trumpeter Tauro, Vincente on the Vihuela and Fernando the fiddler all clad in different coloured sombreros. Out of them all the orange Vincente is the most profitable and will award you 700 coins if you score 5 of them in one row.

There are also a few special symbols that improve your gaming experience.

The Guitar Wild symbol replaces all the other symbols in Grim Muerto slot and plays a joyful song as well. When a wild guitar symbol pops-up on a highlighted by El Marco Siniestro golden skull symbol reel, it expands and covers all the positions.

The Libro Scattertriggers the Second Chance feature – four of the band members appear on the reels with one of them being highlighted to grant you either free spins round, a cash prize or nothing if you hit the X.

Grim Muerto Slot Free Spins

If you manage to get 3 of the El Libro de Los Muertos, which means Book of the Dead symbols, on the reels, it will trigger the 10 free spins round. It is possible to go beyond the 10 free spins by landing one or two Candle scatters, in this case, you will receive 3 or 6 additional free spins respectively. The free spins in Grim Muerto, as we noticed, is the shortest way to get significant winnings.

Where to play Grim Muerto slot

Grim Muerto slot graphics and sounds

The Day of the Dead theme is not new on the slot market, but we can assure you that Play’n Go has done an exceptionally good job out of this not the most cheerful event. The graphics are superb with bright colours, and traditionally patterned backdrop creates a suitable Mexican atmosphere. Even if you’re not a big fan of skulls and skeletons, no worries, in this slot they look very friendly and cute.

Visual effects are stunning with trumpets announcing any wins, red roses flying around and neon sugar-skulls hanging on the sides of the screen.

The game reminds us a bit of NetEnt’s Spinata Granda, just slightly more deadly and creepy. And let’s not forget the music – who doesn’t love a bit of jolly traditional Mariachi action?

Grim Muerto slot – our conclusion

To say that we are impressed is an understatement – this is one of coolest slot releases of Play’N Go. Excellent design, graphics, special effects and soundtrack together with the nice bonus features and smooth gameplay on any device create a perfect canvas for some decent winnings, especially if you’re lucky during the free spins round.

How to Play It

Grim Muerto is played at five reels and twenty fixed paylines, meaning that all you need to do before you start spinning the reels is select between 11 coin values, ranging from $0.01 to $1, and stake 1-5 coins per line or up to 100 in total.

Bet Max and Auto Play are supported, whereas you can click on Paytable or Game Help to learn more about payouts and extra features.

When it comes to high-value symbols, these award wins for two of a kind and upwards, whereas three matching low-value icons are required for an instant credit payout. Guitar is Wild and it also awards payouts for two or more, while also substituting for other game icons apart from Scatter.

Special Features

Marco Siniestro is a feature with a strange name that could come in handy. Namely, it is active on each spin and it randomly highlights one reel per spin. If a Wild icon appears on the highlighted reel, it expands to cover all three positions before wins are awarded.

Book Scatters only appear on reels I, III and V, and if you get three of these, 10 free games are activated. If you receive 1, 2 or 3 Candle icons during the feature, 3, 6 and 10 free spins are added to the count. One Skeleton Mariachi symbol becomes Extra Wild during free spins, substituting for all non-feature icons.

Last but not least, we have Second Chance, arguably one of the best features we have seen so far. The feature is activated each time two Scatters appear on the reels, revealing four Skeleton Mariachi icons. You get to select one of them. If you reveal a Scatter icon, the Free Spins round is triggered, another two symbols hide a cash prize, whereas no wins are paid if X is revealed.

Maximum Payout

Grim Muerto appears to be a low volatility slot game due to the fact that base line payouts are frequent yet not too impressive, but that is not to say that you cannot win big while playing it. The Second Chance extra feature makes all the difference as it ensures the main bonus round is activated on relatively frequent basis, while also awarding instant credit payouts.


Extra Wilds and additional free spins should come in handy as well, meaning your chances of turning a profit in the final count are not bad at all.

The maximum theoretical payout that can be secured while playing Grim Muerto is 5,000 credits per line or 100,000 coins per spin, awarded when five Wild icons are found on a payline on a five-coin bet per line.


Grimm Morton Illinois

Play’n GO can be proud of how their attempt to pay homage to one of Mexico’s most famous holidays has turned out, and we have no major objections to the 2016 release.

The storyline, visual appearance and sound effects are all quite impressive, main game wins are not too bad and while the game’s extra features do not seem too attractive, they actually add serious value to all your wagers. And with total bet ranging from $0.20 to $100, there is not much more we can ask for.
