Grim Muerto Slot from Play’n GO Reviewed and Tested
Last Updated:This Mexican-styled game brings the Day of the Dead to life as you look out for undead mariachi players on the reels. Grim Muerto was released in 2016 and provides a charming, colorful type of game where you can try to win some dinero. The gameplay is pretty standard, but it is the exciting theme and beautiful graphics that help it to stand out.
Grim Muerto Boasts a Number of Features
The screen shows a set of five reels spread over three rows, with a selection of Mexican images behind them. You can win on any one of 20 paylines, with all wins except scatters paid out from left to right. The slot is packed with many exciting features that make gameplay more interesting and rewarding. One such is the Marco Siniestro, which is one reel that is highlighted on every spin. If a wild symbol lands on it, this valuable symbol will expand and cover the full reel.
Two scatter symbols will activate the Second Chance feature. A mariachi you choose will give you a reward while the hidden scatter will activate the free spins round that comes with an extra wild symbol and up to five highlighted reels.
Día de Muertos Theme and Symbols
The Mexican Day of the Dead style has been carried out brilliantly throughout this slot, with colorful outfits and amusing mariachi players giving it an exotic feel. The musicians add some extra emoción to the proceedings by playing their different instruments as they land on the reels.
The high-paying symbols are the four mariachi playing different instruments, while the usual card symbols from 10 to Ace are the low-paying ones. A golden guitar is the wild symbol which has the highest payout, the book symbol is the scatter, and the candle symbol will re-trigger the free spins.

How to Play the Grim Muerto Slot
Set your stake first by choosing the coin size and number of coins you want to play with, which will mean that the bet size is shown under the reels. You don’t need to select how many paylines are active, so you are now ready to hit the spin button, amigos. The music adds to the Mexican fiesta feeling, but you can turn it off if you prefer to play in silence.
Three of the book symbols are needed for you to unlock ten free spins with an extra wild. If you only get a couple of scatters, you are given a second chance to get a third one on a free re-spin. As is typically the case on most slots, a wild symbol can stand in for other icons, except the scatter, to complete wins on your behalf.
The Grim Muerto Free Spins Game
The free spins round is where you can hope to get the most exciting wins on Grim Muerto as it is played with between two and five highlighted reels. When you enter into this round, one of the bony mariachi players becomes an extra wild. You can also re-trigger more gratis spins, with three candle icons. This bonus round is where you are probably going to earn your biggest wins, so it pays to make the most of it every time you play it.
Will You Try a Free Grim Muerto Slot Demo?
Try this bone-shaking slot without any risk, as you can play the demo version without using a single peso of your own cash. Just spin for free and see whether you want to play for real later on. The free Grim Muerto online casino game has all features enabled so you can get a real sense of what it offers in terms of gameplay and payouts.

What About the Payout?
A 96% RTP and a medium level of volatility mean that this is a slot most people should feel comfortable with, as wins pop up fairly regularly. The top paying symbol is the guitar wild, and it has a maximum value of 1,000x your bet. There is no progressive jackpot to be won on here, but the best symbols pay very decent win amounts. The highest paying symbol is the golden guitar wild which rewards players up to 1,000x their bet if they get five of it on a payline.

This is an amusing slot with an interesting Mexican theme that makes it more unusual to look at than many other games of this type. The features keep it rolling along smoothly and you might even find that you whoop along with the festive músico as you play.
