Game Design and Theme

The Grim Muerto online slot revolves around the festival called Day of the Dead. In it, you will be spinning symbols of dressed-up skeletons or mariachis, along with cultural symbols of Mexico like the guitar. The slot machine is in vibrant 3D graphics, and it has a lively Mexican music while you are spinning the reels. Explosions of fireworks can be heard every time you make a winning combination.


Symbols and Features

The mobile slot version in the UK has wilds, scatters, bonus rounds, and free spins. Watch out for the special symbols that trigger different features, as they can give you better odds at winning.

Wild. The wild symbol is the golden guitar. It takes the place of all other symbols to make a winning combination except the scatter. The wild also pays put coins, and the number of coins that you would receive depends on the wilds that appeared on a payline.

  • 5 – 1,000x credits
  • 4 – 250x credits
  • 3 – 50x credits
  • 2 – 5x credits

Scatter. The scatter symbol is the book with the skull emblem. Landing three of this anywhere on the grid will start the round of free games, and you will receive ten free play spins. The scatter symbol pays out 10x your total bet if you landed three of it.

Candles. A mysterious purple skull candle that only appears in the free play mode. Landing one or two will give you three or six more free spins.

Extra Wild.  At the free games round, one of the four mariachi symbols will become a Wild and will function as the normal one.

Second Chance. If you only landed two scatter symbols instead of three, you will be given a second chance. You have to choose a mariachi symbol, and this will reveal a free spin game.

Marco Siniestro. This feature highlights an entire reel. If a wild appears in that highlighted reel, the whole reel will expand into a wild. During the free spins, two to five reels will be randomly highlighted.

Symbol Wins 5 of them 4 of them 3 of them 2 of them
Wild 1000 250 50 5
Red Mariachi 700 200 40 4
Blue Mariachi 500 150 30 3

Buttons to Use

There are only a few buttons that you need to click to make the slot game work. Below is your guide if you are playing it in the UK.

  • Coin Value – this is how you set the actual currency value of your coin. Choose between 0.01 and 1 per coin.
  • Coins – you can bet up to five coins per line.
  • Max Bet – if you click this, the online slot will bet the highest amount, which is 100 credits per spin.
  • Auto-play – if you press this, you can choose how many times the reels will spin on its own. You can also set parameters for max win or losses to make the game stop spinning.

How to Play Grim Muerto Slot Machine

Operating this game is simple. And in this Grim Muerto slot review, we will have a short tutorial. First, determine who much the coin value should be. An excellent slot strategy is to choose the lowest value so you can maximise your bankroll. Next, decide how many coins you want to wager per line.

Once this is done, just click on the green Spin button at the bottom right, and the free Grim Muerto slot machine will spin. You will win money if you land three same symbols on any of the 20 pay lines. The symbols must be on adjacent reels, starting from the first reel.

The payout table does not change even if you increase and decreases your bet. This applies even if you play for free. All pays are expressed in coins, and they will be multiplied to your coin value and number of coins wagered per line.
