Special Features

The 5 reels of Grim Muerto offer a colourful selection of symbols. Firstly, there are the higher value symbols of the great skeleton musicians. These adorn a range of colours; your highest value icon is the orange Mariachi, followed by purple, green and pink. Check out the animations as they form a win. Joining the Mariachis are typical playing card symbols Ace, King, Queen, Jack and 10.

You will notice a guitar symbol which is the wild and substitutes all other symbols but the scatter. The scatter symbol is the skull book. Grim Muerto also offers an extra wild within some of the bonus features.

Bonus Features

Grim Muerto

  • Marco Siniestro – one of the highlights of Grim Muerto is that there is a bonus during every spin, even in the base game. A randomly selected reel will be highlighted for that spin.  Should a wild land on the selected reel, it will expand and fill the whole reel. Furthermore, there will always be between 2 and 5 reels selected during free spins, and both wilds and extra wilds will expand (more on extra wilds shortly).
  • Free Spins – landing 2 skull book scatter symbols will trigger the 10 free spins bonus round. Your free spins will be retriggered if you land 3 candle symbols.  It is during the free spins that you are also presented with an extra wild (it will be one of the Mariachis). The extra wild substitutes all other symbols but the scatter.
  • Second Chance – the second chance feature occurs if you land 2 scatter symbols. Click a mariachi to reveal your award; revealing another scatter symbol triggers free spins. There are also cash prizes available.


We have only positive things to report on Grim Muerto. A thoroughly entertaining game with a great theme, each bonus feature seems to be really advantageous too. The highlighted reels feature is superb and makes this feel like one big bonus game. Secondly, the free spins feature occurs really frequently in our experience, probably due to the Second Chance opportunity. This is definitely one to try.
