Game Rules

Grim Muerto is a 5-reel video slot with 20 fixed paylines, that summons you to join hauntingly handsome members of a Mexican mariachi band for delightful Día de Muertos (Day of the Dead) celebrations.

Grim Muerto includes a wild symbol (the guitar); a scatter symbol in the main game (the book); a scatter symbol during free spins (candles). The wild symbol can substitute for any other reel symbol except the scatter symbol to help comprise winning combinations. A combination of two or more adjacent wild symbols also constitutes a win when the combination appears along an active line.

One reel is highlighted before each spin. If the wild symbol lands on the selected reel, it will duplicate to replace all other symbols on that reel.

Scatter symbols (the book) appear only on reel 1, 3, and 5. Landing three of these symbols in the main game awards a sequence of 10 free spins. Free spins can be re-triggered by landing 3 candle symbols on reels 1, 3, and 5, up to the maximum win! Landing 1 or 2 candle symbols on the reels in free spins awards 3 or 6 additional free spins respectively.

Before the free spin sequence begins, the book will reveal a random high-paying Mariachi symbol that will act as an extra wild symbol throughout the free spin feature.

During free spins, between two and five reels are highlighted. If a wild or extra wild symbol lands on any of the selected reels, it will duplicate to replace all other symbols on those reels. Both wilds cannot land on the same reel.

The Second Chance features gives you the possibility to trigger free spins when only 2 scatter symbols (the book) appear on the reels. Pick 1 of the 4 symbols on screen for your chance to enter free spins or win instant prizes!

The RTP is 96.51%.
