Base Game Mechanics & Payouts
Mechanics
Grim Muerto is played on a 5×3 reel layout with 20 fixed paylines, with wins formed by matching symbols from left to right across active paylines. Before every base game spin, one reel is randomly highlighted. If the Guitar Wild lands on that highlighted reel, it expands to cover the entire reel, increasing the chance of completing winning combinations.
The game also includes a Second Chance feature. Landing two Book Scatter symbols triggers a pick-and-click bonus where you select one of four Mariachi band members. Depending on your choice, you can either receive an instant cash prize or reveal the third Scatter to activate the Free Spins feature.
With bets ranging from £0.20 to £100, Grim Muerto caters to a variety of bankrolls. Before playing for real money, it’s worth checking the minimum deposit required by your chosen UKGC-licensed casino, as this can vary between operators and payment methods.

A Closer Look at the Bonus Features for Grim Muerto
Expanding Guitar Wild
Before each base game spin, one reel is randomly highlighted. If the Guitar Wild lands on that highlighted reel, it expands to fill the entire reel, creating additional winning opportunities across the 20 paylines.
Second Chance Feature
Landing two Book Scatter symbols activates the Second Chance feature. Players choose one of four Mariachi band members, with the chance to reveal the missing third Scatter and trigger Free Spins or win an instant cash prize instead.
Free Spins
Landing three Book Scatter symbols awards the Free Spins feature. During the bonus round, between two and five reels are randomly highlighted before each spin. Any Guitar Wild landing on a highlighted reel expands to cover the full reel, and additional Extra Wilds can also appear, increasing the potential for larger wins. The feature can also be retriggered by landing three Scatters again.
From the Player’s Mouth: Real Experiences & Expert Advice
Player Sentiment: Players generally praise Grim Muerto for its colourful Day of the Dead presentation, entertaining soundtrack and engaging expanding Wild mechanic. The Second Chance feature is particularly well received because it gives players another opportunity to trigger the bonus after landing only two Scatter symbols. Some players, however, feel the game’s 2,500x maximum win is modest compared to more modern Play’n GO releases.
Expert Tips for Volatility
- Tip 1: Pay attention to the highlighted reel before every spin, as this determines where the expanding Guitar Wild can appear.
- Tip 2: The game’s biggest winning potential comes during Free Spins, where up to five highlighted reels and Extra Wilds can combine for significantly larger payouts.
- Tip 3: Don’t overlook the Second Chance feature. Triggering it with two Book Scatters gives you another opportunity to unlock the Free Spins bonus without needing a third Scatter to land naturally.
