For entertainment only. Wins are virtual credits and cannot be cashed out.
Grim Muerto is Play'n GO's low-volatility Day of the Dead slot, following a skeletal mariachi band through a colourful Mexican fiesta on 5 reels, 3 rows and 20 paylines. A vihuela guitar plays the wild, and the free spins bring expanding wilds on marked reels.
Game mechanics
All 20 paylines are fixed on the 5x3 grid, and the vihuela guitar is the wild, substituting for regular symbols to complete wins.
Three or more scatters trigger 10 free spins, which can be re-triggered. If only 2 scatters land, the Second Chance feature gives another shot at the bonus, and once the bonus is running, wilds on marked reels expand under El Marco Siniestro.
Wins can be taken into an optional gamble (double-up) game. The maximum multiplier is 2,500x.
Features
- Guitar Wilds. The vihuela (Mexican guitar) acts as the wild, standing in for regular symbols to help complete payline wins.
- Free Spins. Land 3 or more scatter symbols to trigger 10 free spins, which can be re-triggered during the feature.
- El Marco Siniestro Expanding Wilds. During the bonus, wilds landing on marked reels expand to cover the whole reel.
- Second Chance. Hit only 2 scatters and the game offers a second chance to land the third and unlock the free spins.
- Gamble Game. An optional double-up game lets you stake a win for the chance to double it.
Why Grim Muerto has five RTP settings
Play'n GO's own game data for Grim Muerto lists five RTP versions: 84.64%, 87.52%, 91.52%, 94.57% and 96.51%. Each version keeps the name and artwork, with the maths tuned to a different long-run return. The casino picks which one it runs, within any minimum its regulator sets. Studios say they offer several because markets differ: minimums vary between regulators, and casinos weigh taxes, margins and commercial terms. A higher setting does not guarantee a profit, and a short session can finish up or down either way. This demo uses virtual credits: nothing is deposited, withdrawn or paid out, so the setting has no financial effect.

How to play the free demo
- Look for the vihuela guitar in the Grim Muerto demo: it is the wild that fills gaps in wins along the 20 fixed paylines.
- Three or more scatters start the 10 free spins, and a spin with exactly 2 scatters brings the Second Chance feature.
- During the free spins, keep an eye on the marked reels, where any wild that lands expands under El Marco Siniestro.
- After a win, either take the optional double-up gamble or simply spin on.
Why try the Grim Muerto demo
A spin that lands only 2 scatters is worth watching here, because the Second Chance feature gives it another try at the third. Inside the bonus, keep track of the El Marco Siniestro wilds as they expand on the marked reels.
