Los Cuatro Esqueletos has not gone through our rig yet. When it does, the full recorded session appears here: balance curve, hit rate, best win and the longest dry streak, published next to the official RTP above. Until then this page carries Relax Gaming's own figures and a playable demo, and nothing of ours.
The RTP is 94.00%, which sits well below the roughly 96% industry average for online slots.
The maximum win is 10,000x the bet, a high ceiling that pairs with the game's high volatility.

Los Cuatro Esqueletos translates from Spanish as "The Four Skeletons," and the game dresses them for a celebration built from Mexican folk styling, a Halloween edge, and full party atmosphere. This Relax Gaming slot, a December 2023 release, hides a demanding math model under the festive surface, and the distance between those two things defines the whole experience.
Los Cuatro Esqueletos runs on a 5x3 grid. Wild symbols substitute for regular symbols to help complete winning combinations, while scatter symbols count wherever they land. Expanding symbols round out the core toolkit: when one appears, it can grow to cover additional positions.
Away from the base game, the slot carries a long list of bonus mechanics. Free spins award a set of spins that play out without further stakes, and the progressive free spins variant escalates as the round advances rather than staying static. Symbol collection gathers certain symbols toward a goal that unlocks something extra, and the pick bonus offers a choice of concealed options that reveal prizes. A jackpot completes the list, pointing to a headline prize tier above standard wins. Together they give the bonus side genuine variety.
This is where the problems start. The RTP is 94.00%, well below the roughly 96% industry average, and that shortfall is the slot's biggest weakness: statistically, a lower return rate wears a session budget down faster. High volatility sharpens the effect, since wins land less often but tend to be larger, with extended dry spells between them; the game asks for patience and bankroll headroom. A 10,000x max win puts Los Cuatro Esqueletos firmly in high-potential territory. Whether that ceiling offsets the thin return rate is the central question, and for most players the answer is no.
The presentation blends the game's three themes into one setting: Mexican folk-art flavor, Halloween spookiness played lightly, and party energy. The title's skeletons belong to celebration rather than horror, so expect a colorful, rowdy mood with a macabre wink instead of anything genuinely dark.
Los Cuatro Esqueletos has personality, a deep bench of features, and a 10,000x top prize, but the 94.00% RTP undercuts the whole package, and high volatility makes sure the shortfall is felt rather than hidden. That combination earns it a 3/10. Players who prioritize theme over return rate may still find it worth a look, and the free demo on this page offers a risk-free try.
