Los Cuatro Esqueletos Slot by Relax Gaming 🎰 Free Demo and Review

Los Cuatro Esqueletos Review

Los Cuatro Esqueletos translates to ‘The 4 Skeletons’, in case that wasn’t clear, and the Day of the Dead Mariachi band consists of 2 male and 2 female skeletons. Thunderkick made this theme popular years ago with their instant classic, Esqueleto Explosivo, and Los Cuatro Esqueletos is a far more static game in that regard. You get some okay animations here and there, and, of course, some cheerful Mariachi music, but there is nothing really new to see here.

Relax Gaming has decided to build everything around the well-known ‘book slot’ mechanic, and nothing much happens in the base game except wild/scatter collection. This will eventually lead to a Super Bonus Round where you get 2 special expanding symbols from the upfront pick game, while the regular bonus round gives you only 1 pick. The 10,000x potential is above average for the ‘book of’ genre though, but the 94 % top-tier RTP is below average.

Los Cuatro Esqueletos Slot Features

The 4 skeleton characters serve as the premium symbols, and they pay between 75 and 500 x your stake for 5 of a kind wins. The low-value symbols pay 10 to 15 x your stake for the same, which is good to know since this is a ‘book of’ mechanic slot. The Pinata Wilds step in for non-expanding pay symbols to help complete and/or improve wins, and they serve double duty as scatters.

The Bonus Round triggers when you land 3+ Wild/Scatters in view, and this gives you 10 free spins. You retrigger the bonus round with +10 extra spins whenever you land 3+ wild/scatters on the same free spin, and the feature starts with a pinata pick game. Your pick reveals a pay symbol, and it becomes the special expanding symbol for the duration of the bonus round.

The special expanding symbol does its thing after the initial win calculation, but only if there are enough instances of it to create a win. All instances of the symbol will then expand to cover the full reel, and it does not matter if the symbols are adjacent or not. They pay from anywhere, in other words, and only 2+ symbols are necessary to create a win if the chosen symbol is a skeleton character.

All scatters that appear are collected, and you need to collect 600 scatters to trigger the Super Bonus Round. It comes with 10 super free spins, and the big difference from the regular feature is that you get to pick 2 special expanding symbols up front. You can retrigger the super bonus round as well, and the bet size will be an average of the bet sizes you used during the scatter collection phase (details about this are found in the paytable).

The bonus round triggers at 0:28 into the 2-minute highlights video, and you get to see a few scatter collections before that. We got the regular bonus round, however, and the pinata pick game revealed the low-value royal symbol ‘A’ as our special expanding symbol.

Review Summary

Well, we have seen far better Day of the Dead slots for sure, and the same can be said about ‘book slots’. Relax Gaming has picked a tough genre to compete in, although there aren’t too many slots that combine this festive theme with the ‘book of’ mechanic. That’s the biggest selling point, really, but the math model is not really doing this release any favors. We are thinking about the top-tier 94 % RTP in particular, as there are far better alternatives out there. Book of 99 comes to mind, for example, as it sports a solid 99 % RTP.

The regular bonus round has been seen countless times before, of course, but the expanding symbols animation is neatly done nonetheless. You need to stay loyal for a while to benefit from the super version of the bonus round, and it’s not really all that tempting due to the lower than average theoretical returns. Getting 2 special expanding symbols is hardly revolutionary anyway, but players looking for some Día de los Muertos ‘book slot’ action may enjoy Los Cuatro Esqueletos despite the drawbacks we’ve pointed out.
