    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Esqueleto Explosivo belongs to a generation of machines where one well-executed idea was enough to make a game memorable. The idea fits in a sentence: the longer the drop sequence runs, the higher the multiplier climbs, and the Explosivo Wild exists to keep that sequence alive. No free spins, no side counters, no buy button.

    That restraint has a direct consequence for the profile. Thunderkick rates the title low volatility and the ceiling does not go past 700 times the stake. That is modest by current standards and worth knowing before you start. In exchange, the game delivers a regularity few contemporary machines offer, along with an audio identity that became a reference point for the sector.

    The title went on to found an entire series at Thunderkick, which is evidence enough that the formula worked. For BetsRank, Esqueleto Explosivo remains a good choice for a long session on a contained budget. Players looking for wider swings will find them in the 2020 sequel.

    Esqueleto Explosivo in detail

    Esqueleto Explosivo is a Thunderkick slot published on 26 October 2015. Do not confuse it with its sequel, Esqueleto Explosivo 2, released in 2020: these are two separate games with different grid structures, different return rates and different win ceilings. This page covers the original 2015 title and nothing else. If the numbers on your screen do not match the ones below, you are almost certainly looking at the sequel.

    The artwork draws on the Mexican Day of the Dead. The symbols are singing mariachi skulls, each with its own voice, and together they form a choir that recomposes itself with every win. That audio identity, as much as the mechanic, is what made the game's reputation.

    The grid runs 5 reels and 3 rows with 17 fixed paylines. Stakes range from €0.10 to €100 a spin. The RTP quoted by Thunderkick is 96.0% and the win ceiling, which the studio calls maximum exposure, is set at 700 times the stake. Thunderkick rates the title low volatility, which is unusual for the studio and one of the most notable things about the game.

    The reels do not spin. Esqueleto Explosivo uses falling symbols: the skulls drop into the grid, winning combinations are paid and removed, and new symbols come down to fill the gaps. As long as the new arrangement produces a win, the sequence continues and the paid spin is not over. A single spin can therefore chain several payouts with no additional stake.

    That sequence is what feeds the Mucho Multiplier, the game's signature. With each consecutive winning drop, the multiplier applied to wins moves one step up a fixed ladder: x1, then x2, x4, x8, x16 and finally x32. The counter resets the moment a drop produces no win at all. All of the game's value is therefore built on the length of a sequence rather than on any single lucky draw.

    The second element is the Explosivo Wild, a green skull that appears at random. It substitutes for the paying symbols and, more importantly, it destroys the symbols adjacent to it, freeing positions and triggering a fresh drop. It also advances the Mucho Multiplier by one step, exactly as a regular win does, which lets it extend a sequence that was about to stall.

    Esqueleto Explosivo has no free spins phase and no bonus buy. Everything happens in the base game, which is what explains both the 700x ceiling and the low volatility rating. There is no scatter to chase and no counter filling up in the corner of the screen: the only thing that matters on any given spin is whether the drop pays and keeps the ladder alive. The game is HTML5 and runs on desktop and mobile alike with no separate build.

    Esqueleto Explosivo FAQ

    What is the RTP of Esqueleto Explosivo?

    Thunderkick quotes a return to player of 96.

    0% for the original 2015 title, and that is the figure published on the studio's own game sheet. Do not confuse it with Esqueleto Explosivo 2, released in 2020, whose quoted RTP is 96. 13% for an entirely different game structure built on a different maths model.

    What is the maximum win on Esqueleto Explosivo?

    Thunderkick sets maximum exposure at 700 times the stake.

    That is a low ceiling, but it is consistent with a game rated low volatility and carrying no bonus phase at all. The 2020 sequel goes up to 5,000 times the stake, which gives you the measure of the gap between the two titles.

    How does the Mucho Multiplier work?

    With each consecutive winning drop, the multiplier applied to wins advances one step along a fixed ladder: x1, x2, x4, x8, x16 and then x32.

    The counter returns to its starting point as soon as a drop forms no combination. The entire value of the game therefore rests on how long a sequence runs.

    What is the Explosivo Wild?

    It is a green skull that appears at random on the grid.

    It substitutes for the paying symbols like a conventional wild, but it also destroys the symbols surrounding it. That destruction frees positions, triggers a fresh drop and advances the Mucho Multiplier by one extra step, which is what makes it so useful mid-sequence.

    Does Esqueleto Explosivo have free spins?

    No.

    The original 2015 title has no free spins phase whatsoever. Everything is played out in the base game, around the successive drops and the climbing Mucho Multiplier. This is the most visible difference from Esqueleto Explosivo 2, which introduced a genuine bonus phase when it arrived in 2020.

    Is there a bonus buy on this game?

    No, and for a simple reason: there is no bonus to buy.

    The game carries no scatter-triggered feature, so a buy option would have nothing to sell you on this structure. The rhythm of the title rests entirely on chaining drops in the base game, spin after spin, with no shortcut available.

    How volatile is Esqueleto Explosivo?

    Thunderkick rates the title low volatility, which is uncommon in its catalogue.

    Wins are therefore more regular but smaller in scale, and the 700x ceiling keeps the swings contained. That profile suits long sessions on a modest budget with a stable unit stake rather than a hunt for one big result.

    What is the difference with Esqueleto Explosivo 2?

    They are two separate games.

    The 2015 original offers 17 fixed lines, a 96% RTP, a 700x ceiling, low volatility and no free spins at all. The 2020 sequel offers 99 ways to win, a 96. 13% RTP, a 5,000x ceiling, a free spins phase and a multiplier ladder that climbs a step higher.

    Which of the two titles should you choose?

    It depends on the profile you want.

    The original suits a player after regular sessions, a simple mechanic and a controlled budget. The sequel shifts value into a bonus phase and widens the swings considerably. The two share a visual universe but behave very differently once you are actually playing them.

    What stake should you use on Esqueleto Explosivo?

    The range runs from €0.

    10 to €100 a spin depending on the operator. Because the 17 lines are fixed, only the bet level is adjustable. The low volatility rating allows a slightly more comfortable unit stake than high-variance titles do, while still leaving enough spins in a given budget to see sequences develop.

    Does the game work on mobile?

    Yes.

    Esqueleto Explosivo is built in HTML5 and loads directly in the browser, with no dedicated app and no separate mobile version. The 5x3 grid stays perfectly readable on a phone screen, and the drop animations and the mariachi skull voices are identical across every device.

    Is there a free demo of Esqueleto Explosivo?

    Most casinos carrying the Thunderkick catalogue offer a play-money demo mode, available without a deposit.

    It is the simplest way to see how often long drop sequences actually occur and to understand how the Mucho Multiplier behaves before you play the game for real money.
