Esqueleto Explosivo slot review

Esqueleto Explosivo slot at a glance

Esqueleto Explosivo comes from Thunderkick, a Stockholm studio founded in 2012 that holds Gambling Commission accounts 40165 and 41752 and has built a catalogue of roughly 110 games, none of them branded. This skeleton band (esqueleto is Spanish for skeleton) became the studio's best-known series and later got a sequel, Esqueleto Explosivo 2.

The original is a compact design: a 5x3 grid, 17 fixed lines and no bonus round to chase. That makes it unusual among modern online slots, most of which keep the big prizes locked inside a scatter-triggered feature. Here, every spin can run the full feature, because the feature is simply the chain of explosions.

How the features work: explosions, drops and the 32x multiplier

Every win in Esqueleto Explosivo triggers the same chain. The skulls that formed the line explode and vanish, the symbols above slide down into the gaps, and new skulls drop in from the top to fill the grid. If that refill creates another line, the process repeats. This is a form of cascading reels, and it means one paid spin can produce several wins in a row.

The climbing win multiplier

Each consecutive explosion raises a win multiplier, which tops out at 32x. A spin that stops after one win pays at the starting level; a spin that strings together a long sequence pays later wins at a higher multiple. The multiplier belongs to that single spin and resets when the cascade ends, so there is nothing to carry forward and no reason to think a long chain is "due". The game's help screen shows the exact ladder of steps.

The exploding wild

The wild symbol does two jobs. It substitutes in lines like an ordinary wild, and when it lands it blows up the symbols next to it. Those cleared spaces refill just as they would after a win, which gives the cascade another chance to start or continue, and every extra explosion counts towards the multiplier.

There are no free spins, no scatter symbols and no bonus game in this title. If a site describes a free spins round for the original Esqueleto Explosivo, it is mixing it up with the sequel.

A worked example of an Esqueleto Explosivo cascade

The table below shows how a chain builds. The line values are invented for illustration, and the multiplier steps are labelled as rising levels rather than exact figures, because the paytable is the place to check those. What matters is the shape: the same base win is worth more the later it arrives in the chain.

Because the prize cap is 700 times the stake, even a long chain has a ceiling: at 50p, the most a single spin can pay is £350.

Esqueleto Explosivo RTP and volatility for a £20 budget

An RTP of 96.0% means that, over a very large number of spins, the game pays back £96 for every £100 staked. The other £4, or 4% of everything you stake, is the house edge. That is a long-run average. Any single session can finish well above or well below it.

The cost depends on how much you put through the reels, not on your starting balance. The table shows the average loss for 100 spins at three stakes, using the plain formula stake × spins × 4%.

Low volatility is the useful part for a small budget. The game's prizes are spread across many modest results and capped at 700× the stake, so balances tend to drift rather than lurch. At 10p, a £20 budget has room for a long session, and returned wins put back through the reels stretch it further. At £1 a spin, 20 losing spins in a row would empty the same budget, so the stake you choose matters far more than any feature. For background, see our guide to slot volatility.

The 700× max win in context

A 700× cap is low next to many recent releases. Esqueleto Explosivo 2 raises it to 5,000× and Thunderkick's Pink Elephants 2 lists 10,000×. The trade-off is volatility: when the top prize is smaller, more of the 96.0% return has to come back through everyday wins.

• At 10p a spin, 700× is £70.
• At £1 a spin, it is £700.
• At the £5 limit for players aged 25 and over, it is £3,500.
• At the £2 limit for players aged 18 to 24, it is £1,400.

Reaching the cap needs a long, multiplied chain, and nothing tells you when one is coming. Each spin is decided by the random number generator on its own.

How to play Esqueleto Explosivo online

1. Open the game and read the paytable and help screen, including the multiplier steps and the RTP shown for that casino's version.
2. Set your stake with the coin controls; the 17 lines are fixed, so the stake covers all of them.
3. Spin once. Each spin takes at least 2.5 seconds under UK rules, and there is no autoplay.
4. Watch the cascade: wins explode, new skulls drop and the multiplier rises with each consecutive explosion.
5. When no new win forms, the total for that spin is added to your balance and the multiplier resets.
6. Check the net spend and session time display before deciding whether to carry on.

UK rules that shape Esqueleto Explosivo

Online slots in Great Britain run under design rules that have applied since 31 October 2021: no autoplay, a minimum of 2.5 seconds per spin, no turbo or slam-stop, and no celebrating a return that is lower than the stake. A cascade that pays back 20p on a 50p spin should not play winning effects. Since 17 January 2025, casinos must also show your net spend and time played in real time, and you cannot play several games at once. Our page on game design rules covers the detail.

The stake limits cap a spin at £5 for players aged 25 and over (from 9 April 2025) and £2 for those aged 18 to 24 (from 21 May 2025). The Gambling Commission's online slots stake limit guidance (opens in a new tab) explains how the limit applies across a whole game cycle, which here includes every cascade from one spin.

Esqueleto Explosivo review verdict: who it suits

It suits players who want steady, readable action at a small stake and who are happy with a modest ceiling. If you want a bonus round or a bigger top prize, the sequel or a high-volatility slot is closer to that, with more swing attached. The Esqueleto Explosivo review on gambling.com (opens in a new tab) gives another description of the mechanic.
