What Esqueleto Explosivo is
Esqueleto Explosivo is Thunderkick’s original low-volatility skeleton slot, using 17 paylines, dropping symbols and an escalating Mucho Multiplier rather than the cluster system used by later sequels.

Seventeen paylines — not cluster pays
The original Esqueleto Explosivo is a 17-payline game. That is an important correction because later games in the series use connecting ways or clusters and are often confused with the 2015 original. Here, ordinary wins are evaluated against the fixed payline structure. The visual presentation uses 15 individual reel positions across five reels, but the payment rule remains the documented 17 lines.
Dropping symbols
When a payline win occurs, the winning symbols explode and new symbols drop into the emptied positions. The board is then evaluated again as part of the same purchased round. This can create a chain of consecutive wins without another stake. The cascade sequence ends when the new arrangement does not form another qualifying win. A long chain is possible but is not owed after several single-step rounds.
Mucho Multiplier
Explosions can increase the Mucho Multiplier during a dropping-symbol sequence. The multiplier is valuable only when another win lands while the increased level applies. This is a common slot design lesson: a multiplier is a modifier of a payout, not a payout itself. A sequence that builds the meter but then stops before another qualifying combination can feel like a near miss, but it does not create deferred value for a future independent spin.
Explosivo Wild and no bonus game
The original uses an Explosivo Wild inside the dropping-symbol system, but Thunderkick’s own game information explicitly lists no separate Bonus Game. That distinguishes it sharply from Esqueleto Explosivo 2 and 3, which add Free Spins and different win systems. Any review that describes a Free Spins trigger or cluster-pay bonus for the original is mixing editions.
Where it sits in Thunderkick's catalogue
A useful internal comparison is Pink Elephants. Comparing titles from the same studio makes it clear that a provider name is not a single maths profile. Thunderkick can use fixed paylines, ways, cascades, occurrence systems, persistent feature states and radically different maximum-win caps across its catalogue.
