Thunderkick Background

Thunderkick calls itself independent and says it has been breaking rules and setting standards since 2012. Its site promises games made with innovation and a hint of magical madness. Two companies, Thunderkick AB and Thunderkick Malta Ltd, hold its licences from the Gambling Commission in Great Britain. The studio is known for a small number of distinctive games, and Esqueleto Explosivo is the clearest example.

Game Series

Esqueleto Explosivo. The original plays on a 5×3 grid with 17 lines. Its star is the Explosivo Wild, a skull with a blond quiff and pink sunglasses, and its multiplier runs from x1 to x32.
Esqueleto Explosivo 2. The sequel moves to 99 ways. It keeps every skull pay from the first game and adds a lady skull in an orange headscarf above them. The multiplier reaches x64 in the bonus, and the top prize is 5,000x.
Esqueleto Explosivo 3. The third game changes to cluster pays on a 5×5 grid. Each winning cluster leaves a wild behind, the multiplier can reach x1024 in the bonus, and the cap rises to 7,500x.

How the Slots Work

All three Esqueleto Explosivo games use the same loop. Winning skulls are removed, new ones drop into the gaps, and each drop in a sequence moves the multiplier up a step. The Explosivo Wild adds to this by clearing symbols around it. What changes between the games is the pay system, from lines to ways to clusters, and how far the multiplier can go.

The third game shows the direction most clearly. A Wild or an Explosivo Wild replaces part of every winning cluster, so one win often leads to the next. Other games with this pay system are on our cluster pays slots page.

RTP and Volatility

Esqueleto Explosivo is listed at 96% and Esqueleto Explosivo 2 at 96.13%. Esqueleto Explosivo 3 is lower, at 94.22%, and has the largest stated prize of the three at 7,500x. Our pages don’t list volatility ratings for these games yet, so we don’t quote them.
