Stranded on a Valuable Island

The development of the Skulls UP! slot machine was carried out by Quickspin, a renowned Swedish game developer known for its innovative titles featured in some of the leading online casinos.

Even the lower-paying symbols are intricately designed to align with the overall pirate theme. The symbols A, K, Q, J, and 10 resemble coins typically found in a treasure chest. Additionally, each high-paying character symbol is associated with a name, as listed in the paytable below. For instance, the parrot is named Biscuit, the monkey is named Wrench, and the three pirates are nicknamed Smelly, Biggie, and No-Beard.

The wild symbol is represented by a skull, while the scatter symbol features a chest. Overall, the attention to detail in characterizing the symbols adds depth to the pirate theme of the game.

Secure Pirate’s Wealth

The initial treasure players may uncover in the Skulls UP! slot machine happens when they land a flaming skull wild on the reels. This activates a rapid respins bonus round. The screen transitions, revealing a 3×3 reel set atop the standard reels. The paylines increase as the flaming skull transitions to the new reels, triggering a respin.

Triggering three treasure chest scatters awards players six free spins and the opportunity for more. Each wild appearing on the center three reels eliminates another symbol on the upper reels, potentially leading to 1944 active paylines by the end of the free spins. Landing three skull wilds fully unlocks the reel, granting two additional free spins.
