Mr Green Casino  has just added the forthcoming slot from Quickspin to their casino as an exclusive early release, the Skulls Up slot has an official release date of the 14th January 2020, but is exclusively playable today at Mr Greeen.

The Skulls Up slot is a cartoon-styled pirate-themed online slot, using the “ways” payline system and adding a few novel features to this popular payline format. The base game starts as a regular 5×3 reel 243-ways slot but the addition of special Skull and Flaming Skull wilds enables to middle 3 reels to be expanded and increase the number of winning ways up to a maximum of  1944 ways.

The Flaming Skull symbols are the real key to this slot as they act like semi-sticky wilds awarding Flaming Skull Re-Spins with expanded winning ways as parts of the slot get unlocked, further special wilds landing on the re-spins extend this feature further whilst also increasing the number of winning ways.

The regular wilds will also increase the winning ways but do not grant the re-spin, so they are more beneficial in the main bonus round, for unlocking the winning ways quickly and reveal this slots biggest winning potential.

The main bonus round is triggered by 3 regular treasure chest scatter symbols landing on the middle three reels, awarding an initial 6 free spins. All of the same functionality is at play during the bonus round with more frequent Skulls and Flaming Skulls landing on the reels and the addition of 2 extra free spins once any of the middle reels become fully unlocked.

The real key to the bonus round though is the Flaming Skull wilds which help to extend the number of free spins with the re-spin mechanic and further re-spins after this. The gameplay is simple to understand and with regular bonus feature triggers in our playtest, you can see how this slot plays in the gameplay video below.
