Yo Ho Ho Matey! Welcome Aboard!
Ahoy, me hearties? Are you ready to set sail for a fantastic adventure in seven seas? I bet you are! So, immerse yourself in the treasure-laden Book of Skulls slot machine and uncover new worlds with a group of swashbucklers. Dramatic music resonant with the Pirates of the Caribbean soundtrack chimes on in the background, laying the foundation for an exhilarating experience.
Pirates: the captain, quartermaster, first mate, and second mate take up the most prominent positions in order of seniority as the medium-paying symbols. Meanwhile, the 10 to A of a royal flush poker hand take up the role of low-paying symbols in the Book of Skulls online slot. As for the specials, we only have a cursed tome, the Book of Skulls, which doubles up as the slot game’s wild and scatter symbol.
Bring a Spring Upon Er’ and Land Huge Payouts!
Spinomenal’s Book of Skulls online slot is a 5-reel, 3-row number with 10 paylines and medium variance. Additionally, it’s worth pointing out that your gameplay RTP could either be 88.94%, 91.71%, 93.96%, or 96.41%, depending on your casino of choice. Launch the title, and you’ll have the opportunity of placing your wagers between 0.1 and 100 coins to rake in wins based on the paytable below:

Plunder the Bounty!
Play Book of Skulls slot online and get to loot as much bounty as you can with the help of special features such as:
The Book of Skulls, which is both the wild and scatter symbol. As a wild, it will stand in for all other in-game characters to complete a winning combo, whereas it triggers the free spins feature as a scatter.
3 or more scatters anywhere on the reels will award you 10 free spins on top of earning you a payout based on how many of them you landed. Upon unlocking the free spins, a wheel containing all regular symbols will appear; spin it for the random selection of a special expanding wild symbol.
After completing your free spins and collecting your wins, the special expanding symbol will enlarge to form additional winning combinations. This special expanded symbol will award payouts according to its paytable value, on top of your free spins’ gains.
