Book of Skulls – Uncharted Treasure Review

Book of Skulls – Uncharted Treasure is a pirate-treasure book slot from Spinomenal on a classic 5×3 grid with 10 fixed lines. Skulls and buried treasure set a pirate mood.

10 fixed lines

Line bets run from 0.01 to 7. The top symbol pays 10×, 100×, 1,000× and 5,000× the line bet for two to five of a kind.

The scatter book pays up to 250× the bet on its own.

Book of Skulls – Uncharted Treasure Features

The book

The book substitutes for every symbol and pays as a scatter anywhere: 2×, 25× or 250× the bet for three, four or five. Three or more start 10 free spins, and more books during the round add spins.

Wheel and expanding symbol

When free spins start, a wheel picks one symbol to expand for the whole round. After each spin it expands to cover its reels whenever that creates a win, and pays on all lines even when its reels aren't adjacent.

RTP, maximum win and buy

The demo is set to 95% RTP, caps wins at 5,000× the bet and lists a free spins buy at 104× the bet. Compare Book of Medusa, which uses the same wheel.
