Book of Medusa Review
Book of Medusa follows the classic five-reel book layout but adds a small ceremony to its bonus: before free spins begin, a stone wheel turns to decide which symbol will expand for the whole round. Medusa herself is the scatter-wild that opens the way.
The classic 5×3 book layout
Five reels, three rows and ten fixed lines make this the most traditional of the Spinomenal book games in this catalogue. Greek heroes and treasures take the higher positions on the paytable, with card ranks below them.
If you know other book slots, the base game needs no explanation; the interest is in how the expanding symbol is chosen.
Book of Medusa Features
Medusa as scatter and wild
The Medusa symbol substitutes for every other symbol and pays as a scatter in any position: 2× the bet for three, 25× for four and 250× for five. Three or more trigger 10 free spins, and further scatters during the round add 10 more.
The wheel that picks the expanding symbol
When free spins start, a wheel showing every regular symbol spins once. The symbol it stops on becomes the expanding symbol for the entire round, unlike Spinomenal's six-reel book games, which pick a new one each spin.
After each free spin, the chosen symbol expands to fill its reels only if that creates a win. It then pays on all ten lines, even when the reels it occupies are not next to each other.
RTP, volatility and the buy option
Catalogues list a 96.14% RTP and high volatility; the RTP has not been verified for the embedded demo. Published maximum-win figures disagree with each other, so none is shown here.
A Buy Feature priced at 104× the bet is listed for jurisdictions that allow it. Compare the round with Book of Lucky Jack – Baba Yaga's Tales to see the difference between one fixed symbol and a new symbol every spin.
