Book of Medusa by Spinomenal takes a five-reel game into Medusa's temple, pairing Greek mythology with a book that serves two purposes. It can help complete ordinary combinations or open Free Spins, where a selected symbol can expand across whole reels. Ten fixed paylines give the base game a straightforward rhythm before the bonus changes how you read the result.
Quick take: A dual-purpose book leads into Free Spins where separated reels can combine through expanding symbols.
Theme and Gameplay
The temple setting gives the book a natural place at the center of play. Choose a wager and press Spin, then follow matching symbols from left to right across the five-by-three layout. Ordinary wins use the ten fixed lines, so matching icons need the right positions to form a paying combination.
The book is worth watching even when it does not start a feature. As a Wild, it substitutes for ordinary symbols; as a Scatter, it contributes toward Free Spins. Those roles give the same icon a purpose within a line result and a separate purpose across the board.
Slot Features
Three or more scattered books award ten Free Spins. A wheel chooses the special expanding symbol for the round, giving you a particular icon to follow as the reels stop.
The game evaluates the initial result before eligible special symbols expand to fill their reels. Expansion happens when it can produce a win. These expanded symbols can pay across nonconsecutive reels on active lines, so a gap between them does not necessarily end the opportunity as it would in an ordinary left-to-right combination.
That second evaluation is the bonus's defining change. The first stopped layout can look modest, then become more useful once the selected symbol covers its reel. Buy Feature also offers a paid route directly into the bonus.
Feature focus: During Free Spins, watch the selected symbol across the entire board: eligible expansions can connect a paying result even when the occupied reels are separated.
RTP and Win Potential
The advertised maximum win is 5,000x the bet. That ceiling gives the expanding-symbol round room for a substantial result, but choosing a special symbol or filling a reel does not award the maximum by itself. The symbols still need to produce a qualifying win.
My Thoughts On This Slot
The strongest part of Book of Medusa is the change in attention between ordinary spins and the bonus. The base game asks you to follow familiar lines from the left; Free Spins ask you to look more broadly for the selected symbol and wait for the expansion evaluation.
That makes it appealing for someone who wants a readable line game with one meaningful change of pace. The ten-spin round remains focused on the reels, though anyone seeking frequent choices may find the wheel selection and subsequent expansions fairly hands-off.
Final Take: Book of Medusa gives its familiar book feature a clear payoff: separated symbols can become a connected opportunity.
