Book of Cleo

Book of Cleo is Tom Horn's entry in the book-slot genre, set inside a temple chamber where Cleopatra watches from her throne. The grid is five reels by three rows with nine paylines, and the queen herself is the highest-paying symbol, ahead of a crown, a scarab and the Eye of Ra.

Three book scatters start 10 free spins with a special expanding symbol, and a shatter mechanic replaces winning symbols while a multiplier climbs from 1x to 4x. Players who would rather skip the wait can buy the free games for 80x the total bet. High volatility, a 95.05 % RTP and stakes from 0.5 € to 100 € point to players who like swingy sessions; the top win is listed at 500x the bet.

Wins pay on nine lines. Cleo, the crown, the scarab and the Eye of Ra form the premium group, while the card ranks A, K, Q, J and 10 cover the low end and pay up to 15x the bet for five of a kind. Three-symbol wins start at 0.50x the bet, and the top symbols pay from just two on a line. The game is built in HTML5, so it runs on phones and desktops without a download.

• Free spins: three book scatters award 10 free spins, which can be retriggered. One symbol is picked as the special symbol and expands to fill its whole reel when it lands.
• Shatter mode: winning symbols break apart and new symbols drop into the gaps, raising the win multiplier step by step from 1x up to 4x.
• Buy feature: the free games can be bought outright for 80x the total bet.
