Book of Conquistador - Game Details
I went into Book of Conquistador as a fan of the Book-of mechanic. It runs on 5x3 with 10 paylines. The Book symbol acts as Wild and Scatter. Bets range from 0.10 to 45 EUR. Trigger three Books to get 10 Free Games with a special expanding symbol. The setup feels familiar and quick, with steady base hits and that feature bringing the drama. It's classic Endorphina adventure with a clear path to the big moments.
RTP sits at 96.05% from the studio. I found the maths steady enough for long sessions, yet screens can spark once expansions land. The interface is clean, spin tempo brisk, and mobile play is smooth on iOS and Android. The Book covers both roles, so base lines tick along while you chase the feature. No clutter, just straight slot play with that familiar Book rhythm that fans expect from this style.

Core Features in Book of Conquistador
Free Spins carry the headline. Land three or more Books to get 10 spins; a symbol is randomly chosen as the special expanding one. Expansions trigger when enough of that symbol are present to form a win, and they expand vertically after regular line pays. During my runs, mid symbols as the pick felt reliable, while a top pick can spike the round. Retriggers are on, keeping the same bet and lines.
The Classic Risk Game is here for those who like a flutter after a hit. You can try to double up to ten times by beating the dealer in a simple card game. I used it sparingly to press smaller wins. Bonus Pop is offered in some places, letting you buy straight into Free Games where allowed, which suits sessions when I want action now rather than a long grind.
Book of Conquistador - Symbols and Paytable
Symbols fit the theme: explorers, chiefs, maidens, temples and masks sit alongside necklaces, rings and maps, with the Book as both Scatter and Wild. Premiums carry the bigger returns, and the chosen special symbol during Free Games can be any regular. Wild substitutes for nine regular symbols but not for the special expanding during the feature. The set keeps pays readable across the 10 lines, which helps when judging line hits and expansion value.
Top-tier pays reach x500 for five of a kind, x100 for four, x10 for three and x1 for two. The next band hits x200, x40, x4 and x0.5 for five, four, three, two respectively. Another premium pays x100, x20, x3 and x0.5. A further one goes x50, x10, x2 and x0.5. These brackets cover the character and artefact set, giving that familiar step-down ladder across the paytable. They form the core chase during the bonus when expansions line up on multiple reels.
Lows round things off with x15 for five and x4 for four, plus x0.5 for three on two tiers, and x10, x2.5 and x0.5 on three further tiers. Scatter pays from the Book land at x2 for three, x20 for four and x200 for five. During Free Games, the chosen symbol expands after line wins, paying on any line when enough symbols are present. That's where the slot can print if you catch multiple reels.

RTP, Volatility and Max Win in Book of Conquistador
I rate Book of Conquistador as low volatility per the published stats, with RTP at 96.05% and a max win of x6000. In practice, base game hits arrive often enough, so bankroll flow felt steady, while features supply the larger spikes. The buy option, when active, trims variance by pushing you straight into Free Games. Stake range runs from 0.10 to 45 EUR, covering casual sessions and larger punts without awkward step jumps.
Book of Conquistador - Game Description
The theme leans into exploration across dense jungles and golden temples. Visuals are crisp, with the Book front and centre and ambient audio that keeps the expedition vibe. It stays true to the Book-of style without fuss. I liked the pacing with 5 reels, 3 rows, 10 lines, clear wins, and quick spin cycles. On mobile the slot runs well, touch controls respond cleanly, and the UI keeps the focus on the reels and that special expanding symbol chase.
