Books and Bulls is based upon the world of bullfighting and it invites players to become a torero as they chase after the next big win. The slot begins with some atmospheric music that helps to set the scene, while the action takes place on an old cobbled street, fully immersing players in the atmosphere.
The theme extends to the slot’s high value and bonus symbols. There are three high value symbols, a flamenco dancer, the torero’s cape and sword, and a pair of castanets. The lower value symbols are the royals 10, J, Q, K and A. The wild symbol is the torero himself and there are two scatter symbols, a book and a bull.
The slot offers a number of bonus features that will help players increase their winnings. The wild symbol is the most basic bonus. It will substitute for all of the other symbols, except for the scatter and bonus symbols, to help and form more winning combinations.
There are two free spin bonuses. The first is triggered by landing at least three book scatter symbols on the reels. Players are awarded 10 free spins and at the start of the spins, a symbol is chosen at random to become the bonus symbol. Any symbol except for the book scatter can be picked. During the free spins, when enough bonus symbols land on the reels, they will then expand to fill the entire reel. They will then award a payout as long as enough of them are along a payline, even if the symbols are not adjacent to one another. Best of all, the free spins can be retriggered.
The second free spins game is triggered by landing at least three bull scatter symbols on the reels. Players are awarded 10 free spins during which the torero wild symbols become sticky. This means that after landing, they will remain in place on the reels until the end of the feature.
The slot also offers two gamble features that players can use to try to increase their winnings. In the card gamble, players need to guess the colour of the next card to be drawn from the pack. If players guess correctly then the payout is doubled. In the ladder gamble, players need to try to ascend a ladder offering larger and larger payouts.
Books and Bulls is a high volatility slot and it has an RTP of 96.11%, which is in line with the average for online slots. A high volatility slot will payout large amounts but not very frequently, which means that players can expect to have to play several spins in order to start winning, but of course, there is no way to accurately predict when a winning spin will occur.
The slot has a top payout of 2500x that is won by landing five torero wild symbols along a payline. The flamenco dancer can payout up to 1000x, the cape and sword up to 750x, and the castanets up to 750x. A and K can both payout up to 150x while the remaining royal symbols can payout up to 100x. Both scatters can payout up to 200 times the bet when the slot is played with 10 paylines and up to 100 times the bet when the slot is played with 5 paylines.
How to Play
Books and Bulls is a very simple slot to play. Before spinning the reels, all players need to do is set how many paylines they want active, 5 or 10, and their line bet, which changes the total bet per spin, using the controls underneath the reels. All that players then need to do is click on the spin button. There is also auto play functionality that will keep the reels spinning infinitely and there is a ‘Max Bet’ button to quickly bet the maximum.
