Books & Bulls GDN

Review

This game expands its range of similar titles, linking it with a bonus series. Now, in addition to the two rounds of free spins, players can win additional jackpots up to a significant amount in the exciting side game.

On the outside, this edition doesn’t differ much from similar games. We see the same background image, giving us a view of a medieval street, while the reels are made up of recognizable symbols we’ve seen in other similar games. A simple approach, yet the game looks decent since the graphics are pretty sharp and detailed. The slot plays out across a standard 5x3 reel setup, and players can choose between 5 and 10 win lines.

Playable on any device, this game comes with a betting range of €0.1 to €12 per spin, so there aren’t a lot of options for high-rollers. Still, higher stakes are possible when the Extra Bet feature is enabled. The slot is powered by a highly volatile math model, while the RTP is a whisker above average, clocking in at 96.11%. However, the payback value is slightly decreased to 96.02% in the GDN feature.

The paytable consists of 8 regular symbols, namely A-10 royals, which are lows, and three higher value symbols. Three or more low symbols create winning combinations, while the premiums need only two. Combinations of five low symbols are worth from 10x to 15x the bet, and highs are worth from 75x to 100x the bet. Special symbols are Wilds, substituting for any other symbols in winning combos. Moreover, they have the highest value, paying up to 250x the bet for line wins.

Slot Features

The primary symbols are Scatters, and each triggers its respective feature of free games when 3 or more matching symbols land anywhere in view during the base game. They also award an instant cash prize from 2x to 200x your bet depending on the number of triggering symbols.

Landing 3 or more of one type of symbols triggers 10 free spins, which start with a draw of a bonus symbol. When enough bonus symbols appear on the reels, they expand to cover the reels entirely and award a payout across all win lines. Retriggers are also possible, though, new bonus symbols are not drawn.

Landing 3 or more of another type of symbol triggers 10 free spins, during which all Wild symbols turn sticky and stay in place until the end of the feature. However, retriggers are not possible.

When Extra Bet is activated, the Golden Nights Bonus feature can be triggered at random on any paid spin. When triggered, three chests will appear and open successively from left to right. If all chests contain a prize, you continue the Golden Night draw. The collected points contribute to the meter, and depending on the number of collected points, you can win one of the 6 fixed jackpot prizes. Keep in mind that playing with a higher side bet increases the chances of triggering the bonus and obtaining a special reward.

Finally, players can get additional wins with the Gamble feature, which is offered after each win you score during the base game. You can opt for either a Card Gamble or a Ladder Gamble, which allow you to double your winnings.

Review Summary

All said and done, this slot is decent, with plenty of features to keep players hooked onto their screens. The two free spins features provide a plethora of entertainment, while the jackpots offer you a chance to win significant prizes on each spin. All up, for fans of the ‘book’ genre and jackpot hunters, this game can be a worthy option.
