Book of Diamonds - Open the book of riches

These days the bulk of video slots available in online casino venues are hi-tech feature-stuffed games that offer intense gameplay. Such powerful games are undoubtedly good, but they are quite loaded, and the gaming session can be quite overpowering. So, sometimes you just need slots with basic gameplay that feels light and soothing. Book of Diamonds is the perfect game if you want to enjoy a light session.

You can enjoy this relaxing gaming title on a wide range of devices. The game is optimized correctly for mobile support, and you'll enjoy a seamless playing experience.

The gameplay is powered by a 5x3 gaming grid. The visuals are one of the main attractions, and they shine in crisp HD graphics. The fruits have a nice finish, shiny and glossy, making them look great.

A rewarding Free Spins round is available and is another great attraction. The Diamond book is the special symbol, which acts both as the game's Scatter and Wild. You can also choose to buy this Free Spins round by paying a premium. The Auto-Spin option is also available in the game, use it and make your gameplay comfortable.


Theme, Design & Symbols

Book of Diamonds is based around the classic fruit-based game, which was very popular during the 1950s. You'll find different juicy fruits like oranges, watermelons, plums, cherries, and lemons on the slot's standard-sized gaming grid. Along with these delicious fruits, there are some other classic symbols, which are a part of the classic fruit theme, like the liberty bells, the BAR symbols, and the lucky 7s.

The highest win you can land in the game is worth 5,000x. The shiny red diamonds are the most valuable symbols on the grid. The graphics are old-school but are designed in a clean and simple layout. The controls are also designed in an easy-to-navigate manner, and you'll get the hang of spinning the reels quickly. An upbeat, quirky soundtrack keeps playing in the background as you play, adding to the spinning experience.

Book of Diamonds - How to Play

Book of Diamonds is a hybrid game, which means that you'll enjoy both classic and modern elements during your session. When it comes to the gameplay and the way of playing, hybrid slots work like every other free video slot title. The controls are similar, and you won't face any issues if you've played a video slot before.

You start the slot by selecting the stake, the value which you want to play within a single round or spin. Any amount can be selected between €0.10 and €100 per spin. This is quite an extensive betting range, and most players will be satisfied with it.

After selecting the stake, you just need to put the reels in motion. The golden spin button is placed right below the middle reel.

Give the slot's demo a try to make sure you understand everything about the game. The free version is available here at BETO.

Mouth-watering fruity Symbols

Book of Diamonds will quickly become one of your favourite iGaming title if you are into retro-themed games or if you just love fruits.

The golden book with a big red gem is the slot's special symbol, working both as Scatters and Wilds. If you land individual combos of these books, you can win a 250x payout for a 5-of-a-kind combo. Symbols of 4 books will give you a 25x stake, and 3 books will double your bet.

Diamonds are the most lucrative symbols, which reward you with payouts up to 5,000x for the combination of five. The lucky 7s are also quite generous, giving you 750x winnings for combos of 5 similar symbols. These high-paying symbols can also give you payouts if you land combos of 2.

The fruits are the low-paying symbols on your grid.

Boosters and Bonus Features

Although the classic fruit-based theme is followed in Book of Diamonds, the game packs some interesting Bonus Features to make your gameplay spicy and interesting.

As mentioned, the special golden book is the game's unique symbol, which acts as both Scatters and Wilds. This extraordinary book will substitute for all the standard symbols on the grid and will help you trigger the free spins round.

Enjoy a set of 10 Free Spins as you trigger the bonus round by landing 3 Scatters together on the same reel. Before the Free Spins start, you are given a single reel to spin with different symbols. This spin will determine which symbol would be the Expanding symbol for a specific round.

Expanding symbols will cover whole reels as the gameplay continues, and your chances of landing good payouts will increase greatly.

If you don't want to wait for this bonus round to trigger on its own, you may choose to pay a premium to activate the bonus round immediately. Use the Bonus Buy option and pay a 100x charge which will guarantee the bonus round on the coming spin.
