Follow the steps of Lara Jones, a brave explorer determined to unravel the secrets of Egyptian pharaohs. The Blue Diamond Book is a video slot created by Spearhead Studios. This game with an exciting theme has a rather dull matrix – 5 reels and 10 paylines. However, you can expect refined visual elements, including polished, shiny symbols in various colors and dark reels. Behind the matrix, you can spot a temple, crystals, and a pharaoh. Players will be listening to instrumental music with haunting vocals. The 10 paylines we've already mentioned are fixed. Symbols pay from left to right on these paylines. The Blue Diamond Book slot has free spins but also multipliers and wild icons. This is another mobile-friendly release from Spearhead Studios. If you want to try this game for free, use GoodLuckMate whenever you are ready.

How to play

One of the first things you should do on the Blue Diamond Book slot's main screen is to click on the coins. This move will let you choose the bet amount. This time, there are 18 options. The minimum amount that you can use is worth €0.10. The maximum amount, on the other hand, is €100. You can start playing by clicking on the biggest blue button. You can also activate an auto-spin mode by using the blue button above.

This 5-reel, 10-payline slot with 3 rows has other options too. You will find a speaker in the left upper corner that can help you activate or turn the music off. On the opposite side, there are three white lines. Use them to open the Settings, Paytable, and Game Rules sections.

Symbols and payouts

Five low-paying and four high-paying basic symbols are on the payout table of the Blue Diamond Book slot. The low-paying ones are represented by playing card symbols. First, we have the blue 10s and green Jacks. They provide 5, 20, or 60 times the line bet for three, four, or five 10s or Jacks on a line, respectively. The purple Queens and turquoise Kings will deliver 10, 40, or 100 times your bet per line. Last in this group is the red Ace that promises 15, 60, or 150 times the line bet for three, four, or five of them on a payline.

The high-paying basic symbols start with the scarab. It pays 10, 40, 100, or 250 times your line bet for two, three, four, or five scarabs on the same line. You will get the same prizes if you hit identical combinations of golden ankhs. Another high-paying symbol is the Eye of Horus. 15, 60, 150, or 400 times the line bet can be won if you land 2, 3, 4, or 5 of them on a single payline. Try to get the same combinations of Lara Jones icons to win 20, 100, 250, or 1,000 times your line bet. The only special symbol in this game is not a paying symbol.

Best Blue Diamond Book bonus feature

One very special symbol is the key to the Blue Diamond Book bonus features and extras. This is a blue book with a cover made of diamonds. For starters, as some of you might have guessed, this is a wild icon. So, it counts as any missing basic symbol when it can help players form winning lines. You can win up to three wild icons in a single round.

Since the wild icon acts as a scatter icon, too, a combination of three wild scatters on the reels will activate a round of Blue Diamond Book free spins. To be more precise, players can expect 10 free spins in this way. What's even better is that one of the basic symbols will be transformed into an expanding symbol during free spins.

Furthermore, all reels during free spins will have one scatter wild icon. These spins are played on a regular matrix. When you land two expanding symbols on the reels, and there's one or more scatters on the reels, they will expand too. On top of that, the scatters will reveal win multipliers – 1x, 2x, or 3x multiplier for the win in situations like this. In this way, the maximum scatter win multiplier is 27 times the prize.

RTP & Volatility

As for the Blue Diamond Book RTP, it's a decent Return to Player percentage of 96.04%. The volatility is on a high level. In theory, this means that you should expect fewer wins, but these wins will be relatively big.
