Book of Diamonds Slot Review
Slot Developer
Book of Diamonds was developed by Spinomenal, a game provider that stands out for blending retro slots with modern features. While the slot follows the ”Book of” format, the focus is on expanding symbols rather than progressive jackpots.
Slot Theme and Story Line
Diamonds, sevens, bells, fruits, and BARs dominate Book of Diamonds' reels, which are heavily influenced by classic land-based slot design. This casino game isn't about narrative - it's about simple gameplay and raw payouts.
Reels, Rows, Paylines
The Book of Diamonds slot is set on 5x3 reels and showcases 10 fixed paylines. Wins are paid from left to right, and all 10 paylines are always active. The hit frequency is around 24.7%.
RTP & Volatility
Book of Diamonds’ RTP is 96.14% and the volatility is medium. Book of Diamonds hits the sweet spot for South African players looking for a balance between regular hits and features.
Betting Range
The standard betting limits are R0.05 – R600 per line, although Playabets offer up to R1,000 per line. This translates to a minimum limit of R0.50 a spin, with a maximum of R6,000 at most casinos.
Max Win Potential
Max Win Potential book od diamonds
The maximum win potential is 10,000x your bet, which is very decent. When you enter Book of Diamonds, you will see a win cap. This will differ, depending what casino you are playing at. Betfred and Tic Tac Bets allow for wins up to R3,000,000. At Hollywoodbets and Betway, however, you can win up to R30,000,000.
Graphics & Sound
The visuals are sharp and nostalgic, with polished symbol animation and bright diamonds. The sound effects stick to classic slot cues. Slot soundtracks can become distracting, so I appreciate that this isn't the case here.
Pros and Cons
Pros
10,000m maximum won potential
High ZAR betting ceiling
Expanding symbols in free spins
Buy feature available
Strong mobile performance
Cons
No demo versions at SA casinos
Game Symbols and Payouts
Book of Diamonds uses a traditional high-value fruit slot paytable with modern multipliers layered in through wild behaviour.
Regular symbols
Sticking with the classic slot theme, the regular symbols are reminiscent of fruit machines. With the exception of fruit symbols, wins come from matches of 2, 3, 4, or 5 symbols landing on paylines
Symbol | Match 5 | Match 4 | Match 3 | Match 2` |
Red Gem | 5,000x | 1,000x | 100x | 10x |
7 | 2,000x | 400x | 40x | 5x |
Bell | 750x | 100x | 30x | 5x |

Special Symbols
Special Symbols book of diamonds
Book of Diamonds
The Book of Diamonds is the wild symbol and also the scatter. 3 or more Book of Diamonds symbols trigger the free spins. Wilds anywhere on the slot will multiply wins and pay as follows:
- 3 Books - 2x
- 4 Books - 25x
- 5 Books- 250x and will trigger 10 free spins
Book of Diamonds Demo Version and Free Play
Book of Diamonds doesn't have a local demo version in South African casinos right now. However, you can still test the game for free at the official Spinomenal demo library.
Playing the Book of Diamonds demo first is a good idea, especially since this slot has a lot of volatility once expanding symbols and multipliers come into play. Playing risk-free will help you predict when they will fall and how they work, so that you can adjust your bets accordingly.
Book of Diamonds Bonus and Key Features
Book of Diamonds is built around 3 features that combine to bring serious payout potential.
Free Spins
Book of Diamonds Bonus
Landing three Book of Diamonds symbols triggers 10 free spins. Once activated, a special reel spinner selects one symbol that becomes the expanding symbol for the entire bonus round.
Expanding Symbols
Expanding Symbols
During the free spins round, the symbol that was chosen to be the expanding symbol gets to shine. If it lands in a space that creates a win, it expands to cover the entire reel. You are paid out for the original line win, as well as the new wins that the expanded symbol creates.
Free spins can be retriggered and will continue with the same expanding symbol. This structure is where the biggest payouts in the game come from.
Buy Feature
Buy Feature book of diamonds
It is natural to become impatient waiting for the magic Book of Diamonds to fall onto the grid. Luckily, there is a Buy feature that lets you buy the spin that will make it happen. It is not cheap, costing between R5.20 and R5,200, depending on the bet size.
Use the Buy Feature option wisely. It is not guaranteed that you will make enough money to compensate for the price. Try using it in the Book of Diamonds demo mode to help you work out a strategy for when it might be best to use it.

Mobile Play Experience
Us South Africans love to play online slots on our cell phones. When I play on my Samsung, the symbols are clear, and the menus are very easy to read. I prefer to play in portrait mode, but if you flip your phone into landscape mode, the grid takes up the entire screen.
When you play at casinos like Hollywoodbets, you will be able to play in Data Free mode, which greatly reduces the amount of data used when playing slots and live games.
Book of Diamonds Expert Tips & Strategies for Winning
Unfortunately, I cannot give you any tips that will ensure that you hit the big wins on every spin. However, I can give you some tips on what I find is the best way to approach Book of Diamonds.
- Manage Your Bankroll: This is the most important strategy. You need to play for long enough that the Book of Diamonds symbol gives you free spins. Stick with bets that you are comfortable with and, preferably, will allow you to play at least 200 spins.
- Buy Feature: It is best that you wait a while before you even consider using the Buy Feature. I always play at least 100 spins first.
- Adjust the Bet Size: It is best to start off with bets that match the lower end of your budget. Book of Diamonds tends to start throwing out teasers before you get the free spins round. When I start to see 1 or 2 land, I start to increase my bet.
- High Roller Bets: If you are looking for the best high roller betting limits, play at Playabets. You can spin for up to R100 per line at this Book of Diamonds casino.

SportsBoom Suggests – Is Book of Diamonds Worth Playing?
If you are looking for a classic slot with a retro feel, then Book of Diamonds might be just what you need. There might not be a jackpot to play for, but I feel that the 10,000x win potential and expanding wilds make up for that.
Start with the demo mode before you move up to playing for real money, and good luck!
