MADICLUBDice-slot players will know Book of Secrets Extra Dice is easily one to try at Madison Casino, the licensed online casino. This is a dice-format take on the Synot original, with 10 paylines in play. The game brings a familiar book-style adventure into a dice slot format with a high-volatility profile. It combines straightforward stake selection with feature-driven play, giving players a clear route from base spins into bonus action while keeping the pace easy to follow.
Choose your stake within the EUR 0.10 to EUR 25.00 range, then start the spin and watch the 5x3 game area resolve across 10 paylines. The core rhythm is simple, making it accessible even if you are new to dice slots. From there, the focus is on line wins, Scatter involvement and feature access, with the higher-volatility setup suiting players who are comfortable with swings in return patterns.
Wins land on 10 paylines across the 5x3 layout when matching symbols form paying combinations on active lines. With high volatility, the game is built around less frequent but more pronounced payouts, and its top advertised potential reaches 6,525x your stake. The Scatter feature and Free Spins add extra routes to stronger returns beyond standard line wins.
Book of Secrets Extra Dice is built around its paying symbols and a set of bonus mechanics that drive its biggest wins. Here is how each feature works.
The Buy Feature gives you a direct paid route into the main bonus sequence instead of waiting for it to trigger naturally in the base game. This changes the balance of play immediately, letting you exchange a higher upfront cost for instant access to the feature round and its stronger payout potential.
Free Spins award a sequence of spins that do not deduct from your balance. During this bonus phase, any wins still pay normally, so it creates a chance to build returns without spending extra on each spin. It is the game’s key feature for extending play and pushing toward the title’s higher-paying moments.
The Gamble feature lets you risk a win you have just collected for the chance to increase it. If the gamble succeeds, the payout grows; if it fails, that win is lost. This adds a clear risk-and-reward decision after successful spins and can quickly change the value of a result.
Scatter symbols pay or trigger their special effect based on how many land, rather than needing to sit on a payline in sequence. That makes them valuable across the full game area. Their appearance gives you an additional route beyond regular line combinations and can open the door to the bonus side of play.
Top payout per symbol (multiplier on your line bet):
Paying symbol (by rank) | Top payout |
|---|---|
Top symbol | 500x |
2nd symbol | 200x |
3rd symbol | 200x |
4th symbol | 75x |
5th symbol | 75x |
6th symbol | 15x |
7th symbol | 15x |
8th symbol | 10x |
9th symbol | 10x |
10th symbol | 10x |
The presentation leans into a mysterious, book-themed atmosphere that suits the title well. Expect a clear 5x3 layout, readable payline action and a pace that keeps attention on the result of each spin and feature trigger. The overall look supports the game’s adventurous tone without getting in the way of the practical side of placing bets and tracking wins.
The demo version is a practical way to explore the game’s pace, volatility and feature structure without using real funds. You can test different stake levels, see how wins form across the 10 paylines and get comfortable with how the Scatter, Free Spins, Buy Feature and Gamble options shape the overall experience.
