Dive into the mysterious history of ancient Rome — 5 reels, 10 paylines, Expanding Symbols, and payouts up to 5,000x in Book of Rome, now at 3999a.
Inspired by ancient Roman civilization, this slot is one of the most popular versions of the "Book of" series
Book of Rome Slot is essentially part of the popular "Book of" series where a magic book acts as both Wild and Scatter. This game takes you to the ancient Roman Empire — an adventure filled with the roar of the Colosseum, the valor of Roman warriors, and tales of emperors' treasures.
Book of Rome is a particularly popular game at 3999a due to its simple rules and potential for massive payouts. With just 10 paylines, a good free spin round can deliver wins up to thousands of times your total bet. The Expanding Symbol feature is the main attraction of this game.
The game's visual design clearly reflects Roman architecture — a sunset sky and the silhouette of the Colosseum in the background. Roman emperors, warriors, eagles, swords, and the special "Book of Rome" symbol are arranged on the reels. Every spin feels like an ancient historical journey.
The most important feature in Book of Rome is the "Book" symbol — it acts as both Wild and Scatter. When this single symbol lands on 3 or more reels, it triggers Free Spins and selects an Expanding Symbol that can stretch across entire reels.
The Book symbol is both Scatter and Wild. Land 3 to start Free Spins, 4 for more spins, and 5 for the maximum payout.
Before free spins, a special symbol is chosen. Whichever reel that symbol lands on, it covers the entire reel — all 3 positions become the same symbol.
If 3+ Book symbols land again during free spins, you get additional free spins. This retrigger can happen multiple times.
Understanding Book of Rome's Most Important Feature in Simple Terms
When any 3 or more Book (📖) symbols land on the reels, free spins begin. At this moment, an Expanding Symbol is randomly selected.
Whichever reel the selected symbol lands on, all three positions on that reel fill with that symbol. A full reel guarantees a win on that payline.
If the Expanding Symbol appears on 4 or 5 reels, most paylines win simultaneously. With the Emperor symbol, payouts up to 5,000x are possible.

Important Information Before Playing at 3999a
Keep these in mind for a great Book of Rome slot experience at 3999a
Due to high volatility, Book of Rome may require more spins to trigger Free Spins. Start with a budget that allows at least 50–100 spins. At BDT 10 per bet, that means BDT 500–1,000.
The Expanding Symbol is chosen randomly and you have no control over it. But if the Emperor is selected, you have the highest potential. Don't miss this announcement before each Free Spins round.
The Gamble feature offers the temptation of doubling wins, but it's an even 50/50 chance. Experienced players at 3999a generally advise against using Gamble on large wins.
Reduce bets during long losing streaks to maintain your balance. When free spins hit, there's no need to increase bets — the feature itself delivers good returns.
The real fun in Book of Rome is in the Free Spins. Don't get discouraged by small wins in regular spins — be patient. The bonus round gives you a chance to recover what you've lost.
Set daily or weekly limits in your 3999a account settings. Extended play on high volatility games can significantly impact your balance.
Book of Rome is a high volatility game. There's potential for big wins, but also for losing streaks. Always play within your means and play for fun — winnings are never guaranteed. 3999a's Responsible Gaming section for more information.

The shadows of Roman architecture in the background, golden coins glittering in the sunlight, and ancient stone textures — together they create a complete visual experience.

The game's sound design has also been given considerable attention. Regular spins play gentle Roman melodies, big wins trigger exciting music, and when free spins are triggered, a special sound effect signals that something big is about to happen.
Since 3999a is a licensed platform, KYC (Know Your Customer) procedures are followed. Identity verification may be required for large withdrawals. This is done for player security — to prevent anyone from using someone else's account to withdraw funds.

Developed by Amatic Industries, Book of Rome first gained popularity in Europe before spreading across Asia. The universal appeal of Roman history combined with the game's simple yet effective mechanics made it a quick hit.
Since this game became available in Bangladesh through 3999a, it has quickly gained popularity. Players who've played Book of Ra especially can easily adapt to Book of Rome's familiar mechanics. However, the Roman theme and the Emperor symbol's 5,000x payout give it a distinct identity from Ra.
Book of Rome is a long-term game — if free spins don't come in one session, maybe the next session will bring two retriggered rounds at once. Losing streaks create mental pressure and tend to encourage bigger bets — that's the biggest danger.
3999a recommends playing a maximum of 1–2 hours daily. Continuous extended play is unhealthy and reduces decision-making ability. Take breaks, calculate, then decide.
