Book of Captain Silver Slot, Details & Wager Limits

The set up in the Book of Captain Silver slot is very straightforward. The action plays out on 5 reels, 3 rows and 10 paylines. To create a winning combination, you’ll need to land 2, 3, 4 or 5 matching symbols or wilds from left to right across 1 of those 10 paylines, starting from reel 1.

To adjust your stake, click on the coins icon. You can then choose from a selection of suggested bet sizes or scroll up and down a longer list. Bet sizes range from 10p to £25 per spin. Click on the settings button (the 9 dots) to access the paytable. Payout amounts are shown as cash in relation to your current bet size. It’s all very clear and easy to follow.

The Book of Captain Silver RTP is 96.4% which is an above average figure. The hit frequency rate is 30.71%. On average, you can expect to land a winner on just under a third of spins.

This pirate pillage is a volatile one. The volatility comes in the very high range. The maximum win from a single spin comes in at 10,000 x your total stake.

Theme – Audio and Design features – set sail on a pirate adventure


With a pirate theme, the Book of Captain Silver slot comes with plenty of familiar pirate-themed imagery. The setting is below deck on a pirate ship. he soundtrack bounces along and fits the theme rather nicely. The design here is very familiar but nicely done all the same.

Flanked by barrels and candles, the reels are framed within panels of wood. Joining the lower value A to 10 symbols are a compass, musket and pirate ship flying a massive Jolly Roger. Captain Silver is the most rewarding symbol, paying 500 x your total stake if you manage to land a 5-of-a-kind combination.

The book symbol serves a dual role. It’s a wild that substitutes for all the standard symbols when it makes up part of a winning combination. It’s also the scatter. Landing 3 or more of them on the same spin trigger the Free Spins feature which I’ll look at below.

Book of Captain Silver is available to play on all devices including desktops, tablets and mobiles. Produced with HTML5 technology, the simple 5×3 reel layout is suited on smaller screens.

Book of Captain Silver Bonus Features

The theme in Book of Captain Silver is a very familiar one and the same is true of the gameplay. There are a couple of bonus features on offer including free spins with expanding symbols and a special bonus wheel that can award big jackpot prizes.

Free Spins feature


The Free Spins feature is triggered by landing 3, 4 or 5 book scatters anywhere on the reels on the same spin. After a payout equal to 2, 20 or 200 x your total stake, you’ll go on to play 10 free spins.

Before the round starts, 1 standard symbol is picked at random to become the special expanding symbol. Whenever it lands during the free spins, it expands to fill the whole of that reel, or better still, reels. Expansion wins pay on top of any standard wins achieved during the free spins round.

Getting Captain Silver is the best scenario as a screen full of that symbol will result in a 5,000 x stake payout. Retriggers are possible here too. Landing 3 or more book scatters adds another round of 10 free spins to your total. There’s no limit to how many free spins you can play with.

Captain’s Wheel Bonus feature


Any spin that includes a book scatter could randomly trigger the Captain’s Wheel Bonus feature. As its name suggests, you’ll then go on to spin a ship’s wheel that is made up of a variety of different gemstone symbols. Each gem relates to a specific jackpot prize.

The skull pointer will land on a gemstone. You’ll then win the associated jackpot prize:

Mini Jackpot 15 x stake
Minor Jackpot 50 x stake
Major Jackpot 500 x stake
Mega Jackpot 10,000 x stake

If you land both the Captain’s Wheel Bonus and the Free Spins features on the same spin, you’ll spin the bonus wheel first before going on to complete the Free Spins feature.

Book of Captain Silver Review Summary – classic ‘Book of’ slot with jackpot element

There’s nothing spectacularly original in the Book of Captain Silver slot in terms of design or gameplay. The visuals have a familiar feel and the free spins feature with expanding symbol is a common bonus round.

Whilst expanding symbols in the free spins can be found in countless other games like Book of Ra Deluxe (Novomatic), not many have a jackpot element. The Captain’s Wheel Bonus feature is the added extra which can dish out 10,000 x stake payouts.

In the free spins, a screen full of compasses, muskets, pirate ships and Captain Silver will pay 750, 750, 2,000 and 5,000 x stake respectively. These pirate waters are choppy though as the volatility is extremely high.

Will you want to set sail with Captain Silver? If you like the pirate theme, it’s worth a look. Alternatively, you have Booty Bay from Push Gaming and 123 Boom by 4ThePlayer which are better slots in my opinion.
