Book of Captain Silver

Book of Captain Silver Slot Review

The scene inside the pirate ship takes me back to the ever fond school days where one year our class, the raucous ones in the bunch, took on the task of setting up a “ghost chamber” at the annual fundraising day. It was pitch dark in our “dungeon”, with only a glimmer of light emanating from the odd candle. We had made maze paths inside with many other eery and hideous spots along the way. The mouldy wooden planks fit right in. I was in a huge barrel with my very best friend, far from the exit, both dressed in black bin bags, no teeth, and the ugliest looking greyish, uncombed wigs I have ever seen. The music “gurgled” in the background and when our customers came along, sweaty as all hell, we jumped out the barrel and clobbered them with our broomsticks. This mystery and gratification sends an exciting memory flashing by.

So, the gritty realism of the Book of Captain Silver by All41 paints a picture that could speak a thousand words. Yours will be different to mine and unalike the next, but it’s these visions in our minds that are devoted to our beautiful pasts.

The Caribbean winds are taking us across the seas, the barrels of rum are tightly sealed, and the treasure chest takes the stage. Be sure to make memories on these seas. May they be magnificent.

Game Play

Wins line up when at least two premiums or three low pay symbols land left to right from the first reel. Lower value symbols include 10-A card royals, while compasses, pistols, ships, and Captain Silver make up the high pays. Values are at the upper end of the 'book of' spectrum, with five of a kind premium-wins triggering payouts worth 75 to 500 times the stake.

Pirates weren't exactly renowned for their bookish tendencies, yet a mighty tome is used in Book of Captain Silver as both wild and scatter symbol. As a wild, it replaces any pay symbol to complete regular line wins. As a scatter, 3, 4, or 5 in view award 10 free spins plus a payout of 2, 20, or 200 times the stake, respectively. Before free spins start, the book flips its pages to randomly select one of the high or low pay symbols. After initial rewards have been paid out on a free spin, if the chosen symbol can create a win, it expands to fill all positions on its reel. Expanded symbols pay all lines from any position – they do not have to start on reel one and do not need to be adjacent to each other. Wilds cannot be picked to be expanding symbols, nor do they substitute expanded symbols either. Moving on to the next feature, whenever a wild symbol lands, it is collected in a chest located at the bottom of the screen. Collecting wild scatters grants a chance of triggering a spin of the jackpot wheel. Once activated, a ship's wheel, divided into segments and covered in jewels, spins once. Whatever coloured jewel it lands on, a corresponding jackpot is awarded. The 4 jackpots are the Mini, Minor, Major, and Mega, worth 15x, 50x, 500x, and 10,000x the bet, respectively.


Titled Book of Captain Silver, today's offshore antics have taken one of the most popular game mechanics, chucked on a doublet, some breeches, a cutlass, and shipped off a pirate-themed 'book of' slot. The studio has also sweetened the deal by adding on 4 fixed jackpots to accompany the free spins expanding symbols feature central to these sorts of games.

Down in the bowls of Captain Silver's ship is where players find themselves when the game hits the screen. All41 has gone for gritty realism, filling the view with mouldy wooden planks, skulls, burned candles, and barrels containing mystery cargo; don’t forget the barrels of rum, and, let's pretend gold coins. It makes a change from the usual deck setting, sails full of trade winds, as a ship powers across the waves under a clear Caribbean sky. The other significant change can be seen right away at the left-hand side of the screen. Here, 4 jackpots are located displaying multiples of the total stake, while a chest rests beneath the reels to be filled when scatter symbols land. The rest of the game has been set up to the usual 'book of' specifications, meaning 5 reels, 3 rows, and 10 fixed paylines.

All41 has designed Book of Captain Silver to run on any device, allowing players to set bets from 20 p/c to £/€25 per spin. The RTP is a generous 96.40%, but lookout for a 94.24%.

Book of Captain Silver being what it is, one of the main features is its free spins bonus round where symbols are chosen to expand for potentially big wins. However, it's not the only extra, and All41 has also included several jackpots which don’t often appear on these sorts of slots.

Some may find the background imagery a bit dingy. Its realistic representation of life at sea wouldn’t exactly be a great way of recruiting swabs to the cause compared to enticing them with something warmly exotic. Yet, it gets the job done and is a bit more original. The soundtrack is inspirational, calling for a trip on an open sea. All41 Studios did an excellent job delivering players a true pirate experience.


The jackpot feature proved extremely tricky to activate, also sort of fading into the background. There is no faulting Book of Captain Silver's free spins round where full-screen captain wins are worth 5,000 times the bet if five land to expand. It's nice to know there is a secondary way of possibly winning big too, and the Mega Jackpot offers twice the rewards 'book of' slots typically come with.

Max Coin

Maximum win of x 10,000.


We raised a lot of money that day in our dungeon. I hope you have done the same today.
