Book Of Lucky Jack The Lost Pearl Slot Review
The seabed here doesn’t give up its treasure quietly. Book Of Lucky Jack The Lost Pearl sinks its reels onto a murky sunken wreck, all weathered stone wrapped in purple tentacles and barnacled rope, with seaweed creeping over the corners and scallop shells tucked underneath. Bubbles and faint light shafts do the rest of the work in dim teal-green water.
This is a game that risks everything on one round, and what happens inside that round is the reason to dive: a fresh expanding symbol is drawn on every free spin, so no spin is ever dead money. Spinomenal keep the frame familiar, running a 5×3 grid with 10 fixed paylines at an RTP of 96.01%, with Book Of Lucky Jack Baba Yaga’s Tales, Lucky Jack Book Of Rebirth Egyptian Darkness and Book Of Titans for company in the stable.
The Sunken Reels and What They Pay
All symbols pay left to right from the leftmost reel, and only the highest win on each line counts. Wins are multiplied by the bet per line. Multiple qualifying line wins in a single round add together into the total for that round.
The game is set to 10 fixed lines, so there’s nothing to adjust on that front; the ‘+’ and ‘-‘ buttons change the bet per line and nothing else. Stakes are set before the spin, and all wins for the round show in the WIN field.
At the top of the paytable sits Jack himself, the man holding the light. The drop-off below him is steep. The Treasure Chest and the two women, one in a flower crown and one a purple mermaid, fill out the premium end, with royals propping up the rest. Values below are multiples of the total bet.
- Jack (man holding light): 2 pays 100x, 3 pays 1,000x, 4 pays 10,000x, 5 pays 50,000x, 6 pays 100,000x
- Treasure Chest: 2 pays 50x, 3 pays 400x, 4 pays 4,000x, 5 pays 20,000x, 6 pays 40,000x
- Woman (flower crown) and Woman (purple mermaid): 2 pays 50x, 3 pays 300x, 4 pays 1,000x, 5 pays 7,500x, 6 pays 15,000x
- A and K: 3 pays 50x, 4 pays 400x, 5 pays 1,500x, 6 pays 3,000x
- Q, J and 10: 3 pays 50x, 4 pays 250x, 5 pays 1,000x, 6 pays 2,000x
The paytable’s ceiling is that top line: six Jacks at 100,000x the bet. Nothing else comes close, and the gap between Jack and everything beneath him shapes the whole game. A five-of-a-kind Chest win at 20,000x is a strong round by any measure, while the royals top out in the low thousands.
The Wild is a glowing book with a pearl at its centre, and it does double duty. It counts as any symbol, and it also works as a scatter, which is what carries the whole bonus structure.
The Scatter Wild Book
Three or more scattered Wilds anywhere on the slot pay immediately and trigger the free spins. The scatter prizes are paid on top of any regular line wins in the same round, which makes the book one of the few symbols worth celebrating on its own.
- 3 scattered Wilds: pays 2x the bet and awards 10 free spins
- 4 scattered Wilds: pays 25x the bet and awards 10 free spins
- 5 scattered Wilds: pays 250x the bet and awards 10 free spins
- 6 scattered Wilds: pays 500x the bet and awards 10 free spins
The bet per line stays the same as the round that triggered the feature, so there’s no reconfiguration between modes. It’s a clean handover from base game to bonus.
Free Spins and the Shifting Expanding Symbol
The standard award is 10 free spins, and the round can retrigger, adding another 10 spins when the books land favourably again. The interesting part is what happens on every individual spin.
Each spin gets its own randomly assigned expanding symbol, chosen fresh from everything on the reels except the scatter Wild itself, and it applies to that spin only. After the slot result is determined, the expanding symbol stretches to form new paylines on top of the existing ones. It only stretches where the expansion actually results in a win.
Two rules make the expansions count. An expansion pays across all active lines whether or not its symbols sit on consecutive reels, and it counts as a separate result from the original spin. A single spin can therefore pay twice: once for the line result, once for the expansion.
The consequence of the per-spin redraw is that no round is ever committed to a weak symbol. One spin can draw a royal and mostly spend itself; the next can draw Jack and fill the board. Every free spin carries the same odds of the big draw, which keeps all 10 of them live.
Buying Your Way to the Pearl
There’s no need to wait for the books to align. The Buy Feature lets you purchase a free spins round outright, and clicking the button opens a window where you can set the bet the round will play at. The buy price scales with the bet you choose, and paying it triggers the free spins immediately.
It’s a straightforward purchase with no options between different round types; there’s only one feature to buy, and the price follows the stake you set in the window.
One practical note for the base game: autoplay and Turbo Mode are both on hand. Autoplay runs continuous spins at the selected bet per line, with the number of spins chosen on a configuration screen and a pause button to stop it.
Turbo Mode shortens each round to the shortest possible game time. It’s toggled by the rabbit button on desktop or through the settings menu on mobile.
Our Honest Verdict
Overall Rating: 7.1/10
This is a game that makes you wait for one round, and that round is the entire reason to come diving: 10 spins at the bottom of a sunken wreck, where any one of them can draw Jack and fill the board. The base game between bonuses pays in modest line wins and the odd scatter crumb of 2x, and two books together pay nothing at all.
The per-spin redraw is the best decision in the build. Because no round is chained to a weak symbol, every free spin carries the same shot at the big draw, and the non-consecutive paying rule means expansions connect more often than they would in a stricter game.
Everything outside that round is thin. There’s one feature to play for, the royals barely register, and the base game offers nothing to do but wait for the books. Book-slot regulars who don’t mind a long quiet dive will get their pearl; anyone who wants something happening between features will find the water cold.
