John Hunter and Galileo’s Secrets: Slot Overview

Much like the legendary adventurer he seems to mirror, Pragmatic Play’s globe-trotting John Hunter is rarely in one place for long. In fairness, he’d been a little under the radar lately, last turning up in the 2022 release John Hunter And The Mayan Gods, but it seems the lure of discovery proved impossible to ignore. Consequently, Prag’s hat-wearing hero returns as the star of John Hunter and Galileo’s Secrets, a slot that tips its hat to earlier styles while adding a couple of fresh angles along the way.

At first glance, John Hunter and Galileo’s Secrets gave off “dusty relic” vibes. The reels looked dated and the symbols felt old-fashioned, which didn’t exactly spark instant excitement. Still, appearances aren’t everything, and archaeology is basically about brushing off the grime to uncover what’s valuable underneath. So, with that in mind, it’s time to dig in.

John Hunter and Galileo’s Secrets plays on a classic 5×3 matrix with 10 paylines, awarding standard wins on adjacent reels from the left, while non-adjacent wins can also land thanks to the Mystery symbol mechanic. Stakes run from 10 c to $/€250 per spin, and there are two bonus buy options available. At the top setting, the RTP is 96.5% whether you spin normally or use either bonus buy, and the volatility is high.

John Hunter himself is the best-paying symbol, delivering 100x the bet for 5 OAK. Alongside him, ink quills, parchment, telescopes, hourglasses, and globes make up the remaining premium icons, paying 15 to 75 times the bet for five on a line. Completing the paytable are the J-A royals, which return 7.5 to 10 times the bet for 5-of-a-kind. Notably, John Hunter and Galileo’s Secrets doesn’t include wild symbols, so there’s no substituting in play.

John Hunter and Galileo’s Secrets: Slot Features

John Hunter and Galileo’s Secrets comes packed with full-reel Mystery symbol reveals, a hold ‘n win respins round, free spins featuring a loose ‘Book’ style element, plus bonus buys.

Mystery Symbol Feature

Whenever a Mystery symbol lands fully stacked, every position in that reel changes into one random pay symbol or a Money symbol. Symbols created from full Mystery reels pay on all reels, including from non-adjacent positions, after line wins have been paid. If full Mystery reels reveal enough Money symbols, the respin feature is triggered.

Respin Feature

Money symbols can appear with values from 1x to 5,000x the bet, or they may include the chance to trigger free spins or super free spins. Landing 6 or more Money symbols activates the respin feature. All standard symbols disappear, meaning only Money symbols remain. Players receive 3 respins, during which only blanks or Money symbols can land. Any new Money symbol that hits resets the respin counter. Collected Money symbols stay on the screen until the feature finishes. The round ends when there are no empty spaces left or the respins are used up, and the combined value of all visible Money symbols is paid out. If the grid becomes completely filled, an extra 2,000x is awarded. Any Money symbols that contain free spins or super free spins will grant the relevant round once the respins feature concludes.

Free Spins

Landing 3 scatter symbols starts the free spins bonus. Before it begins, one pay symbol or a Money symbol is randomly chosen to act as the Mystery symbol for the entire round. Hitting 2 scatter symbols plus a super scatter symbol launches super level free spins. In the super version, the Mystery symbol is always the Money symbol, and there is no option to gamble before the round begins.

If J-A becomes the mystery symbol, the free spins feature runs as a Bronze level round. If a quill, parchment or telescope is selected, it becomes a Silver level round, while choosing an hourglass, globe, or John makes it a Gold level round. If the Money symbol is selected, the bonus is categorised as Super level.

Before free spins start, players can gamble to increase the Mystery symbol to the next higher-paying symbol or advance to the next level. Alternatively, you can accept the current Mystery symbol and begin the round immediately. A failed gamble forfeits the round.

While free spins are running, Mystery symbols nudge into full stacks and then reveal the selected Mystery symbol. The respin feature triggers instantly if enough Money symbols are uncovered. Any scatter symbols that land are collected into a meter. Each set of 4 scatters collected upgrades the level to the next one up, meaning a new symbol from that tier becomes the Mystery symbol, and +2 free spins are added.

Feature Buy

The free spins feature can also be accessed directly from the base game via a purchase option. Standard free spins cost 80x the bet, while super free spins can be bought for 200x the bet.

John Hunter and Galileo’s Secrets: Slot Verdict

Reviewing John Hunter and Galileo’s Secrets felt a bit like reuniting an old crew. For one thing, the presentation looks old—older than you’d expect given the release timing—and since Pragmatic Play is known for strong visuals, that choice seems deliberate. Was it meant to appeal to traditional players, to honour earlier slot styles, or to lean into a nostalgic mood? Take your pick. Even so, what initially seemed underwhelming started to click more once the paytable and features were explored and then watched in action. Somewhat more, at least.

In terms of gameplay, John Hunter and Galileo’s Secrets also leans heavily into familiar territory. The respins feature is as classic as they come, with no extra symbol types complicating things—just the straightforward chase of landing Money symbols while everything else is removed. It does, however, offer a hefty extra 2,000x on top of other winnings if the respins grid ends up fully covered, which could make near-misses feel especially tense. This contributes to the overall win potential, capped at 5,000x the stake. Then there are the full-reel Mystery symbols, which can reveal icons that pay across all reels from any position, adjacency irrelevant, in a Book or Ra Deluxe style. That said, John Hunter and Galileo’s Secrets doesn’t follow the exact template of a standard Book slot, and the free spins upgrades add a bit of variation that can shift how the bonus plays out.

Super level free spins also seemed to set off the respins feature fairly often, which may be a key attraction for some players. John Hunter and Galileo’s Secrets isn’t among Pragmatic Play’s most boldly modern releases, but its familiar lead character and throwback approach could suit anyone in the mood for a more old-school session.
