Sherlock & Moriarty WOWPOT! is a detective-themed progressive jackpot slot from Just for the Win, set on a 5-reel, 20-payline grid and driven by mystery symbols, streak-style respins, and a free spins bonus feature with pickable upgrades such as sticky wilds, extra spins, and a rising multiplier.…
Sherlock & Moriarty WOWPOT! combines a dark Victorian detective theme with a progressive jackpot chase that stays relevant on every spin. The core gameplay is easy to follow on a 5-reel, 20-payline grid, but the slot adds depth through question-mark mystery symbols, a streak-style respin mechanic, and a free spins bonus feature where you select upgrades that can reshape the round. The star attraction is the WowPot jackpot wheel, which awards one of four progressive tiers when it triggers.
The presentation leans into foggy London streets, sepia lighting, and a tense soundtrack that matches the rivalry between Sherlock and Moriarty. Premium symbols focus on the lead characters, while lower icons keep the reel face readable and consistent. Feature moments are clear: mystery symbols flip with a distinct reveal, respins announce themselves with a short build-up, and the jackpot wheel arrives as a full-screen event designed to feel separate from routine line wins.
This slot uses five reels with three rows and 20 fixed paylines, so wins are evaluated in a familiar left-to-right line format rather than ways-to-win math. That structure makes it easy to connect what you see to what you’re paid, which is useful because the main complexity comes from features, not from the reel model. Stakes start low enough for careful demo testing and scale up to higher wagers for players who want faster progress toward the jackpot mechanics.
Because paylines are fixed, you are not toggling lines on or off; you mainly set your total stake and let the feature system do the heavy lifting. The interface is simple on both desktop and mobile, with clear buttons for spin, autoplay, and pay information. If you like predictable evaluation but still want modern enhancement features, this setup hits a good middle ground.
Line wins come from a mix of character symbols and lower-value icons, with wilds acting as substitutes for regular pay symbols to help complete paylines. The paytable feel is typical for a progressive-led slot: plenty of small-to-mid hits keep the session moving, while standout returns are more dependent on feature involvement than on raw base-game line frequency. In other words, the base game gives you activity, but the bigger spikes usually happen when mystery symbols, respins, or free spins stack value.
Most spins play quickly, and the slot’s personality shows up when the question-mark mystery symbols appear. Sometimes they simply add surprise value by converting into a single matching pay symbol, which can complete paylines that were already close. Other times they become a trigger point for extended action, where the slot pauses the regular spin cadence and switches into a short feature sequence aimed at improving the final outcome. That keeps the base game from feeling like pure waiting between bonuses, because you regularly get “something to watch for” even in ordinary spins.
Mystery symbols are the main base-game lever. When a small group lands, they commonly resolve into the same randomly chosen paying symbol, so a modest mystery hit can still turn into a respectable line win if it aligns with existing symbols. When a larger group appears, the game can launch Mystery Streak Respins, effectively giving you extra attempts to build a stronger screen. This mechanic feels like a compact bonus feature inside the base game: it creates suspense, extends the opportunity window, and can turn what would have been a standard conversion into a noticeably better paid result.
The important practical point is that these respins are not just cosmetic. They are one of the ways the game redistributes value into feature moments, which is why your sessions often alternate between quick routine spins and short bursts where the slot tries to convert a promising setup into a better-paid finish.
The free spins bonus feature is the most interactive part of the game because it lets you choose upgrades that influence the round. The choices are straightforward and meaningful: one option can add a sticky wild that remains in place for the entire bonus round, another can increase the global multiplier by +1, and another can award extra free spins. Those upgrades can be offered as “extras” during the bonus, so the round can evolve as you play, rather than feeling locked into a single preset format.
Sticky wilds favor steady line completion, extra spins raise the number of chances you have to catch premium alignments, and multiplier growth creates the classic late-round pop where later wins can outpace earlier ones. If you enjoy bonuses that feel different from one trigger to the next, these upgrade picks do a lot of work without requiring complicated decision-making.
The WowPot mechanic is the defining hook: four progressive jackpots are available, and the jackpot wheel guarantees one of the tiers when it activates. Progress toward that moment is linked to magnifying-glass tokens that appear in connection with premium-symbol activity on the middle reels. Over time, token collection makes the jackpot chase feel tangible because you can see your involvement building, rather than relying on a completely hidden trigger.
The wheel trigger itself is random, but stake level influences how quickly tokens accumulate, so higher wagers tend to accelerate the journey. Importantly, the wheel is not a “spin to maybe win something” event; when it fires, you receive a progressive jackpot award. That clear promise is what separates the slot from many pseudo-jackpot features that offer a wheel only to deliver mostly small prizes.
As a progressive title, the game’s long-run return is designed with jackpot funding in mind, which shows up in its stated return percentage: RTP: 92.10%. That figure describes the expected share of total stakes returned over very large samples through standard line wins and feature outcomes, while the progressive wheel sits as a separate, rare event that can dwarf routine payouts when it arrives, effectively concentrating much of the excitement into the jackpot layer.
In day-to-day play, a meaningful portion of the return tends to come from the base game’s frequent small hits plus the intermittent boosts from mystery-symbol conversions. Mystery Streak Respins are a key contributor because they can take a nearly-there screen and provide extra chances to turn it into a paid finish. Free spins then supply the most memorable non-jackpot swings, because sticky wilds and added spins can extend value while the +1 multiplier upgrade raises the ceiling for each subsequent line hit.
What you experience mechanically is a rhythm of steady but modest base outcomes punctuated by sudden “upgrade moments.” A single mystery conversion can create an unexpected medium win, while a respin run can shift a quiet stretch into a short cluster of improving results. In free spins, the feel is more build-oriented: sticky wild placement can make paylines more reliable, and multiplier growth makes later spins feel higher leverage. Tokens add another feedback loop, giving you visible progress even when the win size is small.
Volatility is best described as medium, because you can expect regular activity from line wins and mystery behavior, but the standout results are more dependent on landing the right combination of bonus upgrades or hitting the wheel at all. The slot does not try to deliver constant big multipliers from the base game; it asks for patience and rewards it with feature-driven bursts that can arrive unpredictably.
For regular reel outcomes, the highest non-jackpot results are commonly framed as topping out around 200× bet on a single spin before bonus-round multiplier growth is considered. That controlled ceiling is intentional: it keeps routine wins in check so the progressive jackpots remain the clear peak of the pay model. If you’re here for the wheel, this trade-off makes sense; if you want massive non-progressive max wins, you may prefer a different style of slot.
On mobile, the 5×3 grid stays readable and the feature messaging is clear, which matters because this slot relies on quick state changes like mystery flips, respin sequences, and bonus upgrade picks. Buttons are large enough for one-handed play, and the token tracking for the jackpot mechanic is visible without blocking the reels. Performance is smooth on typical devices, and the bonus selection screens are easy to tap accurately, making mobile play a genuine equal to desktop rather than a compromised port.

Demo sessions also help you decide whether you prefer a slow-and-steady token chase or a higher stake level that pushes you toward more frequent jackpot involvement.
After you’ve learned the rhythm, switching to playing for real money is mainly about whether you value progressive potential.
