Sherlock's Casebook Slot: Demo Play, Review, Casinos List

Sherlock's Casebook is a 1x2 Gaming 25 fixed payways, Medium variance release, which provides a RTP of 96.0 % and x100 as the maximum available win (published on July 3, 2019). Those are the features of this slot machine: Free spins, Wild, Scatter.

An Intriguing London Caper

I believe Sherlock’s Casebook brings a nostalgic detective story to life with neat visual flair. The game arrived on July 3, 2019, thanks to 1x2 Gaming, and the whole slot has a “books” theme that references the investigations of a certain famous sleuth. You’ll see 5 reels and 3 rows filled with symbols like a pipe, a violin, and the 221B Baker Street sign, each in a steady left-to-right pay format. That 221B sign pays the most among regular icons, showcasing bright letters against a misty London backdrop.

In my experience, the sound design fits the mystery vibe by slipping in soft background tunes and a breezy soundtrack that occasionally shifts to more dramatic pulses whenever bigger wins appear. I did not minded the overall style, since it’s neither dull nor overly flashy. Mobile play is also possible, so if you want to spin on a phone or tablet, the interface should scale just fine. I find that the controls are easy to manage; you can set your stake without rummaging through complicated submenus. If you like historically inspired slot designs, the moody London streets in the backdrop might keep you entertained.

Where Mystery Meets Mechanics

I think the core storyline here revolves around famous detection tasks in Victorian London. There’s even a sense of steampunk thrown in, with Sherlock donning quirky goggles on his iconic deerstalker. Anyone who enjoys a well-structured layout should be comfortable with the 25 paylines, each capable of forming a winning combo as soon as you line up three or more matching icons from left to right. The top possible win is x100 of your stake, so some high-risk fans might find that smaller than usual.

Regarding bets, you can pick an amount between 0.25 EUR and 100 EUR each spin. That feels wide enough to include both cautious bettors and those seeking bigger per-spin wagers. In my view, the interface is straightforward, and the spin button is usually front and center, so you won’t have trouble giving it a whirl. The slot is 5x3 in structure, and I found the pace to be moderate. If you prefer short bursts of action, there’s an option to switch on quicker spins. Personally, I like the standard spin speed because it allows me to enjoy the ambiance a bit more.

RTP And Volatility Observations

Sherlock’s Casebook offers a 96.0% RTP, which I consider decent for long-term play since it often indicates a balanced house edge. This slot hails from 1x2 Gaming, and I haven’t heard of them using adjustable/floating RTP, so I assume that 96.0% is reliable wherever you might play. Even with a respectable return rate, though, it’s always wise to check any game details at your chosen casino to ensure you’re spinning the same version the developer released.

Medium volatility definitely influences the style of gameplay. That trait often balances moderate hits along with an occasional bigger reward. I see that as a plus for players who want to see wins appear fairly regularly without sacrificing all potential for a chunkier payout. If you are aiming to get the best from a medium slot, I'd keep around 200 bets in your balance so you can weather any lean patches before the free spins or bigger line wins emerge. I personally prefer higher volatility, but I know a bunch of slot enthusiasts who like a steadier approach that medium volatility can offer.

Free Spins On The Case

This slot doesn’t feature a separate Bonus Game and Bonus Symbols, but it does include Free Spins. To trigger them, you need three or more Irene Adler Scatter symbols to land anywhere. The reward structure is fairly simple:

• 3 scatters grant you 10 free spins
• 4 scatters award you 15 free spins
• 5 scatters deliver you 20 free spins

During these free spins, Dr Watson shows up as a sticky wild that can remain on the reels for an extra spin once it appears. This can open a route to building multiple wins in quick succession if you catch a couple of Watson icons early on. I like how Sherlock’s expanding wild is still active in free spins, but it won’t expand on a reel that houses a sticky wild. That detail keeps the excitement going without oversimplifying the mechanics. Honestly, I’ve seen more elaborate free spin setups, but the presence of two types of wilds in a single bonus feature is pleasing enough for me.

Other Investigative Tools

• Scatter Symbol: Represented by Irene Adler, and it’s the trigger for the free spins. Even if you don’t land enough for the feature, a couple more Adler symbols can sometimes appear to tease the possibility of hitting it next time.

• Wild Symbol: Sherlock Holmes icon acts as a reel-transforming wild. Each time he lands, he becomes an expanding wild and covers the entire reel, replacing all normal pay symbols. I find that can bump up your base game wins significantly on a lucky spin.

• Sticky Wild: Dr Watson only shows up during free spins, and every time he appears, he clings to the reel for the next spin. That extra hold can produce two consecutive spins with decent outcomes if you’re fortunate enough to line them up with matching icons.

Likes And Dislikes
