It seems like developers have revived Sherlock’s popularity recently, based on the recent releases inspired by the legendary detective. 1x2 Gaming is one of the developers who released a Sherlock Holmes-inspired slot, one that offers impeccable visuals and straightforward gameplay that can take you to some decent wins, called Sherlock’s Casebook.


You form winning combos on the reels by landing matching symbols on consecutive reels from left to right. This rule does not apply for special Scattered symbols, as they count anywhere they land.

Sherlock himself is the Wild in the slot, which expands to cover the entire reel it lands on, and substitutes for all non-special symbols in the formation of winning combos.

One of the special Scattered symbols is the Queen, which appears in the base game only. You will need to land 3, 4 or 5 Scattered Queen symbols in order to trigger 10, 15 or 20 Free Spins. During the Free Spins, you will see a different Wild appearing on the reels, the special Watson Wild symbol. It will substitute for non-special symbols, too, but will also stick on the reels for the next Free Spin whenever it lands. Therefore, Watson will act as a Sticky Wild.

While the Expanding Wild can appear on the reels during the Free Spins, it cannot appear if there was already a Sticky Wild present on that reel.

Theme & Design

The first thing you will notice as you take a look at the transparent reels is that there is an animation of a train passing behind the reels. There are two other moving hot air balloons on the top left of the reels, and you will see two pipes with steam coming out of them on the left bottom corner of the screen. On the right, you can see Sherlock’s popular house, and on the reels, you will even see the sign of the street he lives in.

So, on the reels, you will see the lowest-paying playing cards J, Q, K and A, the latter giving you 50 coins for the best combo. Then, you see Sherlock’s epic hat with glasses on it giving you 150 coins, as well as his smoking pipe giving you 300 coins. The violin gives you 400 coins, while the revolver 600 for a 5-of-a-kind combo. The magnifying glass gives you 800 coins, while the highest-paying 221B Baker St. sign gives you 1,000 coins.

Wagering & Paylines

There are 25 paylines in the slot, which are fixed, and you’re playing with them all with 1 coin per line. Considering the betting range goes from $0.25 to $100.00, it means that the minimum coin value goes from $0.01 to $4.00. The RTP the game offers is 96.00%.

Now, considering the max coin value is $4.00, it means that you will need to multiply it by the payouts in the paytable for each symbol. Therefore, the lowest-paying symbols can give you $200.00 for the max bet, while Sherlock’s hat $600.00. His smoking pipe can give you $1,200.00 while the violin $1,600.00 for the best combo. The revolver will deliver $2,400.00, and the magnifying glass $3,200.00. The highest-paying 221B Baker St. sign can deliver the top payout of $4,000.00 per spin.

Considering that you will get the help of the Expanding and Sticky Wilds, and you’ll get up to 20 Free Spins, you should expect plenty of successful, winning spins and some really solid rewards from this slot.


Sherlock’s Casebook turned out to be quite a charming casino game. You will be impressed by its design and graphics, and you’ll appreciate the symbols and their connection to Sherlock and his investigative work. You’d be glad to see that Watson is present on the reels as well, as it is Sherlock’s street sign. But, what you’ll love the most is the simplicity of the gameplay that can actually take you to rewards of $4,000.00 per spin. There are 20 Free Spins you can trigger, so the game can actually deliver up to $80,000.00 during the Free Spins bonus alone. If you’re a fan of Sherlock and a slots player, we recommend you to give this slot a try.
