Sherlock of London Slot Review by Rabcat

Sherlock of London Slot Review by Rabcat

Sherlock of London is a cartoon style detective slot from Rabcat. Microgaming announced it in July 2019 as an exclusive for its operators. The game gives Sir Arthur Conan Doyle’s detective a humorous makeover.

It runs on five reels and 25 paylines. Three bonus features keep the action moving: connecting wilds, double wins and bonus spins. A free spins round adds expanding wilds.

This review covers the symbols, the wilds, the free spins and the bet range. It also explains who the slot suits.

Sherlock of London at a Glance

Theme, Graphics and Sound

The slot takes you back to the 1890s. Misty streets, gas lamps and crime fill the screen. The art style is cartoon like, so the mood stays light.

Rabcat also made Castle Builder II and Crystal Rift. It shows the same eye for clean animation here. The characters move with a playful energy.

The card symbols 10, J, Q, K and A are special. They carry the look and architecture of the period. As a result, even the low payers fit the setting.

Betting Range

Bets run from $0.25 to $50 per spin. That suits most budgets. The game has medium volatility, so wins arrive at a steady pace.

The maximum win is 2,000 times your stake. At the top bet, that equals $100,000. A lower stake gives you more spins and a longer session.

Symbols and Paytable

To win, land three to five matching symbols on a payline. The character symbols are Dr Watson, Inspector Lestrade, Irene Adler and Moriarty. The top basic symbol is the plaque for 221B Baker Street.

Here are the payouts for five on a payline.

Values are multiples of your line bet. Check the in-game paytable for the full list.

Sherlock Holmes Wild

The wild is Sherlock Holmes himself. He replaces all other basic symbols and brings extra wins. He also drives three features.

Connecting Wilds

When two or more wilds land on the same spin, they link to each other. A trail of wilds forms between them. That trail converts nearby symbols and creates wins.

Double Win

When two wilds land on adjacent reels, the game doubles the line wins for that spin. You get a 2x multiplier on top of the normal payout.

Bonus Spins

This feature is also called Re-Spins. Land a wild on reel one or reel two, and you receive one or two bonus spins. The wild stays locked in place during these spins.

A locked wild can then trigger the Double Win or Connecting Wilds again. This combination is the base game’s best route to a strong payout.

Dual Scatter Symbol

Holmes and Watson act as the scatter symbols. Land three or more to start the free spins. Dr Watson also works as an extra wild in the bonus round.

Free Spins with Expanding Wilds

Three or more scatters give you 10 free spins right away. In this round, any wild that lands expands to fill the whole reel. An expanded wild can then trigger the Double Win or Connecting Wilds.

Dr Watson also works as a second wild during the round. However, he does not trigger the extra features. He simply substitutes for standard symbols and gives you more winning combinations.

The round can retrigger. Three more scatters add another 10 spins. In total, you can collect up to 20 free spins.

How a Session Feels

The base game moves at a relaxed pace. Small wins come from the character symbols. Wilds then stretch those wins with links and doubles.

The free spins round is the highlight. Expanding wilds, connecting trails and double wins can combine in one spin. A strong round can reach the 2,000x cap.

Medium volatility keeps the game fair for most budgets. You will not face long dry spells very often, though a quiet stretch can still happen.

How to Play Sherlock of London

Pick your bet first, from $0.25 to $50. Then press spin. The game uses 25 fixed paylines, so your stake covers every line.

Wins pay from left to right. You need three to five matching symbols on a payline. The wild features trigger by themselves, so you do not need to press anything extra.

Most casinos include an autoplay option. Set a loss limit before you switch it on.

Why Wild Features Matter Here

Most of this slot’s action revolves around the wild. Connecting wilds, double wins and bonus spins all start from Sherlock. That keeps the base game lively without a separate bonus round.

As a result, even a quiet stretch can end with a sudden chain. Two wilds on the right reels can double a win and link a trail. One of them can then lock in for a respin.

Rabcat built the game around that idea. The wilds do the heavy lifting, while the free spins add an extra layer on top.

Strategy and Bankroll Tips

• Pick a stake that gives you at least 150 spins.
• Watch the first two reels for wilds.
• Aim for the free spins, where wilds expand.
• Set a loss limit before you start.
• Take regular breaks.

No system beats a slot. Each spin is random, and past results never affect the next. Treat play as entertainment.

Mobile and Demo Play

The slot runs on phones and tablets in a mobile browser. Nothing needs downloading. The 5×3 grid reads clearly on small screens.

Many casinos offer a free demo. Demo mode uses play money. It lets you watch how the wilds link up before you stake real cash.

Playing Responsibly

A fun theme can make time fly. Set a budget before you start and keep to it. Use deposit limits and reality checks if your casino offers them.

Never chase losses. Stop if gambling stops being fun.
