Sherlock and the Stolen Gems

Sherlock and the Stolen Gems Overview

Sherlock and the Stolen Gems is a Red Rake cluster-pays game played on a large square grid in Victorian London. It has no paylines, no ways and no fixed prize ladder on screen – clusters of matching gems are counted wherever they fall, and the board cascades.

Its maximum win is 1,290x the bet, which is modest by current standards and, as usual, tells you a good deal about how the rest of the game behaves.

Theme and Graphics

The reels stand in a gaslit street. A green enamel BAKER STREET sign hangs on the left wall beneath the words City of Westminster, a wrought-iron lamp burns on the right, and the buildings recede into fog behind the grid. It is painted rather than rendered, and the light is genuinely good.

The symbols are cut gemstones in purple, blue, green, red and yellow, and above them a cast of characters: Sherlock in his deerstalker, a moustached Watson, a beaming Mrs Hudson, a bulldog and a raven. A gold pocket watch marked WILD sits among them.

All figures below come from demo play at a 10.00 EUR bet.

Clusters and Cascades

Matching gems pay wherever they land, and the winning group is removed so the board refills from above – the standard avalanche arrangement, and the reason a single spin can resolve into a chain.

What makes it worth watching here is the scale of the grid. On a board this large a single colour can take over most of it, and the demo catches exactly that: one capture shows purple gems filling something close to forty positions, with only a handful of characters and a stray green stone interrupting them.

That board paid 162.50 against the 10.00 stake – 16.25 times the bet. A second, similar board with two wilds among the purple paid 212.50, or 21.25x.

Those are the two best results in the session, and both came from saturation rather than from a premium symbol.

What the Ordinary Spins Pay

The rest of the captures show the other side of the distribution. A board of blue diamonds with characters scattered through it paid 3.82 – 38 percent of the stake. A board of bulldogs paid 1.34, or 13 percent.

A mid-sized board of blue gems with a wild and a floating 12.50 marking one cluster paid 40.32, or roughly four times the bet.

So the spread in the session runs from 0.13x to 21.25x, and three of the five results returned less than half the money staked. On a cluster game with a grid this size, small clusters are the norm and they are worth very little.

The Giant Symbol

One capture shows something different: the grid dimmed to near-black with a single enormous portrait filling the centre – a sharp-featured man in a pinstripe suit holding a cane and a glowing orb, framed in a swirl of green light.

It is Moriarty, and he arrives as a giant symbol several positions across rather than as a tile. On a cluster game a block that size converts a substantial share of the board at once, which is a different kind of event from anything the ordinary gems can produce.

The London Map

The other special screen is the best piece of art in the game. The reels are replaced by a folded plan of London, pinned at half a dozen points, with red thread strung between the pins to form a pattern across the city. Sherlock stands in front of it with his pipe, and Moriarty’s face is sketched in the corner.

Three gems sit along the bottom edge of the map – green, purple and blue – which suggests a collection running across the round rather than a single pick.

The demo’s balance rises from 1,105.00 to 1,145.00 across that screen, so the round it belongs to resolved at four times the stake. The feature list attached to the title adds free spins, a hold-and-win round and respins to the cascade, so the map is one component of a larger feature set rather than the whole of it.

RTP, Volatility and Max Win

The RTP is 95.2%, which is below the modern standard of roughly 96% – not dramatically, but enough to register over a long session.

Volatility is rated Medium and the maximum win is 1,290x the bet – an oddly precise figure and a low one. Many current releases quote five thousand or more.

Medium fits the demo. The balance drifts between 921 and 1,145 across the captures without any lurch in either direction, and the results cluster in a narrow band once the two saturated boards are set aside.

The low ceiling is the honest consequence of the rest. There is no multiplier ladder visible in the captures, no jackpot plates and no buy menu; a cluster game without a multiplier mechanic cannot reach the five-figure multiples that its contemporaries advertise, because the only thing that scales is how much of the board one colour has taken.

What it does offer is a genuinely handsome piece of work. The Baker Street setting is painted with care, the map screen is the best-looking bonus interface in this batch, and a 1,290x ceiling on a Medium game is at least a promise the design can actually keep.
