Sherlock and the Stolen Gems

Sherlock and the Stolen Gems is a video slot from Red Rake Gaming with a 6×6 symbol grid that can expand to 8×8 under certain conditions. The game uses Cluster Wins instead of classic paylines: you need at least seven matching symbols that are connected horizontally or vertically to trigger a win. With each win, the Cascading Reels mechanic is activated, causing the winning symbols to disappear and new ones to fall from above, allowing for chain reactions.

The Sticky Clusters feature ensures that won clusters remain fixed while the remaining fields respin; during these respins, the clusters can even grow larger. The Expanding Sherlock feature is triggered when a win is completed: Sherlock expands the game grid to 8×8 and grants a respin on this expanded board. Morgan's rival Moriarty also appears: his feature transforms the symbols around him into identical ones, creating a 3×3 cluster.

The free spins round starts as soon as three or more bonus symbols appear. In the free spins, the game is permanently set to the 8×8 grid. There is the Big Ben bar, where bonus symbols can be collected; it grants additional free spins and multipliers throughout the free spin phase. The theme is a classic detective case set in Victorian London, with atmospheric design, jewel symbols, and iconic characters like Sherlock and Moriarty. Graphically and technically, the game is optimized for desktop and mobile devices, running in HTML5.
