Slot Summary

Completing a set of matching diamond shards is the decisive act in Holmes and the Stolen Stones, because the collection opens Yggdrasil Gaming's jackpot mode with a head start toward the corresponding prize. Released in 2015, the Detective slot connects that persistent search with a warehouse pick game, 20 paylines and five local progressive jackpots.

How It Plays

Regular wins use eight paying symbols across 20 lines, starting from the leftmost reel. The game has no Wild, so its special symbols concentrate on feature access and collection.

Diamond shards can remain recorded between ordinary spins and warehouse picks. Finishing a matching set opens the jackpot mode, connecting several rounds through one visible collection objective.

Theme & Atmosphere

The Detective and Mystery themes cast Sherlock Holmes and Watson as investigators searching for stolen stones. A dark European setting supports the case-solving premise without separating it from the prize system.

Warehouse crates, keyholes and diamond fragments turn the Exploration theme into an active search. The symbols function as clues and collected evidence rather than unrelated decoration.

Features & Win Potential

The Symbols Collection feature records diamond shards by color. Completing the required set grants access to the Progressive Jackpot mode with one matching diamond already credited.

The Bonus Game uses a Pick Objects format inside the warehouse. Cash and shard results extend the search, while selecting the smoke bomb immediately closes the sequence.

Bonus & Free Spins

The warehouse Bonus Game presents crates one at a time, allowing repeated picks until the smoke bomb appears. Any collected diamond shards transfer back to the continuing collection.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.80%), with wins capped at its top multiplier (600×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
