Holmes and the Stolen Stones is a detective-themed video slot developed by Yggdrasil. The game uses five reels and 20 fixed paylines, combining traditional line wins with a Warehouse pick feature, persistent diamond-shard collection, Jackpot Free Spins and five local progressive jackpots. Its official RTP is 96.8%, while Yggdrasil classifies the volatility as low.
The main attraction is not a complicated reel mechanic. Holmes and the Stolen Stones focuses on collecting diamond shards and unlocking a jackpot round in which five diamonds of the same colour award the corresponding progressive jackpot. This structure may appeal to players who prefer visible long-term progress, straightforward paylines and several bonus objectives instead of cascading reels or complex multiplier systems.
Quick verdict:
- Holmes and the Stolen Stones has a classic 5-reel, 3-row layout with 20 paylines.
- The official RTP is 96.8%, although the value should still be checked inside the casino version.
- Yggdrasil lists the game as low volatility.
- Five local progressive jackpots are connected to five diamond colours.
- Jackpot Free Spins provide 10 spins with a 3x multiplier on regular wins.
- There is no standard Wild symbol, so most base-game wins depend on natural symbol combinations.
- Mobile play is supported on compatible Apple and Android devices.
Holmes and the Stolen Stones is usually more suitable for players who enjoy jackpot collection systems, classic paylines and lower-volatility gameplay. Players looking for frequent expanding Wilds, bonus buys, cascading combinations or extremely high multiplier wins may find the structure dated compared with newer slots.

Theme, graphics and presentation
Holmes and the Stolen Stones takes place in a dark interpretation of Victorian London. Holmes and Watson search for missing gemstones among foggy streets, keyholes, warehouse crates, notebooks and detective equipment. The game does not closely reproduce a particular Arthur Conan Doyle story, but it uses recognisable detective imagery to create a clear mystery theme.
The visual design is more muscular and stylised than a traditional Sherlock Holmes adaptation. Holmes and Watson appear as action-oriented investigators rather than reserved Victorian gentlemen. The atmosphere is supported by shadowed backgrounds, metallic reel borders and suspenseful audio.
The presentation remains readable because the important collection information appears above the reels. Players can see five progressive jackpot values and the status of the coloured diamond shards without opening a separate menu. This is useful because the collection system is central to the game rather than a minor side feature.
How the base game works
Holmes and the Stolen Stones pays when three or more matching regular symbols appear on adjacent reels along an active payline, beginning with the leftmost reel. The game has 20 fixed paylines, so changing the stake changes the total wager rather than the number of active lines.
The symbol set contains four character or detective-related symbols and four lower-value card-suit symbols. Holmes is the highest-paying regular symbol, followed by Watson, a notebook and a magnifying glass. The lower symbols use spades, hearts, diamonds and clubs.
Holmes and the Stolen Stones does not use a traditional Wild symbol. Regular line wins must therefore be formed with matching natural symbols rather than Wild substitutions. This makes the base game simple, but it also means that the most distinctive gameplay comes from keyhole symbols, shard collection and the two bonus modes.
Warehouse Bonus feature
The Warehouse Bonus is activated by landing at least three rusty keyhole Bonus symbols. Four or five triggering symbols can also award a separate coin prize before the feature begins. The exact prize representation should be confirmed in the paytable of the version being played.
During the Warehouse Bonus, players select from 18 wooden crates. The crates can reveal coin prizes, coloured diamond shards or a smoke bomb. Coin prizes are added to the feature result, while collected shards move to the corresponding meters above the reels. Finding the smoke bomb ends the selection round.
The Warehouse Bonus matters because it supports two objectives at once. It can produce an immediate prize, but it can also advance the persistent shard meters that lead to Jackpot Free Spins. A round with modest cash rewards may therefore still contribute to a later feature.
The crate-selection order should not be treated as a strategy for controlling the outcome. Pick features are chance-based, and choosing a particular position does not provide a reliable way to locate better prizes.
Diamond Shard Collection
The Shard Collection feature tracks five colours of diamond fragments above the reels. Shards may appear through normal gameplay and inside the Warehouse Bonus. Collecting five shards of one colour completes the corresponding diamond and activates Jackpot Free Spins.
The shard system gives Holmes and the Stolen Stones a stronger sense of progression than a basic 20-payline slot. Instead of waiting only for three bonus symbols, players can see their collection moving closer to a feature trigger.
Some versions preserve collected shards between sessions, but players should verify this behaviour with the selected operator. Account status, game configuration and technical storage rules can affect whether progress remains available after the game is closed.
A nearly complete meter does not mean that the final shard is due. Every spin remains random, and visible progress should not be used as a reason to increase the stake or extend a session beyond a preset limit.
Jackpot Free Spins
Jackpot Free Spins can be activated by landing at least three golden keyhole symbols or by completing a five-shard diamond meter. The feature awards 10 free spins, and regular line wins during the round are multiplied by 3.
When Jackpot Free Spins are triggered through shard collection, the corresponding diamond colour begins the feature with progress already recorded. During the round, complete coloured diamonds can appear. Collecting five diamonds of the same colour awards the progressive jackpot linked to that colour.
The 3x multiplier increases the value of ordinary symbol wins, but it does not guarantee a profitable bonus round. The main jackpot condition still depends on collecting enough matching diamonds within the available spins.
Jackpot Free Spins cannot normally be retriggered, according to commonly published game rules. Players receive one fixed sequence of 10 spins and must complete a same-colour diamond set during that sequence to win a jackpot. The current in-game rules remain the final reference.
How the five progressive jackpots work
Holmes and the Stolen Stones includes five local progressive jackpots. Each jackpot is associated with a different diamond colour, and its displayed value can grow as qualifying wagers are placed on the same operator network. Because the jackpots are local rather than global, their values can differ between casinos.
A jackpot is awarded by collecting five diamonds of one colour during Jackpot Free Spins. Collecting shards in the base game does not directly award the jackpot. Shards help activate the free-spin mode and can provide initial progress, but the required full diamonds must still be collected during the bonus round.
Progressive values should be viewed as possible prizes, not as indicators that a jackpot is likely to trigger soon. A larger displayed amount does not reveal when the jackpot will be won, and previous spins do not make a particular colour more likely on the next spin.
RTP, volatility and maximum win
Holmes and the Stolen Stones has an official theoretical RTP of 96.8%. RTP describes the percentage of total wagers that a game is mathematically designed to return across a very large number of plays. It does not predict the result of an individual session, and a player can finish far above or below the theoretical percentage.
Yggdrasil classifies Holmes and the Stolen Stones as a low-volatility game and describes its design as focused on relatively frequent jackpot wins. Low volatility generally means the game is structured around more regular, often smaller outcomes than a high-volatility slot. It does not mean that losses will be small or that the balance will remain stable during a short session.
The official game information lists a maximum win of EUR 30,000. Some published paytable descriptions also state that five Holmes symbols can pay 200 times the total stake in the base game, rising to 600 times the stake when the 3x free-spin multiplier applies. Jackpot values are progressive and may be displayed separately from ordinary line-win calculations.
The commonly published betting range is EUR 0.20 to EUR 40 per spin, but actual minimum and maximum stakes can depend on the operator, account currency and jurisdiction. A casino may also offer a different certified RTP configuration, so the information screen should be checked rather than assuming that every version is identical.
Base game, Warehouse Bonus and Jackpot Free Spins compared
| Game stage | Main purpose | Main risk or limitation |
| Base game | Form line wins and collect diamond shards | No standard Wild symbol |
| Warehouse Bonus | Reveal coin prizes and additional shards | A smoke bomb ends the feature |
| Jackpot Free Spins | Receive 10 spins with 3x regular wins and pursue jackpots | A jackpot still requires five matching diamonds |
| Progressive jackpot collection | Win one of five colour-coded prizes | Jackpot timing cannot be predicted |
Holmes and the Stolen Stones works best when these stages are understood as connected parts of one system. The base game builds shard progress, the Warehouse Bonus can accelerate collection, and Jackpot Free Spins provide the only opportunity to complete the full jackpot condition.
Who may enjoy Holmes and the Stolen Stones?
Holmes and the Stolen Stones may suit players who prefer traditional paylines but want more structure than a completely basic slot. The visible shard meters create a continuing objective, while the Warehouse Bonus provides a simple interactive break from regular spins.
The game may also appeal to players who prefer low-volatility slots and several progressive prizes instead of one extremely rare global jackpot. The 96.8% official RTP is another potentially attractive characteristic, although it remains a long-term theoretical figure rather than a session forecast.
Players who enjoy detective themes, darker graphics and classic character symbols may find the presentation more distinctive than a generic fruit or jewel slot.
Who should consider a different slot?
Holmes and the Stolen Stones may not suit players who want modern mechanics such as Megaways, cascading symbols, expanding Wilds, increasing multipliers or a bonus-buy button. The 2015 design is built around fixed paylines and collection meters rather than rapid chains of reel modifiers.
Players who dislike progressive jackpots may also prefer a fixed-prize slot. Part of the game’s identity is tied to pursuing colour-coded jackpots, and activating Jackpot Free Spins without completing a diamond set may feel unrewarding.
Anyone who feels compelled to continue because a shard meter is nearly complete should stop rather than chase the feature. Visible collection progress does not change the random nature of future spins.
Mobile compatibility and demo play
Holmes and the Stolen Stones is optimised for mobile play and supports compatible Apple and Android devices. The 16:9 game format adapts more naturally to landscape orientation, although the exact controls and screen scaling depend on the casino interface and device.
A free demo can be useful for learning the paylines, keyhole symbols, crate feature and jackpot conditions without wagering money. Demo availability depends on the casino, region and local rules. Demo credits have no cash value, and results in free play do not predict what will happen during real-money play.
How to choose where to play
Choose an operator that is legally available in your country and provides clear information about its licence, payments, withdrawal rules and responsible gambling tools. Worldwide availability does not mean that every casino or game is permitted in every jurisdiction.
Before playing, open the game information panel and confirm:
- the RTP offered by that specific version;
- minimum and maximum stake limits;
- the current progressive jackpot values;
- whether shard progress is saved between sessions;
- whether the game is excluded from casino bonus wagering;
- withdrawal limits and identity-verification requirements;
- deposit limits, session reminders and self-exclusion tools.
Casino bonuses should be assessed separately from the slot itself. Free spins, matched deposits and promotional balances may include wagering requirements, maximum-bet restrictions, eligible-game rules and withdrawal limits.
Common mistakes and misconceptions
A nearly complete shard meter does not make the feature inevitable. The remaining shard may appear soon, much later or not during the current session. Random outcomes do not become due because a meter looks close to completion.
Low volatility does not mean low financial risk. A low-volatility game can still consume a full session budget, particularly when spins are repeated quickly or the stake is increased.
A higher progressive jackpot does not reveal the next winning spin. The displayed value shows the current potential prize, not the probability that a jackpot will be awarded immediately.
RTP does not return 96.8% of each deposit. The percentage is calculated across a very large volume of wagers and cannot be applied directly to one player’s short session.
The Warehouse picks do not provide a repeatable winning strategy. Selecting the same crate position or following a visual pattern cannot guarantee a prize because the feature is based on chance.
Practical playing recommendations
Set a fixed spending limit before opening Holmes and the Stolen Stones, and choose a stake that allows that limit to cover the intended session. Do not raise the stake simply because a jackpot value is increasing or a shard meter is almost complete.
Use a demo first when available. The objective is to understand how the two keyhole symbols, shard meters and Jackpot Free Spins interact, not to search for a pattern that predicts real-money results.
Review the account history after a session rather than judging the result from one memorable jackpot feature. Time limits and financial limits can make spending easier to track, and recognised regulators provide information about tools for controlling gambling activity.
Holmes and the Stolen Stones should be treated as paid entertainment, not as a method of earning money. Stop playing when the planned time or spending limit is reached. Chasing losses, repeatedly increasing stakes or continuing because a feature feels close are warning signs that the session is no longer being managed responsibly.
How this information was reviewed
This Holmes and the Stolen Stones review prioritises the provider’s published game information for the release date, layout, paylines, RTP, volatility, maximum win, mobile support and core jackpot mechanism. Detailed feature descriptions were checked against published paytable summaries and casino game guides.
Players should still verify the RTP, betting limits, saved collection progress, jackpot values and feature rules inside the current game version. Operator configurations and regional availability can differ.
RTP, volatility, shard collection and progressive jackpots do not guarantee a particular result. Every spin remains random. Players who are under the legal gambling age, are using money needed for essential expenses, are chasing losses or find it difficult to stop should not play.
FAQ
What is Holmes and the Stolen Stones?
Holmes and the Stolen Stones is a Yggdrasil video slot with five reels, 20 paylines, a detective theme, diamond-shard collection and five local progressive jackpots. The game was released on September 9, 2015.
What is the RTP of Holmes and the Stolen Stones?
The official Holmes and the Stolen Stones RTP is 96.8%. This is a theoretical long-term percentage and does not guarantee that an individual player will recover 96.8% of their wagers. The value should also be confirmed in the game information because casino configurations may vary.
Is Holmes and the Stolen Stones high volatility?
No. Yggdrasil classifies Holmes and the Stolen Stones as a low-volatility slot. This may produce a different playing pattern from high-volatility games, but it does not remove the possibility of losing an entire session budget.
How do the progressive jackpots work?
The five progressive jackpots are linked to five diamond colours. A player must enter Jackpot Free Spins and collect five complete diamonds of the same colour during the feature to win the corresponding jackpot. Collecting shards alone does not guarantee a jackpot.
How are Jackpot Free Spins triggered?
Jackpot Free Spins can be triggered by landing at least three golden keyhole symbols or by completing a set of five matching diamond shards. The feature normally provides 10 free spins with a 3x multiplier on regular line wins.
Does Holmes and the Stolen Stones have a Wild symbol?
No traditional Wild symbol is listed in the standard game rules. Regular line wins are formed with matching natural symbols, while the main special symbols activate the Warehouse Bonus and Jackpot Free Spins.
What happens in the Warehouse Bonus?
The Warehouse Bonus allows the player to select wooden crates containing coin prizes, diamond shards or a smoke bomb. Collected shards advance the meters above the reels, while finding the smoke bomb ends the selection feature.
Can Holmes and the Stolen Stones be played on mobile?
Yes. Holmes and the Stolen Stones is optimised for mobile play and supports compatible Apple and Android devices. Availability still depends on the casino, device, browser and country.
Can Holmes and the Stolen Stones be played for free?
A demo version may be offered by some casinos and game-information websites, but availability depends on the operator and regional rules. Demo play can explain the mechanics, but demo results do not predict real-money outcomes.
Can a strategy guarantee a jackpot?
No strategy can guarantee a jackpot in Holmes and the Stolen Stones. Spin results, crate outcomes and diamond collection are chance-based. Increasing the stake, repeating the same selections or continuing because a meter is nearly complete cannot guarantee a win.
Brief conclusion
Holmes and the Stolen Stones is a low-volatility Yggdrasil slot built around 20 paylines, a 96.8% official RTP, persistent shard collection and five local progressive jackpots. Its strongest feature is the connection between the Warehouse Bonus, diamond meters and 10 Jackpot Free Spins with a 3x multiplier.
The game is most suitable for players who enjoy classic reel structures and visible collection progress. It is less suitable for those seeking modern cascading mechanics, frequent Wild modifiers or extreme fixed multipliers. Check the current paytable and casino terms before playing, set firm limits and treat every spin as entertainment rather than an opportunity to earn money.
