Yggdrasil Gaming, whose games are now available in South Africa, taps the fictional detective story from the popular writings of Sir Arthur Conan Doyle to create Holmes and the Stolen Stones, containing Jackpot Free Spins, the Warehouse Bonus Game and the Shard Collection.
While the theme is mystery-based, its popularity certainly is not with a 5-tiered progressive jackpot potentially offering thousands in prize money!
Orchestral music and Victorian architecture
Yggdrasil is one of our favourite developers because of the quality that goes into their graphics and audio, which are carefully selected to support the motif. There are snippets of Victorian architecture and the distant view of London Bridge.
The upper-value symbols include the pipe-smoking Sherlock, Dr Watson, a leather-bound journal and magnifying glass whereas the lower-value symbols include four poker suits. The orchestral music has an exciting, yet tension-building edge, which in combination with other audio effects suit the theme perfectly.
The Warehouse Bonus Game
The clues can take you in any number of directions, and one of these is the Warehouse Bonus Game. This is a feature that is triggered by three keyhole bonus symbols on any of the five reels. You can participate in the Bonus game with 3, 4 or 5 symbols and with 4 or 5 symbols, you instantly collect an additional 1,000 or 10,000 coins respectively.
Your task is to select closed crates for the chance to find one of five coloured shards of diamonds, which are stored in a meter corresponding to one of the five tiers of jackpots, or coins inside. The game ends when you open up a crate with a smoke bomb inside. We did find that this feature could be triggered every so often which made it worth the wait.
Holmes and the Stolen Stones Free Spins Feature
Another direction is the way of 10 free spins, with a 3x multiplier, which is triggered by 3+ golden keyhole scatter symbols. With 4 or 5 scatters you instantly collect an additional 1,000 or 10,000 coins respectively. The feature can also be triggered when you collect five shards of the same colour in the Warehouse Bonus Game.
During the free spins, you can collect diamonds, and if you manage to collect 5 of the same colour, then you unlock the progressive jackpot that corresponds to that specific diamond. Harder to trigger than the Bonus Feature, we still found triggering the free spins possible with some satisfying results.
Putting the pieces together
Holmes and the Stolen Stones slot was released back in 2015 but only recently became available in South Africa. Even if you’re not a fan, this five reel and 20 fixed paylines slot offer five compelling reasons, in the form of the local progressive jackpots, to play.
Also, consider that the volatility is quite low and the RTP is quite high at 96.8%. Finally, the mystery-themed slot follows you wherever you have a wifi connection, as it is supported on Android, iOS and Windows Phone.
