Holmes and the Stolen Stones slot machine

This online slot is not the first one based on the adventures of Sherlock Holmes, but there is always room for another one, especially if there is a progressive jackpot. Holmes and the Stolen Stones is developed by Yggdrasil Gaming and has the opportunity to earn big money with bonus features.

Holmes and the Stolen Stones has five reels with three rows and twenty fixed paylines. There is an appropriately themed Victorian soundtrack to the game, and the scene behind the reels suggests a dark London alley and locked doors.

Four high-value symbols of Holmes, Dr. Watson, a bound book, and a magnifying glass, while lower values are card suit icons - spades, hearts, diamonds, and clubs.

There is no wild symbol in the slot, but there are two bonus symbols: a blue 'bonus' keyhole and a golden 'Free Spins' keyhole.

There are two ways to trigger free spins:

• Landing three or more scatter free spins symbols.
• Collect five shards to fill one meter above the reels.

The bonus game is triggered when three or more blue keyhole scatter symbols land anywhere on the reels, and you will be moved to a warehouse containing a large stock of boxes. All you have to do is pick them until you find a bomb that ends everything. You can find:

• Cash prizes
• Diamond shards that are transferred to the main game when the bonus ends.

Holmes and the Stolen Stones uses a pleasing graphic style and sound effects that complement the theme very well. It seems very easy to trigger the various features, which always bring a plus to the player, and there is a good return rate of 96.80%.
