The Holmes and the Stolen Stones slots game boasts an auto-play feature that allows players to set the game to automatically spin up to an infinite amount of spins at the chosen coin value amount. Players can set the auto spins to stop on a single win of a specified amount, when their cash balance increases or decreases by a certain amount, or when free spins or a progressive jackpot is won. Check the pay table (the ‘i’ button below the reels) for a complete break-down of symbol payouts and game rules.

Game bonus features

The aim of the Holmes and the Stolen Stones game is to collect shards of diamonds of the same colour (five shards of the same colour form one diamond). Once you have collected five diamonds of the same colour, you will win the respective progressive jackpot (blue, red, yellow, green and purple diamonds).

Bonus symbol: Land three or more bonus symbols (blue and aged key hole) and you will trigger the bonus game. Four bonus symbols will also net you 1,000 coins and five bonus symbols will net you a handy 10,000 coins. There are 18 crates hiding treasures, including bags of coins and shards of diamonds. The shards you manage to collect will be transferred to your collection in the main game (diamond metre is underneath the progressive jackpots). The bonus game will end if you pick a crate with a smoke bomb.

Free spins modes: Land three or more free spins symbols (golden and shiny key hole) to trigger 10 games on the house. Four free spins icons will also net you 1,000 coins and five free spins icons will pay you out 10,000 coins. You can unlock another 10 free spins by collecting five shards of the same colour. Whichever bonus spins mode you are in, all wins are multiplied by three and come with the chance to land full diamonds rather than shards.

All wins pay from left to right, except for free spin symbol and bonus symbol wins, which pay anywhere. Malfunctions during the game void all pays.
