Who doesn’t love Sherlock Holmes? Everyone knows the World’s Greatest Detective isn’t really Inspector Gadget. It’s Arthur Conan Doyle’s Sherlock Holmes and his good friend Dr Watson. If you somehow manage to land Dr Watson next to Sherlock Holmes then you get an instant bonus called the Sherlock Meets Watson bonus. Getting this scores you an instant payout of 3x your bet and it comes up surprisingly often. Sherlock Mystery is your typical 5-reel, 20 pay-line affair.
