221B Baker Street Slot Game

221B Baker Street online slot is a literary address that immediately brings to mind a bygone era of smoggy London streets and horse-drawn carriages. It's where the famous detective, Sherlock Holmes, solves murders with his smoking pipe and gun. 

The 221B Baker Street slot game from Merkur stays true to its theme with symbols like a chillum, handgun, wine glass, and pack of cards. These offer lower payouts than the more significant symbols like Sherlock, Dr Watson, and Moriarty. Big Ben is a wild card, as are Sherlock and Dr Watson. Moriarty and the duel symbol are scatter symbols that pay in either direction, but the latter is only available on reels two, three, and four. 

After the duel, you'll be given a prize that you can choose to keep or duel again. If you get three or more Big Ben symbols, you'll unlock free games. Additionally, when you achieve winning lines, you'll see three options at the bottom middle of the screen. You can collect your winnings, take the card gamble, or take the ladder gamble. 

If you choose to collect in this slot, your winnings will be added to your total and you can spin again. If you select the card gamble, you'll see a pack of cards with one face up and you'll have to predict whether the next card will be black or red. You can keep repeating this step up to a maximum of 140 or the currency equivalent. 

If you choose the ladder gamble, you'll see a ladder with multiples of currency doubling at each step. You can keep pressing the gamble button to climb the ladder and win greater rewards up to a maximum of 140. During this extra gameplay, you'll have the option to collect your winnings at any point or collect half. Opting for the second option means that half of the money you win will be deposited in your bank account before you proceed. Join Holmes when you play this slot game at Prime Slots.
