221B Baker Street

How to play

Like other slots, the 221B Baker Street offers the basic gameplay of landing winning combinations and getting wins. Even its format is basic among modern slots – five reels, three rows, and 20 paylines. The paylines are not fixed, so before you enjoy the gameplay, you have to select how many lines you wish to have in each round and your total bet.

You can pick your number of paylines from among one, five, 10, 15, and 20 lines on the reels. When you land winning combinations on these lines, they should be from left to right starting with the first reel. The betting range of the slot is gotten by multiplying the number of paylines by the bet per line. You can choose between 0.01 and two.

This sets your total betting range to be between €0.01 and €40, making the game accessible to mostly lower budget players. If you’re playing on the go, select the autoplay option and choose how many times you want the reels to spin.

Symbols and payouts

When you land two or more matching symbols on any of the 20 paylines, you will get some top rewards. The slot features special symbols that unlock bonuses and standard symbols with payouts. The special symbols include Sherlock, which is the wild, and the Big Ben bonus symbol. There are also two scatters, which are Moriarty and the silhouette of a duel.

The wild is the highest paying symbol, offering players 10,000x, 1,000x, 100x, and 10x your bet per line for landing five, four, three, and two symbols across the reel. The Moriarty scatter will give you a reward of 2,000x, 400x, 100x, and 20x your bet per line.

Next on the reels is the pistol with a reward of 600x, 120x, 20x, and 5x your bet per line when you hit five, four, three, and two symbols on any of the pay-lines. Then, the red poison vial offers 500x, 100x, 20x, and 3x your bet per line.

The magnifying glass symbol will give you 400x, 80x and 20x your bet per payline when you land five, four, and three symbols on the reels. Then, A and K offer 250x, 50x, and 10x, while Q and J provide 100x, 20x, and 5x, when you land five, four, and three symbols on a payline.

Best 221B Baker Street bonus features

There are also 221B Baker Street bonus features you can land as you play this game. The Sherlock wild is one of them, and it can stand-in for other symbols on the reels to give out the highest win on a payline, except the two scatters.

Although there are two scatters, the Moriarty symbol does not unlock any bonuses. But, the duel symbol does. It only appears on the second, third, and fourth reels, and landing the symbols on the reels at once will trigger the bonus. It gives you a random number between three and five duels. During the duel games, you can win different cash multipliers on your wins.

To trigger the highlight of the slot, which is the 221B Baker Street free spins round, you need to land the Big Ben symbols. Land three, four, or five Big Ben symbols on the reels and you win two-six, six-14, and 10-20 free spins respectively. You also get multipliers on your wins between 1x and 5x. Plus, the free spins round can be retriggered.

After every win, you have the chance to gamble your winnings and double them. Or, you can decide to collect your winnings and keep on playing.

RTP & volatility

The 221B Baker Street RTP is set at 96%, which is right on the mark of the average level. It is a medium volatility slot, so players can look forward to landing average-sized and consistent wins.
