Bonus Rounds & Free Spins

7.7 

Free Spins

When you land 3 Scatter symbols, the bonus game is triggered. It consists of the following parts: Objective, Starting the case, The board and the challenges, Solving the case, and the Second Chance wheel. The main goal of this bonus feature is to collect evidence and help Sherlock solve the case. You will have 4 moves to fill the key points counter. You will roll a dice at the beginning of each turn, and Sherlock will move along the board and stop on Free Spins.

If you collect enough clues to solve the case after the 4 moves, you’ll receive a Mega Spin with 3 reels. The 3rd reel will be filled with Multiplier Wilds. After Mega Spin, the bonus will work again, and you will get asked to solve another case.

But if 4 turns are over and you didn’t score enough clue points, you will be presented with a Clue Wheel. By spinning the Clue Wheel you’ll have another chance to solve the case.

Mystery Bonus

If you land 2 Scatters, you’ll get a second chance Respin to enter the Free Spins bonus round. If the needed 3rd Scatter doesn’t appear, the Mystery Bonus feature is activated.

In the Mystery Bonus, the Scatters expand on their reels. Then, they will reveal a character or a weapon symbol. This can lead to a solid consolation prize.
