The board game will surround the reels and you get 4 rolls of the dice to traverse the ‘?’ spots which are clues.

Clue Point Meter: The clue point meter will trigger if your dice rolls do not solve the case in the ‘Case of Riches Bonus Feature’. A portion of this round meter will be ‘blue’ and the other portion ‘brown’. The meter will spin, and if you hit the blue area, then you solve the case and the ‘Mega Spin’ feature will activate.

Mega Spin: When you win the Mega Spin, the middle reel will become a wild reel. 3 wild symbols with a 3x multiplier will help you land big wins!
