Bonuses and Free Spins
Re-Spins: Landing 2 scatter symbols on the reels awards 1 re-spin.
Case of Riches Bonus Feature: Landing 3 scatters anywhere on the reels starts the bonus board game, where you must solve the crime.
The board surrounds the reels and gives you 4 dice rolls to move across the ‘?’ clue spaces. Each clue adds points to the ‘clue point meter’ based on its difficulty. Solve the case to activate ‘Mega Spin’; otherwise, the ‘Clue Point Meter’ feature is triggered.
Clue Point Meter: If the dice rolls do not solve the case during the ‘Case of Riches Bonus Feature’, the clue point meter activates. Part of the round meter is ‘blue’ and the rest ‘brown’. The meter spins; landing in the blue area solves the case and activates ‘Mega Spin’.
Mega Spin: A Mega Spin turns the middle reel wild. 3 wild symbols with a 3x multiplier then help create higher-value wins.
