One Mystery symbol may land on the reels in the main game or in Free Spins. When this Mystery symbol lands outside the Crime Zone, it reveals a random symbol from the Paytable. When it lands inside the Crime Zone pattern, the Mystery symbol clones itself throughout all the spots of the pattern, revealing a random symbol of the Paytable, and making thus way for bigger wins.

A winning bet way starts an Avalanche, and the symbols in a winning combination are removed from the reels. More symbols fall then into the just emptied spots, making way for possible new bet ways. In Free Spins, the winnings obtained during Avalanches are multiplied by the Multiplier.

This red pattern of hotspots is activated on every spin. With an initial size of 3 spots on the reels, it increases to 4 and 5 when specific clues from the Clue List are activated. Each winning symbol inside the Crime Zone activates an item from the Clue List. The Clue List is a meter that shows the progression of the game towards Free Spins. When 3-6 clues are activated, the Crime Zone expands to 4 spots. When 7 or more clues get activated, the Crime Zone expands to 5 spots. Free Spins are awarded when 13 clues have been activated.

In Free Spins mode the Crime Zone covers 5 spots and it's active throughout Free Spins. It has the same pattern that activated Free Spins, though it may randomly change position on the reels. The play area displays a City Chase map, which is a meter that shows the positions in which the Multiplier progresses and the Extra Free Spins are awarded. Symbols in the Crime Zone pattern that are part of a winning bet way unlock the same amount of locations on this City Chase map. Every time the car reaches 13 locations, a marker shows that 2 Extra Free Spins are awarded. A Multiplier starts at the value of x1 and grows in increments of 1 every 7 locations; meaning, when reaching the 7th location, wins are multiplied x2 from the next spin. When reaching the final location on the City Chase map, the case is closed, the Multiplier stops at x10, and the game awards the last 3 Extra free spins.
