Symbols forming wins disappear, making way for new symbols to drop in that may form new wins.
The Wild substitutes for all paying symbols and counts as the symbol which forms the longest winning combination on a single win line.
A speedometer with 5 levels is positioned above the reels. Each win increases the speed to the next level, activating a different modifier for the following chain reaction.
The modifiers for each level are as follows:
If the speedometer reaches level 3 or higher in a spin, the round does not end after a non-winning chain reaction. Instead, another chain reaction is triggered at the lower level of the speedometer. The chain reaction is triggered by removing all symbols on the reels except WILDS and FREE SPINS scatters. A non-winning chain reaction at level 2 ends the round.
Landing 3, 4 or 5 FREE SPINS scatters anywhere on the reels triggers 3, 6 or 12 FREE SPINS respectively.
The bonus round is played at the last level of the speedometer, with no royal symbols on the reels and a constant x5 WIN MULTIPLIER.
Landing 3, 4 or 5 FREE SPINS scatters during the bonus round grants a retrigger of 3, 6 or 12 FREE SPINS respectively.
