A winning combination results in the Reactions feature being activated. The winning symbols are blasted off the reels, and fresh ones appear to take their place. The responses always continue as long as a new winner is established. This is also known as Cascading Wins or Tumbles, and it can be found in most Megaways games.
The symbols of the winning combination vanish after each win, and new ones take their place. This keeps happening as long as you keep getting victories.
