**DoubleDown Casino’s Three Kings boosts free games bonus rounds by adding a progressive feature**

Three Progressive Free Games meters are displayed to the side of a 4 x 5 reel set (image 1).
Each of the progressive meters may randomly increase as more games are spun. Flames appear within the meters when the number of free games reaches an average. This does not indicate a higher chance of triggering the free games (image 2).
Any three same-colored bonus symbols triggers the Progressive Free Games feature. Green bonus symbols only appear on reels 1-3, red on 2-4, and purple on reels 3-5 (image 3).
Once triggered, a dialogue appears displaying the number of free games won and the additional wild symbols (image 4).
