In White Orchid, the main White Falls Free Spins round is triggered differently. To activate it, you need to land a stack of two, three, or four symbol-high bonus icons on the central reel, which grants you up to 20 free spins. On the other hand, in most other IGT slots, Free Spin rounds are typically triggered by collecting three or more bonus symbols in any position on the grid during the same spin. This unique triggering mechanism makes the Free Spins round in White Orchid stand out from other IGT slot games.
