Abstract
Innovations in user interface (“UI”) features of electronic gaming machines (“EGMs”) are described. For example, control logic controls the UI of an EGM according to an iterative re-spin process, which uses reels and a reel area on a display screen of the EGM. In a given iteration of the re-spin process, the control logic identifies any locked reels. The control logic spins any unlocked reels for the given iteration on the display screen while holding locked reels in place. The control logic evaluates a condition that depends on whether the reel area encloses a special symbol stack for at least one unlocked, spun reel. If the condition is satisfied, the control logic continues the re-spin process. Upon exit from the re-spin process, the control logic determines a count of special symbol stacks in the reel area, determines an outcome of the re-spin process, and outputs an indication of the outcome.
