In an electronic gaming device, an instance of a process uses a set of reels. A determination is made regarding whether or not a result satisfies a trigger condition for a special mode. Responsive to the special mode being triggered, the process is adjusted so that a final outcome of the instance necessarily satisfies a threshold condition. For example, the set of reels is changed by, for at least one of the reels, swapping or modifying the reel strip for the reel to include a higher concentration of target symbol instances, while also increasing a count of instances of symbols enclosed in a reel area. Graphical elements associated with the process can be changed accordingly. The final outcome is determined according to the adjusted process, and indicators of the instance and final outcome can be displayed using the graphical elements for the adjusted process.
