1. A computer system comprising one or more processors and memory readable by the one or more processors, the memory having stored thereon computer-executable instructions for causing the one or more processors, when programmed thereby, to perform operations to control a user interface of an electronic gaming device, the operations comprising:
in a process that uses a set of reels, each of the set of reels having a reel strip:
using one or more index tables to identify symbol positions at which to swap in instances of a target symbol, wherein the symbol positions are identified without using random number generator events;
swapping in the instances of the target symbol; and
after the swapping in the instances of the target symbol, determining spin results for one or more spins of each of the set of reels, respectively, using the reel strips.
