The present disclosure is directed towards Class II electronic gaming systems and/or machines that present a bingo game outcome (and/or associated bingo game reward) to a player via a spinning reel (and/or slot) game simulation. In some examples, the bingo game outcome may trigger a free spin feature mode comprised of one or more spinning reel game outcomes. During the free spin feature mode, each spinning reel game outcome may be a winning outcome, with an associated spinning reel game reward. The sum of the one or more spinning reel game rewards may be equal to the bingo game reward. In some examples, each spinning reel game reward may include a base reward and a multiplier. In some examples, the multiplier is always one (i.e., 1×) during regular play (i.e., not in free spin feature mode), and one or more (e.g., 1×, 2×, 3×, 4×, 5×, 10×, etc.) during free spin feature mode. The multiplier may be highlighted and/or emphasized when greater than one. The spinning reel game rewards may be presented in increasing order of the base reward.
