Fortune Mouse Slot by PG Soft

First in PG Soft's Fortune zodiac lineup - Mouse came before Ox, Tiger, Rabbit, Dragon, and the rest. The Chinese legend has the mouse hitching a ride on the ox's back to arrive first in the zodiac race, and the game takes the same shortcut with its design. One feature. That's it. No scatter symbol, no free spins round, no multiplier progression, no buy bonus. The Fortune Mouse Feature triggers randomly during any base spin: three Wilds fill the entire center reel, then reels 1 and 3 respin until they produce a win. Guaranteed payout every time it fires.

The respin loop is what separates this from a standard three-reel. With the middle column locked as all-Wild, the outer reels keep spinning until at least one payline connects across the five lines. If all nine positions end up Wild, that's the 1,000x ceiling. The feature hits about once per 100 spins based on the 1.02% trigger rate, and it accounts for nearly a quarter of the total return - the base game handles the other three-quarters through conventional left-to-right payline wins. Fortune Rabbit and the later zodiac entries added Prize symbols, asymmetric grids, collection mechanics. This one predates all of that complexity. Three reels, one feature, a golden mouse on red silk.
