Book of Gold centers its gameplay on free games with a randomly selected expanding symbol, creating a bonus where that symbol can fill reels and pay without needing to start on the first reel. In the base game, expanding Wilds cover entire reels before wins are counted, while the Extra Bet adds two special expansion symbols and can place Wilds on at least two different reels in the same spin. It plays as a 5x3 slot with 10 fixed paylines, frequent full-reel transformations, retriggers up to 50 free games, and a maximum win of 2,000x.
