Book of Chickens Slot by Genii

A Book of Dead clone shrunk down to a 3x3 cabinet. Five fixed lines run across nine positions, which keeps the base game tight and fast, and the golden Book of Chickens does the usual double job. It pays as the bonus scatter, and outside the bonus it stands in for the chickens symbol on any line, the top-paying icon in the set.

Three books anywhere award five free spins, and the round runs on the classic expanding-symbol rule. At the start a single symbol is picked at random and turned golden. Any time that golden symbol lands on a reel during the round, it stretches to fill all three positions on that reel after the line wins resolve, so one well-placed symbol can paint the whole grid. One wrinkle to watch: if the chickens or the book itself gets chosen as the golden symbol, the book stops substituting for chickens for the rest of that round. Land three more books mid-bonus and the five spins retrigger.

The base game has its own trick on top. After any spin, a Spin Streak respin can fire at random. It grabs one symbol type already on the reels, locks every copy of it in place, then respins the rest, locking more of the same type each time until a paying combination forms. It won't interrupt a spin that's about to trigger the bonus. There's also a Bonus dial ticking away bottom-right, but it's purely decorative, a running tally of bonus frequency that has zero say in when the free spins actually land. Don't read anything into it. The BonusGO button skips the wait and buys you straight into the five free spins.

The whole thing is dressed as a sunny cartoon farmyard. The reels sit in a wooden crate trimmed with hay, set against a red barn, golden wheat, a tomato patch and a sprawling sunflower field with pumpkins piled in the foreground. Symbols are friendly farm produce and animals: carrots, onions, cabbages, tomatoes, a sly fox, a dog, and three wide-eyed chickens packed into one tile. A lighthearted parody of the Genii book formula, leaning on the same expanding-symbol bonus everyone knows, just with vegetables instead of pharaohs.
