Book of Rampage Features
The book
The book substitutes for every symbol and pays as a scatter anywhere: 2×, 25× or 250× the bet for three, four or five. Three or more start 10 free spins, and more books during the round add spins.
Wheel and expanding symbol
When free spins start, a wheel picks one symbol to expand for the whole round. After each spin it expands to cover its reels whenever that creates a win, and pays on all lines even when its reels aren't adjacent.
RTP, maximum win and buy
The demo is set to 95% RTP, caps wins at 5,000× the bet and lists a free spins buy at 104× the bet. Compare Book of Medusa, which uses the same wheel.
