Genii built Monkey Business as a five-reel satire of Wall Street, and the joke lands harder than it should. Picture a city skyline strangled by jungle vines, a gorilla in a tie shuffling papers behind the reels, and bananas literally pinned to the symbol grid like ticker quotes. It's silly. It's also a properly structured 20-line slot with a top symbol paying 5,000 coins for five-of-a-kind, which is no small upside on a $50 max bet.
The setup is classic 5×3 lines play, but the math has personality. Top five symbols (the suited gorilla, the ape on the laptop, the City Chimp characters) pay from just two-of-a-kind, which keeps the dust devils of small wins blowing through the base game. Low-tier symbols still need three matches, so you're not drowning in micropays either. Bet sits between $0.01 and $50, with a 10-tier coins-per-line slider that feels slightly fiddly compared to a clean 5-tier setup. Honestly, the bet menu is the one bit of UI that hasn't aged well.
The Gorilla Stock Broker wild substitutes for everything except the two scatter symbols, with no self-pay and no multiplier. He's pure filler, but on 20 lines that's enough. Three or more Peanut Paypacket scatters trigger Fire the Monkey, a themed bonus paying multiples of the triggering bet (so bet big when you sense it coming, since it's purely proportional). And three or more City Chimps deliver Free Spins on an unusually generous curve: 10 spins for three, 15 for four, and a sharp jump to 30 for five.
That five-scatter doubling is the headline. Most slots scale free spins linearly. Genii made the rare 5-scatter trigger genuinely worth chasing. No multiplier during the round, retriggers allowed, bet locked. Volatility runs high, the RTP sits at the 96% mark, and there's no buy bonus, no jackpot, no ante. Just stock-broker chimps, peanut salaries, and a free-spin spike worth waiting for.
