Mad Mad Monkey II Slot by Light & Wonder

The cleanest way into the RESPIN bonus here isn't landing six Coins. It's Monkey Luck, a random base-game trigger that fires on spins where nothing else hit. When it does, the Banana Tree meter stacked on the left of the cabinet empties out, dropping up to 6 Coins onto random positions, and the RESPIN feature opens immediately. Every Coin that lands during normal play feeds that meter beforehand, so the Tree is a slow burn that the game can dump on you without warning. The orange grinning monkey swinging on a vine to the right of the reels is the visual cue when it triggers.

Inside the RESPIN round, the reels strip down. Only Coins and Bananas appear, royals and the Monkey Wild are gone. Three respins to start, every new Coin or Banana resets the counter back to three, and the round ends when the counter hits zero or all 20 positions are full. Coins carry fixed bet multipliers (0.4x, 1x, 1.4x, 2x, 2.4x or 5x) or one of two jackpot prints, MINOR at 10x and MAJOR at 25x. The GRAND sits at 250x and only triggers if every position on the grid fills with Coins. Bananas don't stick like Coins do, but each one upgrades all 8 surrounding Coin positions by 0.2x, 0.4x or 1x bet, and every Banana that lands also drops into a separate counter that activates the next phase.

That phase is Monkey Mad, a post-RESPIN bonus that only runs if you collected at least one Banana. Each Banana reveals either a 2x, 3x or 5x multiplier applied to a random existing Coin, or a brand new Coin worth 3x or 5x bet (with MINOR and MAJOR still on the prize pool). New Coins added here don't restart the respins, they just stack onto the final total. Skip the wait via Buy Bonus if you'd rather pay in directly.

The base game uses the Monkey Wild on reels 2, 3 and 4 only, and every line win it contributes to gets doubled. Premium symbols are the jungle cast you'd expect from a sequel to the original Mad Mad Monkey: blue parrot, green snake, red frog, coconut, peanut, all rendered in the same exaggerated cartoon style as the mascot. The cabinet drops the reels into a misty teal rainforest with curling vines and glowing turquoise mid-depth, the bamboo-frame Banana Tree meter pinned to the left and the MINOR/MAJOR/GRAND ladder banners stretched across the top. This is a Light & Wonder release built with Boomerang Gaming Studios, and the Boomerang co-credit sits stamped along the bottom UI in purple. Worth noting the Grand only fires once per round, the MINOR and MAJOR can land repeatedly.
