Monkey Business Slot review

Monkey Business is Terminal Games' newest high-volatility release, landing on Stake on 24 July 2026 with a pirate-and-jungle theme built around a very literal cast of scheming monkeys. The 5x5 grid runs on 19 fixed paylines, and the presentation leans into a grimy, castaway camp look — rusted anchors, leaking toxic barrels, and tribal war drums standing in for the usual polished fruit-machine icons.

The game's identity comes from its Monkey wild, which substitutes for paying symbols anywhere it lands and grows more dangerous the longer it survives. Each Monkey collects Banana symbols to build a personal multiplier, and once that multiplier clears certain thresholds, the symbol itself expands to cover more of the grid. It's a mechanic that rewards patience as much as luck, and it's what puts a 50,000x max win within reach once the bonus rounds get going.

Betting Options and Bonus Features

Monkey Business runs at a 96.01% RTP with high volatility, and the swings match what that combination usually promises, a 50,000x max win puts it in top-tier payout territory. The paytable is straightforward: a growling chainsaw pays best among the standard symbols, followed by a toxic barrel and a carved tribal mask, with an anchor, a rusted hook, and the usual card royals filling out the lower end.

The real engine of the game is the Monkey wild. Monkeys substitute for any paying symbol and actively hunt Banana icons to build their own multiplier — starting small, then expanding into a 2x2 symbol once the multiplier clears 20x, and a full 3x3 once it reaches 75x. Land more than one Monkey on a winning line and their multipliers are added together before the line win is calculated, which is how a handful of bananas can turn a modest hit into something considerably bigger.

Bonus symbols control entry into the feature round, and which version triggers depends on how many land: 

• 3 brings the standard Bonus (eight spins where Monkeys collect Bananas from scratch each round), 
• 4 upgrades to the Super Bonus (eight spins where Monkeys stay on the grid and keep whatever multiplier they've already built), 
• 5 unlocks the Epic Bonus, the game's most generous tier. Extra Bonus symbols landing mid-feature extend the round with additional spins, giving Monkeys more time to stack multipliers before it ends.

Bonus Buy Options

Terminal Games also built in 5 optional modes that sit alongside the base game rather than replacing it:

Roshtein’s Take

Terminal Games is still a young studio, but Monkey Business doesn't play like an early swing — it plays like a developer who already knows what makes a bonus round worth chasing. What catches my attention isn't just the 50,000x max win, it's the Monkey mechanic itself: watching a multiplier grow from a single Banana into a full 3x3 wild is exactly the kind of moment I want to catch live. I'll probably run the Bonus buy first to get a feel for how often those multipliers actually stack before I risk anything on Max or Zero. If this is what a young studio is putting out already, I'm curious to see where they take things next.
