Guaranteed Minimum Win is a 'safety net' feature, often found in the free spins bonus of high-volatility slots. If the total winnings at the end of the bonus round are less than a predetermined minimum amount (e.g., 10x the bet), the bonus is retriggered or additional spins are awarded until the minimum amount is reached. The core of this feature is to mitigate the extreme frustration players feel from a 'dud bonus'—a bonus round that ends with little to no winnings after being entered with high expectations.
