What is a Must-Hit-By progressive slot?

A Must-Hit-By (MHB) progressive is a type of slot machine jackpot that is guaranteed to pay out before reaching a specific maximum value. The jackpot meter increases as players wager, and once it nears the ceiling, the probability of it triggering increases significantly. This mechanic gives advantage players an opportunity to identify when the expected value becomes favorable.
