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.

Bonus mechanics

Bonus is triggered by accumulating buffalo heads on a counter visible above the 5th reel.
Counter starts at 100 after every reset, and the bonus must hit by 1800.
Buffalo heads accrue at approximately 1.7 per spin on average.
When the bonus hits, it is either Hold & Spin or 8 Free Games.

Hold & Spin vs Free Games

Hold & Spin pays more consistently, but is still volatile.
Free Games is feast-or-famine — usually minimal unless you get retriggers.
Retriggering to 100+ free games is possible and can make the Free Games version very profitable.
In Hold & Spin, you need 20 buffalo symbols to fill the board for the Grand jackpot. The board frequently shows 19 before the bonus ends — the Grand is rare and should not factor into play decisions.

Threshold & AP consensus

There is no AP consensus on the exact threshold — estimates range from 1,350+ to 1,700+ depending on who you ask.
Run the Slots data indicates 1,610 is when the game becomes statistically +EV.
Even at high counter values, the bonus can lose money — finding the counter at 1,743 and still losing is possible.

Variance warning

Notorious for extreme variance within the AP community.
Even playable counters come with significant bankroll swings.
Play only if you can absorb the volatility.
