Must-hit-by
Must-hit-by jackpots: how the guaranteed meter works
The short answer
A must-hit-by progressive sets a public ceiling — 'must hit by $5,000' — and the machine guarantees the jackpot pays at or before that value, usually on a random trigger somewhere between the seed and the cap. The closer the meter gets to the ceiling, the more of the game's expected value sits in the unpaid progressive, which is why experienced players track these banks specifically when meters run high.

Ordinary progressives can run forever — the trigger might never fire tonight. A must-hit-by game makes a different promise: printed right on the machine is a ceiling, and the jackpot will pay before the meter crosses it. That guarantee changes both the psychology and the arithmetic of watching the number climb.
How the mechanism works
- A slice of each wager feeds the meter, exactly like an ordinary progressive.
- Somewhere between the seed and the published ceiling sits a hidden trigger point; when the meter reaches it, the game awards the jackpot.
- The trigger point is itself randomized per cycle — you cannot compute the exact remaining distance, only the ceiling.
- After the hit, the meter resets to its seed value and a new trigger point is set for the next cycle.
Why high meters attract attention
As the meter approaches the ceiling, the unpaid jackpot becomes a bigger share of the game's total return — money that must come out, soon, to someone on that bank. That is the entire basis of 'advantage play' on must-hit machines: a bank showing $4,800 of a $5,000 cap carries more deferred value than one at seed. The edge is real but limited — you still need the triggering wager, the base game still drains your stake while you wait, and a casino full of watchers means you may not be the one feeding the meter when it hits.
Illustrative example
| Property | Standard progressive | Must-hit-by |
|---|---|---|
| Trigger | Specific symbol result or random award | Random point between seed and ceiling |
| Upper bound | None — grows until hit | Published cap it cannot pass unpaid |
| Information to player | Current meter only | Meter plus the ceiling — a usable signal |
| Crowding | Steady | Intensifies as the meter nears the cap |
The underlying machinery is the same as any progressive — seed, increment and trigger — and the same session variables apply: what players actually control and how denomination changes the math.
