Progressive Jackpots Explained: An Operator’s Guide
A plain-English guide to how progressive jackpots work — pools, levels, contribution, mystery vs must-win, and how they are linked and displayed across a casino or arcade floor.
If you are new to running jackpots, the vocabulary can get in the way of a simple idea: a small slice of play accumulates into a pool, and that pool pays out as a prize. Everything else is detail on top of that. Here is the operator’s version.
The pool
A jackpot pool is money that accumulates from play and is paid out when the jackpot hits. A progressive pool grows with play (visibly, on a meter); a fixed prize does not. The growing meter is what makes progressives compelling — players watch the number climb.
Levels (tiers)
A jackpot can have one level or several — Prosperity supports 1 to 10. Common naming runs Mini, Minor, Major, Grand, Mega, but the names are yours to set. Lower tiers hit often for small amounts; higher tiers hit rarely for large amounts. More tiers means more on-screen movement and more frequent wins.
Contribution
Contribution is the percentage of each bet that feeds the pool. It is the lever that funds the jackpot and the one that comes out of theoretical hold, so it is set deliberately per level. See the right jackpot strategy for how to choose it.
Mystery vs must-win
- Mystery jackpot — hits at a random value within a range; the player never knows exactly when, which keeps every spin live.
- Must-win-before — a ceiling that guarantees a tier pays before a set value, giving you a predictable, advertisable event.
Linking and scope
A jackpot can be standalone (one bank) or share a tier floor-wide (many machines linked into one pool). On a real floor the best layout is usually a banked hybrid — a jackpot per bank so players move between them, plus a single top tier linked floor-wide. A lone floor-wide jackpot tends to become wallpaper, and achievable, frequent wins beat one rarely-dropping number. Covered in floor-wide, standalone or banked.
Display
Finally, the jackpot has to be seen. It displays on an overhead bank sign, a cabinet topper, or the cabinet’s top-box monitor — each with a different reach, covered in jackpot signage options.

Frequently asked questions
How does a progressive jackpot work?+
A small percentage of each bet (the contribution) feeds a pool that grows visibly on a meter. When the jackpot hits — at a random value (mystery) or before a ceiling (must-win) — the pool pays out and resets. Jackpots can have multiple levels and can link many machines into one shared pool.
What is a mystery jackpot?+
A mystery jackpot hits at a random value within a configured range, so players never know exactly when it will drop. This keeps every spin live, versus a must-win jackpot that guarantees a payout before a set ceiling.
What does "must win before" mean?+
It is a ceiling on a jackpot level that guarantees the tier pays out before reaching that value — for example "must win before €10,000". It makes the event predictable and advertisable.
