Jackpot tiers in slots
Jackpot tiers are the separate prize levels inside one jackpot feature, usually named Mini, Minor, Major and Grand (or Mega), with each step up paying more and landing less often. Instead of a single top prize, the game runs several pots or fixed awards side by side. The names are labels rather than a standard, so the values, odds and trigger rules sit in each game’s own help screen.
How jackpot tiers are funded and reset
On a progressive tier, a small slice of every qualifying stake feeds the pot, and that slice comes out of the game’s RTP rather than on top of it. When a tier is won, only that tier drops back to its seed value, which is the preset amount it restarts from; the other tiers keep climbing.
Mega Moolah is the usual example, with four tiers that, according to published game guides, seed at roughly €10, €100, €10,000 and €1,000,000.
Contribution rates are set by the studio or network and are not always disclosed, so any single percentage quoted for the whole industry should be treated with caution.
Where players meet jackpot tiers
Players see the tiers as a panel of counters above the reels. A figure that rises live points to a progressive pot, while a figure that changes only when the stake changes is a fixed multiple of the bet.
Triggers vary by game and include random drops, bonus wheels and symbol collection.
Fixed tiers versus progressive tiers
Many games mix the two kinds, often keeping the Mini and Minor fixed while the upper tiers grow.
Fixed tier | Progressive tier |
|---|---|
| Pays a set multiple of the stake | Pays whatever the pot holds when won |
| Value known before the spin | Value moves with network activity |
| Never grows beyond its multiple | Can reach seven figures on large networks |
| No reset after a win | Resets to its seed after a win |
Common myths about jackpot tiers
The tier most often confused with the whole jackpot is the top one. A headline Mega figure says nothing about how often the Mini pays, and each tier has its own odds.
A high counter does not make a tier due. On randomly triggered pots each spin is independent, although must-drop designs, which pay before a stated ceiling, are a genuine exception worth reading in the rules.
One session proves nothing either way.
