In this guide
“Jackpot slot” covers three quite different designs. Knowing which one you are playing explains the size of the prize, the likely RTP and how often it can be won.
Fixed jackpots
A fixed jackpot is a top prize that does not grow — for example 1 000× your stake. It is part of the normal paytable and counted in the slot’s RTP, so the base game is generally fairer to the player than a progressive slot at the same return figure.
Local progressive jackpots
A local progressive grows from a small slice of every bet on that one game at that one casino. The pot is usually modest, resets after each win and may be relatively frequent. It is useful if you want a jackpot chance without relying on a huge network.
Network progressive jackpots
A network jackpot pools a share of bets from many casinos running the same game. Pots reach large sums because millions of spins feed them, but wins are rare. A well-known example is Microgaming’s Mega Moolah, which has four levels — Mini, Minor, Major and Mega — each with its own meter and a different chance of dropping.
| Type | Funded by | Typical size | Frequency |
|---|---|---|---|
| Fixed | Built into the paytable | Set multiple of stake | Rare to moderate |
| Local progressive | One game, one casino | Small to medium | Moderate |
| Network progressive | Many casinos | Large to very large | Very rare |
The trade-off: a smaller base game
A portion of each bet goes into the progressive pot, so the rest of the game — the part that pays most spins — returns less than the same slot without a jackpot. The advertised RTP often includes the jackpot contribution, which you can only collect by hitting it. That is why a progressive slot can feel tight between wins.
Before you play
- Check the minimum bet that qualifies for the top prize; some jackpots need the maximum stake.
- Check whether the game is excluded from bonus wagering, as is common.
- Read how winnings are paid: some very large jackpots are paid in instalments.
- Budget as you would for entertainment: treat a jackpot as a chance, not a plan.
