What is a Progressive Jackpot?
A progressive jackpot is a prize pool that grows over time as players wager money on the game. Each bet contributes a small percentage (typically 0.5–3%) to the jackpot pool. The jackpot keeps growing until one lucky player triggers the win condition — which can result in life-changing payouts of millions of dollars.
How Progressive Jackpots Work
- Seed amount: The jackpot starts at a minimum guaranteed amount (e.g. $1,000,000).
- Contribution rate: Each spin contributes a fraction to the pool.
- Network jackpots: Many jackpots span thousands of casinos simultaneously — all players feed the same pool.
- Trigger mechanism: Random trigger (any spin can win) OR bonus game (must reach a special screen).
Types of Progressive Jackpots
- Standalone: Single machine only — smaller but hits more often.
- Local network: Linked across one casino — medium size.
- Wide-area network: Linked across multiple casinos — multi-million prizes (e.g. Mega Moolah).
- Daily jackpots: Must hit by end of day — smaller but guaranteed frequent wins.

RTP and Odds
Progressive jackpot slots have lower base game RTPs (85–95%) because a portion goes to the jackpot pool. Your chance of hitting the top prize in any single spin is typically 1-in-50-million or lower. However, the expected value can turn positive when jackpots reach very high amounts — this is called "jackpot hunting."
Jackpot Hunting Strategy
Track progressive jackpots across networks. When a jackpot exceeds its typical hit point significantly (e.g. Mega Moolah averages $5M at win time), the expected value of each spin increases. Some players specifically target must-hit-by jackpots near their ceiling for better odds.
