Comparing Progressive Jackpots and Static Jackpots
There are two main types of jackpot slots: static jackpots and progressive jackpots. Static jackpots are internal prizes only available within a specific game. They payout reasonably frequently and are usually expressed as a multiplier of your base bet.
Progressive jackpots, on the other hand, grow from a portion of wagers across all games linked to the specific jackpot. They are uncapped and continue to rise with every bet until randomly triggered by one lucky player, at which point they reset to a fixed starting seed.
| Feature | Static Jackpot Slots | Progressive Jackpot Slots |
|---|---|---|
| Jackpot prize value | Fixed value jackpots are paid as multipliers of your base bet | Grows over time with player contributions |
| Win potential | Typically capped at around 10,000x max | Unlimited (can reach millions) |
| Payout Frequency | Common within gameplay | Rare and random |
| Volatility | Typically low to medium | Can vary from low to very high |
| Jackpot Trigger | Usually through a bonus feature like Hold and Win or Cash Collect | Random, often with specific bonus symbols |
