Progressive Jackpots: How They Work and How to Win
Progressive jackpots can grow to millions of pounds from contributions across thousands of players. This guide explains how they are funded, the different types, whether bet size matters, and which jackpot slots have the best odds.
What Is a Progressive Jackpot?
A progressive jackpot is a prize pool that grows over time, fed by a small percentage of every bet placed on the game. Each spin contributes a fraction to the jackpot meter, which continues to rise until one lucky player triggers the win.
Unlike fixed jackpots (where a slot always pays a set maximum win), progressive jackpots have no ceiling. Some have paid out over €20 million from a single spin.
How the Jackpot Builds
Every bet on a progressive jackpot slot contributes a small percentage, typically 1–3% of each wager, to the jackpot pool. This means:
- A €1 bet might contribute €0.02 to the jackpot
- With thousands of players betting simultaneously across a network, the jackpot can grow by thousands of euros per hour
The progressive contribution comes out of the game's total RTP, which is why progressive jackpot slots often have lower base game RTP (sometimes 88–93%) than non jackpot slots.
Types of Progressive Jackpots
Standalone Progressives
The jackpot only accumulates from bets on that single machine at that single casino. Starting values are lower and growth is slower, but the jackpot is not shared across networks.
Local (Casino) Progressives
Contributions come from all players at the same casino playing that game. Larger prize pools than standalone, but limited to one operator's player base.
Wide Area Network (WAN) Progressives
The most common type for major jackpots. Contributions pool across thousands of players at hundreds of casinos worldwide who are playing the same game simultaneously. This creates the massive multi million euro jackpots.
Famous WAN progressive slots include:
- Mega Moolah (Microgaming) : has paid the world record online jackpot of over €22 million
- Major Millions (Microgaming)
- Jackpot Giant (Playtech)
- Age of the Gods series (Playtech)
Must-Drop Jackpots
A variation on standard progressives, must-drop jackpots are guaranteed to pay out before reaching a certain amount or by a set deadline. Variants include:
- Must-drop by value : the jackpot must be won before it reaches €X (e.g., must drop before €50,000)
- Must-drop by time : the jackpot must pay out within a 24 hour window
- Daily drop jackpots : Red Tiger's Daily Jackpots guarantee a prize drops every day
Must-drop jackpots are particularly popular because players can see exactly when a prize is statistically due, encouraging play as the jackpot approaches its ceiling.
Does Bet Size Affect Jackpot Chances?
This depends on the game:
- Bet linked jackpots: Your chance of winning is proportional to your bet size. Betting €2 gives you double the jackpot chance of betting €1. Mega Moolah works this way.
- Random trigger jackpots: The jackpot can be won on any spin regardless of bet size, but higher bets may still statistically increase your odds of the trigger.
- Must qualify jackpots: Some require a minimum bet to qualify for the top jackpot tier. Read the game rules before betting less than maximum on these.
Progressive Jackpot Strategy: Is There One?
Genuinely, no, progressive jackpots are driven entirely by luck. Many of the biggest jackpot titles appear in our high volatility slots and most popular slots collections. However, practical considerations:
- If maximum bet is required to win, only play at a stake you can sustain long term
- Due to lower base game RTP, jackpot slots drain bankrolls faster during normal play
- Must-drop jackpots approaching their ceiling offer marginally better value than jackpots at their starting value
- Never spend more than you can afford chasing any jackpot, by definition, it is a very low probability event
