Progressive slots are connected across multiple online casinos through the same software provider, like Microgaming or NetEnt. Every time a player spins the reels on one of these games, a small portion of their bet is added to the progressive jackpot. This pooled system enables the prize to grow rapidly, often across thousands of players simultaneously.
The jackpot amount remains the same across all participating casinos and updates in real-time. That’s how well-known progressive slots like Mega Moolah or Mega Fortune can climb past $15 million before being hit. Once won, the jackpot resets to a base amount and begins growing again with every spin.
