How progressive jackpots work
Progressive jackpots pool a small percentage of every bet from every player on every casino running the game. The pool grows constantly until one lucky spin triggers it — and resets to the seed value. Mega Moolah is the most famous example, with regular eight-figure GBP payouts.
Local pools, like Pragmatic Play's Drops & Wins, are exclusive to Cassoola players. Every spin on a participating slot enters you into daily and monthly prize draws. Winning is random, with no skill or stake threshold beyond the published minimum.
Picking the right jackpot
Standard advice: target jackpots that are above their average payout value. Trackers in the lobby show current pool size, average drop value and time since last drop — useful indicators of when a slot is statistically 'overdue'.
Min/max bets vary widely. Some progressives require the full coin bet to qualify; the lobby flags this clearly. Always check the game info panel before spinning so you know the qualifying stake and the maximum win cap.
