Part of IGT’s legendary MegaJackpots network, these slots are linked across multiple casinos, creating prize pools that frequently reach into the millions. Its ubiquity and proven track record make it a go-to choice for jackpot hunters. A jackpot can be triggered at any moment, whether it has just reset to its seed value or has climbed to a record-breaking amount. While the prizes are typically smaller than network-wide progressives, the certainty of a drop adds excitement and reliability that many players value. These jackpots often appeal to players who prefer consistent rewards over chasing rare, life-changing payouts.
What Are Online Casino Jackpots
Lower-tier jackpots (Major, Minor, Mini) hit far more frequently — typically multiple times per week across the whole network. Daily-drop and Drops & Wins promotions are typically available alongside any UK casino bonus, but the network progressives like Mega casino unionjackpots Moolah are often excluded. Top prizes are smaller than network progressives (typically £1,000–£100,000) but hits are far more frequent. Examples include Pragmatic Play’s Drops & Wins, Red Tiger Daily Drops and Microgaming’s Daily Drops Jackpot. Jon Heywood won £19.4m on Mega Moolah at a 25p stake. Mega Moolah, Mega Fortune, Hall of Gods, Age of the Gods and most other modern progressive jackpots award the jackpot regardless of stake, as long as you’re playing at the eligible minimum (usually 20p–25p). For most players the answer is “both” — small-stake spins on Mega Moolah for the jackpot upside, regular play on a Pragmatic slot like Gates of Olympus or Sweet Bonanza for the daily-drop eligibility.
