Mathematically speaking, the probability of winning the Euromillions Hotpicks jackpot of a whole million is higher than the Thunderball jackpot of only half a million.
Here's how:
The odds of winning the Euromillions HotPicks jackpot, which involves picking and matching all five numbers, are 1 in 2,118,760. In contrast, the odds of winning the Thunderball jackpot, where you need to match all five main numbers plus the Thunderball, are 1 in 8,060,598.
Thus, while both games offer significant jackpots, your chances of winning the Euromillions HotPicks jackpot are substantially better than those of winning the Thunderball jackpot, being approximately 3.8 times more likely.
