It's always a great idea to watch the jackpots and go after the ones that are getting HUGE. The fact that the jackpots are high does not necessarily mean it is more likely to hit than a lower jackpot game - however if you want to place your chances anywhere you'd want to win the most money. Land based casinos in Las Vegas do occasionally 'force' a jackpot winning when the amount gets to a certain point, but I have not come accross any evidence that the online casino operators do this. But you never know, they might - either way this means the large jackpot play may be your best bet at an online casino for winning HUGE. Good Luck!
