FAIRBANKS -

The manager of Alaska's largest guessing game, the Nenana Ice Classic, says this year's jackpot is worth more than $363,000.

The jackpot goes to the person who most closely guesses when the ice breaks up on the Tanana River in Nenana, or when the wooden tripod on the ice moves enough to stop a clock it's connected with on the shore.

Game manager Cherrie Forness said Thursday that this year's pot is $363,627.

Last year's breakup was late -- May 20.

In many years, there are multiple winners, but a couple from Kenai pocketed last year's entire $318,500 jackpot.
