Some Islanders are looking to score on a power play — off the ice. Even financially well-heeled pros have Powerball fever when the prize is $1.5 billion.

John Tavares, in the midst of a six-year contract worth $33 million, planned on picking up his ticket after practice at IceWorks for Wednesday night’s drawing. “I bought one on Saturday,’’ he said. “It keeps going up so you have to.’’

Tavares hasn’t made too many plans for the winnings, but said he would not take early retirement at 25. “Definitely not. I think obviously you’d like to do some good things. I’m sure there would be a lot of giving.’’

Ryan Strome added, “I think we’re pretty fortunate in our [financial] situations right now. I think I would give a lot away to charity. I’d be a little greedy and probably get a couple of toys for myself as well.’’

Coach Jack Capuano, albeit preoccupied in preparing for Thursday’s game with the Rangers, found time to buy a ticket. But he promised, “If do hit it, I will still see you guys [Thursday]. I can’t leave you guys.’’

Brock Nelson said “there’s so many things’’ he would consider buying. “Maybe a house or something like that. Probably in the sun, somewhere warm.’’

Nelson, who scored his first career hat trick Tuesday, was asked what would be tougher, a second consecutive three-goal game or winning Powerball. Before he could answer, Eric Boulton jumped in and said, “Powerball. Hat tricks are easy in this league. If I can get one, anybody can.’’

Melo takes a shot. The Islanders aren’t the only local pro athletes with a case of Powerball fever. The Knicks’ Carmelo Anthony, who has a base salary of more than $24 million this season, said on Monday that he had purchased tickets. Asked what he would do with the money if he wins, Anthony said: “I’m going to share it all.”
