LAS VEGAS — The Super Bowl looks like a tossup in this gambling city, where more than $100 million will likely be riding on the game by kickoff.

A flurry of early money on the New England Patriots moved the game to pick `em at most major Las Vegas books Sunday night after the Seattle Seahawks opened by as much as 2.5-point favorites.

Oddsmakers say they don’t expect the line to fluctuate much over the next few weeks, with heavy betting anticipated on both sides.

“You’re not going to see this one bounce around like you did last year,” said Jimmy Vaccaro of the South Point sports book. “Last year the whole world was in love with Denver early .But this game is going to stay right around Seattle a 1-point favorite or pick `em the entire way.”

At the Westgate Las Vegas Superbook, the opening line favoring the Seahawks by 2.5 points moved quickly even before the Patriots-Colts game was over.
