You can pay $25 to enter one of the dozens of football contests around town (where your chances of winning are equal to getting struck by lightning while winning the lottery). Or you can take the skirt off, strap on a helmet and go for the big bucks by entering the legendary Las Vegas Hilton Supercontest. For the last two decades, 350 to 400 serious NFL handicappers have anted up $1,500 for the season-long contest (the gist of the contest: Pick any five NFL games against the spread each week). All entry fees are returned in prize money paid out to the top-20 finishers, with the winner taking a huge chunk of the pie. Last year’s champ hauled in $207,000, while five contestants who tied for 10th each pulled in more than $7,700. An added incentive: The Hilton kicks in $10,000 for an end-of-season contest (the player with the best record over the final three weeks collects the loot) and another $10,000 if the overall champ picks at least 67 percent winners through the season. Now that’s a contest.
