You can still collect $200 when you pass “Go,” but not in piles of play money.

In the new version of Monopoly, the game’s classic pastel-colored bills and the designated Banker have been banished, along with other old-fashioned elements, in favor of a computer that runs the game.

Hasbro showed a preview of the new version, called Monopoly Live, at this week’s Toy Fair in New York. It is the classic Monopoly board on the outside, with the familiar railroads like the B.& O. and the development of property. But in the center, instead of dice and Chance and Community Chest cards, an infrared tower with a speaker issues instructions, keeps track of money and makes sure that players adhere to the rules. The all-knowing tower even watches over advancing the proper number of spaces.

Hasbro hopes that the computerized Monopoly will appeal to a generation raised on video games amid a tough market for traditional board games, a category where sales declined 9 percent in 2010, according to the market research firm NPD Group. “How do we give them the video game and the board game with the social experience? That’s where Monopoly Live came in,” said Jane Ritson-Parsons, global brand leader for Monopoly.

With free digital games everywhere, Hasbro is hoping to revive interest among young children and preteenagers in several of its games that cost money. (The new Monopoly, available in the fall, will be about $50.) Battleship will undergo a similar digital upgrade this year, and other Hasbro games will be redesigned for 2012 and 2013, Ms. Ritson-Parsons said.
