The Washington Metropolitan Area Transit Authority is asking for help cracking a string of games that have been hacked, according to a report by The Washington Times.
The games, some of which have been locked down, are often downloaded by millions of people worldwide.
The Times says the hacks have been in the works for several years.
The MTA says the hack is part of an ongoing initiative to fight online gaming.
The agency did not immediately respond to a request for comment from The Associated Press.
A recent report from the Electronic Frontier Foundation found that gamers are at an increased risk of losing their online gaming accounts.
