Fans of the video game franchise "Grand Theft Auto" were excited to have finally gotten their hands on the much-delayed yet eagerly-awaited DLC pack, "Online Heists." Only weeks after the pack's arrival, Rockstar Games seems to have another trick up its sleeve, at least according to the rumors circulating within the gaming community. 

According to "GTA" observer Funmw2, the upcoming update for "GTA Online" is an entirely new "Casino" DLC, also to be known as the High Roller update. There will be different activities that focus entirely on gambling for this update.

The hardcore "GTA" fan tweets, "Gambling functions like casino, lottery and car betting is R* next project for GTA Online. Some point in the coming months by the looks." 

Rumors of a casino update have already been circulating even before the release of the "Heists" DLC. Several "Grand Theft Auto" players have found a glitch that allowed them to enter the interior of a casino building in the Los Santos area. The building's interiors were bare, but it set tongues wagging and rumors to spread that the developers were already working on a gambling-centered expansion for the game. Funmw2 added to the rumor mill by tweeting that the new update will reveal four new mini-games, coming in the form of blackjack, poker, roulette, and slots. Owing to the vastness of the "Grand Theft Auto" maps, there might be a lottery system and horse betting system set in place, too. 

Before the unexpected delays of the "Heists" DLC, Rockstar Games made it a tradition to come out with one new "GTA V" DLC expansion every month. If this would be the case, hardcore fans are also saying that the new DLC update might come out in April, to coincide with the launching of "Grand Theft Auto V" for Windows PC on April 14.
