Rockstar Games is rumored to launch a brand new gambling-themed update called High Roller DLC that would be coming to GTA Online and GTA 5 later this month.

High Roller DLC will be available for the Xbox 360 and the PS3, the update allowing players finally play lottery tickets online.

In addition, according to DomisLive (a Youtube host), an insider named St3v3Hacker revealed to him that he discovered horse race betting, and brand new casino games in the source code of the game, possibly hinting the long-awaited online bank heist missions might finally be available soon.

In addition, DomisLive also gave his opinion regarding a new leaked photo of GTA 5 protagonist Michael De Santa talking on the phone in the dark that was recently available on Reddit showing a post on Xbox.com when it revealed information regarding the upcoming High Roller DLC.  

"This image is fake," said DomisLive regarding the aforementioned leaked photo of Michael. "You may have also seen it on YouTube, Reddit, or on GTA forums. This image is not legit guys. Now I'm not saying that the new casino DLC is not going to be called the High Roller update. I'm not saying that. That is a possibility."

Nevertheless, DomisLive still believes that believes High Roller downloadable content is accurate, because his well-known insider [St3v3Hacker] has been very reliable in the past. 

Previously, St3v3Hacker has discovered many items in the source code before they released by Rockstar Games months in advance including golden paint job, brown tire smoke and musical horns.

The High Roller DLC is rumored to be available on July 29, according to Xbox.com.

Rockstar Games released the popular game GTA 5 on the PS3 and Xbox 360 in US stores on September 17, 2013; while GTA Online was released on October 1, 2013.

The newest port of GTA 5 will arrive in stores for the PC, PS4 and Xbox One in Fall 2014.
