Investigators say a post from the rapper's Twitter account told his more than 580,000 followers to call for an internship, but the number was for the Compton sheriff's station.
Officials said it compromised public safety. Phone lines were jammed for more than two hours, and people with real emergencies couldn't get through.
The Game, whose real name is Jayceon Terrell Taylor, apologized and said it was all a mistake.
"I'm sort of a reckless Tweeter, but I definitely won't have any police-involved Tweets. We not revisiting that because that was just a nightmare," Taylor told Eyewitness News.
The Game admitted the Tweet did come from someone on his team - but not from him.
"I was doing a photo shoot in Koreatown, downtown Los Angeles, and one of my boys picked up my phone and started Tweeting random numbers," he said.
He did take responsibility, saying, "Sometimes, man, it just happens like that, man. You got to fry the bigger fish and in this case, it was me."
"We have to take the responsibility and understand that we are role models and, you know, and not forget that, man, and just represent that well enough to not abuse the power of free speech," he added.
That power now comes with what's available in the social networking world.
Just a few weeks ago, DJ Kascade let his 92,000 Twitter followers know he'd be on Hollywood Boulevard hosting an impromptu block party to promote a movie. Thousands showed up, causing disruptions, violence and arrests.
Law enforcement has identified that, while social media is fun for society, it can be dangerous, too.
"What we're working to do is to understand it better, to get a better grip on it and so we can be more effective to protect the people," Sheriff's Capt. Mike Parker said.
After consulting with the Los Angeles County District Attorney's Office, the Sheriff's Department decided not to press charges, saying the criminal investigation into the matter was closed.
The rapper said he has learned the power of social media from all of this.
"You just got to watch what you Tweet, man, because the social network is a lot bigger and a lot more powerful than I thought it was," the Game said. "I've been doing so much to turn my life around on a positive note, that it was just crazy that something so small could have such a negative effect on myself, my career, my family and my fan base."
He said this incident also made him realize just how loyal his fans are.
The rapper is moving on from the whole "Twittergate" incident. His latest musical release, "The R.E.D. Album," comes out Tuesday. He stressed that the Twitter episode was by no means a publicity stunt.
