Named after his 10-year-old daughter, Karma Bridges, Karmasworld.com is an interactive kids' site that features stories, original pop songs with educational lyrics, and games like 'Karma's Crosswords' and 'Scrambled Continents', reports AllHipHop.
The rapper-actor said that he wants the website to be both educational and fun.
"The site touches on subjects like the rewards of hard work and importance of learning manners, as well as the idea that doing good deeds for others will bring good into your life - which is the meaning of the word Karma," Ludacris said.
"The music and lyrics, games and stories on the site are all original and were created by me, my daughter and my creative team."
Ludacris, who recently performed at the American Music Awards, can be seen next in the movie New Year's Eve opposite Hilary Swank.
New Year's Eve hits theatres this week on December 8 in the UK and December 9 in the US.
