Legends of Chima's video game branch actually comprises three games. Lego Legends of Chima: Speedorz is a "racing mini-game" that will be available today on Lego.com and tomorrow on iOS. Lego Legends of Chima: Laval's Journey, coming to 3DS and Vita in the summer and DS in the fall, is an "amazing adventure" starring the warrior Laval, who is basically Lion-O from the Thundercats.
Lego Legends of Chima Online is the most ambitious of the three games, a free-to-play "online world" from WB Montreal that lets players build weapons and structures, and interact with the Chima characters in missions. It's due this fall.
