Code Ninjas opened April 15 in a 2,606-square-foot space in the Castle Hills Village Shops at 2500 King Arthur Blvd., Ste. 122, Lewisville. Code Ninjas offers programs for ages 7-14 to learn coding with math, logic and problem-solving skills within a video game-based curriculum. The center follows a karate theme in which students are referred to as "ninjas," and they earn belt rankings as they progress through the curriculum, learning from their "senseis." 972-410-0231. www.codeninjas.com
