She was recognized for creating her own video game called “Flappy Unicorn.”

“We had this program…that kind of helped me with math because we discussed X axis and Y axis,” she said.

For her achievement, she was one of a handful of students invited to participate in the ceremony at the White House.

Wanda Berrios, Suncar’s mother, said she was “so proud of her (daughter).”
