The EP has sold 106,594 copies in South Korea.

Psy 6 (Six Rules), Part 1 was released in a tin that had a fishbowl-like appearance.

The whole ensemble is packaged in a white box printed with information.

In 2015, Psy revealed in his press interview for his 7th full length album that Part 2 was skipped due to his wishes to vent from the popularity of "Gangnam Style" and start anew with the lucky number 7 because he needed more studio albums rather than EPs, considering his lower numbers of full length albums in his career, and the long wait of three years and five months between part 1 and his next project.

South Korean recording artist Roy Kim covered "Blue/Tree Frog" on the eleventh episode of Mnet's talent competition series Superstar K4, where he was crowned the final winner of the show.
