[3] After purchasing twin famiclones, Andrew began to compete in tournaments under the name "P1xelAndy", while his brother Michael adopted the name "DogplayingTetris" or simply "Dog".

[3][5] After beating fellow competitor Nenu Kariko,[6] Andrew made it to the final round with his brother Michael, where they competed against each other at their same house due to COVID-19 restrictions.

[3] In the 2021 CTWC, Artiaga placed second in his seed after achieving eleven "maxouts", a point in the game where the score becomes so high it no longer registers correctly on-screen, in his qualifying rounds.

In the 2023 CTWC, Artiaga placed sixth in his qualifying seed but lost in the quarterfinals to Justin Yu (known online as "Fractal161"), who went on to win the championship.
