Blek

Blek is a 2013 puzzle video game for iOS and Android where you draw a snakelike black line that repeats its shape and velocity across the screen. The line erases colored dots while avoiding black obstacles, turning simple gestures into a rhythmic challenge. Its minimalist design, ambient soundtrack, and excerpts of poet Erin Gee create a meditative experience inspired by Japanese calligraphy and the Bauhaus. Developed by the Kunabi Brother team, Blek earned a 2014 Apple Design Award and sold over one million copies.
