Tetricide (BRK)

Tetricide, from ÆNIGMA Fonts, is a free maze-pattern display font with a severe, architectural mood. The letters are built from squared paths and right-angle turns that echo Greek key ornament, so the font feels less drawn than carved into a rigid grid.

That makes it a strong free font for posters, game logos, sci-fi title cards, zine covers, and short branding where a single word needs a coded, labyrinthine edge. It also fits monograms and initials especially well, because the repeated turns and boxed-in spaces give even a brief setting the feeling of an emblem or puzzle.
