A heavy, rounded-rectangle sans with squared-off curves and softly radiused corners throughout. Strokes stay consistently thick, producing compact internal counters and a strong, poster-like silhouette. Many joins and terminals resolve into flat, horizontal cuts, giving the face a modular, superelliptical feel; curves are more squarish than circular, especially in bowls and shoulders. Spacing and widths vary by glyph, but the overall rhythm is dense and stable, with short ascenders/descenders and a prominent x-height that keeps lowercase forms stout and highly graphic.
Best suited for headlines, logotypes, and short statements where maximum visual weight and a distinctive geometric voice are desired. It works well on posters, packaging, event titles, and signage that benefits from a retro, arcade-leaning aesthetic. For longer passages, larger sizes and generous line spacing help preserve clarity.
The tone is bold and upbeat, with a distinctly retro-tech and game-like flavor. Its chunky geometry reads as friendly rather than aggressive, evoking toy packaging, arcade graphics, and 1970s–1990s display typography. The compressed counters and rounded corners add warmth while still feeling engineered and punchy.
The design appears intended to deliver an instantly recognizable, high-impact display look built from rounded-rectangular forms. It prioritizes bold silhouettes, tight counters, and a playful industrial geometry to create a memorable, brandable texture.
The design favors strong rectangular silhouettes and notch-like apertures, which increases impact at large sizes but can darken texture in longer text. Numerals and capitals present as particularly block-forward, making the font well suited to big, simple messages where shape recognition comes from overall outline rather than internal detail.
