The Bézier Game is a free browser game that teaches you to draw clean vector paths. You trace progressively harder shapes — letters, animals, objects — with the pen tool, scored on how few anchor points you use and how well your curves match. It's a surprisingly effective way to internalize the muscle memory designers and illustrators rely on every day in Illustrator, Figma, or Inkscape.

Made by Mark MacKay as part of his Method of Action series (alongside Kern Type, Color, and Shape Type), it has been recommended for years on design school syllabi and Twitter as the quickest way to actually understand Bézier curves rather than just struggle with them.
