PlayGo has introduced a Go Course that uses short, interactive lessons and game-like features similar to those used by the language-learning platform Duolingo. Designed for people with no prior knowledge of Go, the course begins with placing stones and covers liberties, capturing, and scoring. Lessons take a few minutes and feature characters that guide users through placing stones and answering questions, with immediate feedback. The first few lessons are available without registration. A free account allows users to save their progress. The course is available at playgo.gg.
