Games

Browser games that teach a concrete skill
These are playable web experiments, but they are not throwaway demos. World Map Trainer teaches country shapes, capitals, flags, and global map recall across 233 quiz items. Gefühlsrad Trainer teaches 78 German and English emotion words through a filled emotion wheel. Both save progress locally in the browser, so the practice stays lightweight.
For CIOs, product leaders, and curious builders, the common thread is useful literacy: global operating context, language precision, change communication, and small tools that do one job clearly. The games are visual, fast to try, and built as static didof.dev pages with plain-language context behind the interaction.
