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. Hum to Melody cleans a short hummed melody into replayable browser-native notes. Gefühlsrad Trainer teaches 78 German and English emotion words through a filled emotion wheel. The local tools keep practice lightweight and private.
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.
