Picture Talk 看圖說話 · describe what you see, beat the hidden sentence

Teacher notes · how this game is built
  1. Make a sentence: one AI call writes a target sentence at the chosen level and theme, plus an English picture prompt that shows exactly that sentence and nothing that contradicts it.
  2. Draw it: the picture prompt goes to an image service as a URL. The student only sees the picture.
  3. Judge: a second AI call compares the student's description with the hidden sentence: points 0–10 for content (who / action / where / details), what was hit, what was missed, one language tip, one better version. Points are for content, not grammar: the tip handles grammar.
  4. Why it is a game: a hidden goal, uncertainty, immediate feedback, a streak bonus (+2 for three rounds of 7+), and a best score kept on this computer. Remove any of these and it becomes a worksheet.
  5. Where the teacher is: the level text and the theme list at the top of the file, and the two prompts (makePrompt, judgePrompt) near the bottom. Change text, not architecture. Check three rounds yourself before class: does the picture actually show the sentence?
