Red Eye After Practice: Routine or Risky?
Dedicated to students who report small changes before they become big ones.
A student notices one red, irritated eye after a busy day and wants the fastest answer. The tempting move is to treat it like a routine annoyance, but the better reasoning path starts with context. This introductory DxDetective case gives players a compact decision scene with useful checks, low-value shortcuts, and a final call that depends on earned clues rather than guesswork. It is designed for mobile play and classroom discussion because the facts can be scanned quickly while the decision still has stakes. The public page can describe the domain, difficulty, round count, setting, diagnostic option types, and skill focus for search and discovery. It must not reveal the hidden danger signal, the source-backed explanation, or the safest final action until the player reaches the result screen.
