The detective framing gives grammar practice a reason to exist. Students are solving something, not completing something.
Each round shows a score and an in-round streak counter, so students compete against their own previous try rather than against a classmate.
A round takes about 5–10 minutes, which fits a warm-up, a station, or an early-finisher slot.
Every answer comes with a short explanation, so a wrong choice becomes a quiet correction on screen instead of a public one in class.
