Reaction Alert
Monitor a signal stream: alert on the target, pass the decoys.
How to play
Remember the target meaning. Inspect each signal, then choose Alert or Pass. Accuracy—not reaction speed—counts.
Use Tab and Enter, touch, or a mouse. Feedback follows every response.

Tab and Enter, touch or mouse. Pause at any time. Timed mode displays active time without a deadline. Projector mode uses this same device; it is not a networked room.
Guided practice: the final vocabulary response is checked by the server when assigned. Puzzle performance, timing and hints are not independent assessment evidence.
