TWO SENSORS · NOISE REMOVAL · LOCATION ESTIMATEJUL 24 · JAPAN EXPORT · 20 SECONDS
HEAR IT BEFORE YOU DIG!
Tap the pipe heard by BOTH sensor A and sensor B.
- Read the A and B signal on each pipe.
- Tap the pipe where both are blue. One-sided signals and red road noise are false leads.
- A wrong check stays in the same round. A correct check patches the pipe and restores water.
The field verification measured between two points roughly 500 m apart on pipe up to 1300 mm wide. Accuracy varies with surrounding noise. This unofficial game simplifies the detection idea; it does not reproduce the real analysis.

About this news game
Why this mechanic? The announcement describes measurements from multiple points, noise removal, and suspected-sound location estimation. The game turns that into one readable action: choose the pipe heard by both sensors, not a one-sided signal.
