Free classroom noise meter game

How it works & FAQ

HushHushPlush is a free classroom noise meter for your board. Get quiet, catch Hushies, collect all 234: every stretch of quiet brings a new creature into the scene, and noise sends them running. Classes race to fill the Hushie Codex on a leaderboard.

How it works

  1. Open HushHushPlush on the board and allow the microphone. Set the noise limit or calibrate it in 5 seconds.
  2. Pick one of 12 illustrated worlds and start work time. Quiet brings Hushies in; too loud and they leave.
  3. Check the Hushie Codex and leaderboard to see which class period has caught the most.

What you get

  • 12 illustrated scenes, from Whispering Woods to Haunted Hollow and holiday themes
  • A live noise meter with a limit you set or calibrate in 5 seconds
  • Built-in timer and your own note, shown right inside the scene
  • Get quiet, catch Hushies: classes race to collect all 234 in the Hushie Codex
