Can you hear the difference between 440 Hz and 445 Hz?

ToneGame is a deceptively simple challenge: listen to a pure tone,
then reproduce it as precisely as possible. No music theory required.
No instruments needed. Just your ears, your instinct, and a slider.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎯 HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

A tone plays. You listen. The tone stops.
Now find it. Drag the slider until you feel it's right. Submit.
Your score depends on how close you are — tenths of a Hz matter.

Simple to learn. Almost impossible to master.
