Notes fly towards you down the lanes. Tap each lane's button just as its note reaches the glowing line, and you play the song! With 3D glasses the notes zoom right out of the screen.

How deep?
Less depth is easier on the eyes. More depth pops out more.
1. Hide the green bar
Put the glasses on and cover the eye behind the green lens, so you look only through the red lens. Slide left until the green bar disappears.
2. Hide the red bar
Now cover the eye behind the red lens, so you look only through the green lens. Slide left until the red bar disappears.
3D mode is just a fun way to play. If your eyes feel tired, take a break or play without glasses.
HOW TO PLAY
Each lane is one musical note, low on the left and high on the right, just like a piano. The buttons at the bottom show the note names.
Notes fly towards you down their lanes. Tap the lane's button just as the note touches the glowing line. On a computer, use the keys A S D F G H.
Right on time is PERFECT, a little early or late is GOOD. Notes you miss stay silent, so listen: when you play well, you hear the whole song! Taps when no note is there cost a little, so don't just tap everything.
Hit 90% of the notes for ⭐⭐⭐ and 70% for ⭐⭐. Any star opens the next song. Get a star on a song to open its ⚡ fast version.
Coins buy new note shapes. A long run of hits in a row (a combo) scores extra.
HOW 3D WORKS
Try this: look at your finger with one eye and then the other. It jumps! Each eye sees from a slightly different place, and your brain uses the jump to judge distance: stereo vision.
Song Tunnel draws everything twice, from two eyes a little apart, in red and in green (or blue). The glasses give each eye its own picture. The glowing line sits on the screen, far notes are deep inside it, and notes you miss fly out past you.
Music science: a note is the air shaking. The note A shakes 440 times a second. Each lane to the right shakes faster, so it sounds higher. Go up eight white piano keys and the air shakes exactly twice as fast: that is called an octave.
