Draws as Chords
Map the numbers 1–69 onto a chromatic scale from C3 up to around A7. Each draw becomes a five-note chord. Pick a drawing, press play, and listen to what random sounds like.

How it works
Number n maps to pitch n − 1 semitones above C3 (≈ 130.81 Hz). So 1 = C3, 13 = C4, 25 = C5, and 69 = A7. The five white balls of a draw sound together as one chord.
Each voice is a sine wave with a soft overtone at 2× and 3× the fundamental — just enough warmth to keep the chord from sounding sterile. An ADSR envelope (attack 50 ms, release 300 ms) softens the edges so the chord doesn't click.
Most draws sound dissonant, because a random handful of semitones rarely lines up with any scale. Once in a while a draw hits a near-triad and sounds pleasant for a moment. That's the ear's pattern-matching at work — the same instinct that tempts people to find meaning in random numbers.
