🎻 Violinist Visuals

Train your eye to recognize simple fractions — the way a violinist finds 3/5 the way up a string without frets.
Starts at 1/2. Every correct answer pushes the fraction one denominator finer — 1/3, 1/4, 1/5... — for as long as your eye can keep up.

How to play:
• Everything starts at 1/2 — the simplest fraction. Answer right and the game climbs to 1/3, then 1/4, 1/5, and beyond.
• Each correct answer is worth as many points as its denominator — a 1/2 question is worth 2 pts, a 1/9 question is worth 9 pts, and so on.
• There's no fixed ceiling: the game keeps climbing until it finds the smallest denominator you can no longer reliably judge by eye.
• The game ends once you've missed 5 of your last 6 questions — your score at that point is final.
