The idea
Every playground had a ritual for this — scribbled pyramids, crossed-out letters, a percentage delivered with total authority and zero explanation. Charming, but opaque. This instrument keeps the fun and replaces the mystery with a method you can check: four measurable ingredients, a fixed number of points each, every one of them shown on your result.
The philosophy is simple: if a game hands you a number about something as lovely as two names together, you deserve to see exactly where that number came from. So the poster doesn’t just give a score — it gives the receipts.
How it’s measured
The scale awards 100 points across four ingredients:
Sound harmony …… up to 25 (matching vowel balance)
Spark ………………… up to 20 (letters only one of you brings)
Star alignment … up to 15 (your two name numbers)
Common ground pairs off the letters your names share, one for one, and scores the overlap against your combined length (the Dice coefficient, a real similarity measure). Sound harmony compares your vowel percentages: names with a similar vowel-to-consonant balance “sing” at the same pitch, so a smaller gap earns more points. Spark rewards difference — the distinct letters only one of you brings, because chemistry needs contrast as much as overlap. Star alignment reduces each name to its traditional single-digit name number (A=1 … I=9, repeating) and scores the pair on a fixed chart: identical numbers 15, numbers summing to ten 13, neighbours 11, and so on down to 3.
Accents are folded (Nicolò and Nicolo read the same), spaces and punctuation are ignored, and the whole thing is deterministic and symmetric: the same two names always produce the same score, in either order.
Questions, answered
Will the same two names always get the same score?
Yes — the method is pure arithmetic, so it is perfectly repeatable, and swapping the order of the names changes nothing. If your result differs from a friend’s, one of you spelled something differently.
Is this scientifically real?
The mathematics is real and fully disclosed; the idea that letters predict love is not, and we would never pretend otherwise. Treat it as what it is: a beautifully honest parlor game. Real chemistry is written by people.
Why do two identical names not score 100%?
Identical names max out common ground, harmony and alignment — but score zero on spark, landing at 80%. The scale is telling you, with a straight face, that chemistry needs at least a few letters of difference.
