What This Actually Does
Let us be completely clear at the outset: this is a game. The percentage comes from a hash of the letters in the two names and carries no information about anything else. Two names produce the same number every time, and swapping their order does not change it — that is the whole of the mechanism.
It is included here because people enjoy it, in the same spirit as a fortune cookie. It is not a prediction, a personality assessment or advice.
The FLAMES Game
FLAMES is a schoolyard game of unclear origin, popular across South Asia and beyond since at least the 1980s. The procedure:
- Write both names and cross out every letter they share, one for one.
- Count the letters remaining.
- Write out F-L-A-M-E-S: Friends, Love, Affection, Marriage, Enemies, Siblings.
- Count around the letters repeatedly, eliminating one each time, until a single letter survives.
It is a deterministic counting-out procedure, mathematically identical to the Josephus problem — the same structure as counting out players in a game of eeny-meeny-miny-mo. The result is fixed by the letter count, which is why the same pair of names always gives the same answer.
Why Name Compatibility Cannot Work
The reasoning is short. Names are assigned at birth by other people, carry no information about the bearer's personality, and vary by language, spelling convention and transliteration. A person who anglicises their name, marries and changes it, or uses a nickname would get a different score for the same relationship.
Numerology and name-based matching have been tested and show no predictive validity. Any sense that a result "feels right" is the Barnum effect — the same reason horoscopes seem personal — combined with confirmation bias.
What Research Actually Finds
Relationship science has identified real predictors, and none of them involves spelling. The largest body of work comes from John Gottman, who observed thousands of couples and identified four communication patterns that predict separation with unsettling accuracy:
| Pattern | What it looks like | Antidote |
|---|---|---|
| Criticism | Attacking character rather than behaviour | State a need directly |
| Contempt | Mockery, eye-rolling, sarcasm | Build a culture of appreciation |
| Defensiveness | Counter-attacking instead of listening | Accept some responsibility |
| Stonewalling | Withdrawing from the conversation | Take a break and return |
Contempt is the strongest single predictor of separation. Gottman also found that stable couples maintain roughly a 5:1 ratio of positive to negative interactions during conflict.
Other Findings That Hold Up
- Similarity in values matters more than similarity in personality. Agreement about money, children and how to spend time predicts satisfaction; sharing hobbies does not particularly.
- Responsiveness predicts closeness. Turning toward a partner's small bids for attention, repeatedly, over years.
- Conflict is not the problem. Roughly two-thirds of couples' disagreements are perpetual and never resolved. How they are discussed matters more than whether they are settled.
- Shared humour and gratitude correlate with longevity more reliably than almost any demographic factor.
A Note on Fun
None of this means the game is harmful. Playing FLAMES with a friend is a perfectly good way to spend two minutes. It becomes a problem only if someone treats the output as information — which is why the score here comes with the reminder attached.

Frequently Asked Questions
Is the result random?
No, it is deterministic. The same two names always produce the same percentage, and the order does not matter. That makes it a stable party trick rather than a slot machine.
Why did I get a low score with someone I am happy with?
Because the number is derived from letters and means nothing. A long, happy relationship is evidence about the relationship; a percentage from a name hash is evidence about spelling.
Does FLAMES have an official answer?
It has a deterministic one, given a fixed set of rules. Different playground versions cancel letters differently and count in different directions, which is why two people can get different results for the same names.
What actually predicts a lasting relationship?
How partners handle conflict, whether they respond to each other's bids for attention, shared values about the big decisions, and the ratio of warmth to criticism in ordinary conversation. All of it is behaviour, and none of it is in a name.
