Love calculator

Type two names and tap the button. You get a score from 0 to 100% and a short reading. The same two names always get the same score, in either order. It is a game, with no science behind it. The crush test and the friendship test score the same two names again, each in its own way.

The score uses only the letters of the two names. Nothing random goes into it, and nothing is saved. Here is the example on this page, step by step:

1. The two names become lena dan mateo: lower case, no spaces, no accents, in alphabetical order.
2. The name of the test goes in front: love:lena+mateo.
3. The FNV-1a hash of that text is 1,058,495,342.
4. The remainder of a division by 101 is 91. That is the love score: 91%.

The crush test and the friendship test put their own word in front, so the same names get other scores. Each test has its own 30 readings, spread over six bands of the scale.

FLAMES is a paper game for two names. Each letter of the word is an answer: F for Friends, L for Love, A for Affection, M for Marriage, E for Enemies, S for Siblings. Some players read A as Admirers, and S as Sisters or Secret lovers.

1. Write the two names. Cross out each letter that both names have: one in each name for each pair.
2. Count the letters that are left in both names together.
3. Count that far along F, L, A, M, E, S, and go on from F after S. Cross out the letter where the count ends.
4. Start the next count on the letter after it, and repeat until one letter is left. That letter is the answer.

Dengan Lena dan Mateo, cross out the shared letters, one pair at a time. Left: L N dan M T O, which makes 5 letters. Counting 5 along FLAMES crosses out E, M, S, L, A, in that order. The letter left is F: Friends.

Players do not all agree on the details. Some cross out every copy of a shared letter, not one pair at a time. Some count along FLAMES only once and take the letter where the count ends, without crossing letters out. Each way gives its own answer.

Write the two names, and write the words TRUE and LOVE down the side of the page. Count how many times each letter of TRUE is in the two names together, then each letter of LOVE. Add the four numbers of TRUE, and the four numbers of LOVE. Write the two totals side by side: that number is the percentage. Totals of 3 and 4 make 34%.

Dengan Lena dan Mateo: T 1, R 0, U 0, E 2 add up to 3, dan L 1, O 1, V 0, E 2 add up to 4. Side by side, that is 34%.

Full names give more letters, so they give a different result than first names. Like this calculator, the paper tests are games: the letters of a name say nothing about a person.
