How to Master Name Rarity
TLDR: The game shows two first names and asks which is rarer. Both come from one list: the United States Social Security Administration top 1000 baby names of 2024, one list for boys and one for girls. That single fact decides every round. You are reading 2024 fashion, not how many living people carry a name.
Where the Names Come From
One country, one year, first names only. The list holds 1000 boys’ names and 1000 girls’ names from births registered in the United States in 2024. A name outside those two lists has no rank in this game at all.
Both names in a round always come from the same list, so you never compare a boy’s name against a girl’s name. You choose which list to draw from: boys, girls, or both.
Above the game sits a lookup. Type any name and you get its rank, a band (top 10, top 100, top 500, top 1000 or outside), and a “one in N” figure for births of that sex.
How the Rank Gap Ramps
Two levers drive the challenge, and both are exact. Your age baseline sets the opening rank gap between the two names, ranging from a wide separation on younger baselines down toward narrow gaps on adult baselines. Winning streaks tighten that gap further, shaving five places off the rank difference with every win until adjacent ranks duel head to head. At the same time, your streak pushes the rank floor deeper into the list by 15 places per win, moving from familiar top names toward obscure entries.
Pick one list and stay in it. The default draws from both lists, which means you are learning two sets of a thousand names at once. Choose boys or girls for a few runs instead. One list at a time is how the ranks actually stick, and the setting is remembered between visits.
Read 2024, Not History
✅ A name your grandparents used ranks low here. Harold sits at 988. Linda is 835. Jennifer is 547. Dorothy is 431. Patricia and Susan are not in the top 1000 at all. Nothing accumulates across decades in this list, so a 1955 favourite that nobody chooses now is genuinely rare among 2024 babies.
Some old names did come back and now rank high. Eleanor is 14, Elizabeth is 17, William is 10 and James is 5. So “old” is not a rule by itself. The question is always whether the name is in use right now.
⚠️ Caution · do not trust the people you know. Your sample is one age group in one place, and it is tiny. If you know five people called Sarah and nobody called Amelia, that tells you nothing about the 2024 list. Amelia is third.
💡 Tip: Learn the 2024 top ten of each list first. Boys: Liam, Noah, Oliver, Theodore, James, Henry, Mateo, Elijah, Lucas, William. Girls: Olivia, Emma, Amelia, Charlotte, Mia, Sophia, Isabella, Evelyn, Ava, Sofia. Twenty names cover the most common pair you will ever be shown.
Spelling Splits a Name
Each spelling holds its own rank. Katherine is 175, Catherine is 320 and Kathryn is 717 · three entries for one spoken name. Anna is 94, Anne is 649, and Ann is not in the list at all. So when one name in a pair has well-known variants and the other does not, the spelling in front of you is rarer than the sound of the name suggests.
💡 Tip: A short form is its own entry too, and it is usually the rarer one. Kate sits at 535 while Katherine sits at 175. When a pair holds a full name and a short form of a different name, the short form is the safer answer.
Common Mistakes
⚠️ Caution · an unusual sound is not a rare name. Arabella sits at 206 and Xander at 216, both inside the top quarter of their lists. Robert sounds ordinary and sits at 90. How a name sounds to you is noise. The rank is the signal.
Treating a unisex name as split. A name can hold a rank in both lists at once: Jordan is 104 for boys and 539 for girls. That is interesting, but a round draws both names from one list, so only that list’s rank decides the answer.
Waiting for certainty on narrow gaps. A fifty-place gap is small enough that two names can both feel ordinary. Reason from the two levers you have, the year and the spelling, then commit. The reveal shows both ranks, so a loss still teaches you two positions in the list.
Practice
💡 Tip: Play on one list until the top hundred feels familiar, then mix both lists. After a loss, put the name you got wrong into the lookup above and read its rank. That one step turns a wrong answer into a position you remember, which is the whole point of the game.
The skill transfers to any question of the form “which of these two is rarer” when you have a ranking rather than a count: a word in a language, a surname in a register, a part number in a catalogue. You learn to ask which list you are reading before you answer.
Name Rarity
Look up how rare your name is in the US top 1000, then play streaks guessing which of two names is rarer. The gap shrinks as you climb
