What this test measures
One word sits on the screen at a time, and you make one call per word: has it appeared earlier in this run, or not? Every correct call scores a point and brings the next word. Every wrong call burns one of three strikes, and the third strike ends the run. There is no timer — the word waits for your answer — so the score measures judgement, not speed.
Psychologists call this kind of task recognition memory: deciding whether something in front of you matches something already stored. It is a different job from recall. You never have to produce a word from nothing — only to recognize one — which is why the early minutes of a run feel almost insultingly easy. The difficulty arrives later, and it arrives on schedule.
Why the words start to blur
The trap in this test is not forgetting — it is remembering too much. By the fiftieth word your head holds a long pile of everyday nouns, and every new candidate has to be checked against all of it. Similar items in memory compete with each other, a well-documented effect known as interference, and this test is built almost entirely out of that effect. The pool is deliberately ordinary — kitchen things, weather, fruit — because common words resemble each other's company. "Did I see spoon, or was that fork?" is the exact failure this test is designed to produce.
Around four out of ten words are repeats, drawn from anywhere in your run so far — the word you saw two screens ago and the one from three minutes back are equally fair game. The one thing that never happens is the same word twice in a row; that would test nothing.
The rules that keep the score honest
Your score is the number of correct calls before the third strike, and that is the whole formula. Nothing is weighted, nothing decays. A wrong call costs a strike but not points, so one slip late in a long run does not erase the run. Records stay on your device, the leaderboard takes a nickname and nothing else, and this page shows no percentile — we could not find a published study whose method matches a browser version of this task, so we would rather show a plain score than invent a comparison. That is the standard we apply to every test on this site.
Two ways to be wrong
The scoreboard treats every miss the same, but from inside a run the two mistakes feel nothing alike. Calling a new word SEEN — a false alarm — is interference doing exactly what it does: the word simply resembles the crowd already in your head, and familiarity turns out to be a feeling that can be faked. Calling a repeat NEW is the opposite failure, and it usually belongs to a word that slid past on its first visit while your attention was still busy with the previous call. Noticing which of the two you make more often is worth something. Heavy on false alarms, and you are trusting the glow of familiarity too much — before pressing SEEN, ask whether you can actually place the earlier meeting. Heavy on misses, and your first-visit impressions are thin — give each new word half a second of real attention, because that half-second is the entire investment this test rewards.
Frequently asked questions
Is this a vocabulary test?
No. The pool is a few hundred everyday nouns on purpose — window, carrot, umbrella. If any word made you reach for a dictionary, the test would start measuring your reading instead of your memory. Knowing the words is assumed; the question is only whether you saw them tonight.
What is a good score?
There is no published norm for this format, so we will not print a percentile. As a rough feel from how runs tend to go: most people lose their third strike somewhere in the twenties or thirties, staying sharp past fifty is a strong run, and three-digit scores mean the interference never got a grip on you.
Do the same words repeat every run?
The pool is shuffled fresh each run, and which words repeat — and when — is drawn at random as you play. In the daily challenge everyone gets the same shuffle and the same repeat schedule, so daily scores are comparable board to board.
Can I get better at this?
Yes, and the improvement is a technique, not a bigger head. People who score high usually stop trying to hold the whole list and instead make each word vivid the moment it appears — picture the umbrella, put the carrot somewhere absurd. A word given one second of attention on its first visit is much harder to confuse on its second. Guessing patterns, by contrast, does not work: the repeat schedule is random and owes you nothing.
