Zerdly Memory is a game and a personal benchmark — a fun way to test your recall. It is not a medical test, an IQ test, or any kind of health or cognitive assessment. Your bests are kept on your device.
Test your memory for free with four quick browser games — visual, sequence, number and verbal memory. Each one gets harder as you go, and Zerdly keeps a separate best for each so you can track your progress. It’s a fun benchmark, not a medical test.
Visual memory
A grid of tiles flashes a pattern; once it disappears, tap the tiles you saw. Every level adds tiles and, eventually, a bigger grid. You have three lives, so a slip won’t end the game straight away.
Sequence memory
Watch the squares light up one after another, then repeat the order. Each round adds one more step, so the sequence keeps growing until a single wrong tap ends the run.
Number memory
A number appears for a moment, then vanishes — type it back from memory. It gains a digit every round, and the longest number you can reproduce is your score.
Verbal memory
Words appear one at a time. Say whether each is NEW or one you’ve already SEEN this game. It quietly mixes in repeats more often as you go, testing how many words you can keep track of.
Is this a medical memory test?
No. Zerdly Memory is a game and a personal benchmark — an enjoyable way to challenge your recall and watch it improve. It is not a medical test, an IQ test, ADHD or dementia screening, or any kind of health or cognitive assessment, and no result here can diagnose anything.
How Zerdly Memory scoring works
Each game reports one simple number: the level reached, the longest sequence, the most digits, or your verbal points. Zerdly deliberately keeps these separate rather than blending them into a single figure — different kinds of memory aren’t really the same measurement.
Your memory bests and the Daily challenge
Zerdly keeps a separate best for each of the four games in a bests panel — deliberately never a single combined figure. The 🔥 Daily rotates through the four modes, giving everyone the same seeded challenge each day with a local streak. Your recent runs are listed too, all on your device.
Frequently asked questions
What is an online memory test?
It's a set of short games that challenge different kinds of short-term memory — remembering patterns, sequences, numbers and words. Zerdly reports how far you get in each so you can benchmark yourself and track improvement.
What are the four memory games?
Visual memory (remember which tiles lit up), sequence memory (repeat a growing flash order), number memory (recall a number that gets one digit longer each round) and verbal memory (say whether each word is new or one you've seen).
Is this a medical or IQ test?
No. Zerdly Memory is a game and a personal benchmark — a fun way to test recall. It is not a medical test, an IQ test, or any kind of health or cognitive assessment, and it can't diagnose anything.
How is my score worked out?
Each game has its own simple score: the level you reach in visual memory, the longest sequence you repeat, the most digits you recall, or your points in verbal memory. Zerdly keeps a separate best for each — there is no combined 'memory score'.
Does it work on a phone?
Yes — the tiles and buttons are touch-friendly, and number memory brings up a numeric keypad. Everything runs in your browser.
Are my results saved?
Your best in each game is stored locally on your own device, in your browser. Zerdly never receives your results.
