A name you can't quite recall, keys you can't find, a book you barely remember three weeks after finishing it. These small memory lapses happen to everyone, and they all raise the same question: can you actually train your memory, or are you stuck with the one you have?
The science of learning has encouraging news: memory is not a fixed store, it is a cognitive function you can maintain. It gets stronger when you use it, with novelty, effort and consistency. Here are the games and exercises that genuinely stimulate it, what the French Alzheimer's association France Alzheimer says about them, and how to turn them into a habit that takes just a few minutes a day.
Memory can be trained like a muscle
We often talk about "memory" as if it were a single thing, but there are several kinds. Working memory holds a piece of information for a few seconds, just long enough to use it (a phone number you are about to dial). Long-term memory durably stores what you know and what you have lived through. Beyond these two, researchers also distinguish visual memory, verbal memory (words and ideas), spatial memory (places and positions) and immediate memory.
They all have one thing in common: they are consolidated through use. Every new thing you learn creates or strengthens connections between neurons, and every time you retrieve a piece of information, you make that path easier to follow next time. Researchers use the term cognitive reserve for this capacity, built up over a stimulating life (education, reading, intellectual activities, social life), to better compensate for the effects of brain aging.
The practical takeaway is simple: the best way to preserve your cognitive abilities is not to spare them, it is to put them to work, a little, often, and ideally in a way you enjoy.
The 10 games France Alzheimer recommends to stimulate memory
The French association France Alzheimer sums up this idea well in its article 10 jeux pour stimuler la mémoire (10 games to stimulate memory, in French): "The brain is a muscle, and we tend to forget it." The association points out that exercising your memory is useful both to reduce the risk of dementia and to slow the progression of Alzheimer's disease, and it recommends letting games become part of everyday life. Here is its selection, with what each game works on:
| Game | What it trains |
|---|---|
| Memory (Concentration) | Visual and visuospatial memory |
| Jigsaw puzzles | Visual memory, concentration |
| Card games (bridge, belote, tarot) | Cognitive abilities, remembering the cards played |
| Scrabble, crosswords, word searches | Verbal memory |
| Trivial Pursuit and quiz games | General knowledge, long-held knowledge |
| Chess and checkers | Spatial memory, strategy, planning ahead |
| Mastermind | Reasoning, deduction, memory |
| Simon | Immediate memory, motor skills |
| Happy Families | Memory, association |
| Memory game apps | Digital versions of logic and memory games |
What makes these games effective is not the game itself, but the three ingredients they combine: a retrieval effort (finding a card, a word, an answer), an adjusted level of difficulty (hard enough to engage you, easy enough not to discourage you) and consistency, because we happily go back to what we enjoy.
Quizzes: the most underrated memory game
One line in France Alzheimer's list deserves a closer look. About Trivial Pursuit and quiz games, the association explains that they involve "retrieving a piece of information in order to answer a question", drawing on knowledge sometimes acquired in childhood, which psychologists call crystallized intelligence.
Retrieving a piece of information to answer a question: that is the exact definition of active recall, the learning technique most solidly backed by research. Testing yourself, even when you get it wrong, locks information in far better than rereading it. We explain this mechanism, the testing effect and the forgetting curve in our guide to active recall.
Quizzes have another advantage over many memory games: they don't just exercise your brain, they enrich it. A game of Memory trains your visual memory on pictures that don't matter; a good quiz trains your memory on ideas worth remembering. You stimulate your cognitive functions and, at the same time, build your general knowledge.
How Cobalt puts your memory to work
That is exactly the idea behind Cobalt: turning a moment of reading into a memory exercise. France Alzheimer includes memory game apps in its selection; Cobalt offers a learning-focused version, where what you memorize is also what helps you grow.
- New ideas every day: each summary distills the essentials of a nonfiction book (psychology, history, science, philosophy) into an average of 8 minutes of reading. Novelty is one of the most powerful stimulants for the brain.
- A quiz at the end of every summary: a few questions to retrieve the key ideas instead of simply rereading them. That is active recall applied to reading.
- Mnemonic devices: images and associations that anchor the concepts in your long-term memory.
- Audio format: listen to a summary on your commute, then test yourself on it, to work your verbal memory without a screen.
- A short, regular format: a few minutes a day beats one long session a month, which is the whole point of microlearning.
An important note: Cobalt is a learning app, not a medical device. It does not claim to prevent or treat any disease. If you or someone close to you notices unusual or persistent memory problems, the right thing to do is to talk to a doctor.
A 15-minute daily memory routine
There is no need to overhaul your schedule. Here is a simple routine that combines the ingredients above:
- 8 minutes: read or listen to a summary on a topic you don't know yet.
- 2 minutes: take the quiz without rereading, then check your mistakes. A wrong answer that gets corrected is often encoded better than one you got right the first time.
- 1 minute: write down or say out loud the idea that struck you most, in your own words.
- Two days later: retake the quiz. This spaced recall comes just before you would forget, when it is most useful.
- In the evening or at the weekend: a game of chess, cards or a crossword, ideally with other people.
After a month, you will have exercised your verbal memory, working memory and long-term memory some thirty times, and you will walk away with the key ideas from just as many books. To go further on reading itself, our 7 techniques to remember what you read complement this routine.
Habits that matter as much as exercises
Games and quizzes are not everything. Several lifestyle habits weigh at least as much on memory and cognitive abilities:
- Sleep: it is during the night that the brain consolidates what it learned during the day. Studying late at the expense of your sleep is a bad trade.
- Physical activity: moving regularly improves blood flow to the brain and is among the factors most often associated with healthy cognitive aging.
- Social connection: talking, debating and playing with others constantly draws on your memory. Telling someone what you have learned is actually one of the best active recall exercises there is.
- Novelty: a new subject, a language, an instrument. The brain adapts to routine; it is stimulated by what it doesn't know.
Where to start
Pick just one habit and stick with it for two weeks: one summary and one quiz a day, or a weekly card game with friends. Consistency matters more than intensity, and enjoyment is the best guarantee of consistency.
More than 40 summaries are free to read at https://www.cobaltapp.io/en/resumes, and the Cobalt app, with its quizzes, mnemonic devices and audio summaries, can be downloaded at https://www.cobaltapp.io/download. Eight minutes of reading, two minutes of quiz: enough to work your memory every day while learning something along the way.
