How to Improve Your Memory: 7 Proven Techniques (Plus Free Practice Games)
Memory isn’t fixed. Modern neuroscience has firmly established that the brain remains plastic — capable of forming new connections and improving existing ones — well into old age. The question isn’t whether you can improve your memory, but how.
Here are 7 evidence-based techniques, each paired with a practical way to apply it today.
1. The Memory Palace (Method of Loci)
Used by ancient Greek orators and modern memory champions alike, the memory palace technique involves mentally “placing” items you want to remember at specific locations along a familiar route — your home, your commute, your school hallway.
When you want to recall the items, you mentally walk the route and “pick them up.” Brain imaging studies show this dramatically increases activity in the hippocampus, the brain’s memory hub.
💡 Practice: Start with Number Memory — as numbers appear, assign each one a vivid visual anchor in an imaginary room.
2. Spaced Repetition
Cramming works for tonight’s test. Spaced repetition works for life. The technique involves reviewing information at increasing intervals — today, then tomorrow, then in 3 days, then a week — timed to just before your brain would forget it.
This exploits the “spacing effect,” one of the most replicated findings in cognitive psychology. Apps like Anki automate the scheduling, but you can apply the principle manually too.
3. Active Recall (Testing Yourself)
Re-reading your notes feels productive but produces surprisingly weak memories. Testing yourself — trying to recall the information without looking — is up to 4× more effective, according to research published in Science.
💡 Practice: Our General Knowledge Quiz is pure active recall — it forces your brain to retrieve answers from scratch rather than recognise them from a list.
4. Chunking
Your working memory holds about 4 “chunks” of information at once. A phone number like 07700900123 is 11 individual digits — too many to hold. But chunked as 077-009-00123, it becomes 3 items. Credit card numbers use the same principle.
Actively chunking new information when you encounter it dramatically reduces the cognitive load needed to remember it.
5. Elaborative Encoding
The deeper you process a piece of information — connecting it to things you already know, asking “why?” and “how?” — the stronger the memory trace. Surface processing (“this word is printed in blue”) produces weak memories; deep processing (“this concept connects to what I learned last week about X”) produces durable ones.
6. Sleep
This one isn’t optional. During sleep — particularly during slow-wave sleep and REM — your brain replays the day’s experiences, consolidating short-term memories into long-term storage. One night of poor sleep degrades next-day memory formation by up to 40%, according to UC Berkeley research.
No memory technique compensates for chronic sleep deprivation.
7. Exercise
Aerobic exercise triggers the release of BDNF (brain-derived neurotrophic factor) — sometimes called “Miracle-Gro for the brain.” It promotes the growth of new neurons in the hippocampus and is one of the few interventions shown to physically increase hippocampal volume in adults.
Even a 20-minute walk before a study session measurably improves memory encoding.
Put It Into Practice
The best memory training combines multiple techniques. Start with a daily practice session on BrainKing’s free memory games — just 10–15 minutes a day. Track your progress on the leaderboard and watch your scores climb as your memory strengthens.
