How to Play Memory Training
The Memory Training game flashes a sequence of digits on screen for a few seconds, then hides them. Your task is to type the digits back in the exact order you saw them. Adjust the number of digits and the display time to match your skill level. Start with 6 digits (the average person's short-term memory capacity) and increase one digit at a time. You can also shorten the display time to make recall harder.
Why Memory Training Works
This game exercises working memory — the "mental workbench" that holds information for a few seconds while you use it. Adults typically hold about 7 (plus or minus 2) unrelated items in short-term memory, a classic 1950s estimate; more recent research suggests the effective limit may be closer to four chunks, since people often group items silently. Strategies like chunking (grouping digits into familiar units such as phone numbers) and the memory palace can help you make better use of that capacity. Regular practice may help you become more familiar with memory strategies and improve your performance on similar tasks.
