Working memory is our capacity to temporarily hold information that can be used to take quick decisions, calculate and solve problems on the fly. Brain training aims at strengthening this part of our brain. While large studies are still underway to prove training's utility in improving our working memory, some smaller published studies have already found it to be beneficial in certain age groups such as children and senior citizens. So, it doesn't hurt to give some of these games or exercises a try.

Train on the web

Braingle is a wonderful site full of little tests, memory puzzles and more. The site also has an IQ test which can give you an idea of your mental capacity. I particularly liked the mentalrobics section, where you can work on improving your mental capacity. It even has a forum where you can post games you found or discuss your test results with other participants or play social games like chess and checkers. However, you will have to register to get access to this, the basic account is free. You can also try Games For the Brain and Brainturk, which host a similar array of brain training games.
