This site offers a large catalog of quick-to-play visually appealing browser-based flash games that claim to boost and sharpen your cognitive powers. They are organized into progressive levels of difficulty and different categories of brain challenge – like “cognitive control” and “processing speed.” The idea is to incorporate a few minutes of game play into your daily routine… which they have made easy and pleasant to do. The games don’t require any special knowledge or preparation – they are largely interactive variations on games you’d remember from childhood like the popular card game concentration.
