What are the best games for improving focus and attention?

Games that improve focus and attention typically require sustained concentration and resistance to distraction. Memory matching games build visual attention and concentration. Pattern recognition games train attention to detail. Speed matching games improve selective attention - focusing on relevant stimuli while ignoring distractions. Dual-task games (controlling two things simultaneously) enhance divided attention. Puzzle games like Sudoku and nonograms require sustained focused thinking. For ADHD or attention training, consistency matters more than duration - 10-15 minutes daily is better than hour-long sessions weekly. Start with easier difficulty and gradually increase as your attention span improves.
