Free Brain Games for Adults

Looking for a quick mental workout? These free brain games each exercise a different skill. Simon Says and Memory Match test your short-term memory, Sudoku and Minesweeper train logical deduction, Guess the Country sharpens your geography, and Daily Word gives your vocabulary a daily stretch. Each takes just a few minutes, so they're easy to fit into a coffee break.

They're games first, not a clinical brain-training programme — but watching your best scores improve is half the fun. Free, with no login or download.
