Free Online Brain Games

The human mind is one of the most complex mechanisms of the human body. According to Tony Buzan, author of Head Strong, “The human brain has the capability of initiating ideas more than the number of atoms in the known universe.” The human brain works much better and quicker than imagined, and that’s why we need to boost our intelligence, memory and sharpness in solving difficult day-to-day problems. Various self-help books, board games and puzzle games have been devised to train the brain, but we can only boost our intelligence and memory if we “exercise” our grey cells regularly.

We humans seek different ways to train our brains, be it solving crosswords or scratching our grey cells to solve a Sudoku puzzle. With the PC and internet revolution, brain games have evolved from simple paper-pencil puzzles and brain teasers to online brain teaser games with attractive graphics and play value. A simple logic puzzle like Sudoku now has different online variations that make everyday puzzle-solving much entertaining and fun. Brain teasers have also evolved in the form of online room escape games, which tests your intelligence by providing few solutions to escape a locked room. Today, there are several online brain games and brain teaser games over the internet. Numerous sites are dedicated to provide the best teasers, puzzles, riddles and other brain games to sharpen your deductive logic kills and improve your intelligence. Here’s an excellent compilation of free online brain games and free websites that have a nice selection of brain teaser games:
