Ive tried many brain exercise games and MindGames is the best IMO. Each exercise runs longer than most games. This strengthens your ability to focus and tests your nerves. Great variety of exercises that challenges your mind unlike any game Ive tried. Some glitches but nothing major. For instance, my score from the trial versions didnt load in the full version when I upgraded. Also, in the game "Anticipation," the same picture is shown after approximately 400 moves. I like to turn off sound and vibration to help me focus.
