The basic idea of this game is to see how many characters you can remember. The sequence of operations is as follows: Set up your parameters below: Click on the "Click here to start" button. You will be presented with several characters (digits or letters depending on the choice below). After a certain length of time (also settable below) The characters will disappear. After a delay (settable below) you will be asked to enter the digits you saw, you can use either the on screen keyboard or the computer keyboard. Click on the "Check my Numbers" or "Check my Letters" button or use the "Enter" key on the computer keyboard. Your result will be checked. To progress to the next level (1 extra character added) click on the "Click for next board" button or press the "Enter" key. If you want to make it harder then on the panel below then set the "Do you want to have your attention diverted during the wait period" option to "yes". This will mean that instead of a delay before entering the characters you will be given two simple multiplication sums to do as a way of diverting you from remembering the Characters. Good Luck.
