BLINDFOLD includes a Test and a Game. It is intended to improve the speed of comprehension and to extend the capacity of operative memory. These two parameters are of great importance both for progress at school and for successes in chess.
From point of view of chess this program is aimed at diagnosing and training a chessplayer's intellectual faculties called variations calculation and visualization (see article What is Variation Calculation?).
The aim of the Test is to reveal the extent to which your operative chess memory has been developed. That is, how successful you can be in keeping track of the numerous chessboard situations which replace one another during the kaleidoscopic counting of variations.
The accuracy of visualization of piece positions and movements in the course of imaginary play determines the degree of correctness of the player's positional evaluation and, consequently, his/her decisions. Information about what practical benefit can be derived from the testing results and how to use them to improve your chess skills you can find in the article Blindfold: Interpretation of Testing Results.
