Select all pieces that are under attack. Like in the blindchess challenge, it is possible to control the number of blind moves in the settingsscreen. The standard level can be used by beginners, to learn to find all the pieces under attack. When the number of blindmoves increases, the difficulty increases as well. Your board visualisation skills will improve by doing these exercises.
