If you ever wanted to play chess without looking at the board, or just improve your visualisation skills, but you don't know how to start, then EyeGambit is the App for you. It currently has multiple tools to help you train: Board Recognition - Includes (a) Square Recognition - Get to know the board better and instantly recognise the square and what color it has. (b) Diagonal Recognition - Once you know from the position what a bishop or queen is attacking and what not, they will be less scary. (c) Move Recognition - Identify the moves you hear or see instantly. Memory - See a position or read a list of moves and then either replicate the position on the board or answer questions about the position. Piece Movement - Train the movement of each piece individually by playing a variety of minigames Lichess - You can either train lichess puzzles with the EyeGambit touch of difficulty, or connect to your Lichess account and send/accept challenges with your friends. Play Local Game - Play a game against a friend or a bot on your phone. You can still peak at the board when needed, but with time you will be able to do more moves without looking. Apart from the training, there is also a campaign to follow a progression to learn the skills (currently only for square recognition) More features to come!
