The Millennium ChessGenius Exclusive and Supreme Tournament 55 are elegant wooden sensory chessboards with 81 LEDs as move indicators and fully automatic piece detection. The system connects to a computer chess unit in a separate cabinet or to other chess playing devices over bluetooth using the Chesslink.
Since v5.6, Chess for Android supports all the Millennium electronic chessboards on devices with Android 6.0 and up. After pairing the tablet or phone with the chessboard (needs to be done only once), long press the notation window in Chess for Android to open the extended menu. Then select "Connect to EBoard", pick either the Millennium BLE (Bluetooth Low Energy) or the Millennium bluetooth (classic), choose an initial orientation (white at bottom when checked) and LED function (steady when checked or blinking otherwise), use the slider to set the brightness of the LEDS, and press "Connect". Then select "Millennium Chess" from the list of paired devices.
Setting up the start position with white on either the bottom or top of the electronic chessboard will start a new game with Chess for Android using that orientation. Move a piece to make a move, and follow the LEDs or the GUI to make the computer's response. To capture, remove the opponent's piece from the chessboard. To castle, move the king first two squares to the left or right. To capture en-passant, move your own pawn first before removing the opponent's pawn. To promote, move your own pawn to the last rank, select the promotion piece on Chess for Android, and then replace the pawn with that piece on the electronic chessboard. To set up a position, long press the notation window, pick "Position Setup", after which Chess for Android continuously syncs its internal chessboard with the electronic chessboard. After pressing "OK", the game can proceed from the given position (if valid).
If an illegal move is made, or the electronic chessboard is somehow out-of-sync with Chess for Android, the LEDs are used to indicate the difference. Correct all differences before proceeding with the game. Likewise, if the game navigation buttons are used to go backward or forward in a game, the LEDs indicate how to resolve differences.
Other features, including playing against third party chess engines, are explained in the Chess for Android Manual and the instructional videos below.
