An electronic game board (106 a) that is foldable and rollable includes a processing circuit (302), a play area (206) and indicators (310). Game pieces are arranged on the play area (206) for facilitating a game. Indicators (310) are arranged in the play area (206) and indicate to a player on a first game board an initial and end position of a game piece played by an opponent player on a second game board or by an AI player. The electronic game board (106 a) also includes sensors (308) to validate a move of a game piece.

The present application relates to a klotski game including a plurality of game pieces, a game board and a prompter. The plurality of game pieces includes a decisive game piece. The game board is configured to accommodate the plurality of game pieces and the game board is provided with an exit. The prompter is configured to indicate that a game of the klotski game is over when the decisive game piece is moved to a position corresponding to the exit on the game board.

The present disclosure belongs to the field of intelligent hardware, and particularly relates to an intelligent chess device and a modular chess device. The intelligent chess device of the present disclosure includes a chessboard, the chessboard being divided into a plurality of chess grids, and each chess grid corresponding to one piece of chess piece position information; a control module; a chess piece information input module, configured to at least receive chess piece position information input by a user and communicate with the control module; and a display module, configured to be controlled by the control module to respond to the chess piece position information input by the user, so as to present corresponding display information on the chessboard.

A chessboard toy is provided. A first driving coil is arranged on an inner ring of a knob, and a second driving coil is arranged on a rotating member; and the first driving coil and the second driving coil mesh with each other, so that a rotation sensing member can be controlled by direct mechanical transmission; mechanical motion of the knob can be converted into an electrical signal of the rotation sensing member; and use of a light sensing mechanism or a magnetic sensing mechanism is avoided. Therefore, structural complexity and a fault rate are reduced. In addition, compared with the light sensing mechanism and the magnetic sensing mechanism that have high costs, a technical solution can also significantly reduce production and manufacturing costs.
