Provided is a solid puzzle block ( 1 ). The solid puzzle block has a connecting groove ( 13 and 33 ) open from the top to the bottom of a side surface ( 11 and 31 ) of its main body to allow cross-connecting of two blocks, and a connecting peg ( 14 ) and connecting hole ( 15 ) formed at either end of the connecting groove ( 13 ) on the side surface ( 11 and 31 ) to allow side-connecting of two blocks. In order to impart a firm cross-connection, a plurality of embossings ( 12 ) are formed on the left and right surfaces of the connecting groove ( 13 and 33 ) and the contact portions ( 42 ) of the upper and lower surfaces ( 40 and 41 ) contacting the connecting groove ( 13 and 33 ). At an end surface ( 16 and 36 ) between the left and right surfaces of the connecting groove ( 13 and 33 ) is fixed a connector ( 17 ), to which an operating unit ( 21 ) located inside the main body is connected electrically. Although the firmly connecting block is not of an assorted variety, it can arouse enjoyment and curiosity in users of all ages.
