A magnetic toy includes a polygonal housing having a plurality of side walls, an accommodation portion located inside the polygonal housing and adjacent to a side wall of the polygonal housing, and a magnet having a length and a width oriented orthogonal to the length. The magnet is accommodated in the accommodation portion. The accommodation portion includes a first end portion, a second end portion opposite the first end portion, and an accommodation space located between the first end portion and the second end portion. A width of the first end portion in a direction orthogonal to the side wall is equal to or greater than the width of the magnet. The width of the first end portion is less than the length of the magnet. A width of the accommodation space in the direction orthogonal to the side wall is greater than the width of the first end portion.
