Magnetic block toy

A magnetic block toy that is magnetically coupled to a coupling target, the magnetic block toy comprising:

• a block body having, on outer surfaces thereof, a coupling section that is a plane section capable of magnetically coupling to the coupling target and a non-coupling section that is a plane section incapable of magnetically coupling to the coupling target;
• and
• a disk magnet provided inside the coupling section in the block body and having a north-pole portion and a south-pole portion aligned along a circumferential direction thereof, wherein
• the block body includes a magnet-holding portion in which the disk magnet is arranged along the coupling section and held in a circumferentially rotatable manner,
• length of at least one side of the block body is equal to or longer than 30 millimeters and shorter than 40 millimeters,
• only the coupling section out of the coupling section and the non-coupling section is provided with a predetermined label indicative of being capable of coupling to the coupling target,
• in the coupling section, a stepped portion is formed so that at least part of an outer-edge portion of the coupling section protrudes.
