The present invention provides a character and toys that can learn the correct orientation naturally. A combination of plate-shaped pieces toy has a shape relative to the square is equal to the length of the four sides. Characters are denoted on one surface of the plate-like piece. The first side L1 of the plate-shaped pieces are formed a first recess R1 is the fourth side L4, and so as to be a figure of the first line-symmetrical to the diagonal line DL1, based on the plate-shaped pieces in, it is formed a second recess R2 is, in the second side L2, a position facing the second recess R2, the first convex portion P1 of a shape that fits in the second concave portion R2 is formed and, the third side L3, and so that the shapes of the first linear symmetry diagonal DL1 based on the plate-shaped piece, the second convex portions P2 are formed. .BACKGROUND 9
