According to the abstract released by the Intellectual Property India: "[Problem] The present invention addresses the problem of realizing a fill-in-the-blank puzzle that is not found in the prior art and that enables both fill-in-the-blank play using numbers or symbols and drawing play. [Solution] Provided is a puzzle characterized in that: in a base figure configured from a plurality of equilateral triangles of the same size, when an arrangement in a direction in which the sides of the equilateral triangles overlap is referred to as a row, a specific range of numbers or symbols are entered in all equilateral triangles included in each row without duplication; the specific range is N or N+1, where N is the maximum number of equilateral triangles included in each row; and filling the equilateral triangles with a specific color for each number or symbol to be entered results in a pattern being displayed on the base figure. For example, in a fill-in-the-blank puzzle where ten numbers from 0 to 9 are entered in a base figure (101) configured from 42 equilateral triangles, an answer (202) can be obtained for a question (201) if the condition is to use black to fill in equilateral triangles containing odd numbers."
The patent application was internationally filed on Aug. 12, 2023, under International application No.PCT/JP2023/029384.
