Mainarizumu

Mainarizumu is played on a square grid, typically 7x7 or smaller, with two kinds of clues: a greater-than or less-than sign connecting two adjacent squares, or a circled digit connecting two adjacent squares. The solver is to enter a digit, between one and the grid width/height, into every square so that:

• No digit is repeated in any row or column (much like in Sudoku puzzles).[1]
• If two squares are connected by a greater-than or less-than sign, then the digits in those squares must obey that inequality.[1]
• If two squares are connected by a circled digit, then the digits in those squares must differ by exactly that amount.[1]
