The files here are puzzles for a variant of Sudoku I like to call "Prosperity 7". In this Sudoku variant, the board is only 7x7, and only the numbers from 1 to 7 are used. Neither 8 nor 9 are ever placed on this board.

The object of this puzzle is to place the numbers 1 through 7 in the blank spaces such that:

  • Each row only has one instance of each number between 1 and 7. In other words, no number is duplicated in a given row.
  • Each column only has one instance of each number between 1 and 7. In other words, no number is duplicated in a given column.
  • Each of the seven-square shapes bordered by thick lines have all of the numbers between 1 and 7 precisely once.
Also included is the code used to generate the puzzles.
