About the game
Chess meets sudoku: two cells a knight's move apart (two steps one way, one to the side) never hold the same number. Nothing extra is drawn; the rule is in your head.
Rules
Fill the grid so that every row, every column and every 3×3 box holds each number from 1 to 9 exactly once.
Two cells a chess knight's move apart (two steps in one direction and one to the side) never hold the same number.
Every puzzle has exactly one solution, so it can always be found by reasoning, without guessing. A number that breaks a rule turns red.
