About the game
Arrows start from circles. The numbers along an arrow add up to the number in its circle: a bit of arithmetic woven into the classic rules.
Rules
Fill the grid so that every row, every column and every 3×3 box holds each number from 1 to 9 exactly once.
The numbers along an arrow add up to the number in its circle. A number may repeat on an arrow if rows, columns and boxes allow it.
Every puzzle has exactly one solution, so it can always be found by reasoning, without guessing. A number that breaks a rule turns red.
