How to Play Mini Arrow Sudoku
Fill the 6x6 grid so that every row, every column, and every 2x3 box contains the digits 1 through 6 exactly once. Then add the arrow rule.
- Path sums to the circle: The digits along an arrow's path add up to the digit in its circled cell.
- The circle is largest: Because it holds the sum, the circled cell is always the biggest digit on its arrow — a two-cell path already needs a circle of at least 3.
- Repeats are allowed: A digit may repeat along a path if normal Sudoku rules permit it. Only the total has to match.
- Conflict checking: If a path already overshoots its circle, the arrow's filled cells are ringed in amber immediately.

Frequently Asked Questions
What is Mini Arrow Sudoku?

The 6x6 is quicker and the small sums are easier to read — the ideal way to get comfortable with path sums before the full grid.
