Arofuro ("Arrow Flow") is a logic puzzle invented by Naoki Inaba (Japan). A rectangular or square grid contains numbers in some cells. The aim is to place arrows pointing in four directions in each empty cell.
- The same arrows cannot be placed in adjacent cells.
- Starting with any cell with an arrow, following the arrows from cell to cell, a cell with a number can be reached.
- A cell with a number indicates a total number of arrows that leads to this cell.
