Walker

Arrow Flow is another genre appearing in the arrows round of the Logic Puzzle Open 2025! It’s a Naoki Inaba invention, and like the name suggests, it has a very fun solving flow.

Rules: 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.

Interface Note: While not necessary for answer check, drawing borders between completed arrow regions (like in the example image) is very useful!
