Arrowku: Daily Arrow Logic

Arrowku is a calm, clever logic puzzle built on two simple rules.

FOUR DIRECTIONS IN EVERY ROW
Fill each row of the 5x5 board with up, right, down and left, exactly once each.

MAKE THE NUMBERS COUNT
Every row has one brass beacon. Its number is how many arrows point straight at it along its row and column, from any distance. Other arrows never block the way. When a beacon is satisfied it lights up.

Every puzzle has exactly one solution, and you can always reach it by reasoning, never by guessing.
