ArrowLoop: Arrow Logic Puzzle

Connect the dots into one closed loop that travels the way every arrow points.
ArrowLoop is a logic puzzle with a single rule.

HOW TO PLAY
• Tap between two dots to draw a line, or drag to keep drawing.
• Edges with arrows are drawn for you. Each arrow says: this edge is traveled in this direction.
• Join the lines into one closed loop. A dot can hold at most two lines, so the loop never branches or crosses.
• Travel around your loop. If you move the same way as every arrow, the puzzle is solved.
• When you know an edge is not used, press and hold to mark it with an X.

NEW TO THE GAME?
You start with three tiny practice boards: draw a line, close a loop, place an X. Then the first eight Normal puzzles introduce arrows and loops on a 3×3 board. If you pause, a hand shows you what to do next, and you can replay the lesson from Settings at any time.

WHAT MAKES IT TICK
A closed shape is only half the answer. The loop also has to run the right way for every arrow. One arrow decides where a line must go, and that line has to agree with the next arrow along the way.
For example, the dot at the end of an arrow line always needs one more line, because the loop never stops. If there is only one way to go, that line is settled.
Small certainties like this add up until the whole loop appears. Every puzzle has exactly one answer, so you can reason your way to the last line.
