Numberlink Connection Puzzle: player questions
Do I need to fill the whole board?
Yes. All endpoint pairs must connect and every square must belong to exactly one path.
Can paths cross?
No. Each square can belong to only one path.
Can I move diagonally?
No. Each step must share an edge with the previous square.
What if I choose the wrong route?
Drag backward along your path to erase its tail, clear that color, or use Undo.
Can I begin at either endpoint?
Yes. Both directions represent the same pair.
May a path pass through another endpoint?
No. Other pairs’ endpoint squares are reserved for their own paths.
Is there always only one answer?
This edition accepts any complete valid covering. Generated boards have at least one checked construction; uniqueness is not promised.
How do I draw on a phone?
Touch an endpoint and drag through neighboring cells. You can also select an endpoint and tap the next adjacent square.
Why do the endpoints have numbers too?
Numbers identify matching pairs without relying only on color. This helps when colors look similar.
How do I change the board size?
Choose easy for 5×5, medium for 6×6 or hard for 7×7. Each level uses a different seeded layout.
