How to play

  • Connect each pair of matching numbers with a single continuous line of horizontal and vertical steps.
  • Lines cannot cross each other, branch, or share any cells.
  • Lines start and end at the numbers, and cannot pass through another number.
  • Every cell on the board must be covered by a line.

Connecting Matching Numbers

Connect each pair of matching numbers with a single continuous line of horizontal and vertical steps. Lines must never cross each other.

1122
✓ Correct Matching 1s and 2s connected by continuous, non-crossing pastel lines through adjacent cells.
1122
✗ Wrong Crossing lines: paths cannot intersect or share any grid cell. Lines must go around each other.
1122
✗ Wrong Mismatched connection: line connects number 1 to number 2. Only matching numbers may be paired.

Lines and Endpoints

Numbers are endpoints only. Lines cannot branch, fork into T-junctions, or pass through another number.

1122
✓ Correct Lines start and end at the numbers. They turn cleanly through empty cells without branching.
11
✗ Wrong Branching line: a line splits or forks into multiple directions (T-junction). Branches are not allowed.
1122
✗ Wrong Passing through a number: lines cannot run through another number on their way to their target.
