Step-by-step walkthrough

Every step below follows from the rules alone, with no guessing. Try the puzzle first and use the walkthrough when you get stuck.

1. Step 1 of 13

   Start in the bottom-right corner. The cell at row 10, column 10 has only two usable neighbors, so a path must pass straight through it, and Red's lower dot is one of them. Red steps into the corner and climbs the right edge to row 8.

2. Step 2 of 13

   Thinking ahead, Blue's upper dot at row 1, column 4 can go left or right. If it goes left, a few forced moves later Blue at row 1, column 3 has no good move, since going down or left would box Pink in. So Blue goes right one.

3. Step 3 of 13

   Blue has another choice at row 1, column 5. Running right along the top fails, because a few moves later Blue at row 1, column 8 would cut Red off from its partner whichever way it turned. So Blue drops two cells, right above its lower dot. That squeezes the cell at row 1, column 6, so Red climbs from its upper dot into the top row and heads right to column 8.

4. Step 4 of 13

   Green's dot at row 2, column 4 could go left or down. Going left would box Orange in with nowhere to go, so Green goes down one.

5. Step 5 of 13

   Red at row 1, column 8 can't drop down without being cut off from its partner, so it runs to the top-right corner and down the whole right edge to join its lower half. A chain of forced moves follows on the right. Green snakes down from its dot at row 2, column 9 to row 6, column 6, and Brown winds down to row 7, column 7. Purple, Blue and Lime connect, and Yellow steps left from its dot and drops into the bottom row.

6. Step 6 of 13

   Green now stands at row 6, column 6. Dropping down would seal off a single cell that no color can fill, so Green moves left one.

7. Step 7 of 13

   The same thing happens at row 6, column 5. Going down would leave a one-cell pocket that nobody can finish, so Green steps left again.

8. Step 8 of 13

   At row 6, column 4, Green could keep going left. That would cut Pink off from its partner, so Green turns up instead.

9. Step 9 of 13

   Green faces the same choice at row 5, column 4, and going left still cuts Pink off. Green climbs one more cell, which brings it right under its other half at row 3, column 4.

10. Step 10 of 13

    Brown at row 7, column 7 could turn left, but that would seal a two-cell pocket that no color can finish. So Brown drops two cells and connects to its dot at row 9, column 6. Yellow then has only one open side and runs left along the bottom row to column 5. The cell at row 7, column 6 now has only two usable neighbors, so Cyan climbs into it from its dot at row 8, column 6 and turns left to row 7, column 5.

11. Step 11 of 13

    Pink's lower dot at row 9, column 3 could go down, but that would cut Gray off from its partner. So Pink steps left one.

12. Step 12 of 13

    Cyan, at row 7, column 5, could go down. That seals off a one-cell pocket, so Cyan connects to its dot at row 7, column 4 instead.

13. Step 13 of 13

    Yellow at row 10, column 5 can't keep going left without cutting Gray off, so it climbs to row 8 and turns left into its dot at row 8, column 3. Gray drops into the bottom row, follows it to the corner and climbs the left edge to its partner at row 6, column 2. Orange climbs column 2 to its upper dot, and Green's ends join. Pink climbs columns 2 and 3 to the top row and loops through the top-left corner down to its dot at row 4, column 1.
