## Four-Way Loop

(Eingestellt am 25. März 2022, 08:00 Uhr von SudokuExplorer)

Draw a single loop in the 16x16 grid, satisfying a different rule in each quadrant.

1. Masyu
The loop passes through all circled cells in the 1st quadrant.
In cells with a black circle, the loop makes a 90° turn and goes straight through the cells before and after. In cells with a white circle, the loop goes straight through and makes a 90° turn in at least one of the cells before or after.
Not all circled cells are necessarily given.

2. Tapa-Like Loop (Full)
The loop passes through all unclued cells in the 2nd quadrant.
A clue gives the number of surrounding cells continuously passed through by the loop.
"?" can represent any positive integer.
For an example, see Dandelo's puzzle

3. Simple Loop

4. Mid-Loop
The loop passes through all black dots in the 4th quadrant.
Each black circle is the midpoint of a horizontal/vertical line segment of the loop.
Not all black dots are necessarily given.

You can try this on Penpa+. Enjoy!

Lösungscode: For each row, enter the length of the longest horizontal loop segment.

Can the loop enter and exit each quadrant any number of times?
