1. 19: Digits in the first column indicate in which column the digit 1 is placed in the respective row. Digits in the ninth column indicate in which column the digit 9 is placed in the respective row.

2. Standard arrows: digits along an arrow sum to the digit in the arrow's circle.

3. Standard clones: 3 cell, purple colored areas of the grid must contain the same digits in the same positions.

4. Magic squares: boxes 1 and 9 are magic squares in which each row, column, and diagonal sums to the same number.
