A twist on the anti-pair rule on a tessellation puzzle.

• This puzzle consists of two grids.
• Entropic anti-pairing: Cells on the same position on either grid have digits in different sets of low digits {123} middle digits {456} and high digits {789}.
• Each grid follows the tessellation rules:
  • Fill each cell with a digit from 1-9.
  • Cells sharing an edge can't have the same digit.
  • Each horizontal row and vertical column contains a non-repeating consecutive set of digits (like 23456) in any order.
• Cells joined by a black dot contain digits in a 1:2 ratio.
• A set of 3 cells around a white dot must contain a set of three different consecutive digits in any order.
• A set of 3 cells around a teal dot must contain digits in different residue classes modulo 3, i.e. in different sets from {147}, {258} and {369}.
• Not all possible dots are given.
