This is my second puzzle, and the second hyperbolic sudoku on this site. This puzzle really involves some mechanics that you may not encounter on “flat” puzzles. If you’re not familiar with hyperbolic sudoku, please feel free to try this one which is very easy.

Rules:

(Hyperbolic Sudoku) Fill the grid with digits 1-9 with no repeats in any row or box. A “box” is a 3x3 square and a “row” is 6-cells-long and slightly folded at box edges.

The cyan outer loop is a region sum loop: within each box, digits sum to the same total. The yellow middle loop is entropic: any 3 consecutive digits must contain a low digit (123), a middle digit (456) and a high digit (789). The red inner loop is a whisper loop: orthogonally adjacent digits must have a difference of at least 3.

A digit in a circle indicates how many circles contain that digit. Black dots separate digits with a 1:2 ratio.
