This sudoku is a collaboration between myself and The Pi Guy. Hope you enjoy it! :)

Sudoku: Put the digits 1-9 once each into every row, column and 3 by 3 box.

Circle Sums: The digits in the 4 cells surrounding a circle, sum to the number in the circle.

Sum Thermometers: The sums of the 2 by 2 areas along each sum thermometer must strictly increase from the bulb to the tip.

Modular Lines: Each set of 3 cells along a solid teal line must consist of a digit with remainder 1 (147), a digit with remainder 2 (258) and a digit with remainder 0 (369) when divided by 3.

Entropic Lines & Global Entropy: Each set of 3 cells along a hollow gold line must consist of a low digit (123), a middle digit (456) and a high digit (789). In addition, each 2 by 2 area in the grid must contain at least one low, one middle and one high digit.

This is probably 4.5 stars.. this isnt brutally tough global entropy, there is just quite a lot going on with the interactions between clues.

Do give it a go!
