Normal Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.

The Thanos rule applies. Starting with R9C4 clockwise along the bronze line there are cell pairs. The second cell is always half as big as the first one. So if R9C4 is 8 then R8C4 is 4, and a new pair starts with R7C4. And just to be clear: R9C5's pair is R9C4, so it is both the start and the end of the line.

Arrow Sudoku rules apply. Digits along an arrow in the grid must sum to the digit in its circle. Digits may repeat along the arrows.

The infinity stones (colored circles) are odd numbers.

The puzzle is also available online.
