Normal Sudoku rules apply.
Cells of the same color are connected. That means that they have to contain the same digit. Cells of different colors can either contain the same or different digits.
Two cells that are separated by a white dot contain consecutive digits. If two cells are separated by a black dot, the ratio between the digits in those two cells is 2:1. Not all possible dots are given.
Thermometers in the grid contain digits that increase from the bulb end.
Additionally, the digits along lines that are not part of a thermometer form palindromes, i.e. they read the same from both directions along the line.
Two cages are marked in the grid. The inequality sign between the cages shows which cage has the larger sum.
