Normal sudoku rules apply.

Any two cells separated by a knight's move (in chess) cannot contain the same digit.

Digits on thermos must increase from the bulb.

Additionally, cells a knight's move away from a thermo bulb cannot contain any of the digits on that thermo. (see example below)

Example

Thermo A and B is correct and can see each other even tho both have an 3 and 4 in common, as neither 3 or 4 is in the bulb

Thermo D would be able to see thermo C bulb, but thermo C bulb can not see thermo D bulb, as the 4 in thermo C will see the 4 in thermo D with knight's move

I hope the rules are clear, if not, please tell me.
