SUDOKUPAD

each row, column, and region includes digits 1-9 once and only once.

• offset clones: each digit in a blue-shaded region A is equal to the equivalent digit (the digit in the same relative position) in the other region A plus N (modulo 9: 6+4 = 1), where N is some constant. digits do not repeat within a region.
• the same is true for green-shaded regions B.
• thermometers: digits along a thick grey line strictly increase moving away from the bulb.
