Twin 4s
- Thermometers
- Arrows
The brief
Place 8 of the digits 1-9 into the sudoku grids. Digits cannot repeat in any column, row, or 2*2 box, and the left puzzle and right puzzle each have 4 unique digits.
Digits on an arrow sum to the digit in that arrows circle.
Digits increase from the bulb of the thermometer.
