Sudoku is Outside the Box by Jrosas, App variant is OTHER


Normal sudoku rules apply. Digits on a thermometer increase away from the bulb end. A digit in a circle indicates the number of circles that contain the digit. A digit in the center cell of an bold outlined 3x3 box is the sum of all circled digits in cells outside the box adjacent to the box, including diagonally.
