This is a new sudoku variant puzzle created for the June 2021 monthly puzzle prompt in the CtC fan discord server. In this puzzle you must imagine a plus sign between two of the digits in a row or column. This results in two separate numbers, one either side of the plus sign. the sum of the two numbers must add up to a number given by a clue outside the grid.
Find the ➕ No. 1
- Each row column and 3x3 box must contain the digits 1-9.
- Each row or column with a clue outside the grid needs to be split into two parts with a + sign between them. The value outside the grid is the result of adding together the two numbers resulting when read left to right in the row or top to bottom in the column. For example, the digits 1,2,3,4,5,6,7,8,9 in that order might give a sum of 1234656 (1234567+89), 124245(123456+789), 23456790(1+23456789) etc...
