This is a small taster puzzle to try out the idea for a new sudoku variant ruleset. In the 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.

- Each row column and 2x2 box must contain the digits 1-4.
- 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, if a row contains the digits 4,3,2,1 in that order, the sum could be 325(4+321), 64(43+21) or 433(432+1).
