Swapdoku

Swapdoku is a Sudoku-like number game you solve by swapping.

Click or drag two numbers to switch their positions.

Each row and column must form a straight, in any order. For example: 4,3,2,1 or 3,5,4,6.

Green tiles are in the correct position.

Gray tiles with arrows are clues and show the sum of the numbers they point to.
