Instructions

Your goal is to remove numbers from the grid so that the remaining numbers in each row or column add up to the numbers next to that row or column. Click to remove or turn off a number, or click a removed number to add it back in. You can also click and hold a number to "lock" it on. If you know that a particular number needs to be used, you can lock it on to make solving the rest of the puzzle easier.
