CancelWise

A grid of positive and negative numbers is given with a target sum beside every row and column. Clicking a cell cancels it and removes its value from the totals, and the puzzle is solved when every sum turns green. Four difficulty levels from easy to expert are available, and earlier dates can be selected with arrows.
