How to play

Mark every number in the grid as a debit or a credit so that in each row and each column the debits add up to the same total as the credits. Some cells come already posted and can't be changed, the margins show each line's running totals against its target, and every puzzle has exactly 1 solution you can reach by logic. Difficulty climbs from Monday to Saturday, and variant days add a rule, such as writing off exactly 1 cell in every row and column so its amount doesn't count.
