Kakuro (also known as Cross sums) is a mathematical puzzle game which can be solved using logic. Kakuro grid has 3 types of cells. 1. Blank cells which are not used in the game. 2. Hint cells which are divided using a diagonal line. The two halves can have numbers in one or both. Right halve contains a number which is sum of associated cells to the right (horizontally). Left halve contains a number which is sum of associated cells below it (vertically). 3. Input cells which can have a digit from 1 to 9 such that no digit is duplicated and sum of numbers in a group matches the hint associated with it.
