Real Kakuro 20×20

## Description

_Real Kakuro 20x20_ is based on a puzzle called Kakuro. The puzzle is rather
like a crossword puzzle but uses added numbers. A box is show with a \ in the
middle. The number on the bottom left is for the column directly below. The
number of the top right is for the row directly right. Each row or column uses
the numbers 1 through 9 but each uses each number only one time and must add
up to the shown number clue. This version is much the same as Real Kakuro but
this time, the game board is twenty by twenty squares rather than ten by ten.
The game has ads but they can be disabled with an in-game purchase.
