## What is Kakurasu (Sudoku like Japanese Puzzle Game)?

Kakurasu is a fun Japanese Puzzle Game.   A Sudoku variant.  This game is a little hard to understand in the beginning.  But once you 'get it' you will have fun!  Trust me!

I recommend giving it a try.  The rules are listed below....

RULES:
1. Find all of the Blue squares such that all of the totals match the clues.
2. The clues are on the right and across the bottom and are the totals for the respective rows and columns.
3. The numbers across the top and on the left are the values for each of the squares.

E.g. The first square in a row or column is worth 1, the second 2, the third 3, and so on.
Marking a square in Blue will add that square's value to both the row's total and the column's total.

## Key features

- Logic puzzle gameplay
- Sudoku variant
- Row and column totaling mechanics
- Unique blue square placement
- Challenging for new players
