As a fan of numbers and math, you are sure to love Calcudoku Light. So if you have already taken an interest in games such as Sudoku, you will be able to experience a new challenge here. Calcudoku Light is a game of thinking and computing. The playing field in Calcudoku Light also has some features in common with a Sudoku field. There are small squares, in which you have to enter numbers. In the first level, which is also the easiest level, you need to write in only the numbers from 1 to 4. As in the game of Sudoku, each row from top to bottom and from left to right has to also contain all numbers from 1 to 4 just once here. In some of the boxes on the playing field, a number has been entered already. This is the result of the equation that you have to enter into the game. At the upper right corner of the playing field, you see the equation sign, which you have to use for this level. The boxes in the playing field are always divided into groups of two boxes. In these two boxes, you must now enter the numbers that solve the equation. So if for example, a 7 is in a box of Calcudoku Light, you must enter a 4 and a 3 in the two boxes. Where and how you have to place the numbers will become evident to you over the course of the game.
