Math-based, sudoku-like game

This is a puzzle game that at first looks like the popular Sudoku. Just like in Sudoku, you have an N x N matrix, where the digits 1 through N must be placed in each column and in each row without repetition. The difference lies in the fact that there are blocks of cells, named "cages", where specific operations involving the numbers in the cells must satisfy the specific result displayed in the cage. Here we use "Naked Pairs/Naked Triplets" strategy.

Playing With Candidates

Through the menu where you can turn on/off the candidate digits. This in order to make notes about which numbers can or can't be placed in cells. Notice that, when you play with candidates, the interface changes a little bit.

The Naked Pairs

Before getting a random number for a cell, you should always look for "naked pairs". Naked pairs mean that in some row or column, there are two cells with two possible values. The reason for spotting naked pairs is simple: since these two cells can hold only these two digits, no other cells in that row will have "3" or "4". Thus we can remove them from the possible digits.
