"Calcoolation" 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.
