Game CalcuDoku online

In the CalcuDoku game, we have prepared a really unusual and exciting puzzle game for you. It is based on Sudoku, but with additions that make the task a little more difficult. According to the rules, you must fill in the cells with numbers that should not be repeated vertically or horizontally. But at the same time, you need to take into account the numbers that are located in the upper left corners of the cells, which are circled with a bold line. There are mathematical signs next to them, which means that the number you place in the cell will be different. We wish you good luck with CalcuDoku.
