This game will remind you of Sudoku but it's more original. It has more mathematical operations that you have to do, so the game will make you do calculations and think to solve the challenge.
You have to fill papers with numbers based on the numbers that are found in the main paper. So the 3X3 is filled with the numbers 1 to 3. Remember, one of the game important rules is that the columns and rows must have different numbers.
Shapes with bold lines are known as cages. The numbers on them must be combining together to produce specific number. The specific number must be calculated by maths operations (+, -, x, ). When all the cages have been completed and there are no repeated numbers then the puzzle is solved.
