CalcuDoku takes classic Sudoku and adds a math-based twist that’ll stretch your logic skills. You’ll see bold “cages” on the grid, each with an operator—addition, subtraction, multiplication, or division—and a target result. Just like Sudoku, you can’t repeat numbers in any row or column. But here’s the catch: the digits you place in each cage must combine (using that operator) to match the given total. It sounds tricky at first, but a good strategy is to start small—look for cages with only one or two squares to lock in obvious numbers. That often gives you the foothold you need to figure out the rest. If you’re up for an extra challenge, beat the clock to set a personal record. Whether you’re a die-hard Sudoku fan or simply love logical puzzles, CalcuDoku is sure to keep your brain firing on all cylinders..
