Opdoku = Calcudoku + Mathdoku 5.1

Opdoku offers a free-to-use platform with an intuitive interface, devoid of advertisements or in-app purchases. Delving into its mechanics, Opdoku abides by the classic Sudoku rule: each digit must only occur once in each row and column.

Going beyond traditional Sudoku, Opdoku introduces an interesting twist to the gameplay. Players must work within groups of digits, each assigned a mathematical operation and a specific result. The challenge lies in ensuring that all digits within the group contribute to reaching the desired outcome through the designated operation.

Opdoku distinguishes itself from similar puzzle games by incorporating three key enhancements:

• Players can opt for additional mathematical operations like minimum and maximum in puzzles, heightening the game's complexity and variety.
• Delving deeper into problem-solving, players may encounter puzzles where the mathematical operation is unknown, offering multiple potential solutions to reach a specific result.
• For the most ardent puzzle enthusiasts, there are challenges where not all group results are provided, catering to those seeking the ultimate test of logic and deduction.

All Opdoku puzzles are meticulously crafted to ensure a unique solution. With an automatic generator at its core, the game offers an endless array of puzzles ranging from elementary 3x3 grids to mind-boggling 6x6 grids with scarce clues.
