KenKenDoku

Looking for a puzzle game that uses more than simple matching or repetition? KenKenDoku turns every level into a compact logic exercise built around numbers and arithmetic. To solve a puzzle, you must place the correct digits into the grid while respecting row and column rules. But the real twist comes from the marked cages: each one has its own target value and mathematical operation. Solving the board means reading the structure carefully, comparing possibilities, and finding the only arrangement that fits everything together. The challenge grows naturally as you move forward. New boards require more planning, more cross-checking, and more precise thinking. That makes each completed level feel earned, especially when a difficult puzzle finally clicks into place. KenKenDoku offers number puzzles built around classic KenKen / Calcudoku logic, with arithmetic cages that use different operations and create a steady path from simpler boards to more advanced challenges. The game includes five difficulty ranges — Easy, Medium, Hard, Expert, and Extreme — along with simple controls, a bright casual presentation, and support for both English and Russian. KenKenDoku is a smart choice for players who enjoy calm puzzle solving, logical structure, and mathematical thinking in a light, colorful format.
