How to Play
MathDoku puzzles exercise both logical deduction and mental arithmetic in a compact grid format. Each cage's target and operation constrain which digits can appear inside it, and the Latin-square rule — no repeats in any row or column — further restricts placements. Smaller cages with division or subtraction are especially powerful because they have very few valid fills: a two-cell subtraction cage with target one on a six-by-six grid can only hold consecutive digit pairs. Solving efficiently requires balancing cage arithmetic with row-column elimination. Each puzzle on this page has exactly one valid solution. Before placing digits, note the grid size because it determines the digit range — a four-by-four grid uses digits one through four, while a six-by-six grid uses one through six.
What This Page Is
MathDoku, also known as KenKen or Calcudoku, is an arithmetic logic puzzle on an N-by-N grid divided into groups of cells called cages. Each cage displays a target number and an arithmetic operation, and the solver must fill digits so that applying the operation to the cage's digits produces the target.
Goal
Place digits from one through N in every cell of the grid so that no digit repeats in any row or column and every cage's digits combine under its specified operation to produce the cage's target number.
- Note the grid size N to determine the valid digit range from one through N for every cell in the puzzle.
- Examine single-cell cages first — these are freebies with the target digit placed directly since no operation applies.
- For each multi-cell cage, list all digit combinations that produce the target under the given operation without repeating a digit if the cage spans a single row or column.
- Cross-reference cage candidate lists with row and column constraints to eliminate impossible digits from shared positions.
- Fill confirmed cells and propagate eliminations across intersecting rows, columns, and cages until every cell is determined.
Rules
- Each row and each column must contain every digit from one through N exactly once, forming a valid Latin square.
- The digits within each cage must produce the cage's target number when combined using the specified arithmetic operation in any order.
Tip
Subtraction and division cages in a two-cell group are the most restrictive — solve these first because they typically admit only one or two digit pairs, anchoring large sections of the grid early.
