CLASSROOM RULES
Puzzles That Make Math Fun ™
HOW TO PLAY KENKEN®
1. Fill in each square with a single number. In a 3x3 grid, use the numbers 1
through 3. In a 4x4 grid, use the numbers 1 through 4. In a 5x5 grid, use
the numbers 1 through 5…and so on.
2. Do not repeat numbers in any individual row or column. For example, in a
3x3 grid, each column and each row should be filled in with the numbers
1, 2, and 3, with no duplication.
3. Each heavily outlined set of squares is called a “cage.” The numbers in
each cage must combine (in any order) to produce the target number
indicated in the top corner by using the mathematical operation next to
the target number.
4. A number may be repeated within a cage as long as it is not in the same
row or column.
HINTS
1. First fill in single box cages, called “freebies,” with the number in the top
left corner.
2. Note the candidates (all possible numbers for each square) for each
remaining square and then determine the correct numbers by math,
logic, and process of elimination.
3. Each puzzle has one unique solution.
