Free NO-OP Samples
NO-OP puzzles are normal KenKen puzzles with one key difference: the operation symbols next to the target numbers have been omitted. The same basic KenKen rules are in effect, but you must also figure out which mathematical operations are to be used in each cage.
Hint: Cages with 3 or more boxes must be addition or multiplication.
