TIP 1: USE LOGIC, NOT GUESSWORK
Kenken puzzles are like Sudoku puzzles in this respect. If you make a mistake, it’s never apparent immediately; when you do discover it, it’s almost always impossible to retrace your steps and start again. Therefore, use elimination and only fill in a number if you are 100% sure it’s correct. There is sometimes a cage with only one cell in the simple puzzles, so only one number can go in. There, you’ve started.
TIP 2: WRITE DOWN THE NUMBERS YOU CAN ONLY USE
So if, for example, you are solving a 4 x 4, write the numbers 1 through 4 somewhere near the grid. It’s good always to have the different number combinations and their relationships in your mind. This is easier if you can see the numbers.
TIP 3: WRITE IN CANDIDATES
Kenken puzzles are also like Sudoku puzzles in that writing in candidates in the cells is a good idea. Candidates are lists of numbers that could go in a particular cell and can be penciled in the corner. You will find that you can narrow these down to one candidate later on as you start solving.
TIP 4: USE SCANNING TO ELIMINATE CANDIDATES
With Kenken puzzles, the number can only appear once in any row or column. So, if you find a number, it’s eliminated from the row and column that intersects that particular cell. Numbers can be, therefore, eliminated from candidate lists when cells are solved using this logic.
TIP 5: LOOK FOR ROWS AND COLUMNS THAT ARE ALMOST FINISHED
If a row or column has only one cell left unsolved, then as you cannot repeat a number, only one can go in it. For example, if you had a row or column of 5 with the numbers 2, 1, 5, and 3 already filled in, the last unfilled cell must contain a 4.
TIP 6: USE MATHS
Remember that Kenken puzzles use math, which can further eliminate candidates. For example, if you are solving a six-by-six grid and have a cage with a sum equal to 11, then only two numbers can go in, 6 and 5, so we can put them as the only candidates. Always look for cages like this where only a few numbers can go in.
TIP 7: LOOK FOR PAIRS AND TRIPLES
The above are examples of pairs, and yet again, this makes Kenken puzzles similar to Sudoku ones. So, if you have two cells in a row or column where only two numbers can go, those cells can be eliminated from other candidate lists in that row or column.
TIP 8: BE FLEXIBLE IN YOUR THINKING
If you get stuck, switch techniques, i.e., go from looking for pairs and triples to scanning. When we get stuck in puzzles, it’s usually because we’ve missed something, and changing approaches can generally uncover something we have overlooked.
TIP 9: COME BACK TO IT LATER
Even the best solvers get stuck once in a while. If you are stuck, save what you have done and return to it again. With a fresh mind, you will spot something that you missed before.
