**Arthur Menu**:

I have discovered KenKen puzzles and enjoy them a lot but the more complex puzzles (9 x 9 grid) require a lot of time to solve. It would help if there were an app that would show all the possible integer solutions to an equation using only the integers 1 to 9.

For example, if I input the equation x+y+z=10,

the app would give the following results:

7,2,1

5,4,1

6,3,1

6,2,2

8,1,1

5,3,2

4,4,2

(Just doing the math in my head, may have missed a possible solution.)

If I input x*y*z=12,

the app would give:

6,2,1

4,3,1

Any takers? Or if such an app already exists, please point me to it.

Online version: KenKen and Kendoku calculator

If I input x*y*z=12,

the app would give:

6,2,1

4,3,1-Arthur Menu (April 14, 2018, 03:04 PM)

Thank you, 4WD! Perhaps you enjoy doing kenkens too!

As a side note, I recently experimented with the GO programming langauges and wrote a program to help make puzzles of a similar (but different form): For example, given the numbers [2, 3, 6, 15] find a mathematical expression that uses all of the numbers and reaches the target value of 7.

You can see my code here: https://www.donationcoder.com/forum/index.php?topic=39542.msg368923#msg368923

Never knew they existed until you mentioned them.

If you want to get into Python there's some code on StackOverflow that deals with finding multiplication cases, you may be able to contact the original poster and ask if he has posted his solutions for addition, subtraction, and division somewhere.

There's also a lot of software on GitHub.
