Magic Square Puzzle


The objective of this challenge is to find sets of four numbers in this magic square that add up to the magic total of 34.

You can click on the numbers to select them. If you make a mistake you can click on a number to deselect it.

Find 14 different ways of making 34 will earn you a level 1 trophy.

Find 21 different ways to earn a level 2 trophy.

Find 28 different ways to earn a level 3 trophy.

Find 35 different ways to earn a level 4 trophy.

Find 42 different ways to earn a level 5 trophy etc.

Sounds easy? Be careful you do not select a group of four numbers you have already found. Duplicates and incorrect totals will send you back to the beginning!

There is a solution to this puzzle but it is only available to those who have a Transum Subscription.

"When I've found all 86 sets that add up to 34, the puzzle invites me to continue but if I submit another it will either be a repeat of one already found or add up to a different total. So when I've found all 86, shouldn't the puzzle confirm that I've found all of them? (There are 86, aren't there?)."

"Richard, congratulations, you are correct, there are 86 ways altogether. The reason the program didn’t tell you that you had found them all was to test if you knew there were no more. The action to take at that point is to claim your trophy for level 11.

Many other Transum activities ask you to find all the arrangements, combinations or permutations of something and the system confirms when you have finished. I thought this activity should be different and allow students to find their own way of being certain that they have found all possibilities.

Incidentally, only four of the trophies in the last 1000 claimed (at the time of writing) were for level 11.

Thanks so much for taking the time to comment on this activity. "

"We use your puzzle as inspiration to propose this task to students 8 years and older: Magico De Durer We thought that perhaps you would be interested in getting to know it along with another task in which we changed the magical square of Dürer for the one that appears on one of the facades of the "Sagrada Familia" in Barcelona, our city: Magico De La Sagrada Familia."
