Solving the Puzzle

Solving the 4D Sudoku™ puzzle has little to do with mathematics. It involves nothing more than a certain step-by-step logic. No guesswork is needed. Basically, it´s a totally compelling and immensely satisfying process of manipulation and elimination.

Start with a strategy such as sides, rows or columns.

Strategy 1 - Sides

(In this example, they happen to be in counting order, though they can be in any order.

You could start by laying the cubes flat to complete one 3x3 section at a time.

Remember each side must include each of the numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9 with no repetitions or omissions.

Strategy 2 - Rows

Alternatively, you may choose to separate a side into three new rows.

This can make it easier to see the number on more than one side of each cube.

Strategy 3 - Columns

Building a series of 3-cube columns is another good strategy.

The method gives you the option of looking across all the rows.

The End Result

Regardless of which starting strategy you decide to use, the end result should look similar to this.

The set of 27 magnetic cubes must be arranged in such a way that each horizontal row, each vertical column and every possible 3x3 section of block contains each of the numbers 1 to 9...
...without duplication.

So far , so good ?

By now, you're thinking that you are incredibly clever... an Einstein... a Rubik... a GENIUS!

But, hold on! This is more than a three dimensional challenge!

This is 4D Sudoku™!

The puzzle within a puzzle!

Inside the Block

Whether sliced vertically

Every 3x3 section inside the block also contains each of the numbers from 1 to 9.

Or horizontally

At Sixes and Sevens?

Finally, what do you do when you've tried every way to solve your 4D Sudoku™ puzzle yet you still can't figure it out? Here's a clue...

Discover the Magic Square

On one 3x3 section of the puzzle, the three numbers in each row and column all add-up to the same total.

Okay! That does it! Now you are on your own - or better still why not share the fun with your friends and family?

Soon, everyone will be a 4d Sudoku™ expert!
