Another great tutorial that may help you:

Also have a look at my solution that I used

scirra.com/forum/generate-unique-times-tables-questions-array_topic65058.html

It doesn't do the shuffle but it would be pretty easy to implement.

Just loop through the array use a temp variable to hold a value so you can swap two array elements.

kittiewan's solution theoretically can takes forever. Fisher Yates is a O(n) solution. So it guarantees a maximum n times loop.
