Further to my recent series of Power BI based games, I thought for this article I would build a version of the popular children’s game, Hangman. To win the game, you need to guess a hidden word letter by letter, with the user having a number of “chances” with each wrong guess bringing you closer Read more about Fun with DAX – Mission Impossible[…]

Excel has a ROMAN() function so I thought it was about time to share one approach to converting decimal numbers to Roman. I can feel a collective Read more about Quick DAX : Convert to Roman Numerials[…]

Once you have the number in binary format, you can apply logical operations between numbers to Read more about Quick DAX : Convert number to binary (and back)[…]

A big thanks to my good friend Tom Martins over at minceddata for giving me the idea. The end result Read more about Fun with DAX – Sudoku[…]
A not so obvious use of the recently added GENERATESERIES function to use it to generate time buckets. The more common use of this function is to generate series of numbers, but it works just as well with Time based data. Say you want to create a data table with rows that represent time periods.

I thought it might be fun to try something a little different with this blog and use a combination of bookmarks with a little DAX magic to come up with a game that plays a hand of Blackjack. Power BI and DAX are not the ideal engine to build a game of Blackjack with, but Read more about Fun with DAX – Blackjack Game[…]
