Here's a new commit I'm quite proud about.

You can now change the Bingo number style.
For those who preferred the bold black numbers from the original Master Board, you're in luck. In Themes, there's a new setting that brings back the classic Bingo number look.

Bingo Master Board now crypto-randomly draws Bingo balls. Hear me out.
It turns out there are different ways to generate seemingly random numbers. PowerPoint VBA's Randomize/rnd and JavaScript's math.random() can generate numbers efficiently, but they are NOT cryptographically secure. This means that someone skilled enough could predict what numbers will be generated.
For a Bingo game with tangible prizes, this poses a problem.
Enter crypto-random, a method to generate random numbers using the Web crypto API. Along with using a more advanced algorithm, crypto-random bases its randomness on your computer's voltage, cursor movements, keyboard timings, and much more. This makes guessing the next random numbers incredibly difficult, if not impossible.
I hope this change helps you feel more comfortable using Bingo Master Board in a competitive environment. Remember that you can check the new code on GitHub to your satisfaction.
For reference, VBA's Randomize/rnd uses a linear congruential generator, and JavaScript's math.random() uses XorShift128+ in most browsers. Feel free to research the pros and cons of these algorithms if you're interested.
