The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random.

Feel free to share your theories on the best random number generator designs below, or send your best builds straight to the tipsline. Randomly, of course!

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.
