The Randomness Game

Can you think like a computer?

How to Play:

  • Enter numbers between 0 and 255, one at a time
  • Try to be as RANDOM as possible!
  • Don't follow patterns (humans love patterns!)
  • Your sequence will be analyzed using NIST statistical tests
  • Can you beat the computer at its own game?
Pro tip: True randomness is harder than you think. Humans tend to avoid repetition and create patterns without realizing it!

How to generate random base64:

  • Linux/Mac: head -c 1000 /dev/urandom | base64
  • Or use any random byte generator and encode to base64
  • Minimum: 100 bytes (~133 base64 chars)
0 bytes (~0 bits)
