Pretty simple when you can just check the last bit for odd vs even, but otherwise fun enough for a binary guessing game

its simple, but not that simple... As you advance through later levels you are prompted with AND and OR operations.

Ah took a while, but I can do binary under pressure! Quite fun. :D

I got everything correct except XOR, which i can't do fast at all. ::Goes to write some tables::

Yeah I had hard time with XOR as well.

I learned I can even do hexadecimal under pressure, with no warning!

I took me 4 or 5 tries, the AND ones were hard for me
