A hexadecimal escape room
You're locked inside the abandoned Hexadecimal Research Lab. Five doors stand between you and freedom. Each lock speaks only in hex. Convert correctly to escape — but watch the clock.
Choose your challenge:
One hex digit = exactly 4 binary bits (a "nibble").
Read each nibble with the place values
8 4 2 1: e.g. 1011 = 8+2+1 = 11 = B.
A full byte uses 128 64 32 16 8 4 2 1.
