About this arcade

When you're reading a MAC address or a memory dump in hex, sometimes you need the actual bit pattern underneath — fast, not eventually. This timed round builds exactly that translation speed.

Each round hands you a hex value and starts the clock. Same digit-by-digit expansion as calm practice, now under pressure.

Key terms

Hexadecimal
Hex
A base-16 number system using digits 0–9 and letters A–F; each hex digit maps to exactly 4 bits, making it a compact shorthand for representing binary data.
Binary
The base-2 number system that uses only the digits 0 and 1; the native language of digital computers, which store and process data as electrical on/off states.
Nibble
A group of exactly 4 bits, equivalent to one hexadecimal digit; two nibbles make up one byte.
Bit
Short for binary digit, the smallest unit of data in computing, holding a single value of 0 or 1; all digital information is ultimately composed of bits.
