How to play
Convert each number to the base asked for. Answers are accepted with or without 0b/0x, in any case. Values grow from 4 to 12 bits as you score.
ShortcutsEach hex digit is exactly four binary digits (A = 1010, F = 1111), so binary ↔ hex is grouping, not arithmetic. Binary is shown in groups of four for that reason.
Lenient answersType with or without a 0b or 0x prefix, in upper or lower case, with spaces or underscores and leading zeros. The answer is accepted the moment it is right.
Growing valuesValues start as 4-bit (up to 15), become 8-bit after 5 correct and 12-bit after 12.
