About this arcade

This is the same increment you practiced in the calm drill, now timed and scored. The math doesn't change — what changes is whether you can roll 9 to A and F over to the next place without hesitating.

Each round throws a fresh hex value at you and starts the clock. Read it, add one, type the next value in hex. Your streak and your time per question both feed your score, so getting it right matters, but getting it right quickly matters too.
