Binary Practice

Introduction to the tool and how to use it

Online binary conversion drills with four modes: binary to decimal (60 seconds), decimal to binary (45 seconds), a bit-flipping challenge (reach the target within 4 flips of an 8-bit value) and a relaxed quick converter. Every bit shows its weight and can be tapped to highlight it; a correct answer scores the seconds you had left, and a wrong one reveals the answer and resets your streak.
