Start With Binary Demo
Watch a byte change live while you flip each bit on and off. This is the fastest way to internalize place values.
Interactive Learning
Practice Lab
Use the switchboards below to train binary place values, read bytes faster, and build intuition for hexadecimal without hunting through hidden CySA routes.
Binary Demo
Toggle bits and watch the decimal value, grouped binary byte, and hex byte update live.
Binary Backup
Build an 8-bit number by hand and read it back as binary, decimal, and hexadecimal.
Hex Switch Game
Set a target hex value and train your eye to match it by flipping the right bits.
Use Binary Backup
Read the same byte as binary, decimal, and hex at once so the relationships between the formats become automatic.
Finish With Hex Game
Set a hex target, then match it by flipping the correct switches without relying on a conversion table.
