BIT turns computer science fundamentals into an endless puzzle
game — binary, algorithms, data structures, and more. No ads, no
accounts, nothing ever leaves your phone.
What's inside
Play — an endless stream of puzzles, weighted
toward what you're starting to forget
Explore — every concept BIT teaches, with
prerequisites, worked examples, and real-world uses
Build — hands-on projects where you actually
build something, not just read about it
Lab — interactive playgrounds for experimenting
freely
Puzzle of the Day — one challenge, the same for
everyone, every day
