About
BIT turns computer science fundamentals into an endless puzzle game — not flashcards, not video lectures, just real questions with real answers, one after another.
WHAT'S INSIDE
Play — An endless stream of puzzles drawn from everything you've learned, weighted toward what you're starting to forget. Build a streak, chain a combo, and watch a running total climb.
Explore — Every concept BIT teaches, organized like a real curriculum: prerequisites, learning objectives, worked examples, and real-world uses. From what a bit actually is, through binary arithmetic, arrays, linked lists, sorting, searching, and networking basics.
Build — Hands-on projects where you actually build something: wire up a binary counter, construct an array from scratch, and see the concept work, not just read about it.
Lab — Interactive playgrounds for experimenting freely with the ideas Play and Explore introduce.
Puzzle of the Day — One challenge, the same for everyone, every day. Solve it, share your result, keep your streak alive without committing to a full session.
WHAT BIT DOESN'T DO
No ads. No accounts. No leaderboards. No in-app purchases. No data collection of any kind — everything you do stays on your device. BIT works completely offline because it has to: there's no server to talk to in the first place.
WHO IT'S FOR
Students learning computer science for the first time, self-taught programmers filling in fundamentals they skipped, and anyone who likes the idea of a daily brain-training habit that leaves them knowing something real.
New content is added regularly — more domains, more concepts, more puzzle types — as an ongoing project, not a finished product.
