Free offline logic lessons — six single-file games + seven lessons, Uganda first # Offline Game School **Free, offline, runnable lessons in logic and computer thinking — built as fun and retro games in plain JavaScript. No internet. No install. No cost.** Open any game file in a browser (double-click the `.html`), and it just runs. Every game is ONE self-contained file — no libraries, no downloads, no accounts. This works on old laptops, cheap phones, and school computers that have no network. Built for kids and for people learning with little or nothing — starting with the students and families supported by RUN ANGELLA MATHEW CENTER UGANDA LTD (kadondibetty) — a center in Uganda that pays tuition and school supplies for orphans and vulnerable children. ## Why games? You learn to think like a computer by building and playing with logic. Every game here teaches a real computer-science idea, and every game can be opened and changed by the learner. The code is the lesson. | Game | File | What you learn | |---|---|---| | Guess the Number | `games/guess-the-number.html` | loops, if/else, binary search | | Rock Paper Scissors | `games/rock-paper-scissors.html` | conditions, random, counters | | Tic Tac Toe | `games/tic-tac-toe.html` | 2D arrays, win checking | | Snake | `games/snake.html` | arrays, timers, collision, state | | Mastermind | `games/mastermind.html` | logic deduction, feedback loops | | Memory Match | `games/memory-match.html` | arrays, events, shuffle | ## How to use (offline, no internet) 1. Copy the `games/` folder to any computer or phone (a USB stick works). 2. Double-click a game file. It opens in the browser. 3. Play. Then open the file in a text editor (Notepad, or any editor) and change one number — see what breaks and what changes. 4. Read the matching `lessons/` playbook for the idea behind the game and the "make it yours" challenge. Everything works on a school computer that has never seen the internet. ## The project-based path (like OSSU, but in one repo) OSSU is a famous free self-taught computer-science curricu …
