Computer Science Quest

Computer Science Quest turns learning computer science into a game — two complete, Duolingo-style tracks, no ads, no logins, no data collected. PROCESS QUEST — Learn CS Subjects Walk a level-by-level path through 12 full computer science subjects, 60 bite-sized lessons each: - Operating Systems - Data Structures - Digital Logic - Computer Networks - Databases (DBMS) - Artificial Intelligence - Machine Learning - Web Technologies - Software Engineering - Cloud & Distributed Systems - Compilers - Cybersecurity Every lesson pairs a short explanation with a hands-on puzzle — multiple choice, drag-to-order, sort into buckets, match pairs, or wire up a logic circuit. Lock-and-unlock progression keeps you moving forward one concept at a time, all narrated by Process the turtle. CODE QUEST — Learn to Code Snap colorful blocks together, Scratch-style, to move a character, draw shapes with loops, animate a story, and build simple games. 10 topics, 60 lessons each — 600 lessons in total — covering movement, loops, events, variables, sensing, and full combo projects like a racer, a chaser, and an interactive story. Pick your own on-screen character from 12 options — turtle, cat, fox, robot, alien and more — and it's yours across every lesson. BUILT FOR FOCUSED LEARNING - 1,300+ lessons across both tracks - Long-press-and-drag block editing, built for touch - Light, Dark, or System appearance — your choice - Progress saved locally, right on your device - No ads. No accounts. No tracking. Whether you want to understand how operating systems, networks, and databases actually work, or you want to learn to code by building your first little games, Computer Science Quest turns the fundamentals into something worth coming back to.
