CS Quest: Block Coding Game

CS Quest is a coding game: snap colorful code blocks together to make a character move, draw, talk, and play — then use what you've learned to build real games. No ads, no logins, no data collected.

CODE QUEST — LEARN TO CODE BY MAKING GAMES
600 hands-on lessons across 10 topics, each one a step toward something you build:
- Bring a Character to Life — steps, turns, and facing the right way
- Build a Teleporter — exact x/y positions
- Draw With Loops — repeat blocks that draw shapes
- Animate & Add Sound — say, show/hide, and sound blocks
- Wire Up Game Controls — make your world react
- Build a Scoreboard — variables that keep score
- Make Smart Decisions — if-blocks and sensing
- Build a Racing Game, a Catching Game, and an Interactive Story — put it all together

Pick your own character from 12 options — turtle, cat, fox, robot, alien and more — and it stays yours across every lesson.
