Description #
Lightbot is a puzzle-based programming game that teaches key coding concepts such as sequencing, loops, and conditionals. Players control a robot that lights up tiles using simple commands in a visual interface, making it ideal for introducing algorithmic thinking.
History #
Lightbot was created by Danny Yaroslavski in 2008 as a Flash-based educational game. It gained popularity due to its accessibility and effectiveness in teaching core programming logic without requiring actual code. It’s used globally in classrooms and has been featured in the Hour of Code initiative.
Hello World Code #
Lightbot does not use text-based code. Instead, users drag and sequence blocks like:
- Move Forward
- Jump
- Light Tile
- Procedure 1
- Loop
A typical beginner sequence might look like:
[Move Forward] → [Light] → [Move Forward] → [Light]How to Run #
