Coders give computers step-by-step directions. If one step is wrong, the program has a bug. Finding and fixing it is called debugging.
Blockly Games: Maze
Blockly Games Maze: stack code blocks to move the character to the end of the maze. The later levels use repeat loops and if blocks.
- Read the goal for each level.
- Put your blocks in order and press Run.
- If it doesn’t work, find the bug, fix it, and try again.
