Scratch Maze Game Tutorial

In this week’s lesson we will be working our way through the Scratch maze game tutorial. You will learn how to :

  • Move and animate Scratch, using coordinates, costumes and a game loop
  • Keep track of and switch between levels using variables
  • Keep track of the score and player lives using variables
  • Add power-ups and moving baddies to your game

As always it is best if you watch, and importantly listen to, the tutorial video. The tutorial video goes further than just showing you what blocks to use, it explains how it works and why I chose to do it that particular way. There are many ways to program games and an important skill is learning when to use each approach!

Have a go at this demo of the game to get a feel for how it works!
