For the beginners, there's a 20-step guide to creating a game called Crustacean Storm, using the simple drag-and-drop approach of Scratch. They're also offering a £250 prize to whoever creates the best game of their own using Scratch. Then there's a more advanced guide to creating a shoot-em-up called Raspberry Pie using Python. Don't worry if you don't have a Raspberry Pi yet: both tutorials can be followed on a PC.
