Digital Foundations

Meet the machine you’ll command to build games — and the one rule it never breaks.

Before you write code, you plan. An algorithm is just a clear plan — and every great game starts with one.

Code runs top to bottom, and “variables” let your program remember things. Time to write real code — every line explained.

Two ideas power almost every game: repeating things (loops) and making choices (conditions). Let’s master both.

Everything so far — variables, sequence, loops, conditions, input — comes together into a real, playable game. Move, catch, score!
