Code Master Challenges

You know the pieces; now build the machines. Code Master Challenges hands you four open-ended engineering problems and a live editor: a stopwatch driven by timers and state, generative art painted onto a canvas with loops and colour maths, a Python data analyser that turns raw exam scores into a report, and the complete logic core of a word-guessing game. Neby checks your goals automatically, but the design decisions are yours — exactly like real software work.

You will learn: doneTimers and asynchronous events doneCanvas drawing and colour maths doneAggregating data with loops doneMembership tests and game logic doneDecomposing problems into steps doneDebugging multi-part programs

1 timer Build a Stopwatch Engineer a working stopwatch with start, stop and reset buttons — powered by setInterval, state variables and live DOM updates. Coding game 15 min done 2 brush Paint with Code Turn a loop into a paintbrush: draw dozens of circles and squares on a canvas, with hsl() colours that shift on every pass. Coding game 15 min done 3 query_stats Python Data Detective Investigate a list of exam scores with Python: count, average, highest, lowest and pass rate — printed as a clean report. Coding game 15 min done 4 sports_esports Python Word Game Build the brain of a hangman game: test guesses with "in", track wrong letters in a list, and reveal the masked word. Coding game 18 min done
