Random values
Randomness makes a program unpredictable on purpose. random.randint() is the dice, and seeding it the same way twice proves computer randomness is really clever arithmetic.

The big idea
This module pulls everything so far into one working system. Random numbers create surprise, variables track score and lives, conditions decide win and lose, and a loop keeps the whole thing running until somebody stops playing.
Why it matters
Games are where students first meet state — information that changes over time and must stay consistent. Managing state is the core of all serious software.
Unpacked
What you will actually learn
Three core ideas, each taught with worked examples and then practised until it feels obvious.
Score and lives
Score and lives are just variables that go up and down. The hard part is deciding exactly when they change, and making sure they never change twice by accident.
Testing
Testing means trying to break your own game — entering a letter where a number belongs, guessing outside the range, playing badly on purpose.
Did you know?
Computers cannot produce true randomness on their own. They use pseudo-random generators — formulas so complex the output only looks random.
Common mix-up
“It worked when I played it.” You knew the rules. Testing means handing it to someone who does not, and watching what they do to it.

- 1
Warm-up and big picture
Where this module fits, what you will build, and a hands-on starter that gets everyone curious about random values.
- 2
Random values
Guided teaching on random values, worked through together with the teacher.
- 3
Random values — practice lab
Independent practice, small challenges and one deliberate mistake to diagnose.
- 4
Score and lives
Guided teaching on score and lives, building directly on the previous two sessions.
- 5
Score and lives — practice lab
Applied tasks that combine random values and score and lives in one piece of work.
- 6
Testing
Testing introduced and practised, completing the toolkit needed for the project.
- 7
Project build
Guided build session for the module project: Number-guessing game.
- 8
Test, present and reflect
Finish, test against the checklist, present the work and explain the decisions behind it.
Project lab
Number-guessing game
Every module ends with something the student built themselves and can demonstrate. This is the piece that goes into their portfolio and gets explained out loud at the end of session 64.
Try this at home
Add a difficulty setting to your guessing game: easy gives ten tries and a hot-or-cold hint, hard gives four tries and silence.
It is finished when
- It works from start to finish without breaking
- You can explain every part of it in your own words
- You tested it and improved at least one thing afterwards
- Someone else used or understood it without your help
