Mini Lesson
Every great game starts as an idea on paper. Before you write a single line of code, you decide what the game IS — who the player controls, what they are trying to do, and how the game ends. A good design plan turns a vague idea into a buildable mini-game with clear rules.
The Five Game Design Questions
Answer these five questions and you have the skeleton of a working mini-game. Skip any one of them and the game will feel half-finished.
- Game name — what is it called?
- Goal of the player — what are they trying to do?
- Main character — who or what does the player control?
- How the player wins — what triggers the WIN screen?
- How the player loses — what triggers the LOSE screen?
Game Elements Map to Code Concepts
Every part of your game becomes a piece of code. Knowing which code concept matches which game element makes building the game much faster.
- Score — a variable that goes up when the player does the right thing.
- Hero moves — the code an event handler runs after a key press or tap.
- Enemy spawns over and over — a loop that repeats while the game runs.
- Game over screen — a condition checked again and again while the game runs ("if health is 0, then stop").
- Player presses a key — an event the game listens for, so its handler can run code.
Win and Lose Conditions
A condition is just a yes/no question the game asks: "Is the score 10 or higher?" "Is health zero?" When the answer flips to YES, the game responds. Without these checks, your game has no end and no goal.
- Win condition — the rule that ends the game in success (e.g. score reaches the goal, all enemies defeated, level finished).
- Lose condition — the rule that ends the game in failure (e.g. health hits 0, time runs out, player falls).
- Both conditions are checked every time the game loop repeats.
Words to know
sprite
A picture or shape that represents a character or object in a game.
score
A number variable that goes up or down based on what the player does.
level
A stage of the game with its own challenges; clearing it unlocks the next.
win condition
The rule that decides when the player has won (e.g. score = 100).
lose condition
The rule that decides when the player has lost (e.g. health = 0).
Tip: design first, code second. A page of planning saves a lot of debugging — you cannot build what you have not decided.
