Introduction & Learning Objectives
Learning Objectives
Define what a 'game goal' is in their own words.
Identify the main goal in simple games they play.
Explain the difference between a 'win condition' and a 'lose condition'.
Create a clear, single-sentence goal for a new game idea.
Use 'if-then' statements to describe a game's win condition.
Connect a game goal to a piece of data, like a score.
What's the first thing you try to do when you play a new video game or board game? 🎮 Let's figure out why knowing the goal is the most important part!
Today, we are going to be game designers! We will learn what a game goal is and why every game needs one. Knowing the goal helps us build fun games and tells the player how to win.

TermDefinitionExample
Game GoalThe main purpose of the game. It's what the player is trying to achieve.In a soccer game, the goal is to score more points than the other team.
ObjectiveA small task or step you need to complete to reach the main game goal.To win the soccer game, one objective is to kick the ball into the other team's net.
Win ConditionThe exact rule that tells the game 'The player has won!' It's how the game knows the goal has been met.The win condition is when the timer runs out and your team has the higher score.
Lose ConditionThe rule that tells the game 'The player has lost.' This makes the game challenging.A lose condition is if the other team has a higher score when the timer runs out.
ScoreA piece of data (a number) that keeps track...

Core Syntax & Patterns
The Collection Goal
IF player's score == [target number], THEN player wins.
Use this when the goal is to collect a certain number of items, like coins, stars, or jewels. An event 'WHEN player touches item' makes the score go up.
The Destination Goal
IF player touches [finish line object], THEN player wins.
Use this for games where the player needs to reach a specific place, like a finish line, a castle door, or a treasure chest.
The Survival Goal
IF timer == 0 AND player's health > 0, THEN player wins.
Use this when the goal is to last for a certain amount of time without getting caught or running out of health.

A.The player wins the game faster
B.The king will take the jewel, because the order doesn't matter
C.The game will break and turn off
D.The goal cannot be completed because the sequence of events is wrong
Challenging
A game is programmed so a "You Win!" event happens when `score` is 10. A player has a score of 12, but the game isn't ending. What is the most likely problem in the game's conditional logic?
A.The code probably says "IF `score` is EXACTLY 10, THEN win" instead of "IF `score` is 10 OR MORE, THEN win."
B.The player's score is too high, so they lose.
C.The "You Win!" screen must be broken.
D.The game needs the score to be an odd number like 11.
