Game Design Principles

Design thinking for engaging games.

1. Core Loop Design

The 30-Second Test

Every game needs a fun 30-second loop:
1. ACTION → Player does something
2. FEEDBACK → Game responds
3. REWARD → Player feels good
4. REPEAT

Loop Examples

Genre	Core Loop
Platformer	Run → Jump → Land → Collect
Shooter	Aim → Shoot → Kill → Loot
Puzzle	Observe → Think → Solve → Advance
RPG	Explore → Fight → Level → Gear

2. Game Design Document (GDD)

Essential Sections

Section	Content
Pitch	One-sentence description
Core Loop	30-second gameplay
Mechanics	How systems work
Progression	How player advances
Art Style	Visual direction
Audio	Sound direction

Principles

Keep it living (update regularly)
Visuals help communicate
Less is more (start small)

3. Player Psychology

Motivation Types

Type	Driven By
Achiever	Goals, completion
Explorer	Discovery, secrets
Socializer	Interaction, community
Killer	Competition, dominance

Reward Schedules

Schedule	Effect	Use
Fixed	Predictable	Milestone rewards
Variable	Addictive	Loot drops
Ratio	Effort-based	Grind games

4. Difficulty Balancing

Flow State

Too Hard → Frustration → Quit
Too Easy → Boredom → Quit
Just Right → Flow → Engagement

Balancing Strategies

Strategy	How
Dynamic	Adjust to player skill
Selection	Let player choose
Accessibility	Options for all

5. Progression Design

Progression Types

Type	Example
Skill	Player gets better
Power	Character gets stronger
Content	New areas unlock
Story	Narrative advances

Pacing Principles

Early wins (hook quickly)
Gradually increase challenge
Rest beats between intensity
Meaningful choices

6. Anti-Patterns

❌ Don't	✅ Do
Design in isolation	Playtest constantly
Polish before fun	Prototype first
Force one way to play	Allow player expression
Punish excessively	Reward progress

Remember: Fun is discovered through iteration, not designed on paper.
