Design abstract strategy games—games with perfect information, no randomness, and strategic depth. Provides frameworks for ideation, design, and evaluation.
Core Definition
Abstract strategy games require:
Perfect Information: All game state visible to all players
No Randomness: Outcomes determined solely by player decisions
Minimal Theme: Mechanics over narrative
Player Agency: Success depends on strategic thinking

Design Principles
The Holy Grail: Depth-to-Complexity Ratio
Maximum strategic depth with minimum rules complexity.
How to achieve:
Start with single strong core mechanism
Remove anything that doesn't support the core
Every rule should create multiple strategic implications
Prefer emergent complexity over explicit rules
Meaningful Decision Architecture
Four components of meaningful choice:
Awareness: Players understand options
Consequence: Immediate and long-term effects
Permanence: Decisions have lasting impact
Reminders: Game state reflects past choices
Ideal Parameters:
Branching factor: 20-40 moves/turn for human play
Horizon: 3-5 moves ahead with effort
Multiple paths: 3-4 viable strategies minimum
Core Mechanisms Toolkit
Board Topology
Grids: Square, hexagonal, triangular, irregular
Connectivity: How spaces relate
Edges: How boundaries affect strategy
Size: Larger = exponentially more complex
Piece Systems
Uniform: All pieces identical (Go)
Differentiated: Unique abilities (Chess)
Transforming: Change during play (Checkers kings)
Ownership: Fixed vs. capturable
Movement & Placement
Placement only: Pieces don't move once placed (Go)
Counter-strategies exist for every strong position
Passive play punishable
Aggressive play doesn't guarantee victory
Design Process
Three Starting Points
1. Mechanism-First
Identify interesting core mechanic
Build minimal game around it
Add only what enhances core
Remove everything else
2. Experience-First
Define target player experience
Identify mechanisms that create it
Prototype and test rapidly
Iterate on feedback
3. Constraint-Based
Set specific limitations (components, time, space)
Find creative solutions within constraints
Often leads to elegant designs
When to Add/Remove Complexity
Add when:
Core feels solved too quickly
Players master in <10 plays
Decisions feel obvious
Remove when:
Rules take >10 minutes
Players forget rules
Strategies feel arbitrary
Scrap when:
No tweaking fixes fundamentals
Core mechanism isn't interesting
Feels like inferior version of existing game
Brainstorming Techniques
1. Mechanism Extraction from Non-Games
Extract from physics, biology, economics, chemistry, social systems:
Pieces that "decay" unless refreshed (entropy)
Moves creating "waves" along patterns (physics)
Pieces forming "bonds" limiting movement (chemistry)
"Market" squares with fluctuating values (economics)
2. Extreme Property Isolation
Take one property to absolute extreme:
Game where pieces visible only when adjacent to your others
Every move must maintain rotational symmetry
Pieces exist only one turn unless refreshed
Board wraps in non-intuitive ways (Klein bottle)
3. Impossible Constraint Challenges
Start with seemingly impossible constraints:
Game on a 1D line
Pieces in probability clouds until observed
Victory condition voted on by piece positions
Pieces leave "trails" becoming new pieces
4. Anti-Pattern Starting Points
Design intentionally bad games, then invert:
Always-draw game → Add accumulating positional advantages
Pure calculation → Add pieces that change rules
Dominant strategy → Make it vulnerable to specific counters
5. Mathematical Structure Mining
Pieces move along Hamiltonian paths only
Positions valued by prime factorization
Fractal boards with repeating patterns
Moves must preserve mathematical invariants
Evaluation Framework
Strategic Richness Indicators
Depth:
Games last 20+ meaningful turns
Opening, midgame, endgame feel distinct
Multiple viable opening strategies
Comebacks possible but not trivial
Complexity:
New players grasp rules in <5 minutes
Experts keep discovering patterns
High-level play looks different from beginner
Common Failures
Problem

Solution
Analysis Paralysis
Excessive turn time
Limit options, clearer objectives
Solved Game
Same outcome always
Increase branching, add variety
Kingmaker
Loser picks winner
Simultaneous resolution
Testing Protocol
Phase 1: Proof of Concept
Test core mechanic in isolation
Verify basic fun factor
Identify broken strategies
Phase 2: Mechanics
Test each subsystem
Look for unintended interactions
Measure game length
Phase 3: Integration
Full game, all systems
Different skill levels
Quantitative data
Phase 4: Blind Testing
Players learn from rulebook only
Identify ambiguities
Test learning curve
Testing Checklist
Mechanical
All rule interactions verified
Edge cases resolved
Victory achievable but not trivial
No unbreakable stalemates
Balance
First player wins 45-55%
Multiple strategies win regularly
No dominant opening
Skill affects outcome
Experience
Games complete in target time
Players want rematch
Decisions feel meaningful
Players improve with practice
Accessibility
Rules learned in <5 minutes
Rules fit one page
No ambiguous situations
Components distinguishable
Quick Evaluation Filters
30-Second Test: Can you explain core concept in 30 seconds?
Originality Test: Does it feel like variant of existing game?
Decision Test: Are there obviously interesting decisions?
Depth Test: Could this sustain interest for 50+ plays?
Session Structure (2 Hours)
10 min: Pick 3-4 brainstorming techniques
60 min: Generate 15-20 ideas per technique
20 min: Expand 5-10 promising ideas
20 min: Combine and explore hybrids
10 min: Apply filters, select for prototyping
Anti-Patterns
1. Complexity as Depth
Pattern: Adding rules, exceptions, and special cases to make the game feel "deeper."
Why it fails: Complexity and depth are different. Complex rules create burden; depth emerges from simple rules with rich interactions. Chess has simpler rules than many shallow games.
Fix: Ruthlessly remove complexity that doesn't add strategic options. If a rule requires explanation but doesn't create interesting decisions, cut it.
2. Solved Game Blindness
Pattern: Creating a game where optimal play always produces the same outcome—often draws or first-player wins.
Why it fails: Once players discover the solution, the game becomes rote execution rather than strategic exploration. No amount of polish fixes a solved game.
Fix: Test extensively with strong players. If games start converging on identical patterns, add asymmetry or increase branching factor. The pie rule helps but doesn't solve fundamental issues.
3. Decision Paralysis
Pattern: Every position has dozens of equally viable options with unclear consequences.
Why it fails: Strategic games need meaningful comparison between choices. When all options seem equivalent, decisions become random rather than strategic.
Fix: Reduce branching factor or create clearer evaluation heuristics. Players should be able to identify 3-5 promising moves without analyzing every possibility.
4. Theme Creep
Pattern: Adding narrative or thematic elements that don't connect to mechanical decisions.
Why it fails: Abstract strategy games work because mechanics are the content. Theme that doesn't inform decisions is decoration that slows play without adding depth.
Fix: Either commit to a themed game (different framework) or keep theme purely cosmetic. Don't let theme suggest mechanics that don't serve strategy.
5. Perfect Information Violations
Pattern: Adding hidden information, simultaneous resolution, or dice "for variety."
Why it fails: Abstract strategy games are defined by perfect information and determinism. Adding randomness or hidden elements creates a different game type with different design principles.
Fix: If the game needs variety, add it through board setup, victory condition selection, or piece starting positions—not through mid-game randomness.
