🏝️ Game Board Analysis

Settlement Analysis

Hover over a colored dot to analyze settlement potential.

Green = High Yield, Red = Low Yield

🎲 Dice Distribution

Probability distribution of 2d6 rolls. Maximizing exposure to high-probability numbers (6, 8) is fundamental to resource generation stability.

🤖 Strategy Tournament

Run a Monte Carlo simulation to evaluate strategy performance over thousands of games. This helps identify which logic dominates in the current meta.

📚 Strategy Codex

Greedy

Pure production maximizer. Always picks the highest pip-count vertex, ignoring resource diversity entirely.

Setup

Picks the highest total pip-count vertex every time.

Mid-Game

Cities > Settlements > Dev Cards (30%) > Roads.

  • Strength: Strong early production, snowball potential
  • Weakness: May double up on resources, leaving blind spots

Balanced

Fills resource gaps methodically. Second settlement targets resource types the first one missed.

Setup

First settlement: best diversity score. Second: fills resource gaps from first.

Mid-Game

Same build loop as Greedy (cities > settlements > dev cards > roads). Trades only with the bank.

  • Strength: Rarely bottlenecked, covers all 5 resources
  • Weakness: No player trading, no adaptive play

Probability

Targets the statistical sweet spot. Squares dice probability for extra weight on 6s, 8s, 5s, and 9s.

Setup

Targets vertices adjacent to 6s, 8s, 5s, 9s — squares the probability for extra weight.

Mid-Game

Same build loop as Greedy.

  • Strength: Consistent income every turn
  • Weakness: May stack on one resource type if high-prob hexes are clustered

Port-Focused

Builds a mid-game trade engine by weighting port locations during setup, then leverages bank/port trades.

Setup

Adds a yield bonus (+0.5) for vertices on port locations.

Mid-Game

Trades aggressively with bank/ports when holding excess, then builds like Greedy.

  • Strength: Mid-game trade engine unlocks flexible building
  • Weakness: Weaker start if port spots have low yield

Ore-Wheat

Specialized "City & Dev Card" rush. Scores Ore and Wheat at 2x weight, everything else at 0.5x.

Setup

Scores Ore and Wheat at 2x, other resources at 0.5x.

Mid-Game

Buys every dev card it can afford first, then upgrades cities, then falls back to Greedy loop.

  • Strength: Fast Largest Army, strong city upgrades
  • Weakness: Ignores expansion, fragile if Ore/Wheat hexes get robbed

Random

Purely stochastic baseline. Makes random legal moves — useful for benchmarking real strategies.

Setup

Picks any legal vertex at random.

Mid-Game

Randomly attempts builds (settlement, road, city, dev card) up to 10 times per turn.

  • Strength: Unpredictable, useful as a baseline
  • Weakness: No strategy — purely stochastic
