Rules by Category

Settlement placement

  • Must be placed at the end of one of your connected roads.
  • Must obey the distance rule against all players' settlements and cities.
  • Initial setup phase ignores the road-connection requirement only for first placements.

City upgrade

  • Can only upgrade your own existing settlement.
  • Cities do not bypass distance-rule legality for new settlements.
  • Return the upgraded settlement piece to your supply.

Road placement

  • Road must connect to your existing road, settlement, or city.
  • Opponent settlements or cities break continuation for road extension and longest-road counting.
  • Cannot continue a road through another player's building vertex.

Common Rule Disputes

Referee-style answers for the situations that cause the most table arguments.

Q: I bought a development card this turn. Can I play it now?

Ruling: No. Development cards bought this turn cannot be played until your next turn.

Rulebook: Exception: Victory Point cards can be revealed immediately.

Q: An opponent built on my road. How is Longest Road counted now?

Ruling: Your chain is split. Count the longest continuous segment from each side.

Rulebook: Road pieces stay on the board; only scoring continuity changes.

Q: I rolled a 7. Do we discard first or move robber first?

Ruling: Discard first (all players with 8+ cards), then move the robber.

Rulebook: Discard happens before steal resolution.

Q: Can I play Monopoly on someone else's turn?

Ruling: No. Except Victory Point cards, development cards are played only on your turn.

Rulebook: Timing disputes usually come from this rule.

Q: Can I play two Knight cards in one turn?

Ruling: No. Only one development card can be played per turn.

Rulebook: You may still buy multiple cards in the same turn.

Q: Can I trade resources for future promises?

Ruling: No. Trades must be immediate resource-for-resource exchanges.

Rulebook: No deferred deals, favors, or future-turn commitments.

Q: Can I gift resources to another player?

Ruling: No. Exchanges must be mutual trades.

Rulebook: Free resource transfer is not legal in official rules.

Q: Can I move robber back to the desert?

Ruling: Yes. The desert is a valid robber destination.

Rulebook: Robber can be moved to any legal hex including desert.

Q: Do cities count as roads for Longest Road?

Ruling: No. Settlements and cities never add road length.

Rulebook: They can block continuity if owned by an opponent.

Q: I hit 10 points outside my own turn. Do I win instantly?

Ruling: No. Victory is declared only on your own turn.

Rulebook: Points can exist before declaration, but win timing is fixed.
