Overview

Blue Moon City is a set-collection and area-majority game where players rebuild a ruined city to earn crystals, then offer those crystals to a central obelisk. Players move around building tiles, play cards to contribute to reconstruction, and score rewards when buildings are completed. Dragons provide bonus golden scales that convert into additional crystals. The first player to make enough offerings to the obelisk wins.

Components

• 21 Building tiles (double-sided: sketch/completed)
• 1 Obelisk
• 80 Cards (10 for each of 8 peoples/colors)
• 4 Player figures
• 40 Player markers (10 cubes per player, 4 colors)
• 40 Crystal tokens (12 of value 1, 28 of value 3)
• 15 Golden dragon scales
• 3 Dragon figures

Setup

1. Place the courtyard tile in the center. Place three temples and the palace adjacent to it as shown in the rules. Shuffle remaining building tiles and place randomly to complete the city shape (all sketch-side up).
2. Place the obelisk next to the city.
3. Place crystal tokens face up on one side of the obelisk.
4. Place golden scales on the other side: 4 players = 15 scales, 3 players = 12 scales, 2 players = 9 scales.
5. Place three dragons next to the city.
6. Each player chooses a color, places their figure on the courtyard and takes their 10 markers.
7. Shuffle cards, deal 8 to each player, place rest as facedown deck.

Turn Structure

Play clockwise. On your turn, perform these phases in order:

1. Movement

Move your figure up to 2 steps along adjacent (orthogonal) building tiles. You may change direction. Movement is optional.

2. Contribution / Offering

At your current building tile, make contributions to reconstruct the building. Or, if at the courtyard, make an offering to the obelisk.

3. Discard and Draw Cards

Discard 0, 1, or 2 cards to the discard pile, then draw 2 more cards than you discarded from the deck. (Reshuffle discard pile when deck runs out.)

Card Powers: During your turn, you may discard cards to use their special powers (detailed on each card).

Actions

Making Contributions

Each building tile shows 1-3 boxes with a colored number indicating required contribution value.

• Discard cards of the matching color with total value equal to or greater than the box number.
• Place one of your markers (cubes) on that box.
• You may make multiple contributions per turn, each with separate cards.
• Royal Palace boxes accept any single color.

Completing Buildings

When the last open box on a building is filled:

• Most markers reward: Player with the most markers on the building (ties broken by leftmost marker) receives the primary reward (crystals, cards, or golden scales).
• Participation reward: Each player with at least one marker receives the secondary reward.
• Neighborhood bonus: Each player with at least one marker also receives rewards from all orthogonally adjacent COMPLETED buildings’ neighborhood reward icons.
• Markers are retrieved, tile is flipped to completed side.

Dragons

• Dragons are moved via card powers.
• When dragons are on your building tile and you make a contribution, receive 1 golden scale per dragon present (once per turn regardless of number of contributions).
• Dragons on the courtyard have no effect.

Golden Scales Scoring

When the last golden scale is taken:

• Single player with the most scales: 6 crystals
• Tied for most: 3 crystals each
• Any player with at least 3 scales: guaranteed 3 crystals
• Players with fewer than 3 scales: nothing (but keep their scales)
• Players who received crystals return their scales. Others keep theirs.

Offerings to the Obelisk

When your figure is at the courtyard:

• Spend the indicated number of crystals to place a marker on the next available obelisk box (filled bottom to top).
• In a 2-player game, do not use the two shaded “7” boxes at the base.
• Pillar card powers can enable multiple offerings per turn.

Scoring / Victory Conditions

Win Condition: First player to make the required number of offerings to the obelisk wins:

Players	Offerings to Win
2	6
3	5
4	4

Alternate endings:

• If all buildings are rebuilt without anyone reaching the required offerings: play until everyone has made as many offerings as they can. Most offerings wins (tiebreaker: most remaining crystals; further tie = shared victory).
• If all players run out of markers (all 10 placed): game ends in a draw.

Special Rules & Edge Cases

• Crystal token values are kept facedown (secret from opponents).
• Cards drawn from completed building rewards are kept facedown until your turn ends, then added to hand.
• Each player is limited to 10 markers total (for buildings and obelisk combined).
• Crystal supply is unlimited; use substitutes if needed.
• Golden scale supply is limited by player count.
• Unclaimed golden scales due to supply depletion still count toward the player’s total when scoring.
• You may visit the same building tile multiple turns to make separate contributions.
• When reshuffling the discard pile, do not include cards currently in play.

Variant Setup

For more variety, place all building tiles (except the courtyard) randomly, ignoring the prescribed positions for temples and palace.
