Overview

Cosmic Coasters is a strategy game where players teleport ships between moons, battling opponents using Rock-Paper-Scissors combat. Each moon has special terrain including Teleport Pads, Control Points, and Factories. The goal is to transport one of your ships back home from any opponent’s Teleport Pad by controlling their teleportation system.

Components

• 4 moon boards (Io, Europa, Ganymede, Callisto), each with spaces for ships
• Each player needs 7 matching game tokens (coins, dice, meeples, or similar)
• Rules sheet

Setup

1. Each player places their 7 ships onto their home moon, leaving 2 Factories empty.
2. Play Rock-Paper-Scissors to determine who goes first.
3. If fewer than 4 players, extra moons cannot be visited.

Turn Structure

On each turn, a player performs exactly one of three actions:

1. Teleport a ship
2. Build a ship
3. Move a ship one space

Actions

Teleport:

• If you are the only player occupying 2 or more Control Points around a Teleport Pad, you may transport the ship on that pad to any spot on another moon (or into nothingness).
• An arriving ship destroys whatever ship it teleports onto.

Build:

• If you occupy the 2 Control Points flanking an empty Factory on any moon, and you have spare parts (destroyed ships), you may build a new ship on that Factory.

Move/Combat:

• Move a ship into any connected adjacent space.
• If another ship occupies that space, you are attacking it.
• Combat is resolved by Rock-Paper-Scissors:
  • Win: Defender destroyed; attacker enters the space.
  • Lose: Attack fails; no one moves.
  • Draw: Defender destroyed, but attacker does not move in.

Special Powers (one per player/moon):

Power	Effect
Teleport Inhibitor (Stinging Defense)	Opponents must win a round of RPS before teleporting to your moon; ties allow landing only on empty spaces
Warning System	When attacked and you win, opponent’s ship is destroyed
Rapid Transit	May move 1 or 2 spaces; cannot jump over ships; if 2-space attack fails, choose which space to remain in
(4th power varies)	When someone teleports onto your ship, you may escape into any adjacent empty space; if trapped, destroyed

Scoring / Victory Conditions

Win: Be the first to transport one of your ships back to your home moon from any opponent’s Teleport Pad.

Elimination: When a player has only 1 ship left on their home moon, they lose and are eliminated. Their remaining home ship and all their ships on other moons are destroyed. Their moon remains in play.

Special Rules & Edge Cases

• If more than 2 players, eliminated players’ moons remain in play for others.
• Fewer than 4 players means extra moons are inaccessible.
• Dice variant: Instead of RPS, attacker rolls one die – specific results map to Win/Lose/Draw.
• Advanced variant (Lunar Invaders) exists using Looney Pyramids.
