About this game

Two fleets face each other across a star map that does not exist yet. You build it, one tile
at a time, as you explore.
A turn-based board game duel, played solo against the AI or with a friend across phone,
tablet and PC. A game lasts about twenty minutes.
HOW YOU WIN
First to conquer five planets in ten turns takes it. Lose every planet you hold and the game
ends there.
EVERY TURN, FOUR DECISIONS
• Explore — place a tile and open a new stretch of the Celestial Vault
• Harvest — collect Star Pepper and Celestial Vanilla from the trading posts you hold
• Manoeuvre — move your galleon and frigates, spend your crew cards
• Build — buy frigates, raise fortresses, pay a planet's price
THREE NATIONS, THREE WAYS TO PLAY
The British Royal Navy, the French Royal Navy or the Spanish Armada. Each fields its own
captains and its own crew: the Spanish Governor talks a planet's price down, the French Lady
of the Night fills your holds, the Gunner opens fire.
You pick two captains and five crew members before the first tile is laid. That choice shapes
the whole game.
NOTHING IS FREE
Your holds never exceed five spices. Firing costs a Gunner card. Your captain's ability only
triggers if a Chief mate is there to relay the order — and if your galleon falls, your captain
goes down with it.
SOLO OR TWO PLAYERS
• Solo — face an AI that drafts its hand, plays its cards and races you to the fifth planet
• Duel — play a friend across Android, iOS and PC
HAND-DRAWN CELESTIAL CHARTS
Engraved constellations, gilded compass roses and inked portraits: Efemeris is played on an
old star atlas that slowly fills with light.
A complete game. No ads, no in-app purchases.
Available in English and French.
A board game duel: build the star map, claim 5 planets in 10 turns.
