Efemeris
Read full descriptionHide full description
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 Hex Territory Battle Over Ancient Relics HexaRelic is a turn-based strategy game for up to 4 players. Expand your territory across a stone-tablet hex grid, lock ancient relics, and outscore your rivals. 【How to Play】 Each turn, place one tile adjacent to your territory. Surround all 6 cells around a relic to trigger a Lock — earning points, expanding the board, and unlocking bonus placements. The game ends when any player completes 5 locks. The player with the highest total score at that moment wins. 【Scoring】 Majority Lock (4+ of 6 cells yours): +3 pts Full Domination (all 6 cells): +3 pts + Erosion item Chain Bonus: consecutive locks add extra points Territory score is calculated at game end — spreading wide pays off too. 【Items】 · Erosion — overwrite one enemy tile adjacent to yours · Boundary Booster — leap to any empty cell, ignoring adjacency · Mining Drone — converts a minority lock into +1 pt automatically Knowing when to use each item is the key to victory. 【Game Modes】 · Bot Battle (Easy / Hard, up to 3 bots) · Random Match (quick online matchmaking) · Friend Battle (invite and play together) A typical match lasts 5–8 minutes — deep enough to think, short enough to replay. 【Perfect For】 · Fans of strategic tile-placement games · Players who want quick but meaningful PvP · Friends looking for a competitive mobile game together

Verdict
The clearest difference is update cadence: HexaRelic at every 2 months against Efemeris's every 8 months. HexaRelic also leads on price ($1.99 vs $3.99). Efemeris's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On ads and in-app purchases there is nothing between them.
