About This Game

Maritime Trade King is a trading-and-sailing strategy game. As a merchant captain you move between ports, buying and selling goods at fluctuating prices to grow your fortune. Ocean currents and events add risk to each voyage, so timing your trades and routes matters.

It's a light economic game with a sense of adventure. Reading the market, planning routes, and managing risk all feed into a steadily growing trade empire.

Strategy Tips

Buy low, sell high. Prices vary by port. Stock up where goods are cheap and sell where they're dear.

Mind the currents. Ocean events can cost you — factor risk into long voyages.

Why We Built This

Maritime Trade King drops you into a trading network with six ports and ten goods. The economy is dynamic: prices shift based on supply and demand, and your own trades affect future prices. The strategy is all about route planning — a three-port circuit that buys fish, sells fish for lumber, then sells lumber for spices is more profitable than bouncing between two ports. We added weather events that block certain routes, forcing you to adapt mid-voyage.

Strategy Guide

Maritime Trade King models historical trade routes with realistic supply-demand economics. Each port has a base resource price that fluctuates based on the last 20 trades in that port — buying goods at a port where they are produced resets the supply, raising the price slightly. The optimal trade route is a triangle: buy cheap goods at a production port, sell at a consumption port, pick up local goods there, and repeat to the next city. The fastest ship upgrades (clipper class) pay for themselves within 5 round trips through reduced travel time. Storms appear on a weighted random schedule averaging one every 15 sea days. Investing in navigation upgrades before cargo capacity yields better profit-per-trip because you spend fewer days in transit and more days trading. The reputation system with each port unlocks exclusive trade goods and better prices above 60 reputation. The endgame goal is to corner a single commodity market by controlling over 50% of its trade volume.

Play Tips

The triangle trade route optimization: Port A ships spices → Port B (buy price 8 silver, sell price 22). Port B ships textiles → Port C (buy 12, sell 28). Port C ships tools → Port A (buy 10, sell 25). This triangular route generates approximately 25 silver profit per trade leg, totaling 75 silver per full circuit. The clipper ship upgrade (30% faster travel) pays for itself in approximately 5 full circuits. Storm risk can be mitigated by the Navigation upgrade: each point of Navigation reduces storm encounter chance by 5%, with 20 Navigation making storms extremely rare.

Technical Note

Technical note: the economic model tracks supply and demand per port using a damped harmonic oscillator — prices oscillate around a base value with decreasing amplitude as trade volume increases. The 5 ports have distinct base economies: Spice Port produces at 8g base, Textile Port at 12g, Tool Port at 10g, Luxury Port at 20g, and Grain Port at 5g. Travel time between ports is calculated using the Haversine formula scaled to game units.
