Block of Rum

Block of Rum is a sandbox about building sailing ships and piracy. You sail through a procedurally generated world, fight other ships and capture towns to gather resources and improve your ship.

Build your ship

You assemble ships from blocks with different characteristics, balancing speed, strength and firepower while designing their appearance. Your creation needs to stay afloat and move at least a little. Ships also carry cargo: blocks in your inventory remain where you bought them and disappear if left unattended, while blocks loaded onto your ship travel with you unless the ship is destroyed. You can sell extra cargo in cities.

Cities and trade

Dozens of cities are scattered across islands and continents. They trade with one another and feud, and some capture others to form empires. Cities do not tolerate pirates, so your ship may be attacked while you are occupied. You can buy missing blocks, replenish your crew and find dubious jobs in cities.

Sea battles

You attack ships and cities to take what remains after a battle. Fire cannonballs or grapeshot by turning your ship's cannons toward the enemy; there is no aiming sight. Your ship's strengths can help you win, but damage changes its characteristics, and a single hit can alter the course of a battle.

Boarding actions

You can board an enemy ship to finish a fight or capture it in better condition. During boarding, you command your crew in turn-based combat, alternating between hand-to-hand skirmishes and musket volleys. The action pauses between exchanges so you can assess the situation and issue orders. Both crews act simultaneously, and their numbers may differ.
