How It Plays

No dice. No board. Ships roll, cannons fire, islands pay out.

One action per ship

Move it, fire from it, or collect from the island it's touching.

Real cannons

Load a ball, press the arm, and watch it go. Where it lands is up to you.

Take islands

Plant a flag to claim one. Held islands pay coins and mount cannons.

Spend coins

Full sail for speed. Repair crews to patch a hull. Boarding parties to steal a ship.

Everything else is in the rulebook.

What the first full-fleet game changed in rulebook v0.4.

Rulebook v0.4 · Released 2026-05-18
  • Faster fleets

    Every faction except the Islanders gains a click of movement. Shadow Fleet now matches Queen's Fleet.

  • Corsairs down to three sloops

    Four was too much to track each turn. Three sloops at Move Count 4 still flank fine.

  • Islanders down to one fitting

    One hit leaves a catamaran dead in the water. Fast and fragile, as intended.

  • Deploy at the table edge

    Ships start touching the edge. The old 3-inch buffer wasted space.

  • Ricochets

    The first ship a cannonball touches takes the hit. Bounces after that do nothing.

  • Cannons need a crew

    To fire any cannon, a ship of yours must be touching it and spend its action. Islands no longer fire on their own.

  • Always Underway

    Optional mode. Ships must move forward every turn and may steer or fire, not both.
