About Leonardo's Island

Leonardo’s Island lets you design and build ships, then test them in regattas and naval battles. You have different play modes: Sail solo in Around the Island, or compete online in Battles and Regattas with other players. If you prefer to play only with friends, Steam Friends lets you challenge them in races and naval combat.

Build your shipsCustomize your ship’s shape, combine sails and weapons to match your style. Each hull changes how you sail. Each new sail delivers new speed and freedom. Regattas or Battles! Every voyage brings gold and experience — or an inglorious end at the bottom of the ocean. Grow your shipsUnlock powerful cannons, reduce their weight, boost their damage.

Become the terror of the local seas. Cannonballs, bombs, chain shot, grapeshot — and your deadly aim. Break their masts, burn their decks, and plunder their gold from the wreckage.
