Steer your ship by dragging anywhere on the page with a mouse or a finger, or click the game once and use the arrow keys. The cannons fire on their own. Press the big button, or Space, to fire a broadside. A voyage ends when you sink the sea monster at the end of it, or when your hearts run out. It is the whole game that is coming to the App Store and Google Play — built from the same code, and not in either store yet.
What this page does and does not do
- Your progress stays in this browser. Voyages won, stars, doubloons and upgrades are kept in this browser’s storage, not in an account — so they do not follow you to another browser, another computer or your phone, and clearing your site data or playing in a private window loses them. There is no app yet to carry them over to.
- There are no ads here. Not as a favor: the ad network has no browser version, so there is nothing to show. The store versions will carry a banner on the menus and optional videos that pay bonus coins; this one offers neither.
- Nothing is sold, and the game sends nothing. No in-app purchases, no account and no sign-in. The doubloons are spent on your ship and convert to nothing.

One screen fetches a font from Google. The game engine is
served from this domain rather than from Google’s CDN, which
is not the framework default and was changed deliberately. The
game’s own typeface, Roboto, is bundled with it and served from here too.
The exception is the Shipwright, which draws an arrow Roboto does not have:
opening it makes the engine fetch Noto Sans Symbols from
fonts.gstatic.com. We opened the title screen, a voyage, the sea chart, the Shipwright, the logbook and settings against this build on 25 September 2026, and no other screen asked for anything.
If it runs badly
It is about three megabytes to reach the title screen, of which the rendering engine is more than half and the title music a seventh. The first voyage adds up to about a megabyte and a quarter more, its own music and the sound effects. That figure is this build’s own files compressed locally on 25 September 2026 rather than a reading taken off the wire, so what Cloudflare actually serves may differ a little. It also leans on the browser rather than the phone’s graphics chip, so an old laptop or a weak connection will feel it, and the first load is slower than the second because nothing is cached yet. There is no installed version to fall back on yet. There is more about the game, including what it costs and what it collects, on its own page.
