Yes. Bluewater is free to play in your browser with no download, no install and no account. It runs on desktop and on phones, and your boat, cash, gear and Record Book are saved locally so you can close the tab and pick the next trip up where you left it.

Work the lure with short taps until something bites - the hook sets itself. Then hold anywhere on the water (or the up arrow) to gain line and let go to give line back. Keep the tension bar out of the red; when the ring around the fish turns red, let go. Each species needs a different pattern: let a runner run, hold a diver hard, keep a head-shaker in the middle of the bar, and go slack when a jumper telegraphs a leap. A tired fish comes to the boat and is taken aboard by itself.

The line only breaks because you are pulling on it. The drag pays out line on its own when the load gets high, but it cannot keep up with a big fish in a full run - if you are still holding through that run, the tension climbs past what the line can take. Let go while the fish runs, and reel again when it stops. When a line parts the game shows the fish weight and the line strength that would have held it; heavier line at the dock raises the limit, at the cost of fewer bites.

Land all eleven species to complete the Record Book - that is Campaign Complete. The rare ones live deep and show up later in a trip, so you need spool upgrades to reach them and the right lure: each page of the book lists which lures raise that fish. Nothing at all rises in the Trench except to the Lamp, and the oarfish is the last and rarest page.

Yes. The whole game is played with one thumb on the water: tap to work the lure, hold to lift it or reel, let go to give line. Two buttons stay on screen - DIVE to sink the lure and Lure to change it. On a phone the view is upright and on a desktop it is wide, and the game fills whichever shape it is given.
