Tap Set Sail, choose one of the five seas and select its first stage. Later stages unlock in order within that sea. Complete stage ten to continue to the next sea, or return to the hub and choose another mode.

Boat Escape: release boats in a safe order. Palm Harbor: turn route markers and match docks. Coral Tides: sending a boat, turning a marker or tapping Wait changes the tide; match your route to the open channel. Cargo Harbor: clear boats and deliver orders on time. Coast Defense: deploy and merge defenses, then aim cannons and rockets on the sea.

Tap Xiaohang or the help button to read the current idiom, its meaning and the task. In Coast Defense, tap Prepare, then Xiaohang in the pause panel. Replay the narration there. Instructions pause play; English mode retains the original Chinese idiom and explains it in English.

Open Settings and check music, sound effects and voice separately. Check the music volume, device volume, silent mode and connected headphones. Music accompanies Coast Defense stages and the first Boat Escape stage; other navigation stages use sailing effects. Other audio apps and interruptions may pause game music.

Read the current stage briefing because modes differ. Navigation and Cargo stages fail at their time limit. Restarting is free. From stage 3, a voluntary ad can grant 30 extra seconds for Navigation or 25 for Cargo. Cargo also accepts a revive token, sharing one continuation per attempt with the ad. Continued wins earn up to two stars. Coast Defense is won by repelling all its enemy waves. A ship reaching the defense line ends the battle, but one optional ad per run can revive you in place, keep your defenses and grant 200 battle coins. You may always restart for free.

Drag a weapon to one of the six positions. Matching weapons can merge up to five per position, increasing the firing rate. Each weapon keeps its base power. Machine guns and nets attack automatically; select a cannon or rocket and drag on the sea to aim. Tap Prepare to pause, claim optional ad equipment, or reorganize. Radar costs 1000 battle coins or one optional ad and extends range without auto-aim. Thunderstrike is fired manually: each battle offers one free use when charged or in danger; up to five optional ads each grant one bomb, and up to five more can be bought for 1000 battle coins each. Shots have a 20-second cooldown. Clearing each new Coast Defense stage adds 100 to your starting battle budget, permanently; replaying cleared stages does not add it again. Battle coins and the voyage wallet are separate.

There are no purchases or paid currency. In all five seas, up to three voluntary coin ads per run each grant 200 coins after completion. The first four seas award saved voyage coins; Coast Defense awards battle-only coins. Coast Defense also has up to five optional bomb ads and one optional radar ad per level, separate from the coin ad limit. A separate ad after a Coast Defense breach can revive the battle once per run and grant 200 battle-only coins. From stage 3, a separate timeout ad can continue Navigation for 30 seconds or Cargo for 25 seconds, once per run. After at least three completed stages, a closeable interstitial may appear before results, spaced by at least three completions and five minutes. No ad appears on first launch or interrupts active play. Unavailable or cancelled reward ads do not use a claim. Free retries remain available.

Progress is local. Keep the installed app if you want to preserve it; deleting and reinstalling may lose progress. The game does not offer its own cloud save. Apple device backups and transfer behavior depend on your system settings.
