⛵ Sail. Tap BACK, STOP, ROW, HALF or FULL for speed and swipe the wheel to steer (double-tap centres it). Tap the sea, or open the chart (the little map or 🗺) and tap a spot, to set a course, or ⚓ DOCK to be sailed to the nearest harbour (fleeing any fight; STOP takes the helm back). TOP changes the view; pinch (or the mouse wheel) to zoom; ⇄ beside the minimap moves the controls to the other side. Keys: W and S for the sail (tap for one notch, hold to run through), A and D for the wheel, Space throws a spear ahead, F does the round button's job (dock, fish, fight, the gate), C changes the view, E opens the sea chart.

🐍 Monsters. They grow as your ship grows. Name colours show strength: green is weaker, white even, red and purple stronger. Outrun those until you upgrade.

⚔ Fight. Throw spears or fire the ballista at range. Up close a fight starts: hit the weak spot, then dodge the way it shows (keys: Space fires and blocks, A and D dodge left and right). If an octopus grabs you or a serpent coils round you, hack at it fast to break free. Against ships you form a battle line and they sail past you: fire when a red mark is in the green, and change speed when one aims. Her whole fleet joins the line (the pause menu switches ship fights to CLASSIC).

🎣 Fish. Slow down at bubbling water, cast in the gold band and hold REEL.

⚓ Harbours. Sell fish, repair, buy upgrades and a bigger ship. With Oars & Crew, your crew also mend the hull at sea.

⚡ Weather. In storms, sail into a blue lightning ring for Thor's Fury. Turn your bow into rogue waves. Keep clear of tornadoes and maelstroms (FULL sail breaks free).

🪝 Boarding and treasure. With Grappling Hooks, board a ship under 40% hull to plunder or claim her. A treasure map marks an ✕: sail there, LAND and dig.

☠ Sinking. Half your cargo sinks with the wreck. SALVAGE it at the ☠ or pay a harbour crew. Upgrades are never lost.

💾 Save code. Carry your voyage to another device.

☠ Helheim. With a Drakkar, sail into Hel's Gate 🌀 far out in the Mist Sea to reach Helheim, the realm of the dead: undead monsters and draugr ships, all a little stronger (burning crabs set your deck ablaze, undead sharks feed on you: hack fast to stop them). Kills there give souls 👻 for rune upgrades, designs, the Ormen Lange and Naglfar. Each great ship opens one more rune level (VI the Busse, VII the Ormen Lange, VIII the Naglfar). Slay Hafgufa, Surtr and Nidhögg to build Naglfar; then Hel's armada comes hunting you. Hold a lair to its 5th and 10th wave for a trial reward. Hel's tithe in a Helheim harbour buys more souls for a while. The 🌅 gate beside Gjallarhöfn takes you home.

🎨 Harbours. The shipwright fits hull and sail designs, each with a small perk (slain legends leave new ones, the great ships unlock more, and some are dyed for gold alone). The jarl posts a bounty, the trader sells iron and timber, and the Busse is built once Midgard's three legends are slain.

👑 Reign. Slay the Kraken, Jormungandr and the Elder One. With ACTION BATTLES on (pause menu), ordinary beasts are fought at the helm too: they circle and dive, a red ring shows where they will strike (turn or change speed to dodge), and each kind strikes its own way: sharks bite the hull, serpents crash across the deck, octopuses drag your crew over the rail (tap FIRE fast to hack them off), crabs climb the side. Shoot them while they are up, or outrun them. Each legend fights its own way (the Kraken grabs your ship with its tentacles: cut them down and strike its eye; Jormungandr hunts you from below: dodge its red ring, then shoot its head; the Elder One wards itself: repeat its runes to break the ward, and shoot its eye when it flashes if it lifts your ship). In a small ship their young usually rise instead; now and then the legend itself does: flee! Stay in a lair and tougher ones keep rising; a slain legend can rise again, reborn and stronger.
