Sail as far as you can in a dead straight line.

1. Aim. Drag on the globe to point your boat. Fine-tune with the compass tape or the ±0.1° buttons. The globe stays centred on you, so your course is a straight line until it goes round the back. Pinch or scroll to zoom in around your boat: up close you see the exact land your boat can hit.
2. Sail. One go per spot. Your boat follows the curve of the Earth, dead straight, until it hits land. Every island counts, so zoom in or check the close-up circle.
3. Score. Up to 5,000 points a spot. The closer you get to the longest voyage possible from there, the more you score.

Tip: a straight line on a globe looks curved on a flat map. Trust the globe, not the map in your head.

• Daily Voyage: 5 spots, the same for everyone and the same rules: close up (about 2,500 km across) with a 1,000 km guide line, like a Hard duel. A new one every midnight, ranked worldwide.
• Head to head: a duel. Both start with 50,000 HP. Win a round and you hit the other sailor for the difference in km, times your multiplier. Every round you win adds ×1 to it for your next win, with no limit: ×1, then ×2, ×3, ×4 and so on, so duels speed up as they go. Each round has a 60-second clock, and once one sailor locks in, the other has 15 seconds. There's no round limit: it goes on until someone runs out of HP. Pick Easy, Medium or Hard first: the spots are the same, but harder duels show less of the map and a shorter guide line. You can always zoom in.
• Landfall: a boat sets off from a coast. Guess which country it hits first, in 6 tries.
• Bullseye: you're given a city far away. Aim so your boat lands as close to it as you can. 3 shots, and your best one counts.
• Challenge a friend: send a link and duel live.
• Practice: random puzzles for all three games, no score. In the Voyage, switch to Explore to spin the globe and try any spot again.
