How to play
- Goal
- Cover every open tile exactly once with straight arms from the numbered towers.
- How it ends
- A chart is won when every open tile has one wind and each tower covers exactly its number; there is no loss.
- Record
- Your first clear time stays in this browser; the fastest verified first clear appears beside it and on the page trophy.
- Tap a numbered tower, then tap the last tile of a straight arm in its row or column. You can also drag from the tower to that endpoint. A tower can have several arms, but their combined lengths must equal its clue; the tower tile itself does not count.
- The worked picture is real Chart 001: its tower marked 6 sends four tiles north and two west. The six open tiles are covered; the numbered tile is excluded. Tap an arm’s endpoint again to lift it, or choose a shorter endpoint to retract it.
- Winds cannot overlap, cross or enter another tower. Every open tile must have exactly one wind. The chart finishes automatically when the clues and full cover are correct.

About Four Winds
At a windward shrine above Orenvalt’s floating islands, send straight rune winds from numbered towers. Each tower may reach north, east, south and west; its number counts the open tiles its arms cover.
Every open tile needs exactly one wind. The 160 original charts have one independently verified answer each, and a separate deduction pass completes them without guessing.
All shelves are open. Undo, Redo and Restart let you revise a chart; the first clock continues through a return visit, while finished charts can be replayed as practice.
