How Conflux works

Rain falls on every cell of the watershed. Slopes pass it along; pools collect it. Your job is to turn every slope so the water moves and every pool ends up exactly full.

  1. Pools are the numbered cells. The number is how many cells drain into that pool — counting the pool itself.
  2. Slopes are everything else — you can spot the turnable ones by their dashed ring. Tap one to turn its arrow clockwise; long-press (or right-click) to turn it back. Solid grey arrows are carved in stone — they never move.
  3. Water follows the arrows, cell after cell, and must always reach a pool. Arrows may never chase their own tail.
  4. The ring around each pool fills as you route water to it. Exactly full is right; overfull is a flood.

When the whole board drains and every ring sits exactly on its number, the watershed settles — and you win.
