Ripple

Somewhere in the grid are hidden sources. Every number tells you how far it sits from the nearest one. Find them all — and you never have to guess.

The rules, in one paragraph

  1. There are K hidden sources in the grid. Their positions are not shown.
  2. Each number on the board is the Manhattan distance to the nearest source — the number of steps up, down, left and right.
  3. Mark all K sources. When the last one is placed, the puzzle verifies itself.
  4. Every board has exactly one solution and can be reached without guessing.
