How to play Triplets

  1. Draw regions and numbers.
  2. Each region must have one size-1, size-2, and size-3 region, being size 6 total.
  3. As in Fillomino, a number indicates the size of its own region.
  4. Two regions of the same size may not be orthogonally adjacent. Big regions of the same size can touch.
  5. A shaded cell is not part of the puzzle; some numbers and big-region borders may be placed as clues.
