BSEditor: Basically a 9x9 Grid is already filled in with number 1 to 9, nine times. All you have to do is to identify nine segments of nine cells each, with each segment containing numbers 1 to 9. All 9 cells in a segment must be connected in one chain. Only hint you have is that if a number in a cell and a number in any of its four neighbors (left, top, right and bottom) add to 9 then both cells will belong to one segment. There are no other rules.

Puzzles come in three levels:

1. Easy - One out of nine segments is already shown in the puzzle. And there are more of same numbers together in the grid making it easier to identify segment boundaries.
2. Hard - A segment is not ready marked. But there are more of same numbers together in the grid making it easier to identify segment boundaries.
3. Very Hard - No segment is ready marked and there are fewer placements of same numbers together.

Requirements: No special requirements
