These groups can consist of a single cell or multiple cells. Both of a region's groups must have the same size and shape, but may be rotated or reflected. Shaded groups may not be orthogonally adjacent. Cells with arrows are not shaded, and indicate the size of a group of shaded cells which occupies the adjacent cell in the indicated direction(s). (Note: a 2 in a cell with two arrows would indicate that there was a region of size 2 in BOTH directions.) For each region whose shaded groups consist of multiple cells, one shaded group must contain a set of consecutive digits in any order, and adjacent digits within the other shaded group must differ by at least 5. The solver must determine which is which.
