This is an Oasis puzzle.

From WPC Instruction Booklet: Shade some cells in the grid. Shaded cells cannot touch each other orthogonally. All unshaded cells must be orthogonally interconnected. Unshaded cells cannot form a 2x2 square. Cells with circles cannot be shaded. A number indicates how many other numbers or circles can be reached from that cell by passing only orthogonally through empty unshaded cells (it cannot pass a shaded cell nor a cell with a number / circle).

### Puzzle 98 (Outside Kropki)

This is an Outside Kropki puzzle. This was US Team practice for the 2016 WPC.

From WPC Instruction Booklet: Fill in the whole grid with digits 1 to N (where N is the size of the grid) so that each row and column contains each digit exactly once. If there is a white dot between a pair of orthogonally adjacent cells, then the cells must contain numbers whose difference is exactly one. If there is a black dot between a pair of orthogonally adjacent cells, then the cells must contain numbers whose quotient is exactly two. There can be either a black dot or a white dot between 1 and 2. All dots from each row and column have been removed from the grid. They must appear in the corresponding row or column in the given order. There may be some gaps between the circles. All possible dots have been given.
