Normal sudoku rules apply. The grid is partially covered in fog. Placing correct digits will clear fog from surrounding cells. 𝗖𝗮𝘃𝗲: Shade some cells such that all unshaded cells form a single orthogonally connected region and all shaded cells are connected to the edge of the grid. Digits in circles either give the size of the shaded region in which it lies or the total number of unshaded cells which can be seen in all directions from the unshaded circled cell, including the cell itself. Shaded cells block vision. 𝗟𝗶𝗻𝗲 𝗖𝗼𝘂𝗻𝘁: Some circled cells are endpoints of lines in the grid. All lines move orthogonally. Lines do not cross or branch, except at circled cells. The digit in a circle gives the total number of cells along each line attached to the circle of the same shading as the circled cell, including the endpoints. 𝗦𝗽𝗹𝗶𝘁 𝗣𝗲𝗮𝘀: Digits along a line strictly between two circles must sum to a two-digit number, where the tens digit is in one circle and the ones digit is in the other. Digits separated by an X sum to 10. Digits separated by a V sum to 5. Not all X or V are given.
