Fillomino: Divide the grid into regions and fill each cell with the size of the region (in number of cells). Regions of the same size cannot share a cell edge. One region border (between R10C8 and R10C9) is given. A number appearing in a circle indicates how many times that number appears outside of circles. (There is no limit on numbers that never appear in circles.) Note for solution checking: if any regions larger than 9 cells appear, enter the region size's units digit into its cells.
