Normal sudoku rules apply. Draw 12 orthogonally connected regions of different sizes which do not overlap. The regions do not need to cover the entire grid. Within a region, a digit may only repeat if it appears on a gold ring, in which case it can only appear on gold rings. A digit on a gold ring indicates the number of gold rings within its region. A digit on a pear tree is equal to the number of cells in its region. The 3 digits on red baubles sum to 25.
