Standard Sudoku rules: Insert a number from 1 to 6 into each cell so that no number repeats in any row, column, or bold region.

Also, there are some numbered shapes that must be put into the grid. Shapes can be rotated, but cannot be reflected.

For automatic solution checking, the numbers must be entered in green, blue, or red.
