Rubber Stamp Game
by Tim Boester
Fill every blue block with a pattern from one of the stamps (the 4x4 colored grids). When the puzzle is
solved successfully, the number of shaded squares in each row and column totals the number at the end of
that row or column. Each stamp can be rotated, but not inverted, just like a regular rubber stamp. Be sure
to fill in every blue block with only one stamp. The square already shaded must be shaded as part of a
stamp in the completed puzzle.
