<![CDATA[Puzzle 71: Checkerboard Insanity]]>Tapa Region Party Follow regular Tapa rules: Do Nurikabe-style. (The black cells are called the Tapa wall.) Cells with numbers may not be black. Numbers in a cell indicate the sizes of the black square groups adjacent to the clue square; two separate black square groups must be separated by at least one white square.

In addition, Region Party variation apples. The two quadrants with blue cells and “C” at the top-left of the cells indicate Clones quadrants: The contents of the two quadrants must be identical on the blue cells. (There is no restriction for cells inside the quadrants that are not blue.) The two quadrants with red cells and “E” at the top-right of the cells indicate Extra Region. After tilting the grid by 45 degrees, the blackened cells on the red squares also form a Tapa wall. (Note that all red squares form a single region, not two separate regions.)

Puzzle 71: Tapa Region Party

Puzzle 71: Checkerboard Insanity
Tapa Region Party

Perhaps the only puzzle among the most recent 20 or so that is made purely on computer, not using my puzzle scratch book. The difficulty is hard; I wanted to go with medium but the variant is pretty confusing on itself.

Anyway. What inspired me? The recent TVCs and CTC on LMI, of course. Plus me recalling that I’ve done this crazy variant before. :3

And…uh…this variant is hard >_< The best finish I’ve found is unsatisfactory. But fair enough for a puzzle I make in half hour or so.

I need to make some easy puzzles for my “mate”… Ideas?
