Puzzle 534: Fencing Match 46
It has recently come to my attention that two numbers which commonly appear in these puzzles have been the intellectual property of Microsoft for over a decade. I have created this puzzle without those numbers as a result. Remember, kids, infringing on patents is bad for you!
Rules -- Solomon's Keep
Solomon's Keep was invented by the Japanese puzzle company Nikoli (under the name Five Cells – that's a transliteration, not a translation, believe it or not).
1. Divide the grid along the grid lines into pentominoes (regions containing exactly five cells each).
2. A number in a cell represents how many edges of that cell are borders of pentominoes (including the perimeter of the grid).
2. A number in a cell represents how many edges of that cell are borders of pentominoes (including the perimeter of the grid).
Puzzle 529: Ellbound 1
This puzzle appears in "Penpa 2012 by Nikoli"; when a puzzle appears outside of Puzzle Communication Nikoli's experimental section, you know it's legit. Curiously, though, none of the 20 puzzles therein exhibit symmetry.
Rules -- Ellbound
Ellbound was invented by the Japanese puzzle company Nikoli (under the name Sashigane, which refers to a carpenter's square).
1. Divide the grid into L-shaped blocks, each consisting of an elbow, a horizontal arm extending from the elbow to another cell in the same row as the elbow, and a vertical arm extending from the elbow to another cell in the same column as the elbow.
2. A cell with a circle in it is the elbow of its corresponding block. If the circle has a number in it, that number represents how many cells are in that block.
3. A cell with an arrow in it is the tip of one of the arms of its corresponding block, and the arrow points to the elbow of that block.
2. A cell with a circle in it is the elbow of its corresponding block. If the circle has a number in it, that number represents how many cells are in that block.
3. A cell with an arrow in it is the tip of one of the arms of its corresponding block, and the arrow points to the elbow of that block.
