Rules Shade some cells, so that all shaded cells are connected by edge. Clues indicate the number of shaded cells in a room. There can’t be more than three shaded or unshaded cells in a row, i.e., no I-tetromino can fit fully inside the shaded or unshaded cells.
I should be writing up my experience in Kirchheim from two weeks ago, where I managed to beat Ulrich Voigt to take my first German title. Instead, here’s a Geradeweg puzzle, to serve as an advertisement for the Puzzler’s Club contest at LMI next weekend. The contest will feature two puzzles of mine (a Geradeweg and a Checkered Fillomino), next to a number of great puzzles by other authors.
David Millar of thegriddle.net came up with a neat new type recently with Times Zone. It’s a hybrid of latin square and loop puzzle, where the numbers inside the loop (in the “times zone”) form products while the numbers outside form sums. Check out the Intro to Times Zone for detailed instructions and a walkthrough. Here’s one I made, enjoy:
Rules Fill the grid with digits 1-6, so that each row/column contains each digit exactly once. Furthermore, draw a single loop along the grid lines that doesn’t touch or cross itself.
The loop divides each row/column into groups of digits. Each such group of digits corresponds to a number; it’s the product of these digits if the group is inside the loop, and the sum otherwise. Clues outside the grid describe the groups in that row/column in the correct order; an asterisk (*) stands for an arbitrary amount of groups, including no group at all.
Here’s a new loop type. You can solve and check your answer over here. (Let me know if that works for you and is useful, very much work in progress.)
In other things:
- I’ve worked on puzzle-draw a bit; there’s now an incomplete and experimental more generic input format, which should eventually allow you to draw graphics for non-hardcoded puzzle types. Including doing things like using other symbols instead of numbers where number clues are currently expected.
- Be sure to take part in the Puzzle Grand Prix next weekend, authored by Jonas Gleim and me. There should be some nice puzzles in there. Check out the instruction booklet.
- We’ve published a puzzle book via the German Logic Masters, with a chapter of Minesweeper puzzles by myself. There’s a number of prominent constructors involved! (It’s not really being marketed to expert puzzlers, which I suppose explains that the publisher doesn’t even bother to note the involvement of serial world champion Ulrich Voigt.) It’s claimed to be available already, though there’s some information it won’t ship before March. Have a look inside at topp-kreative.de or check it out at amazon.de or amazon.com.
Finally here’s the puzzle:Rules Draw two loops that consist of horizontal and vertical segments. One loop goes along the grid lines, while the other loop goes from cell center to cell center. Clues indicate how many of the (up to) four adjacent edges have an intersection of both loops.
