Here’s a Divisor Sudoku. I made this one for the 24h review series on croco earlier this year, but ended up making a second easier one. Please excuse the lazy rendering.
Rules Standard Sudoku rules. In addition, the givens indicate a divisor of the corresponding two-digit number (left-right or up-down).
A companion skyscrapers puzzle to puzzle 119. This was the first one I made, 119 was meant to be easier, but still too hard.
Buildings of size 1-9 and one park (gap, invisible) per row and column.
EDIT fixed shifted clues along the top.
Have a Summon. If you’ve already figured out the kind of argument this one is built around it’s not that difficult.
And quickly another post to hide that terrible Domino Construction. In contrast, this one has a nice solving path, but will you find it?
Rules Solve as a standard Slither Link. In addition, all cells outside the loop must be connected, and there must be no 2×2-square of cells that is entirely inside or outside the loop.
Or see the instruction booklet.
Is it just me, or are there more uncommon types on this round than previously? Anyway, below there’s a Skyscrapers Domino Construction. Again these were on the 24 hours this year. This one is probably not typical, but I think it came out quite well.
Rules Place the given set of dominoes in the marked domino tiles. Whenever two dominoes touch by an edge, the adjacent numbers must be the same. Clues outside the grid are skyscraper clues: They indicate the number of visible skyscrapers when looking along the corresponding row or column from that point, where each number represents a skyscraper of that height. Skyscrapers are blocked from view by those of greater or equal height.
Or see the instruction booklet.
Continuing with the GP practice puzzles, here’s a Paint By Threes. I believe I’ve seen these more than once at the 24 hours, see Puzzle 121 for a link to the 2016 puzzles. There were a few on croco, too: Dreier-Nonogramm 1, Dreier-Nonogramm 2, Dreier-Nonogramm 3. I tried to make this one a bit harder.
Rules Replace each circle with a non-zero number, divisible by three if and only if the circle is black. Then solve as a standard nonogram. I.e., shade some cells, such that the clues give the sizes of all blocks of shaded cells within that row or column, in the correct order.
Or see the instruction booklet. (In the competition presentation, white/black circles are replaced by white/gray squares.)
