Puzzle 85: Nanro Signpost

One more Nanro Signpost.

nanro-signpost-2

Rules Shade some cells, so that all shaded cells are connected, and such that shaded cells don’t fill any 2×2 square. Clues indicated the number of shaded cells in an area; each area must have at least one shaded cell. Whenever two shaded cells touch across walls, the number of shaded cells within both areas must be different.

Or see the instruction booklet, with a somewhat different formulation of the rules.

Puzzle 55: Slovak Sums

Here’s another GP preview puzzle. It’s a bit degenerate, but maybe it’s still useful? For this type, there’s a bit more material out there:

slovaksumsRules Place digits from 1 to 4 in some blank cells, so that each row and column contains each digit exactly once. Clue numbers indicate the sum of orthogonally adjacent digits. The number of circles under a clue number indicates the number of digits involved in this sum. Or see the instruction booklet.

Puzzle 48: Aussichtspunkte

This is a puzzle I found in the depths of my puzzle folder. I probably made it after struggling with the puzzles of this type on the contest Best of HCS, which featured one that is thematically similar. EDIT Replaced by a non-broken if less pretty version.

aussichtspunkte

Rules Split the grid into 5 orthogonally connected areas of 5 cells each. The given numbers indicate how many cells within the area can be seen horizontally and vertically, including the cell itself. The givens are in those cells where this number is maximal for the corresponding area.

Or see the puzzle wiki for German instructions that include an example.

Puzzle 22: Japanese Sums and Loop

The Czech round of the puzzle GP will take place next week, the instruction booklet has been posted. Here’s a practice puzzle for one of the types.
japsum-loop

 

Rules Place numbers from 1 to 6 in some cells so that no number repeats within a row or column. For rows and columns that have clues given on the outside, these numbers correspond to all sums of blocks of adjacent digits within that line, in the correct order. Furthermore, draw a loop that visits all cells without a number, passing horizontally and vertically from cell centre to cell centre.

Puzzle 17: Box of 2 or 3

Here’s a small practice puzzle for one of the new (to me) types at next weekend’s Japanese round of the puzzle GP.

boxof2or3

Rules Group some circles into boxes, such that each box contains two or three circles, such that all circles within a box are connected by edges within that box, and such that edges don’t connect circles that belong to different boxes of the same size. Furthermore, all black circles must be boxed.
