PDF

Theme: V for Victory

Author/Opus: This is the 281st puzzle from our managing editor Serkan Yürekli.

Rules: Standard Kakuro rules. Also, a white circle between two cells shows that the digits in those cells are consecutive (i.e., they differ by 1). A black circle shows that the digit in one of the cells has twice the value of the other. If there is no circle between adjacent cells, neither of these properties holds. (Note: between 1 and 2, either a white or a black circle can be given.)

Nanro by John Bulten

PDF

Theme: Mirror

Author/Opus: This is the 67th puzzle from our contributing puzzlemaster John Bulten.

Rules: Variation of Nanro. Label some cells with numbers to form a single connected group of labeled cells. No 2×2 group of cells may be fully labeled. Each label number (including black given numbers) must be equal to the total count of labeled cells in that bold region, and all bold regions contain at least one labeled cell. The given numbers in gray indicate how many cells are labeled in that region (but not necessarily which cells are labeled). When two label numbers are orthogonally adjacent across a region boundary, the numbers must be different.

Difficulty: 2 stars

Time Standards (highlight to view): Grandmaster = 1:45, Master = 3:00, Expert = 6:00

Countdown Tapa: 8 Days to Go

To enable our June reopening, Serkan Yürekli has stepped into a role as Managing Editor for the site. Serkan now oversees our puzzle submission and review process, assembles the web weeks, and has also brought new ideas for puzzle packet formatting, books, and other things you’ll see as we re-launch. As one small example, while we have always had an escalating set of puzzle difficulties from Monday to Saturday, we are now going to try to put star ratings (out of 5) on all puzzles for more comparison across weeks. We’re quite excited to have Serkan step into this larger role, and hope it increases the quantity of puzzles we can release without any change in the quality you have come to expect from GMPuzzles.

Enjoy this challenging Tapa (False) variation from Serkan as we count down the 8 days remaining.

Tapa (False) by Serkan Yürekli

PDF

Theme: 8 (or 2 cubed)

Author/Opus: This is the 280th puzzle from our contributing puzzlemaster — and new managing editor — Serkan Yürekli.

Rules: Variation of Tapa rules. All clue digits are false and should be either one higher or one lower than the value given. (Note: Some corrected clue sets may be identical to their uncorrected versions, e.g. 1 2 becoming 2 1. Some corrected sets may contain zeroes, which have no effect on the remainder of the clue set.)
