Note that our solving widget/fave button is being fixed over this week and may temporarily be inaccessible; hopefully after the update is complete the issue that was keeping some people from logging in will be resolved. We will share more info when we know all functionality is working again.

This past week’s set of Tapa puzzles are collected in this PDF and the solutions are in this PDF.

The daily solution videos are on the posts and also linked below. We’ve been getting some helpful feedback on what you like about these videos as well as things we can be doing differently; please feel free to share your own comments as we continue to make these. We will eventually be making tutorial videos for how to use Penpa-Edit for each style, but as the interfaces are still being improved we have not done this for any genre yet.

This upcoming week will feature Sudoku puzzles and variations. We also expect to be releasing The Art of Sudoku 2 next Sunday. This long-awaited book features 180 hand-crafted sudoku puzzles, including 60 classic Sudoku, 20 Tight Fit Sudoku, 20 Consecutive Pairs Sudoku, 20 Even/Odd Sudoku, 20 Thermo-Sudoku, 20 Arrow Sudoku, and a variety section with 20 other Sudoku of different styles. We’ll be selling it as a complete collection or as three partial packs split out by sections (Classic only; Tight Fit + Consecutive + Even/Odd; Thermo- + Arrow + Other).

Author/Opus: This is the 193rd puzzle from our contributing puzzlemaster Murat Can Tonta.

Rules: Standard Tapa rules. Also, similar to Nurikabe, each Tapa clue cell is part of an island of horizontally and vertically connected white cells and the area of the island must be one of the numbers in the clue (as an example, if a clue is 1 5, then the island containing that clue must be either 1 cell or 5 cells large). Islands are allowed to touch diagonally, and there may be islands without any number clues in the grid.

There were 33 correct submissions out of about 40 entries. The three randomly selected winners, who have each won an e-book from Prasanna Seshadri, are Yossi Fendel, Tom Luo, and Arthur Nebout. Congratulations to these three, and we hope you all enjoyed the puzzle!
