Theme: Triple Threat

Author/Opus: This is the 28th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: In this variation of Tapa, the wall is in the form of a single non-intersecting loop. Clues inside the grid represent the number of neighboring cells visited by the loop; if there is more than one number in a cell, each number should be represented with a separate loop segment. There is no 2×2 rule of Tapa in this puzzle. This example image should help:

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. Separate each row’s entry with a comma. For the example, this would be “11,12”.

Theme: Clue Symmetry

Author/Opus: This is the 27th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Divide the grid into some regions formed of edge-adjacent squares. Each cell is part of one region, and each region should contain exactly two given numbers. Each region must have an area that is strictly between those numbers (This means, for two number clues A and B with A < B, the area C fulfills A < C < B).

Answer String: Enter the number of cells in each connected group (between bold lines) in the marked rows. For the example above, this is “34,121111,4111”.

Theme: Clue Symmetry and Logic

Rules: Hybrid of Easy as ABCD and Japanese Sums puzzle types. Fill some cells with digits 1-5 so that each row and column contains each digit from 1 to 5 exactly once as well as two empty cells. Numbers outside the grid indicate the sum of all digits in the first connected group in that direction as in a Japanese Sums puzzle. For example, the row X345X12 could have a 12 clue on the left or a 3 on the right. Or see here.

Answer String: Enter the marked rows from left to right, separating the two rows by a comma. Use an X (capital letter) for each empty square.

Theme: Grandmaster Puzzles (GMP in the shapes)

Rules: Divide each of the three shapes into four pentominoes so that all 12 pentominoes are present exactly once across the three shapes. An inventory of pentominoes is given below the puzzle; rotations and reflections of these shapes are allowed.

Answer String: Enter the capital letters for the pentominoes sitting in each cell along the indicated long row. Enter as a single string of 14 characters.

Theme: Logical

Rules: Place a digit from 1-7 into each circle so that no digit repeats within any straight line. The clues given inside some triangles represent the sum of the digits in the triangle’s three vertices. Or see here.

Answer String: Enter the digits in the marked lines in the direction of the arrows, separating the two lines with a comma.

Theme: Clue Symmetry and Logic

Rules: Blacken some cells and then draw a single non-intersecting loop through all remaining white cells. Outside clues indicate the size of all groups of blackened cells in that row or column in order. There must be at least one white cell between each of these groups. When no clues are given, any number of cells may be shaded in that row/column. Or see here.

Answer String: For each marked column, enter the length in cells of the longest vertical segment. Enter 0 if there are no vertical segments. Enter these values as a single string (eg “230124”).
