Theme: The Eye

Author/Opus: This is the 70th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Fill all empty hexes with digits from 1-9 so that all number clues (in white) indicate the sum of the digits in that direction. Digits cannot repeat in any entry (i.e., any group of hexes connected either horizontally or in one of the two diagonal directions, without any black cells separating them). This no repeat rule applies even for unclued entries.

Answer String: Enter the values in each cell in the marked rows from left to right, separating the rows with a comma.

Time Standards (highlight to view): Grandmaster = 7:00, Master = 11:00, Expert = 22:00

Solution: PDF; a solution video is available here.

Theme: Clue symmetry and logic

Author/Opus: This is the 69th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Masyu. Draw a single, non-intersecting loop that passes through all circled cells. The loop can only make 120 degree turns. The loop must go straight through the cells with white circles, with a 120 degree turn in at least one of the cells immediately before/after each white circle. The loop must make a 120 degree turn in all the black circles, but must go straight in both cells immediately before/after each black circle.

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 7:00, Master = 10:45, Expert = 21:30

Theme: Logical

Author/Opus: This is the 219th puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Variation of LITS. Shade exactly four cells in each outlined region to form an S, L, I, C, or Y tetrahex. When all regions have been shaded, the following conditions must be true:
1) All shaded cells will be connected through a network of adjacent shaded cells;
2) No three shaded cells will share a common vertex;
3) When two tetrahexes share an edge in adjacent regions, they must not be the same type (S, L, I, C, or Y), regardless of potential rotations or reflections.

Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 5:15, Master = 9:00, Expert = 18:00
