Theme: Clue Symmetry and Logic

Author/Opus: This is the 184th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Standard Cave rules. Also, the Cave must be divisible into pentominoes. Not all pentominoes need to appear, and pentomino shapes can be used more than once. As in Pentominous, no two identical pentominoes can share an edge.

Answer String: Enter the letters associated with the pentominoes occupying each cave cell in the marked rows, separating the rows by a comma. Use CAPITAL LETTERS, and ignore non-cave cells (Example: “WXXXT,LLUU,PPPULUF”).

Time Standards (highlight to view): Grandmaster = 3:45, Master = 5:15, Expert = 10:30

Theme: Pi

Author/Opus: This is the 183rd puzzle from our contributing puzzlemaster 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.)

Answer String: Enter the values in each cell in the 4th row from left to right and then in the 8th row from left to right, separating the two entries with a comma. Ignore black cells.

Time Standards (highlight to view): Grandmaster = 5:15, Master = 6:30, Expert = 13:00
