Theme: RANDY (for patron Randy Rogers)

Author/Opus: This is the 112th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Kakuro and Easy as ABC. Enter a single digit from 1 to 9 or letter from R, A, N, D, Y into each cell so that each full row and column contains each letter exactly once. A number clue indicates the sum of the digits in the across or down entry. No digit is repeated within an entry (but digits may repeat within a full row or column). A letter clue indicates the first letter seen from that direction after the clue. (For clarity, all letter and number clues point down or right except for the letter clues on the bottom/right edges of the entire grid which point up/left.)

Answer String: Enter the values in each cell in the marked rows from left to right, separating the rows with a comma. Ignore black cells and USE CAPITAL LETTERS.

Time Standards (highlight to view): Grandmaster = 25:00, Master = 42:30, Expert = 1:25:00

Serkan finished this “Giant” puzzle shortly after we started our break. We figured this Gapped Kakuro would be a fun, challenging Sunday Surprise that might take several Sundays to complete.
