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.

Theme: Up to Eleven (for patron Phleb)

Author/Opus: This is the 111th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the words into the grid (one letter per cell) so that they do not touch each other, not even diagonally, and so that they can be read in a straight line in a vertical or horizontal direction. Some letters in the words are already given in the grid. Then find a path that passes through every cell of the grid, starting with the first letter of the first word, passing through the words in order from their first letters to their last letters, and ending at the last letter of the last word. Ignore the black cell.

Or see this example:

Answer String: Enter the number of turns the path takes between each of the words in order as a single string of numbers. (Ignore turns in cells with letters.) The answer for this example is “224”.
