Sudoku Variation by Craig Kasper

PDF

or solve online (using our beta test of Penpa-Edit tools)

Theme: Dalek Invasion

Rules: Standard Sudoku rules except that instead of the numbers 1-9 this puzzle uses the letters in “END MATRIX”. Also, clues in the grid represent typical “Seek and Spell/Kanaore” clues; specifically, it must be possible to read each of the words/phrases listed below the grid by starting at the indicated number, moving one cell in the direction indicated by the arrow, and then continuing to move one cell at a time up, down, left, or right to complete the word/phrase. No cell may be used more than once in a single path, but the same cell can appear in the paths of different words/phrases.

Answer String: Enter the 2nd row from left to right, followed by a comma, followed by the 6th row from left to right. Use all capital letters.

Ask Dr. Sudoku #13 – Puzzle Hunting

A few weeks ago Giovanni P. asked what our visitors might think about “other puzzles.” His question was specific to word puzzles, but this week I put the question to the test when I posted our first “Puzzle Hunt” puzzle. The Monday puzzle was not announced as such. Instead it was meant to just look like an April Fools joke. But it already has the most FAVEs of any puzzle on the site. So what are “Puzzle Hunt” puzzles and what was really going on with that word search?
