First Impression

by George Barany

This "mid-week level" puzzle (13x13) was conceived in the middle of a challenging procedure, and is dedicated to my new dentist. In addition to the theme, which channels a personal story, there are several bonus entries that might amuse you.

Click here to view or download the puzzle in PDF format; here to download it as a puz file [requires Across Lite software to play]; here to solve the puzzle interactively (thanks to Jim Horne); here for the solution. I would like to thank Christopher Adams, Barbara Barany, Martin Ashwood-Smith, John Child, Noam Elkies, Charles Flaster, and Martin Herbach for helpful test solving and suggestions.
