Countdown Tapa: 8 Days to Go

To enable our June reopening, Serkan Yürekli has stepped into a role as Managing Editor for the site. Serkan now oversees our puzzle submission and review process, assembles the web weeks, and has also brought new ideas for puzzle packet formatting, books, and other things you’ll see as we re-launch. As one small example, while we have always had an escalating set of puzzle difficulties from Monday to Saturday, we are now going to try to put star ratings (out of 5) on all puzzles for more comparison across weeks. We’re quite excited to have Serkan step into this larger role, and hope it increases the quantity of puzzles we can release without any change in the quality you have come to expect from GMPuzzles.

Enjoy this challenging Tapa (False) variation from Serkan as we count down the 8 days remaining.
