Schedule for Next Week

All the puzzles from last week have been grouped in this PDF. While we don’t like breaking the rules too often, we hope you enjoyed last week’s “Oddities”. Even the bonus puzzle, the “Nothing Odd Going On Here” Slitherlink, was quite twisted in its execution.

Next week will focus on one of our favorite puzzle types: Fillomino and variations. Puzzles will be by Grant Fikes, Prasanna Seshadri, and Serkan Yürekli. The bonus puzzle will also be from that category, and if our high-level supporters haven’t had their Fillia of puzzles yet, there will be an extra large and rather incredible puzzle sent out by Grant Fikes as well.

The Best of Both Worlds?

While we tend to focus on “paper puzzles” here at Grandmaster Puzzles, this coming year we will make a dedicated push into the puzzle game app space.

Today we wanted to show you a promo image for our first game. It combines one of our strengths (TomTom) with the best of 2014’s puzzle apps (namely, Threes! and 2048).

Can you find the one solution?
