June 1st will be the reopening of GMPuzzles. In recent years we have had on weeks and off weeks, but with this relaunch we are planning to have content every week. Monday through Saturdays will be new puzzles, with increasing difficulty throughout the week. There will be a mix of variety weeks and single puzzle genre weeks. On Sundays we will be releasing solution images for all of the puzzles, as well as a solution video walkthrough for one of our puzzles. While these solutions have historically been “rewards” for our subscribers, we hope that sharing them more broadly will help expand our community and help people learn how to solve our hardest puzzles.

We’ll have info on some other changes soon; for now, enjoy this Countdown TomTom.
