Sunday Update and Solutions

For those that missed it, we released a new e-book TomTom last Sunday. It is a great collection from four of our puzzlemasters for this number placement style. We are working to complete two 25-puzzle Sudoku variation packs this month and will then release our first edition of a quarterly puzzle mix magazine late in August. As we’re finding we are on track to release 12 books this year (about one a month), we’re considering restarting a subscription option for people to get some/all of our book content at a discount. Please watch this space for more info in the coming months and, as always, share any feedback you have with us on our puzzle collections.
