GMS sends out a monthly puzzle that is NEVER as straightforward as I think, and usually takes me a couple of days and more than one "aha!" moment to complete. I love how creative the various parts to these puzzles are, everything from a cassette tape to a coffee mug to mysterious phone numbers with cryptic answering machine messages. It's so much fun to have physical clues to manipulate, and that sets this puzzle subscription apart. I gave GMS as a gift to my daughters (and their husbands/partners), a friend and his wife, and my brother and his 14 year old son. All of them have had a blast working on it together and found it, as I have, interactive, challenging, a great bonding activity, and so much fun! If you're looking for a deviously clever monthly diversion, don't look any further -- GMS is the puzzle box you want! And it’s the perfect gift for that hard to buy for know-it-all-teen, game-loving Millennial, family gamenight aficionado, or sharp Baby Boomer.
GMS consists of a monthly mailing in which you are tasked with locating fragments of Einstein's brain. The mailings take the form of a single, multi-step puzzle of above average difficulty. Because each month's puzzle is focused on a single theme/item, there could be a mailing which misses the mark for you. However, I have found those misses to be few and far between. In fact, one of the early mailings is hands down the best single puzzle I've encountered from these subscription based puzzle boxes. I would recommend that any who appreciates complex and intricate puzzles give GMS a try.
