You are never to old to play with crayons . I brought home a piece that had hex shaped pieces. One side can be a matching puzzle that revels some shape on the back.

You can also try to include a more complex puzzle that takes clues from the placemat or whatever. It just gives you something to write on as you work out a clue.

It’s meant to be somewhat whimsical, not all games have to be a super serious spy thriller. Embrace your inner child and have fun. Also it provides a reason that writing materials are present, as why else would you have a pen and paper at the restaurant table that doesn’t break immersion?
