One great gift idea for your crossword puzzle-loving boyfriend would be a customized crossword puzzle with clues tailored to your relationship. You could create a crossword puzzle using an online template or software, and fill it with clues that relate to your shared experiences, inside jokes, and favorite things.
Alternatively, you could buy him a crossword puzzle book or subscription to a crossword puzzle service, such as The New York Times Crossword, to challenge and entertain him with new puzzles daily. Consider pairing the crossword puzzle book or subscription with a set of nice pens or a personalized notebook for him to record his progress and answers.
Or you can get him a star map with the date when he was born.
