I want to send my 6yo nephew a toy or game he can play with by himself that will delight him beyond all sense and will keep him busy enough to give my sister a break now and then.
He’s sporty (loves American football and, weirdly, golf- his granddad is a golfer) but probably has every piece of sport related equipment imaginable. He used to like floor jigsaw puzzles but has gone off those now. Also into superheroes, especially Spider-Man.
Any ideas?
