I didn't vote because I would have to select almost everything (except puppets).
When my son turned 4, he was SUPER into puzzles and games. He's six now, and still loves board games more than almost anything. He still loves puzzles, too, though he's turned from mostly-jigsaw puzzles to mostly-puzzle-books (mazes, word searches, word scrambles, et cetera). He also really liked (still does) legos and small figures, but not quite like he loves games and puzzles.
My daughter is 4, and I would say she chooses to play with either dolls or art supplies about 90% of the time she's indoors (she spends a lot of time riding her bike outside, as well). She likes dress-up clothes, too, but again--not by comparison to dolls and art stuff (markers, scissors, paper, glue, stickers, paint, glitter--all of it).
If your 4-year-old doesn't have a bike or scooter, my kids both get a TON of use out of theirs, so that's an idea.
