Magic squares, “I am a 2-digit number …” riddles and consecutive numbers all have one answer. Turn every clue into a small sum and the answer pops out.
Harder number puzzles from Olympiads: magic squares with two gaps, age puzzles, 3-digit number riddles, heads-and-legs puzzles and products of consecutive numbers. You type every answer — no options to guess from.
Magic square: get the total from a full line, then use a line through ? that has no other gap.
Ages: both people get the same number of years older.
