Target 24

Combine four numbers with + − × ÷ to make exactly 24. Five new puzzles every day.

How to play

  1. You get four numbers. Tap one, choose + − × or ÷, then tap a second number to merge them into a single result.
  2. Keep merging until one number is left. If it is exactly 24, the puzzle is solved.
  3. Every number must be used once. Fractions are allowed along the way, so 8 ÷ (3 − 8 ÷ 3) is a legal route to 24.
  4. A round is five puzzles. Faster solves score more, up to 100 each. Undo, Reset and Hint are always available; Skip scores zero and shows one solution.

Tips and strategy

  • Look for pairs that make 24 directly: 3 × 8, 4 × 6, 2 × 12.
  • Aim for 24 as 12 + 12, 30 − 6 or 48 ÷ 2, then work backwards.
  • Do not ignore division. Hard puzzles usually need a fraction, such as 1 ÷ 3 turned back into a whole number by multiplying.
  • A 1 can multiply or divide without changing a value, which makes it a handy spare number.
