Countdown

Reach the target number by combining five numbers with +, −, and ×. Each number can be used once, and you don't have to use them all.

      How to play

      1. Choose how many big numbers you want. You get five numbers and a target between 101 and 999.
      2. Click a number, then a second number, then +, −, or ×. The two numbers are replaced by the answer.
      3. Keep combining until one of your numbers matches the target. Subtraction always takes the smaller number from the larger.

      Keyboard: 1–5 picks a number, + − × (or x) picks an operation, Esc cancels a pick, U undoes.
