➕ Countdown Calc
Combine five numbers with plus, minus, times, and divide to land as close to the target as you can.
How to Play Countdown Calc
Goal: get as close to the target number as possible — exact is best — by combining the starting numbers.
Controls: select two numbers, then click an operator to combine them into one new number. Keep combining, then click Finish when you're happy with your closest result.
Tips:
- Division only works when it comes out even — plan pairs that divide cleanly.
- The large number (25, 50, 75, or 100) is usually your best lever for closing a big gap fast.
