You get 6 numbers (a mix of small 1-10 and large 25, 50, 75, 100) and a target between 100-999. Combine them with +, -, ×, ÷ to reach the target. Each number can only be used once. You have 30 seconds!
1. You get 6 numbers — a mix of small (1-10) and large (25, 50, 75, 100) — and a target number between 100 and 999.
2. Click a number, then click an operation (+, -, ×, ÷), then click a second number.
3. The result becomes a new available number. Each original number can only be used once.
4. Keep combining until you reach the exact target or get as close as possible before the 30-second timer runs out.
5. Only whole positive numbers are allowed. Division must be exact (no remainders). No negatives.
6. After time expires, a solver shows one possible solution (or the closest it could find).
7. Use Undo to reverse your last step, or Submit to end early.
8. Play multiple rounds and track your exact match rate!

With a 30-second timer, built-in solver, multiple rounds, and stats tracking, it provides an engaging mental arithmetic challenge. No downloads required — play directly in your browser on any device.
Countdown Numbers recreates the beloved numbers round from the British TV game show Countdown. You receive six random numbers and a three-digit target, then have 30 seconds to combine those numbers using addition, subtraction, multiplication, and division to hit the target exactly. Each number can only be used once, and only whole positive results are allowed at each step. The challenge lies in spotting creative routes through arithmetic that others might miss. After each round, a built-in solver reveals the optimal solution so you can learn from every attempt. Whether you are a mental math enthusiast or just looking for a quick brain workout, the time pressure and number juggling keep every round exciting.
