Number Crunch is a free browser-based math puzzle game inspired by the Countdown numbers round. Given 6 numbers and a target, combine them using addition, subtraction, multiplication, and division to reach the goal. With three difficulty levels (Easy for small numbers, Medium for mixed, Hard for large numbers and high targets), multiple rounds, a 60-second timer, and an undo system, it provides an engaging mental math challenge. No downloads required — play directly in your browser on any device.
Number Crunch is a fast-paced mental math game that tests your ability to perform arithmetic under time pressure. Each round presents a target number and a grid of smaller numbers that you must combine using addition, subtraction, multiplication, or division to reach the target. Think of it as a speed version of the Numbers Round from Countdown. The clock is always ticking, pushing you to spot number combinations quickly rather than calculating slowly. Multiple difficulty levels adjust both the complexity of the target numbers and the operations required, making it accessible for beginners while still challenging for math enthusiasts. Regular play noticeably improves mental calculation speed and numerical intuition, skills that transfer directly to everyday situations.
