Countdown Game Solver is an app that brings the popular "Numbers" portion of the British television show Countdown to your iPhone or iPad. It offers a Scrabble-like tile game where you can drag numbered tiles onto the game board to create arithmetic expressions that match the target number or come within ten of it.

With over 11 million unique starting configurations, you'll never run out of puzzles to solve. The app also includes a Universal Solver that can find all possible solutions for a given initial configuration within seconds. If no solution is found, you can be confident that no solution exists.

The Universal Solver is smart enough to recognize near-duplicate solutions and remove them from the list, ensuring that the solutions provided are manageable. Additionally, Countdown Game Solver is fully integrated with Apple's Messages app, allowing you to share your accomplishments and challenge your friends.

This app is a single universal app that runs on all iOS devices, including iPhone, iPad, and iPod touch. It's a great way to test your math skills and have some fun on your mobile device.
