Get ready for a fast-paced number challenge with CoinSum! A falling coin holds a target number, and your goal is to find the two numbers at the bottom that sum up to it. Think fast and tap faster before the coin hits the bottom! The clock is ticking (or rather, the coin is falling!), and the faster you solve the sum, the more points you'll earn. As you score more, you'll level up, and the coin will fall even faster. Can you keep up with the increasing speed and challenge your brain? CoinSum is easy to learn but hard to master. With two difficulty modes, Easy and Hard, it's perfect for both quick casual sessions and intense challenges.
