CoreMelt is an engaging Android application designed to enhance mathematical skills through an interactive game format. Players navigate a 10x10 numerical matrix, where the main objective is to swipe and connect adjacent numbers that sum up to a prime target displayed at the top of the screen. As players successfully connect numbers, they disappear, allowing new numbers to fall into place, creating a dynamic and challenging gameplay experience.

The game requires players to achieve five successful connections within a time limit of 60 seconds to progress to the next level. As players advance, the difficulty increases, presenting higher prime targets that challenge their addition speed and logical thinking. The application also features a local tracking system for monitoring the highest level reached and the fastest connection time, providing a competitive edge to the gameplay.
