Ratio Craft is an exciting puzzle game designed for Android users, combining mental math with fast-paced logic challenges.

The objective is to select combinations of numbers that total exactly 7, triggering bursts that clear the spheres and boost your score. This gameplay encourages quick thinking and strategic planning, making every decision crucial as you race against the clock.

The game introduces a 'Lucky 7' mechanic, where exceeding the sum of seven results in a penalty, shaking the spheres and resetting progress. With a constantly diminishing timer, players experience mounting pressure to perform swiftly and accurately. From simple equations like 3+4 to intricate multi-sphere combinations, Ratio Craft offers a rewarding mental workout that challenges players to enhance their skills while aiming for the title of Lucky Seven Master.
