About

GreatMaxMath

Features
Read full description

A casual puzzle game with a gentle art style, helping you practice your observation and mental arithmetic skills in short bursts of free time. The game includes three gameplay modes: matching identical numbers to eliminate them, merging adjacent squares (with a sum not exceeding 9), and clearing all selected squares when the sum is 10. After elimination, pieces will fall due to gravity and replenish with new numbers, constantly changing the board. Consecutive successful eliminations trigger combo bonuses; higher levels offer more diverse number combinations, increasing the challenge. A built-in tutorial and explanations of each mode make it easy to pick up and play. Earn coins through daily check-ins and level completion, which can be exchanged for hints and shuffling items in the shop. Data statistics and a random mode are also provided, allowing you to switch up your gameplay anytime and keep your mind sharp in a relaxed atmosphere.
