SUMO Number Puzzle Turns Mental Math Into a Free Mobile Game

SUMO, a free number puzzle now available on iOS and Android, reduces its rules to a single sentence: select the right squares, add up their values and reach the target shown on screen.

The mechanic is easy to grasp within the first minutes, but finding the best route takes thought, logic and planning. According to the developer, the game grows more demanding as levels advance, with foresight and strategy becoming decisive.

Built for a wide audience

SUMO is aimed at children, students, adults and anyone who wants to keep their mind active. Each level is designed to balance fun, strategy and cognitive training, and the developer says regular play helps build attention, numerical fluency and problem-solving skills.

The listed features include a simple, intuitive tap-and-add mechanic, gradual difficulty, and mental-arithmetic and concentration practice. The interface is clean, with soft colors meant to create a calm, pressure-free experience.

Availability

On the App Store, SUMO is listed under Games, Education, Puzzle and Quick Games, and the current iOS version is 1.2. On Google Play it appears under the name "SUMO: Math Number Puzzle".

The developer describes the game as more than entertainment: a chance to strengthen the mind at your own pace and without pressure. For players who like quick puzzle sessions with a light educational angle, it is a free option on both major mobile platforms.
