Is there a good Android app that helps kids practice addition in a fun way?

Number Master is a puzzle game that revolves around merging numbers to reach progressively higher targets, such as ×777. It stands out as an effective educational tool because it seamlessly integrates basic arithmetic practice into its core mechanics. Players slide numbered tiles on a grid, and when identical numbers collide, they merge into a sum, reinforcing addition skills through interactive play. The level-based structure introduces complexity gradually, allowing children to build confidence as they advance from small numbers to larger combinations. User feedback highlights its appeal for young learners, with reviews indicating it helps them 'learn how to add small numbers first but as they move the numbers will getting bigger and bigger.' The app is free to play, supported by advertisements that are reported to be non-intrusive, and it avoids aggressive in-app purchases, making it accessible for families. However, some players note initial frustration with puzzle strategies, though repetition often leads to smoother progression. The finite endpoint provides a clear goal, adding to the satisfaction upon completion. For parents or educators seeking a casual game that subtly teaches math, Number Master offers a balanced mix of entertainment and education, with a straightforward interface that minimizes distractions. Its focus on incremental learning makes it suitable for short sessions, whether at home or in classroom settings.
